just out of curiousity, why the special nitrogen cabinet concerns for gold plated flex PCB? common "myth/fact" is gold is an "inert" coating layer that is not going to react with room environment conditions *that much?*. Am learning here, so would ap

Our first choice in determining the composition of metals would be to use Scanning Electron Microscopy (SEM) / Energy Dispersive Spectroscopy (EDS) analysis.

Dave's point is right on the money. This would be a destructive test..needing microsectioning. Cal Communications Test Design, Inc

Thinking about it, if I was designing machines and based on my experience I would offer a high feeder count, high flexibility machine and low speed. In addition another machine with low feeder count, not flexible (8mm parts) and high speed.

I'm considering the Panasonic Soft Beam for soldering through hole parts, How well do they work ? , How much time does it take to solder 400 solder points ? Thanks, Steve

Hi, Would it be likely that the component carrier you re using is too large for the component with the result that the vibration during feeder indexing is overturning the component ? comments
