These pcbs were ordered to build discrete-part replacements for Sanken STK-0050 Darlington audio output modules, as used in older Pioneer stereo receivers. I submitted CAM files of good provenance, with comments that I hoped would address any concern (holes outside board outline). 36.2mm * 62.2mm ,Thickness:1.6 mm, 2 Layers, Finished Copper:1 oz Cu I was contacted promptly by Amaris, with an inquiry about whether mechanical clearance holes inside the board outline could be un-plated. After receiving my response, the order was filled and shipped very quickly. Even with the slowest/lowest cost shipping option, China Post, the order was delivered to my address in Canada within 35 days. The product I received appears to be of excellent quality, exactly as specified and expected. The value for price is excellent. I have several pending projects that will need pcbs, and I will be ordering them from PCBWay. For price, quality, attention to detail, professional communication, and prompt shipping, I am satisfied and impressed.
