I needed a sturdy board for a dense circuit layout and this 1.6mm FR4 material didn't flex at all during soldering. The tinned pads are a nice touch, making each joint quick and clean.

The 1mm holes are perfectly aligned for IC pins, and the FR4 board feels rock solid when I’m soldering. I’ve already built two circuits on this 60x40 size and the tinned pads make each joint quick and clean.

It’s the exact thickness I hoped for, that stiff FR4 material makes soldering feel solid and secure without any flex. The 60x40 size is perfect for cramming in a small project, and those tinned pads take solder beautifully on both sides.
