I do have a favourite manufacturer for pcbs but sometimes its smart to check out the other fabs. I’ll test some manufacturers and write short reviews about them – this time: Seeed Studio Fusion – https://www.seeedstudio.com/fusion_pcb.html
I plan to do something with Nixies in the future but wanted to use a modern driver. After a bit of searching I found this awesome project: https://github.com/dekuNukem/exixe
Damn impressive and even open source! Since pictures are worth a thousand words have a look for the driver pcbs:
The edge cuts are clean, no frizzing at all. That’s pretty nice. Unfortunatly Seed puts a production code on the silkcreen. Meh, I really don’t like that.
Looking very closely you’re able to spot the marks of the e-test probes. Pretty impressive, I’ve never seen them before. I wasn’t even sure if my fab does this test.
Following up are some detail shots. The boards are good, but I spotted a small error at the end. Have a look for yourself:
The drills are all centered, the silkscreen seems to be offset by a bit though. Bummer.
The error is – excuse the pun – microscopic and won’t affect the functionality.
I know it sounds weird, but it’s a bummer you get exactly the amount of pcbs you order.
if you don’t order pcbs often this will most probably sounds weird. But usually you get at least one spare pcb. I like to use them for fitting tests or if something goes wrong while assembling.
Well, thats probably complaining at a high level.
Ah, what’s also pretty nice at Seed is the opportunity to order flex pcbs directly and having your boards plated with hard gold. That’s quite impressive, my fab won’t do that.
