Hi louis I'm having issues making solder flow on first time use tips. I'm using T12 tips which supposedly are Lead-free but over and over I'm having issues trying to tin these tips for the first time. I normally put some colophony flux around the new tip and roll some solder wire around, put the iron at max temp and wait for it to melt then clean and tin. But by some reason I can't see solder wetting and flowing properly on the tip, I'm getting pissed. I have to clean with the brass sponge , put some flux colophony on the tip and then tin again .. over and over.. after this steps the solder wire will flow nicely, but after solder doesn't stick on the tip, by the way the tips are good quality. Also I've used 60/40 soldering wire and I noticed flows better than 63/37 you ask me why I don't f***ing know. I tried some 900M tips which are pure copper and this doesn't happen.

Your beloved ancient solder looks pretty easy to identify if my hunch is correct: Kester 44 series Rosin Core Solder with a 63% tin / 37% lead at a diameter of .015" in a 1 Lb. Spool, with a melt temp of 183C or 361F. You can see the 6337 in the longer number chain of 24-6337-0727 and it has a measurement of .015 to the right of that. They don't appear to make the 0727 anymore as far as I can tell after looking at their website, but the 24-6337-0007 looks pretty darn close, assuming what you have is rosin core and not solid core.

just fyi, soder fumes arent as bad as you might think. it all depends which chemical compounds are in the fumes. led for example is not absorbed by your body. it simply cannot make any chemical connection so yes you ll take it in but youll pass it out. more or less youll piss it out. otherwise anyone not using a fume extractor would have led poisining within a week. but ofc it also depends which led exactly, but usually not that big of a deal as many people think same goes for a shooting range with y lot of led fumes hovering around steeltargets, yet not a problem. however, led is not the only thing and there a ton of other chemicals within those fumes that could harm you pretty badly. so yes using a fume extractor is adviseable, and it is a health hazzard, even tough the image of a filter isnt even close to what youre really exposed to or an indicator how bad it really is. its actually the things you dont see within that filter that arent that nice to you

You are absolutely correct (~1:01:00) the human body cannot eject certain elements or combinations thereof, that enter the lungs. The atoms do not separate, so the lungs cannot absorb them. Also many of the "elements" are "barbed". Cement dust is one example I can think of. I just stays there in your lungs. Even a strong sneeze will not dislodge them. "They" just stay with you for life. Ventilation is key. Thank you Louis for stressing the importance of this issue.

the resistor mode is not that it takes time calculating it, it is because it has a capacitor charging on the circuit that you are measuring (like a +v filter cap), you are charging with the low voltage of the resistor mode that capacitor and by that changing the resistence lecture, in diode mode, it uses a higher voltage to measure, and higher than the threshold of the diodes barriers, so you are measuring the diode barriers, and any other collateral contamination like a capacitor charging won't affect the meassure because in comparison a capacitor charging is a higher resistence path for the current than a direct path through a diode or transistor in direct polarity.

I still don't know why I keep watching your videos. I'm not a hardware guy-I'm a software guy, and I still am pretty clueless about lots of the repair and hardware jargon. I think I keep coming back to your videos because it is so special and rare to find folks of a certain character on KZbin, and in life. Louis-thanks for being an inspiring and role model human being. I have been planning a KZbin channel of my own for about a year now-but I'm having a lot of trouble finding the courage to finally shoot that first episode. I keep procrastinating or doing more pre-production, like animating an opening animation, buying a 'decent' lighting setup, writing multiple scripts, planning different web and game development tutorials but..never filming! I love that you seem to jump into making your videos with, seemingly, not a lot of pre-production. They seem like videos made of whatever is on your mind at the moment-they follow the tapestry of your life. I want my video blog/tutorial channel to also have that in the moment feel, but I'm doing all this pre-production work and writing scripts. I just need to start. Anyways-thanks again Louis!

I agree completely and for the reasons you illustrated I don't know why anyone would want a much less efficient digital soldering station. Like you mentioned different situations need different temperature and what is easier,a quick turn of a knob,or pressing and holding(also remembering) a button and then beep,beep,beep.... until you get to the 1st number and then remembering which button moves to the second digit,beep,beep beep... and so on till you finished the 3rd digit. Digital settings are a backwards step if knobs are all that is needed. I have a digital Hakko and I hate it for this very reason. You are obviously highly intuitive and intuitive people care about what works,not what the status quo says is the "right" way. You have a "best" way to do things because you realize that everything is relative and there is no "right" way to fit all situations. Thanks for the great channel.

oh Louis. Thank God for this video for reference. I had bought the hakko fr-810 1.9mm tip and was using this thing for hours and kept blowing all my resistors of my board at air setting of 3 out of 9. Frustrated I went to the gym to change my mood and started watching this video again on my cellphone. As soon as you mentioned the 4.4mm, that AHA moment popped in my head and I felt so stupid, as always. As it happened when i called my supply rep. which took them over 4 weeks to get the hot air, they just happened to have that tip stocked. $30 later, i went home all grumpy thinking "pff what a joke, this tip isn't some magic device that will get ant leg sized resistors onto a board..." I just put in a 9.3k resistor and a 0.01uf capacitor in a few minutes. Happy am I that a person like you exists to help out the world, for even one person helped, the world can benefit in ways we don't know. Now I can back to troubleshooting a board that has been driving me nuts.

I know a lot about electronics, but working at this scale has never been something I even considered.... what you do is amazing. BTW... Looking at your old solder roll, I can tell you that it's 63/37, (63% tin, 37% lead) as compared to cheaper 60/40 solder... 63/37 goes directly from solid to liquid and back again, while the 60/40 goes through a phase where it is a "paste" before actually becoming liquid which can cause issues.

18:00 IIRC, the core use of analog multimeters probably wouldn't help in your line of work. Analog gauges can help show "trends" of voltage swings because you can watch the velocity (and change of velocity) of the needle. The way you can tell an (analog) speedometer is changing, the faster your car is accelerating, but if you had a digital "clock readout" of your car's speed, it's actually pretty hard to quickly, accurately read the measurement--and much harder to notice how quickly that measurement is changing. Compare an needle moving at X degrees per second, verses 24.6 to 37.2 (or is that 2 and 8? or a 6? or a 3?). You can also read a dial out of the peripheral of your eyes, but reading symbols (numbers) is comparatively a much more "Hands on", focused task. It's much faster to read a position in your peripheral, than to decode numbers.

I own roughly $4,000 in tools total, spanning across a few specialties: More than some, but less than many professionals. Yet I've performed over $100,000 worth of work with these tools in 3-1/2 years. I don't run a business, but I completely agree with "tools paying for themselves." Because that wasn't $100k+ I earned, it was $96k+ I SAVED. The most direct anecdotal example I have is my sewer jetter: It cost me $800, and I was very hesitant to buy everything. But then I went and got a quote from a plumber for the concrete in the building drain: $12,000... So I bought the jetter (really multiple things I strung together), bought some chemicals for it for another $20, and jetted the pipe for about 10 hours of work. Every clog since has been: Remove pipe, stick hose inside, turn on generator, pull trigger, wait 15 seconds, put tools away because any "normal" clog is practically vaporized. Some tools I cheap out on, some I regret doing so, others I don't. I just shop for what my needs are. 10 hours to clear a concrete plug seems like a lot, but I'd hope I don't have to do that many times in my life. So I bought what I believed could just barely perform the most laborious task I'd ever ask of it, that would cut through more common tasks like butter. And I saved an absolute ton of money on those $800 I spent. And don't even get me started on cars.. I'd have had to buy 5 cars by now, but I'm still rebuilding an old rust bucket that's only 10 years younger than myself that was headed to salvage when I bought it for $200. I've probably saved more money on cars than anything, and houses second.

The Fluke is a nice meter and I own a couple of handheld ones. They are handy e.g. when working on cars or household wiring. I think in your tool chain it is a weak link. A proper benchtop multimeter is something you might consider to invest in. E.g. I love my used Keithley 2000 (Ebay around 350$). It measures much faster than I can actually read. It is significantly faster than I can move my eyes from the tips to the display. Speed isn’t everything. It also provides 6 ½ digits. You are describing the process of inserting voltage into a board with your HP power supply. Assuming you do so you want to measure where the voltage drops. So you measure along the line where until the voltage doesn’t drop anymore. With 6 ½ digits you can use lower amperage as you can measure minuscule nuances of voltage drops and hence avoid further damages to the board.
@Sqeezerful8 жыл бұрын
I don’t want to make this a multimeter discussion, but I have to disagree a bit: Yes there are some desktop mustimeters that are just handhelds in disguise. I wasn’t referring to the group of Voltcrafts and UNI-Ts. Desktop MM have a different purposes than handhelds, e.g. apart from the obvious ad-hoc measurements - integration in a larger test setup/production setup (GPIB) is a common use case and you can get more precision. See Keithley 2001, 2002. When measuring a short in a voltage rail you are looking at something that looks like a ladder in which one of the rungs has a very low resistance. By measuring the voltage drop from the source or power supply towards the short usually results in minor voltage drops in 10^-4..10^-5V range. To asses that with some confidence you need some digits in your MM and accurate precision. My beloved handheld Fluke 87 just isn’t up to the task. My Fluke 8840a is a good indicator and I take the Keighley to confirm the findings. I used some old Schlumberger 7150 Plus for that job years ago, apart from the 50$ price tag, they are sluggish and feel outdated nowadays so I didn’t suggest them. Yes there are other ways to trace a short - you can use a milliohm meter or even an LCR narrow down the search. But e.g. a milliohm meter with a low test voltage, and low currents is again a more expensive piece of test gear.

Your model scope might not have this feature, but the one I use (Rigol 1054Z) has a "trigger" option that lets you take a snapshot of the desired waveform when the voltage hits the selected level.

Hi. I recommend after the alcohol to be safer (than heat or baking, coz' like food, it might not be evenly "baked" and reheating things like food, destroys things molecularly) to put the board in a static bag filled with good silica gels (which you can rejuvenate by heating and evaporating every 6 months they say) to get rid of moisture further.

Some cheapo dmm has diode test in the 200ohm scale (no autoranging). This cheap one are fast when measuring resistance, because no autoranging. also, 200 ohm is the lowest range and where the current used for testing is bigger, so anything that needs to charge (capacitors etc) will charge "fast" and give a faster final value. Perhaps that is way diode mode is faster for you. I got a cheap auto range meter and it is insane slow, since takes it seconds to guess the range and then do the actual measurement, but we have a good HP dmm at work, and is almost that slow in autoranging. is faster to put it in manual and select. 200 ohms is enough to tell if there is a short, I mean, you are not changing the range too often. In the fluke you can put in manual and select range and fix the dmm to this range. Not sure in the 15. We have a 75b at work and this control is placed on the center of the selector. The 75b, is WAY faster even in autorange. Really is kickass. I regret on buying a cheap dmm for me, and not investing a bit more on a Fluke. I dont use that often, so I cant afford them easily. I bought it because it is true rms. That is very important (to me). In that sense, it performs really fine, even better than 75b which is not true rms. True rms is nice since can measure almost everything that is not pure sine, you will still get a reading even with is a pwm signal at 10Khz where AC mode (pure sine) meters wont give oyu any readout, since they cut on 500hz or so.

Funny thing, I'm looking at buying a quality soldering station, (you Americans pronounce soldering in a strange way, it's sold ering, not sodering!) and always thought that Hakko was a naff brand due to the colour scheme for children!! So I was going Ersa but will now seriously consider Hakko. On analogue, ie, needle meter, multimeters. If you are an 'older' tech like me, analogue meters were as much a part of your life as a soldering iron! In my case they still are as I work on vintage stuff alot. They do have one advantage, to geezers like me. You get familiar with where the meter needle should be on the scale for certain measurements on certain equipment, so you don't actually need to read the value. Similarly, if you're dab testing for continuity etc, you just need to see the needle move to know it's ok. If you're not of that generation though I can see that an analogue meter would be seen as crap! I will always love my Avo 8 though!

I think this is why people are asking all the time instead of just clicking buy-links. They wanna know _why_ you chose them, too, to understand the pro's and cons, and hopefully thus whether or not they're suitable for them. The days of just blindly clicking and buying as instructed are gone, at least for this kind of crowd. We're talking tools and consumables, not ornamental stuff. And these ones are relatively, pretty expensive, at least for those who do not already know enough to make these decisions on their own. That kinda suggests they don't really have a revenue stream from that kind of work yet.

That "key" for the Hakko stations. There's just an LED and an optical sensor in there, and the "key" slides in between them. Big throughole stuff. If you want to never have to f*ck around with the key again, open it up and put a piece of heatshrink over either the sensor or the LED. To get it into "change temp" mode without entering the key, just press and hold the star button.

I'm the same way with temperature control, the specific heat of the chip, the distance of the emitter from the chip, the specific heat of the chip, ambient temperature, there are too many variables to create repeatability. There are far too many variables to quantify without introducing an uncertainty, and tasks this complex are best achieved with judgement and experience, not integrated controls. This is why we will not see autonomous passenger jet airliners, the system is too complex to reduce to a set of known variables. I run through hole, because I am old school. If an SMC breaks I throw it away and buy a new board. But for that through hole work, I run a butane soldering iron that gets hot enough to glow full red at full blast. Dial it back 50%, change your tip size, and your contact time, and she gets it done. Wasting those $15 tips on that lead free solder is getting old though. Once, one corroded out and I kept using it after the plating was gone, and that thing snapped off of there soldering 1/4 inch cable, and when it broke it landed on my right forearm and instantly melted and stuck in my flesh. I had to grab it bare fingered and pull it out of my arm. Damn you lead free solder. My scars bear testament to my story.
@joekahno4 жыл бұрын
If you're doing this commercially, don't screw around, get a good filter. Until then, being broke is no excuse for wrecking your health. For low rent clean air, shop for the best value (size/cost) on a true HEPA replacement filter. Buy the unit it fits. Run a cheap flex hose, (dryer outlet?) from the filter air intake to your work. Cost of the filters is more important than cost of the unit. If they aren't cheap enough you won't replace them when you should.

I'm with you on how temperature doesn't matter much. I solder at 650 or 700 degrees on my weller station so i don't burn anything up or corrode the tips too fast, but on hot air I'm anywhere from 700 for 0402 passives to 900 for tiny MLF 3x3 with thermal pads and vias because with hot air, it's not about the temperature of the air, but the temperature of the part, and the part will tell you when it's hot enough.

I'm having issues making solder flow on first time use tips. I'm using T12 tips which supposedly are Lead-free but over and over I'm having issues trying to tin these tips for the first time. I normally put some colophony flux around the new tip and roll some tin put the iron at max temp and wait for it to melt. But by some reason I can't see solder wetting and flowing properly on the tip, I'm getting pissed. I have to clean with the brass sponge , put some flux on the tip and then tin again .. over and over.. solder doesn't stick on the tip, by the way the tips are good quality. I tried some 900M tips which are pure copper and this doesn't happen.
@pjtruslow6 жыл бұрын
daaudiome weird. If the tips say lead free, that does not mean you can't use leaded solder. I've never had new tips fail to tin if they were new, but if they were corroded, I had to use this special tip tinner, which I think we got from MG chemicals.

Your microscope link goes to an AmScope SM-4TP wich seems like a better scope than the Omano because it fits your discription of what a better scope would be with the zoom from 7 to 45. Also, Amscope sells the WF5X eyepieces that will cut that in half to 3.5 to 22.5 and some cheep (or expensive) 15X for magnification from 10.5 to 67.5. They will probably fit the Omano as well.

Temperature isn't all it's cracked up to be. With low temps you heat up a larger portion of the board/components before you've reach flow. Where as with higher temperature the component you're working on heats up faster than the rest of the board= less heat transferred into the surrounding area.

My Weller was $1400. Hako has a lot of value for the price. I really like Hako! The desoldering thru hole I have is a Hako. My hot airs are Hako and a $30 no name backup one that works fantastically well. The small tube tip works great. Everything I own that I "NEED" to do my job, has a cheap Chinese made backup unit. Some of the cheap stuff works amazingly well, but, for how long? As for solder temp, fuck it! How long will I expose the part to the heat? Do I get a good fast solder joint & not cook the part or the board? Am I cleaning up flux & solder blobs, without damaging anything? YES GREAT WHO CARES WHAT TEMP!
