Preparing for small scale production of PCBs

For a number of years, we’ve been thinking about the future of production and manufacturing. While everyone else seems to be “scaling up” and embracing globalisation, perhaps we’re been a little perverse in going the other way. Or maybe...

Nail varnish as solder resist

We’ve been doing a lot of trying things out lately, and not a lot of actually getting much done. But sometimes that’s ok, if only to satisfy your own curiosity. One thing that’s been bugging me is how close we got to making some really useful pcbs...

Press-n-Peel for the win! PnP FTW

We went crazy today and splashed out on a new laser printer. The big old Xerox is getting costly to keep buying consumables for, so we got a cheap, compact Brother HL2130 from PC World.Yup, it was extravagant. Yes, we could have got one cheaper online for...

Laser etching PCBs update. Don’t bother!

We’ve made about half a dozen different PCBs using our laser etching and laser cutting methods for creating the etch-resistant mask. And while creating the actual mask is relatively straightforward – compared with press-n-peel or exposing photo-sensitive...

Etching PCB resist with an LS3020 laser cutter

This time we tried making a PCB with no “filled plane” between traces. Normally we flood fill all the spaces between traces, just so that the ferric doesn’t have as much exposed copper to etch away. But out of interest, we made up a PCB with no...
