Good morning Nick,<br>

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.<br>
<br>
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).<br>
<br>
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. <br>
<br>
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. <br>
<br>
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.<br>
<br>
Good luck with your project.<br>
<br>
Regards,<br>
<br>

<div dir="ltr">Hi all,
<div><br>
</div>
<div>I'm making some modifications to a circuit board from an
old video game controller. Originally I was going to scrape
the solder mask off certain spots so I can attach the wires I
need. When I attempted this, I wasn't able to get a good join
(without much force the joint broke off the board).</div>
<div><br>
</div>
<div>So, now I'm thinking to get a piece of prototyping board
with through holes. I need roughly 12cm x 4cm pieces. I'm
thinking to buy a larger piece and cut multiple 12x4 pieces.</div>
<div><br>
</div>
<div>Any suggestions for places to buy these? Amazon has a lot
of options and Mouser has a lot of options. I'm not really
sure what the differences are.</div>
<div><br>
</div>
<div>Any help would be greatly appreciated!</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Nick</div>
