Kit projects AGC install


Kelly Mabry
 

Does anybody have any suggestions for how to do the drop in portion of this kit-projects AGC board.. switch is wired up..mounted on front panel.  I am dreading this due to a dremel tool with only high speed rpms and shaky hands.

Would an exacto or a box cutter be acceptable to scrape away the top of the trace to get to copper?

It seems this install goes in one general spot with very little room to spare. I will look at it more tomorrow and snap a picture or two to provide more Information about my concerns.
Any advice welcomed...

position the board and mark with a sharpie the spots where You need to expose copper below, then use a small flathead screwdriver, or anything small, flat and hard to scrape away the coating and expose the copper.. You don't need to use much force, just take Your time and get a good strip exposed at each spot. You don't want a sharp point for this, just a hard object. Then tin both the AGC board and the exposed spots with solder, and the rest should just be a matter of adding enough solder to make a good bond, once You have the AGC board aligned in place. Maybe use some masking tape to hold it in place if You have big fingers..

I agree that a dremel is not the way to go. they are the Uzi of power tools. look cute, but are utterly useless, unless you like damaging Your fingers and making lots of noise.

Thanks for the response!
Kelly I just responded to your email, again apologies for the delay.
I have paraphrased below.

The only addition I have as of moment is that the castellations that you are soldering to the trace have copper on the bottom. Apply as little heat as needed, they make a solid joint easily. The solder should just start to come up the cup. It does not need to reach the top of the board. 
A decent example is in this picture

Just so it doesn't get missed, don't forget that the one trace needs to get cut open.

Well, Playthatbeat Mrdj...that quote defines my experience when adapting my front panel board for a keyer.

"I agree that a dremel is not the way to go. they are the Uzi of power tools. look cute, but are utterly useless, unless you like damaging Your fingers (and boards) and making lots of noise."


I might just hang that on the wall of my shack...

Hi! No worries on the email thing. I replied to your there, but here in open forum might be a better method of reaching me. Bless you brother.
