لوحة تجارب PCB عالمية من الألياف الزجاجية ذات وجهين (3 × 7)

The 1.0mm holes are perfectly sized for jumper wires on my bench projects. I especially appreciate the standard 2.54mm pitch that matches my breadboard layout perfectly.

I’ve been using this 3x7 glass fiber board for a small amplifier project, and the 2.54mm pitch makes component placement a breeze. The 1.0mm holes are just the right size for standard leads, and the board feels sturdy enough to handle soldering without flexing.

The 1mm holes on this board fit standard component leads perfectly, making my soldering much cleaner than on cheap phenolic boards. It's rigid enough to handle multiple reworks without the pads lifting.
