Recent discussions have risen lately regarding the in-house transferring and handling of populated printed circuit boards using unpainted wooden slats with notches cut in them. Wood may be at the high end of the neutral triboelectric scale but does

You are correct about the location of wood on your friendly neighborhood triboelectric scale. But unfortunately for us [and fortunately for the ESD protected material board rack salesperson], the scale does not recognize the effect of the moisture t

Yet Again Dave spills his pearls of wisdom. Dave is correct in the moisture content wood absorbs. I know we have all visited factories with wood board holders and such. I have actually seen wood carts with drag chains. Also, keep in mind static can b

Poor man's approach to assessing coplanarity issues: * Get two pieces of 2X4 wood that are the same length, about three inches long * Cut the end of one of the pieces at a 45* angle, so that the 45* angle cut leaves a face on the four inch side of th

Dave, Your response might have been helpful if you would have left off the extra, comical(?), comments. I am American and I still couldn't figure out what you were trying to say sometimes. Searching the web to find an ESD program and training seem
