Not all polycarbonates are V-0. I tend to use Valox: easy to both machine and hand-cut, good dielectric (have tested single 0.003in sheet to 5kV), most thicknesses are V-0 rated, and has decent (non) water absorption properties.
I also like to have the mechanical designers put a sheet between chassis and PCB so that any bad SFC will not result in failure of subsequent hi-pot. luck, Brian -----Original Message----- From: [email protected] [ mailto:[email protected]] Sent: Tuesday, August 12, 2003 10:55 AM To: [email protected] Subject: 94V-0 question I need a sheet of plastic that goes between a PCB and a metal enclosure. This is to make a creepage spec. What plastics are good for this? Will polycarbonate be suitable and have a 94V-0 rating? Thanks.
