10-Pack Double-Sided Copper Clad Laminate PCB Circuit Boards - Perfect For DIY Prototyping! Review

well they arrived and now will be testing them by milling the circuit onto them. They appeared relativity defective free apart from the one finger print smudge on one of them and the odd abrasion on the other, this didn't remove much material it appears like a small sand paper rub the copper is just shiny there.dimensionsmore importantly however the boards are not 100mm x 70mm they are slightly under that size clocking in at 98/99mm x 69mm and some haven't been cut squared, but this can easily…

These boards were cut with a shear and the copper comes pre-delaminated from the cheap board filler. Not suitable for advanced circuit designs! Junk.

Great product, the etching process is very easy with these boards, unlike others that seem to take forever to get the unwanted copper off. Great product definitely recommend it.

The plates I received had many nicks and dings in the plate. If your working with SMD, you may have a hard time. Semiconductor Products!

Used these on my small cnc and milled the circuits without problems. However one board had very strange shorts. I ended up sanding a bevel on the corner to find that one board was a 5 layer board! Explain that. How could you ever use a premade 5 layer board?

Had two boards come in unusable due to copper being completely scratched threw. The rest of the boards came scratched up but appear usable. Bought these to cnc mill and had to use a z-probe height map due to them being warped.

Very thin copper cladding. Also some scratches that were deep enough to cause issues when doing heat transfer. Thanks for attention!

Cheep, rough, good for some deadbug projects, but some boards are unusable due to corrosion, contamination, or copper scraped/worn off
