I need to construct test boards for which will be repeatedly subjected to Highly Accelerated Stress Screens, (HASS), and am looking for recommendations for materials. Would an Epoxy Glass or an Epoxy Glass Composite be least suceptible to exposure t

Hello everyone, Is it possible to quantify what you consider "Low Level" vs. High Level x-ray exposure? Is anyone aware of what level of exposure the airlines typically use in security applications? Thanks, Sean

OSHA legally requires employers to: * Monitor air quality * Restrict exposure * Maintain hazardous substance level below Permissible Exposure Level (PEL)

Steve, Dame Edna is from Australia... but keep it quiet, we don't need the exposure! :O)

Last year I had my doctor do a lead test during one of my regular blood tests. My exposure at work is similar to most of you, I'm sure. I've been doing this for 13 years now. We do predominantly leaded solder processing through SMT and wave. I wash m

Why not use a cabinet like those used for limiting the exposure of misture sensitive components to humidity?

If there is damage of the glass coating or exposure of the resistive element it is a defect.

Take note that contrary to popular belief, it is not acceptable to assume that the floor life clock will be temporarily stopped when components are put back in dry storage following exposure to ambient conditions exceeding one hour. ... why doesn�t

We have now switched to Kester EP256. During our solder paste evaluation, resistance to humidity was one of the selection criteria. We printed multiple boards, then exposed them to 85�F/65% RH. At 30 minutes, 1 hour, 2 hours, and 4 hours exposure

Probably: 1. Laytex reaction 2. Some other exposure at work or home FWIW: Cleaning anything with alcohol sucks. Alcohol toxicity could be your problem, but not like you think (hand contact). Consider inhillation as the exposure point. Work sho
