Plextor SCSI PlexWriter

Continuing my clear-out - I have a Plextor SCSI PlexWriter on offer. This came with a bundle of Archimedes gear that was in daily use by the seller. So, I'm assuming it's working (full refund if not!). No idea of value so let's go with the £25 including P&P within the UK! Note: it's heavy - Just ove...

Re: Proposed: "The Ultimate Electron Upgrade"

I'll do a costing - Phil . . . could you send me a BoM, please?

PCB price is not going to be the issue. But let's wait and see what the BoM cost is. And then I'll check around various PCB houses that offer a manufacture and build service.

JLC, afaik, do continuity testing based on an analysis of the gerber's nets with flying probes.
Flying probes takes an age this video shows the difference in speed, however, I doubt we'll be able to afford the 'quick' method as it requires a dedicated bed-of-nails!

Re: Proposed: "The Ultimate Electron Upgrade"

I agree with Dave's comments about board testing. This board has supposedly undergone electrical testing at JLC, but I'm not sure what that means. Did they test continuity for every one of the BGA balls, or was it just a sample of various pads to make sure nothing had gone badly wrong? I designed i...

I suspect the rubber in the foot degraded (chemical reaction) rather than heat. Although chemical reactions are of course speeded up with increased temperatures... I’ve seen people after feet before, but can’t remember where. So maybe worth searching the forum and the web :wink: Mark Mark Haysman (...
