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

Not sure exactly what kind of coverage your looking to get but we use Dow Corning 3-1944, it's room-temp cure and rather thick, (think warm honey). But we have found it useful on several projects. http://www.dowcorning.com/applications/search/produc

We assume by "stencil tension" you mean a measurement of how securely [or how tauntly] the stencil foil is held in the stencil frame. If so, we do not know how you would go about making your "30 ~ 50 N/cm" limit measurement when verifying conformanc

(or just some static-safe foam tape) I need to seal a wire terminal block to a board for conformal coating purposes. Currently we glue it to a shim and glue the shim to the board (yuck), but I want to use die cut gaskets if I can make it cost effec

We are using Humiseal 1B31 and polyester dots for masking. We are spraying this in a Binks sprayer mixed at almost 1:1 with 521 thinner. Whe are seeing the coating creating thin halos around the poly dots as if the dots are "rejecting" the coating. T

From my previous experience with silicone, it tend to be need to spray with thick coating(s) and it's more watery. The boots doesn't work too well in those cases. Just a note, now I am no longer working with silicone. For conformal coating, best m

Also coating costs depends on solids content vs final dry film thickness. Some newer UV coatings are 100% solids, so what you put down you get on the PCB after cure, use no solvents at all. So a cost to look at are qty of PCB per litre of material. T
