Actually that reminds me I remember one place I visited that wore two heel straps for saftey purposes. The reasoning was that if you touched a live wire with one hand and only had the heel strap on the other foot the current would go through your he

John, I'm sure your right! Cause my partner is laughing at me over the idea. "How often do we want HazMat at our door" "Do we really want to be friends with them on a first name bases" " Do we want to make friends with their friends,OSHA" I still thi

Does anyone know where I can get conductive benchtops? NOTE: I don't want a mat and I'm already using (and unhappy with) a laminate surface glued to a wooden table. Any and all info would be very much appreciated. BTW: I'm also looking for conductive

Mat, Are you sure you should be using SnPb HASL boards if you are doing prep for lead free? If you aren't actually going to comply with RoHS then fire away. Nearly all of our assemblies are now ENIG and as any re-design comes up on a HASL board it is

OK so you're stuck with gold. Not all that bad unless you're paying for it. Gold is very flat compared to HASL, so you should have no problems printing. This should lead to good placement as well. But after oven you mat have a big contrast betwee

Thanks for the answers. Hi Dave, I'd love to use some of the durastone we have here, or some Durapol or Delmat (never used Glastic before though), however we need a compliant material for the blade to go into slightly, otherwise they tend to snap or

Advertisements are not always 100% accurate on technical issues. You don't want instand static discharge. A wrist strap with no resistor could cause that. Therefore put in a current limiting resistor to make the charge dissipate slowly. Does anyone
