EEVblog 1650 - Sequre HT-140 SMD Desoldering Tweezers REVIEW

[@KeritechElectronics]

Nice tweezers, I'd love a pair for my service work. Now I wonder how long will it take until Fnirsi launch one. I hate the grub screw mount on the tips, it's a destroyer for sure. If they made a better mount, like a collet or something, the tips wouldn't get deformed and you could share them with a soldering station no problem. The DC barrel jack is like nothing I've seen before, I could almost trust it with life, universe and everything.

[@itguru4989]

It is not necessary to tighten the screws so strongly - the soldering tips center themselves accurately enough. The tips lock in exactly the same way as any soldering iron with JBC type soldering tips. These screws are for more precise alignment of the tips

[@daveturner5305]

@@itguru4989 True it's not necessary but over tightening is almost guaranteed - just to be sure.

[@itguru4989]

@@daveturner5305 I agree. That's the price to pay for small size and not wobbling construction

[@davadoff]

That DC barrel jack first showed up in the TS100, and now other USB irons use it too.

[@s_s-g4d]

thermal capacity wise it may be not so good, but thermal TRANSFER wise it seems to be great! otherwise it wouldn't have dropped down to 50-60 degrees on the thermocouple inside the tips and would have shown higher temperatures. in other words, there seems to be good thermal coupling between the heater element and the outer surface of the tips.

[@decee1157]

I am SO impressed by this! Those tips seems really good since it respond so quickly to temperature changes.

[@Lagittaja]

Max current is 5A so if you had adjusted the current limit in settings it probably would've reached it when you used the DC barrel jack. Very nice looking tweezers all together. Considering how well they work, I'm tempted to try their C245 or C210 USB-C irons.

[@rickoneill4343]

What a beauty. So good to see all these affordable innovations with standard power delivery.

[@emmettturner9452]

Sequre S99 comes with that same 65W PSU. They actually suggest using a Lenovo Legion C135 for 150W, 2.5Ω tips (included one is 75W, 5.5Ω). Powering two smaller tips could probably use the upgrade. I just finished building a portable battery stand for my Sequre S99 today and I’m pretty proud of it. Got a Power Wheels adapter for DeWALT batteries and mounted a metal plate with a binder clip attached. Then I threaded a spring door stop into the binder clip and cut the excess so the iron tip would protrude. Connected the included XT60 to USB-C cable and it totally works!

[@shaunmorrissey7313]

I have the S99, cracking little iron

[@emmettturner9452]

Definitely, but I’m off to a rocky start with mine. The accelerometer didn’t work and they sent me the defective V1.4 PCB over two months after they supposedly corrected the issue in shipping units (not for American Amazon orders, it seems). I couldn’t even claim the compensatory free iron tip since they explicitly exclude orders after April 23rd. I had to wait on a replacement V1.5 PCB for the accelerometer issue so it didn’t make sense to do the required capacitor fix for V1.3/1.4 PCBs. Hopefully they’ve got these issues behind them so that the iron can shine! It deserves more attention. Driving 150W JBC tips is a huge difference from the MiniWare TS-80/100/101 irons.

[@CrypticWritings89]

This thing is awesome, I'm really impressed. Excellent build quality, good thermal performance, comes with an actual useful stand, meets its claimed specs and is not too expensive. Checked pretty much all the boxes afaik. After the massive disappointment with iFixit portable soldering iron, I'm glad Dave reviewed this fella.

[@novotd443]

I'm a mostly self taught hobbyist. You blew my mind with the sponge water expansion. I always thought that they are damn useless XD

I've been on the hunt for a good pair of hot tweezers. I need to try these

[@Stefan_Payne]

One thing I wish you do was to desolder some Electrolytic SMD Caps... Those seems to be the biggest pain in the behind and something some of us might want to change (old consoles from the 90s and 00s for example)

[@peterlarkin762]

Got a Sequre SI012 2 years ago. It's so good that I ended up using it for everything. Quite a bit of mileage on it now. I did not expect the level of quality for the price. Plus, the sequre tips are nearly as good as the JCB tips, and priced very well.

[@QsTechService1]

wow, very impressive for the price. If this device was out, I probably would’ve purchased it if I did not pick up the JBC tweezers PA120 .. this device would probably perform even better with JBC tips would be cool to do a video comparing this device against the JBC tweezers

[@unintendedperson]

thanks dave to show me that the small c210 tips can melt the solder wire beautifully in the mass ground plane board

[@Audio_Simon]

I use a tip big enough to contact both pads across the side of an SMD part from 0805 down to 0402. Works for soldering and de-soldering. Seems like these are for larger parts like those diodes.

[@nonsuch]

Great tool. It makes light work of those small SMDs for sure. Good price too.

[@johnnodge4327]

If you change enough SMDs, hot air is faster. When I work for Sony, we changed all sorts of devices with nothing but hot air.

[@treborrrrr]

@@johnnodge4327 With tweezers you don't to worry about accidentally blowing other random parts off the board though. 2-3 seconds to heat up the iron, another 2 seconds to pluck the part off seems plenty fast for me. If you need to remove a bunch of differently sized parts though (as in different amount of pins for example), than that's a different story of course since swapping the tips out is going to take a bit of effort.

[@rozwell69]

There should be a "TempStep" option under HT so you can increment/decrement the temperature by this value and use like 10°C step.

[@daveturner5305]

I already have soldering/rework stations giving me hot air, soldering irons, tweezers and desoldering 'heads' it can be a right nuisance swapping between said functions. This device looks to be a neat addition to the bench.

[@MrPnew1]

1:45 so it's definitely spongeworthy Dave 🤣 I wonder what it's like with something like a Macbook board that has ~ 15 layers and large GND planes?

[@notsonominal]

Oh, I built me a Weller clone using RTW tips from Weller as at the time all the cheaper alternatives were massive and wildly inaccurate. This would have been a possible contender, but by the looks of it the Weller is still the smaller more accurate alternative.

[@crazyphil33]

Damn it Dave! Now that’s another AliExpress gadget I’ve just gotta have! lol 🤪👍

[@Al_Lergic]

[@mediocreman2]

What's a type C accessory? Does that mean it's not as good as a type A accessory?

[@grahamnichols1416]

Two low-cost pencil irons from Amazon @ $20 total. Job done.

[@pilotsmoe]

You should check out the FNIRSI HS-02A (JBC c245 tips) or the FNIRSI HS-02B (c210 tips).

[@tunderbird123]

Mine is on the way...I really need it for my led sceen repair job

[@danman32]

Buy a PD adapter and high quality USB PD cable, get desolder tweezers for nearly free

[@chrisridesbicycles]

Could you do a comparison of cheap and expensive soldering gear? I winder how disappointed I would be with these USB stuff in comparison to all the JBCs at work.

[@danedwards_ee]

Neat, I think I'll pick one of these for work.

[@mrDarktrooper]

I would like to see the tips held in with a nut and wedge collar instead of the grub screws

[@gamerpaddy]

looks nice! i got one of those ksger with a external control box, but the handpiece is horrible.. nothing lines up, tips are huge and cant be swapped gotta wait until aliexpress allows shipping for those over here

[@AlessandroAllegretti]

An hard test would be desoldering SMD electrolitic capacitor. It is always difficoult for me

[@davadoff]

I was wondering how ESD safe is DC based soldering iron pulsing on & off? Especially with C245 (8-10A). Does it not induce voltages around the tip like wireless power transfer? Opinions? 13:50 I noticed it shorts out or something happens & the mic pics it up, like static? Do you hear it? Or is it a coincidence?

[@EEVblog]

RFI mic pickup when the heavy current switching started up. Not uncommon.

[@1kreature]

There was a "temp step" in the menu so the 50c steps can be changed.

[@markybyeah]

He’s gonna use it in the lab, twice, its really neat he’s going to use that in the lab… Good old editing fail 😂

[@policyprogrammer]

Do people generally expect to reuse two-pin SMD parts that they remove this way? Because if they're like me and think rescuing a $0.02 passive is silly, the technique of just putting a big blob of solder on the part and flicking it away with a conventional iron works pretty well and is free.

[@asm2750]

For boards that are no longer made like vintage computers and game consoles using SMD tweezers gives a person piece of mind when recapping.

[@EEVblog]

Very common to remove the part for testing out of circuit, and if it good you might put it back in. But it's also about doing the least damage to the pads.

[@proluxelectronics7419]

Just ordered mine from the big rock candy mountain...😁

[@vadivelanellappan42]

Hateful autofocus, always moves to show your fingers instead of screen. Please, manually focus.

[@TheThomasites]

Looks like you can change the step in the HTT setting.

[@mediocreman2]

So this can only be used for desoldering? They can't be used for soldering?

[@michaelnitschke9872]

Left/Right select would be left or right handed I think 🤔

[@maskedviperus]

[@andre-7423]

[@KarlWhales]

Neat!

[@LawpickingLocksmith]

No shoephone is safe anymore from being repaired?

[@cannesahs]

Has it only 2 wires to a C210? No 3rd wire for esd-safety ground without current carry?

[@LarixusSnydes]

That's actually a very good point. I own two Sequre soldering irons and they both have a mounting screw for a grounding strap. Perhaps this one has that as well.

[@JAKOB1977]

Stay on the course 17:08 and make the indicated shootout for LCR tweezers

[@Slugsie1]

LR Select, surely that's for left handed/right handed users?

[@itguru4989]

There is another setting for left handed/right handed users - screen rotation by 180 degrees. This option exists in almost all Sequre products. LR select - You can use and control both tips when using HT140 as tweezers or use only one - only right or only left tip if You need to use HT140 as soldering iron

[@Roobotics]

Not a fan of the grub-screws at all.. That would have been an absolute ideal place for implementing a split-ring type bolt tensioner. Same thing most mini ball-joints use for holding onto the ball-mount, where a tapering screw forces leaves to squeeze in closer with each turn. Passing on this one, poor mechanical engineering on a very crucial spot, looks great otherwise, but that approach is so 'meh'

[@A13tech]

There is a learnig curve how to use tweezers. Even if you have JBC (as we have) you might think that it is a piece of crap. No, you need to know how to use it and when to use it and what is the use-case.

[@alch3myau]

Ryobi One+ soldering iron/station review next week? AEG handheld pocket butanes the week after?

Now imagine a LCR meter with spring loaded tweezers like that. Not the 💩on aliexpress.

I never really understood what the sponge is for.

[@MSP_TechLab]

Very nice product. However, realistically, who would use them in the field. IMHO such instrument is for lab, service centers etc.

[@stoyantsalev3109]

You'd be surprised of the stuff that comes up in the said field... Also, the definition of "field" varies widely across industries/sectors. My point is this thing is much less niche than it may seem.

[@MSP_TechLab]

@stoyantsalev3109 yes, I do agree that my understanding of "field" is limited only to my own experience. But even when I maintained 70s era telecom equipment which was full of through hole components, I have never had a necessity to replace even transistor in place. Just replace a board, get broken unit to lab and repair it there (usually we had dedicated people in the lab for that, but it's another story). That is why I doubt that now, someone would need to repair something like 0805 in place.

[@johnf4085]

Oh my god, its "Secure". Not "Seh-Qu-R-Ay" like I first thought. Im dumb.

That's 80% of the voltage rating. They're not tantalum caps. They will be fine when used with a regulated power supply.

[@yoppindia]

They forgot the kitchen sink, so disappointing.

[@arekx]

Aren't these tips JBC style and thus you could use original JBC tips?

[@EEVblog]

Yes, that's the idea.

[@cypair]

You can see at "Wielki Elektronik Shorts" channel that he was using on original JBC tips :)

[@cannesahs]

Atleast Sequre S60P (C210 tips) requires you to recalibrate temperature for original jbc tips. They use different metal pair in thermocouple. After that use only JBC tips and all good

[@M.E63]

Yh they are c210 tips so JBC ones will work
