Chanzon 10 Pcs Single Sided Copper Clad PCB 7x10cm Circuit Prototype Board

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.

I bought these boards for my DIY PCB projects, and I'm happy with them. The copper surface was clean, the boards arrived flat, and they were easy to cut to the size I needed. They've worked well for prototyping so far, and I'd buy them again.

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.

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.

These are not FR4 substrate. They are the same brown phenolic consumer electronics boards you find in a cheap CD player. They were of good quality if you are OK with phenolic boards, but not what is advertised or expected.

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.

Solid quality copper clad boards. Laminate seems to hold up very well (doing laser printer/hot-iron method) and never experienced any laminate separation (even when I accidentally left the iron sitting on the board for 10-15 minutes). Will be purchasing again. If you're doing at-home etching, I'm confident in saying I think you'll be perfectly happy/satisfied with these. Cheers!

Kupferbeschichtung löst sich teilweise ab beim Löten.

Custom PCB. Very fragile traces due to thin foil layer.

Ich fertige Platinen mit meiner Fräse und es kam schon ein paar mal vor, dass sich die Kupferbeschichtung abgelöst hat. Insbesondere bei diesem Verfahren ist das ein echter Nachteil.
