Title: Anyone used 0.2mm PCB material?
Post by: tufty on Thu, 26 November 2015, 06:04:51

So, shopping around for PCB material, along with the "usual suspects" of 1.5 / 1.6mm board, I've come across a few 0.2mm boards.  Apparently FR4, so fibreglass board with coper clad.  Seems to me that, with a few judicious cuts, it could be eminently usable for making contoured keybowls.

Anyone used it?

I've never used it yet but found this 0.4mm thick PCB at local store. Even with 0.4mm it can be flexed considerably and cut with scissors as pics show.

I wonder what thick board Kinesis and Model F uses. They look thicker than this.

My Kinesis uses 0.4 mm board.

That's more purchases, then.  Need some 0.8mm double-sided to make a killer smart card, too.

Give me a couple minutes and I can measure a terminal F122, and the Xtant pcbs, along with a stock XT.

Just took some numbers. 

Terminal F 122 and stock XT pcbs were both the same at .0365" which comes out to 0.927mm, and the Xtant pcb was .0341", comes out to .086614mm.  Measurements were taken in inch with this.
