[TriEmbed] prototyping boards with through holes

Good morning Nick,


These may help you out:

Your solder joint pulling off the board could be an issue with 
insufficient heat. If there is a lot of copper, you need a large heat 
mass to heat the copper and solder to create a good solder joint. Also, 
after you clean off the solder mask, polish the copper just a bit, and 
then apply rosin flux and pre-tin the solder connection points before 
soldering the wires.

If you can make use of an existing connection to the copper trace of 
choice, you'll have an easier time (no solder mask removal, no tinning 
required).

Cutting FR-4 is easy with sheet metal tools, but it is tough on material 
(glass strands imbedded in a polyester resin). I've used a metal blade 
in a jig saw, tin snips, a sheet metal shear, dremel tools, and my CNC 
router. You can also scribe score lines and snap with the scribe line on 
a hard surface ... a piece of steel angle can be a good scribing AND 
snapping guide. Make several passes with a sharp blade before snapping.

If you have access to a tile wet saw, that would be a quick and easy 
tool to use for cutting large stuff down to size, but the kerf is a bit 
large. Water keeps the dust under control.

The tan colored pc board material is paper phenolic ... compressed paper 
impregnated with a phenolic resin. This material is not as hard on 
tools, but is more brittle and may shatter in a shear.

Good luck with your project.

Regards,

Rick
