This board was ENIG (gold) and the re-do was still in gold, even though I told them HASL would be OK (I was just curious how their ENIG finish looked). I also learned that all pads have to have a circuit attached, or they won't through-hole plate (what happened to the lower heat sink mount), something to keep in mind with this processor. The result was an error in a manufacturing file on their end, so they re-did the board at their expense. Their customer service got right back to me via email and had an in-house engineer look into it. Well I'm happy to say these folks passed the test. The true test is how a company deals with it when a problem comes up. The yellow circle isn't a mistake, those are through-hole plated slots that pcbway processed perfectly! Mistakes can always happen, especially with the super-short timeframe these folks build the board in. The pads for the large heatsink were missing (one through-hole plated but the other didn't) and half the large electrolytic pads mysteriously shrunk. The third board (a 2 layer but large - 148mm by 143mm) is the most interesting because they did make a fabrication mistake, as the last two photos show (the red circles). It would have had text on the bottom for all the SMD parts if I didn't screw up one library part on my end and put the text on the top by mistake. This design has parts on both sides of the board. Pcbway got it right! I've built up a couple of the boards now and they work perfectly. The next board was a lot more involved with 4 layers. If they screwed up a board with one trace on it, that would have been the end. Lol, I figured this was a good first test board. The hole is to allow heat from parts on a board below to make it up to the top of the case and out some rear panel vents. Pcbway processed the big milled-out hole in the center correctly. The first board is just a top-slot carrier board for another PC board, so (almost) no circuitry. Since then I've run the 3 boards in the photos below. The pcbway price couldn't be beat, the processing time was incredible (short!) and they ship via DHL express for just $25 (I've been paying $35-$45 at Seeed Studio). I've been using Seeed Studio in China for the last couple of years with good results, but the prices have been creeping up, especially with the shipping. I first found the company a few months ago via, a board comparison service that Mark Johnson had linked to in another thread. I was going to start a thread about these folks after having a few good ordering experiences, but I just found this one via search.ĭisclaimer: I'm not affiliated with pcbway in any way, just a happy customer at the moment.
