Re: Two little circuit boards for my Bitx40 txcvrs

Or crush the SMD with clippers, then remove each half individually with a small solder tip.

When you use a hot air gun for soldering or removing parts you stand the risk of causing other close parts to move around. I just use my soldering iron and rotate the heat from one end of a component to the other and finally it becomes hot enough to move around so just flip it off the pads with the iron tip and the part will be detached. I've never lifted a pad or damaged any board using this method so far. Good Luck,,, Dale

Any ideas for how to remove the tiny resistors R1 and R2 (about 1mm in length and .5mm wide) so that I can use potentiometers instead?  

Hello Mike,

A Hot-Air Gun seems to be the recommended way to remove SMDs from a PCB.
But please be careful. I recently bought one, and I have toasted a couple
of "practice PCBs" while learning how to use it. I still have some more
practice to do before I feel comfortable using it.
