Another great repair Peter. Two suggestions. One is to use Kapton tape to help shield surrounding components when using a hot air hand piece. The second is to use a SMD desoldering alloy. I did a video the other week where I demonstrated how to use it. Great for use in areas where hot air reflow isn't practical.
@PapasDino7 жыл бұрын
Kapton tape is great stuff - In those really tight spots where a soldering iron is needed I use a Weller WM-120 miniature iron which has a tiny, very sharp tip that lets you get in between stuff minimizing the chance of damaging adjoining components. You also reminded me that I need to make up another TMP connector dongle with a female connector to be able to connect downstream in a circuit. Great job as usual Peter, thanks! 73 - Dino KL0S

Nice video Peter, I like that you go into details, used your signal generator to simulate estimated input to the output board and isolated 'blocks' of the signal path to identify the trouble location. Though you wetted my curiosity with what the 'normal' output of the low level amp would be once it was replaced. It would have been nice to see if it in fact was +3DBm or what it would be once connected to the output board. Thanks again for your time making these videos.

To remove a definitely faulty SOIC component without heating and dislodging nearby components, cut each pin close to the case with a small thin sharp sidecutter, then remove the pin stubs from the pads individually with a soldering iron and solder-sucker or solder wick. It is important to use a thin sharp sidecutter so that the pins do not snap sideways when cutting, which can lift the pads from the PCB if the pad traces are thin (in this case the traces are as thick as the pads so it is not as much of an issue). You can also use a very sharp knife to cut each pin, though that requires a bit more skill to avoid slipping and damaging the board. Solder-wick the pads, clean and then apply flux so that there is a flat surface to lay the new component onto. Then clean off the flux.

Hi Peter. That diode with the orientation problem. Rewind your video a few minutes and take a look at the placement. If I do a repair, like you, I always video what I do, just in case I lose track of a component or or its placement on the pcb. I always enjoy the professional way you go about finding a problem. I too have an IC-7100, IC-7300 FT-2000 and an FT-817. Just one thought that you might do for us viewers: Before or during your videos, could you take a few moments to highlight common problems you have found with the radio you are working on? It helps us collect the components that are known to commonly fail for a possible future repair we might have to do to keep in our personal stock. Regards Tony - G6YPK

Great work Peter! This is the proof of being methodical always pays. A quick question; I want to build a 1KW HF lineer amplifier for my station, I found a lot of schematics on the internet but I don't know about their quality. Since these kinds of transistors are very expensive, I don't have the budget to experiment and make mistakes. Can you advice me a circuit that you know works well, and fairly easy to build with easy to find parts? I know that tube amps are much easier to build and they are tougher, but I have no experience with tubes and they are not very easy to find in my country, so it seems I'm stuck with transistors :-) 99% of the time I work in 40 and 20 meters, so it really doesn't need to include other bands. Many thanks! TA2AWX

I was thinking exactly the same thing being a new 7100 owner myself. Seeing a lot of videos repairing what look like new devices is a little concerning. I also noticed also that MMIC chip is marked obsolete in a lot of the online stores and seems hard to get. Great video though as always!

@psionl05 жыл бұрын
My maths must be off. According to the specs, the current drain of the BGA2709 is Is= 23.5 mA. Across a 100 ohm resistor, that equates to a voltage drop of 2.35 volts. Therefore the voltage at the chip should be Vs= 5 - 2.35 = 2.65 V.

just use a sharp blade to cut the terminals of the SMD IC, lift it from the board, and a 20 watt Weller to clean the remaining terminals from the board. Use the same Weller to solder in the new part. It's a lot easier, and cleaner procedure.

Hi Pop, I would not recommend this method as with the mechanical stress you can easily destroy pads...
@tlrptg7 жыл бұрын
no, don't worry about destroying the pads, you have to cut the leads exactly near the IC's body. I've tested this method on all kind of SMD IC's, even on those 64 pin Kenwood PLL ICs. Works perfectly.
