| Steve, | I know it is tempting to go for the cheapest method of applying conformal coatings but I must warn you. If you are a contract manufacturer then you don't want to limit yourself in the types of coatings you can work with. Just as soon as yo

| Be consistant on: | 1 Keeping the coating material thinned. | 2 Using the same dipping motion on each board. Amen on thinning the coating, and you might also be concerned about the curing mechanism for the coating. Moisture-cured and 2 component

Hey youse guyz... We're finally getting our first real job at the start-up I'm working at. It's actually a pretty unique little board too. Simple as all get out, but unique. You're not gonna believe what this goes into...guess? (I bet ya' you'll neve

We have used many ways of measuring but all are either messy, inconsistent or time consuming. We have done wet, glass slide dry, etc. We are currently using a kapton tape dot system. Spray the board, remove the dot and measure it, subtract the thick

How thick are their requirements? A barrier can be made using peelable latex. That would then require manual or automatic dispense of latex to create a dam. Then you should be able to use an automated dispense system with a large orifice and flood

I am going to be using a pressurized dispenser for Chemtronics CM1 peelable mask. I need to find a solvent that will work for flushing the system. I tried Xylene that we have here and it does ok, but not as good as I'd hoped. It works very well fo

Dear Upinder, While reading the posts at the SMTnet forum I noticed your post pertaining to Curing ovens for use with Conformal Coatings which require regulated relative humidity to activate the cure. My company, ETS, is the manufacturer of Nordson's

For the capacitors that Yageo analyzed... Were they taken out at representative points in the process?? ie. were samples taken from pre-assembly, pre-ICT, post-conformal coat, post-final test? You note that the parts 'seem' to be ok up to ICT. And

Oh yeah, so we have a auger valve similar to that on one of our other machines that we use for dispensing SMT glue, and solder paste also. We have a conditioner that we flush it with at EOD when in use, then we just let it sit idle with the condition
