Conformal Coat and RTV

Electronics Forum | Wed Jan 03 21:20:22 EST 2007 | davef

Comments are: * General purpose RTV (RTV-108) releases an acetic acid (vinegar) during cure and corrodes copper, brass and sensitive metals. It is therefore NOT for use in delicate electrical or electronic applications. However, there is an electrica

Adaptable PCB support systems for use in pick and place machines?

Adding to my previous message this could be solved fairly easily for the general case with a jig made from 3.2 - 4mm aluminium aircraft grade plate. you would machine the bottom side edges to give a 1.6 mm thickness, then machine the top side to leav

ITAR and AS9100...like peas and carrots?

Electronics Forum | Wed Aug 12 15:50:01 EDT 2009 | davef

Wouldn't think of them as peas and carrots. Maybe, tree and carrot. ITAR: Export regulations that are specific. Board fabricators may choose to be ITAR registered. AS9100: Aerospace tailored version of ISO9000. So, it's general. In it's base form, AS

Touch-up and Inspection Process

Electronics Forum | Thu Mar 03 11:23:50 EST 2005 | Slow Ride

Generally QC is a different deptpartment than touch-up people. Most touch-up people are just general operators, so to keep their job they always see the solder joint as "not enough". Q.C. people are generally a bit better, but know they may be call

Hi Guys, Sorry for asking stupid questions. Are SPC, PPM and DPMO related to each other? Do they affect each other then? What is their inter relations? Can someone explain to me what are their purposes? thanks

Wave and Reflow Profiler

Electronics Forum | Mon Feb 18 13:11:41 EST 2008 | tonyamenson

Are there profilers that I can use over my leaded and lead-free wave that can also profile my reflow ovens (leaded and lead-free). I'm not that familiar with either but as I learn I can't help but think that there should be something on the market t

NADCAP and thermocouple calibration

Electronics Forum | Thu Aug 08 13:09:38 EDT 2013 | cyber_wolf

Hege, there is no actual calibration of the thermocouple itself. You can however verify that they read correctly. Heller sells an option on their reflow ovens specifically for this purpose. I hoping that someone chimes in here that is NADCAP certifi
