The coating is pliable and is air cured for 24 hours. The potting compound goes into the top assemnbly in 3 diferent stages. The circuit boards are coated using urethane type conformal coating. The unit is also placed into an ESS chamber -40� to +

Are there any guidelines when building products with flex circuits? Any heat profile guidelines? Wash Guidelines? Handling Guidelines. Is it best to run on the same line?

Just take care about reflow profile with this kind of product, you can get a bad-formation in your PCB (Flexcable or your flexcircuit) however you want to call... This bad-formations looks like a solderballs (Microscopio) Regards Jesus

Hi, What would you consider significantly different about lead-free on flex circuits than tin-lead of flex circuits ? Have you published your experiances that you encountered while changing over to lead-free solder paste from a tin-lead paste ? T

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

You misunderstand...I am not a CEM rather I am representing a placement machine manufacturer. My question is to you as to your requirements for your application.

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.

We use Dymax �Ultra Light-Weld�. We use an ADAC Technologies handheld for uV cure. What do you use?
