YUNGUI 15 X 20CM PCB Protoboard,2 Pieces DIY Prototype board Soldering and Electronic Printed Circuit Board

Looks like a great value for perfboard. I wish these were cheaper, but the other products that I’ve bought that are cheaper smelly horribly and are quite flimsy. These seem to be sturdy and I suspect will tolerate some repositioning (read: desoldering) of components. They also do not smell at all.Would buy again!

None

My I.cs lineup was perfect and the bus made my layout ideal

but you better get everything right the first time or the circuit traces start breaking down.

The pads and traces come off the board too easily. Even mechanically wiggling a soldered component a small amount causes a pad to rip away from the board. Have had several failures of previously working circuits due to this.Must complete a solder joint quickly otherwise the pad comes off.So tired of this Chinese junk that can’t handle its most fundamental function. Not worth the wasted time. Not recommended.

These are solid.

Can fit parts for my protoype into thru holes Unless all your parts have extremely tiny pins (resistor, connectors, etc), won't work.Standard headers and breadboard pins will fit, though.

I didn't notice that the holes are only plated on one side (didn't look at all the photos). Not a big deal for what I'm doing, just be sure you notice.
