"Ionization of the air causes an increase in conductivity..." I have an Ionograph and everytime I open the test lid cover the Baseline Stabilization Resistivity Value s by 60M Ohm-cm. My question is: Is there something to worry about our facilities

Casimir: Resistivity of Solvent Extract (ROSE) testers measure ionic contamination by washing boards with a DI water/IPA solution. (No-clean people: Stop and go on to something else.) The testers are process control instruments used to monitor a

Can someone suggest what material I have to use to protect components by electrical discharge on ptfe based boards? It should have high resistivity, thermal stability (-40 +70 'C),perfect adherence on ptfe... Many tahnks

| Cpk's on top flight ovens (e.g., Conceptronics, Heller, Electrovert, Vitronics) vary wildly, from 1 to 2+, between different supplers. The suppliers don't seem to understand Cpk's. A supplier's rep whose oven has a Cpk of 1.0 told me: | 1. Cpk's

I would like to address several issues. First, your reflow is 150 PPM for the same exact assemblies that have lower PPM's? or are you giving a 150 PPM rating for all products produced through the reflow process in a specific time period? Reflow is a
