I have just taken on a nice little job to make a tool for releasing multiple component assemblies from a PCB (printed circuit board) and was wondering if anyone had any advice on the cutting clearances for optimal tool life?
The PCB is 1.2mm thick and uncoated.
I did a test piece in an other tool with 0.025/side clearance and the edge was pretty clean but I have no idea how long the edge will hold up, wether PCB is abrasive etc etc. I have spent a few hours trawling the net but can't find any data whatsoever.
Any ideas or experience would be great...
