We haven't actually put that many components on the board yet, but in this video we will. I'm speeding up the video to get more components into this step. There are a lot of components on this board. With that said, I was actually able to get the board populated in one night. In terms of the video, however, it seems longer.
Step 22: Driver Part 3 - More amazing video clips are a click away Today, all of the components up to the large capacitors get installed. I also move the resistor network to the correct position from RN4 to RN5. It was a painful alteration. My usual technique removing a multi lead device yeilded a leadless component. Actually, I was able to save one lead. My method of removing a multilead componend is to first remove all of the solder with a wick. Even though this is done, there is still a bit of solder on the leads to render the component unmovable. I then use the soldering iron on its side and push all of the leads towards the PCB. It usually works, but this time it didn't. Instead, I got a little impatient and broke all but one of the leads. To mend the problem, I add solder to the top side of the PCB (silkscreen side) into each hole for the broken leads. Then I insert the resistor network with the single lead and re-heat the solder to create a solder bridge onto the broken leads. I turn the board over to add solder to the trace to complete the contact. | |
