Nordson has a viscosity control system and a laser fan width control option. We use the viscosity control system on our machine. Basically it heats the material to a set temp. The laser fan width measures the spray pattern width with a laser and a

They're open ended on the thickness (read that as, have no clue). They've indicated that they would like the coating to protect the circuitry from ESD, and mechanical shock. They also would like to be able to see the LED's through the material. An

So I'm starting up a conformal coating process from scratch (again, although it's been about 10 years) and I'm looking for the best option for verifying thickness. I plan on going the "coupon per setup" route which will encompass both our manual spr

I'm not sure if your customer will allow it but consider sealing the perimeter of the connector where it meets the board with some kind of sealant or staking material. Cure it then apply tape on top of it. Then all you have to do is remove the tape a

Vinyl ESD floor tiles are probably the most expensive approach to "permanent" flooring, about $8 a square installed. VPI and 3M are reputable suppliers. Let me digress on ESD floor "waxes", the earlier poster�s comments are well taken, but the bigge

Be careful about the material you choose. All the materials out there are basically glass-filled epoxy composites, but they are different blends with different fillers. Some of them have carbon in the matrix to make them ESD safe, but it also short

At this time we will be hand spraying acrylic, probably using spray cans until we decide on a spray gun or an air brush, and get one ordered. Our volume is too low to even consider an automated system. Our current requirement is on an item designed

Anyone has experience with Humiseal 1B31LOC and 1B31? Their material properties(physical, chemical, temp. etc) are fairly much the same after cure but there are some differences when they are at liquid stage. We are currently using 1B31 but is planni

I don't think THEY (Humiseal) know how their material cures. I have a data sheet from them for 1B73, and it says 24 hours at room temperature or 30 min. @ 170�F. We use our in-line oven mainly to dry the material and make it tack-free. You would

I've used handheld ultrasonic gages on silicone in the 4-12 mil range. A coupling agent is needed between the transducer and the material - we used DI water vs. the supplied gel. Fairly straightforward, setup is done off a reference thickness of ma
