greeeg 460 Posted November 19, 2015 Author Share Posted November 19, 2015 The masking tape sorts out the melted edges on the mylar. I've not tried kapton myself, but I believe it should cut well. The slightly misshaped holes are entirely down to the fact that I'm cutting small rectangles at very high speed. Asking the head to turn a fast sharp 90 degree corner means there's some overshoot and vibration. You'd never really notice if the shape wasn't so small. Raster engraving might solve this completely. I've not looked into this as it's certainly good enough for my current needs. LQFP and QFN worked fine last night, despite using crusty old paste that I thinned out with flux and stirred with a screwdriver! I'll try taking some photos. Yes, I have never tried to run mine that fast yet. I've done more work on the code. Not worrying about code size. ( It is around 7kb, basically maxing out the poor G2452. ) And the forward voltage diode drop voltages for anyone interested. bluehash, cubeberg and terjeio 3 Quote Link to post Share on other sites
