Very poor SMT work. AVOID
While PCB are okay, SMT is to be avoided. Now did about 5 batches of SMT boards with PCBWay for a total of about 30 boards. Out of these, about 50% did not work out of the box because of misplaced components, reversed polarity, missing components, and unsoldered pin. Those problems are random so it is a pain to fix. Beyond that, all boards exhibit cold joints or bad solder wetting, which makes the board unreliable. In some cases, there is no electrical contact at all, some are unreliable, or sometimes some components can just pop out. This is caused by bad processes, either bad / too old solder paste, wrong reflow temperatures, too much delay before reflowing. Opened dispute, PCBWay ensure the joints are "normal" despite clear cold joints pictures under a microscope, which leads to either they are lying, or either they have no idea about proper solder joints, which is bad either way, proposed a 20$ refund while 600$ project cost and about 500$ in components wasted. Given those boards are unreliable they can only be discarded. --- EDIT, sent pictures and then no replies from PCBWays, how many bad joints pictures do you need? This is just some made-up reply. imgur.com -> L9lpLRm imgur.com -> lW3cpAe
