Comments On "Soldering"

I put this thread up in the event anyone had any comments on the thread, as opposed to mixing it into the tutorial.

The soldering creams are a delight to use in flat-packs, and SMDs. They bear micro-solder balls, that melt instantaneously. So you lay down your microchip and position it under a microscope, add some liquid flux to the Printed circuit pads to act as a temporary adhesive for the chips, then lay down the cream on top of the leads or edges of the leads and touch with your pencil tip. It takes practice to get a good filet on each connection. That's what I used in military applications. The Military instruction manual course was a specialty course for the military electronics technicians. I believe it was call M3. You can download it from many sources. It is a very good illustrated booklet.

We used Pace products for circuit cards. Here is a manual with a good glossary on soldering.
