uxcell Double-Sided Copper Clad Laminate PCB Circuit Board, FR4 100x70mm 3.94x2.76 inch, 1.5mm Thickness DIY Prototyping PCB Board, Name Board, 5pcs

Works well for both heat and UV transfer as well as hand drawn circuits.I would recommend.

Good grade of base epoxy fiber and copper clad. Prints and etches very nicely. Fast shipping.

the boards arrived a little scratched up, most of the scratches were shallow, superficial and didn't effect when I etched the boards, but there were a few deeper ones. they etch well, but make sure to wash them well before printing on them.

Nice boards for my Electronic Hobby.Would buy again.

I attempted deep engraving with my laser engraver, expecting it to completely isolate traces, but the board still conducted electricity in areas that should have been non-conductive. Low-quality copper layers or poor adhesion to the substrate could be a factor here… other similar products have worked flawlessly with this same process…Overall, I’m disappointed with the quality and durability. The product didn’t meet my expectations for either packaging or functionality. Improvements in shipping protection and material quality are necessary for a better customer experience.

i took my chances based on the review i saw, and unfortunately this time i lost. The boards are of a VERY poor quality and have MANY defects. Of the 5 boards, none were free of defects. If i had more time, i would absolutely return these for a refund. I will be asking amazon support for at least a partial refund as these are just so bad i was only able to finish my project by breaking apart the circuit into several smaller circuits, using the "best parts" of these boards, then soldering the pieces together... Buyer beware! these boards are truly awful.

I just got these and opened them. I took photos of one side of two different boards. (They're two-sided copper.) I would not use these to make PCBs- they'd cause problems. But I'm not using these for that (and I stopped making PCBs for myself a few decades ago). I'm just using them for some shielding and, one for ESD protection on my bench. The third phot shows some of what was on the paper towel after I used Scotch-brite, then wiped both sides with acetone. Hmmm...not great.I've seen similar complaints about other brands of cheap boards on Amazon. PCBs are so inexpensive now, it's not really worth making them yourself anyway (unless you are trying to learn).

Mild damage. But overall, good for the price
