OSH Park Solder Mask Quality


If you are into hardware projects at all, you have probably used OSH Park by now to fabricate some PCBs. They are very cheap, pretty speedy, and fabricate what I consider to be excellent quality boards for hobby use. However, it seems the formula for the solder mask has changed. In the image above, the PCB on the right has the older, matte textured formula. The PCB on the left has the newer, shiny formula. The old formula seems to be higher quality, and just generally looks smoother and more consistent. The shiny formula flaked just a bit in some small areas after soldering. Like most things, the reason was probably cost. Just curious if anyone else has any clue what's going on.

Hello There

Hello there, my name is Wes and I have Too Many Projects. I have wide-ranging interests including software development, working with Linux, and doing some hardware experimentation and design as well. This page will hopefully serve as a good place to coalesce all my experiments into something readable and tangible.
