Chanzon 10 Pcs Single Sided Copper Clad Laminate PCB (7x10 cm 4x2.7 inch) Copper Plated Universal Circuit Prototype Board for Etching DIY Pcbs Kit

Figured I’d leave a review since there were quite a few bad reviews talking about the copper surface being scratched up. Indeed these come stacked on each other in a bag, so I can see how that would happen, but the boards I got are all in good shape. At less than $1 per board these will work great for DIY projects. The sizes all range a bit and the corners aren’t perfectly square, so YMMV for fixturing etc.

The copper clad boards were received in clean condition, and appear to be of good quality.Overall thickness is 1.37 mm, only a single side, copper clad, and the substrate appears to be some kind of phenolic.Over the years of my working commercially, I always expected to see fiberglass substrate; this phenolic takes me back to the 1960s :-)I will be using this for simple audio frequency work, so the phenolic dielectric is not going to be a problem.

Very thin copper cladding and copper delaminated easily. Heat wasn't a problem but drilling holes in copper pads, milling the foil pattern, and even straightening a pin caused delaminations. If etching with ferric chloride, you might be okay but I couldn't engrave these at all.

If you build a lot of electronic hobby circuits this is the way to go. Good quality and price.

Nice uniform and expertly manufactured copper plates to be used for an electrical experiment. They were the right thing for the right price

I made some small boards using thermal toner transfer and noticed when cleaning the surface with a ScotchBrite pad, that it is not glass-flat. They were very clean when they arrived and had no scratches But there is some slight texture to the surface that you see when first start cleaning. After scrubbing in all directions it seemed fine. I got pretty good adhesion and etching with a mix of line widths down to .020/.015” lines and spaces. I always make more than I need and about 70% of the boards etched cleanly.

I'll definitely buy from these people again.Great product.
