Has anyone done any testing with UV tracer in Parylene processing? Does it cause adhesion problems? Does anyone have any data they can share on this.

Lou, Oh really? Why's that?

We do parylene coating and really frown upon using a UV additive. Technically, it's a contaminant to the parylene.

I had read somewhere that parylene absorbs UV radiation, and therefore offers very low UV protection. So, yeah probably not a good idea. Plus since it's vapor deposited, unless there is no access to a surface, all surfaces are covered.

how does polyurethane used for wood floor coating differ from urethane conformal coatings sold for circuit boards? where can i get uv tracer to put in oil based urethane?

Hopefully the coating does contain a UV tracer. We used a silicone years ago that did not, but UV did make it fluoresce to a degree, you just couldn't ensure 100% coverage. One time we did have a problem with the coating getting on connector pins,

This is a late reply, but from my experience a really good removal station is one made by a company called CCRCo. They make a micro-abrasive station that addresses all the ESD concerns. They utilize a reusable media that is really cost effective. The

We had a similar problem with gold contact pads. Cleanliness is paramount. If you are using foil tensioning system, wash the foil in a stencil wash before use as the cardboard cassettes may be contaminated. Be very careful when loading into a frame f

Hey that was me way back! Anyways, use Dow 3140 (self leveling) or Dow 3145 (peanut butter consistency) and call it a day. No out gassing/acidic properties. 3140 also contains a UV tracer for black light inspection. Any tall caps should be epoxied if

The easy part is to determine which parts should be coated. The harder part is making sure the parts that should not be coated do not get coated. I don't even want to think about the amount of labor and materials I've lost due to conformal coat get
