Ours is the same configuration as that, we run with neat Humiseal 1B31 through the needle valve and a 1:1 blend 1B31/Butanone (MEK) in the spray valves. Programming is done via a PC using the pendant and the path is point to point trained on scrap P

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

All, On my Wave Machine the Coating on the fingers "pcb carriers" is coming off. They are way way way way overpriced to replace if all possible. I would think there is someone out there that could re-coat them??? If so what is the companies name/ c

Does anybody have a source for jigs/tanks for a manual dip operation? We are stuck conformally coating PCBs manualy and the volumes do not justify us buying a 100k automated machine. there for we have to manually dip the pcb in a silicon based coatin

Does anyone have any experience with underfill of HD connectors? New customer wishes to underfill 6 HD connectors that have been pressed into PCB. Capillary action is causing the conformal coat to wick up into connector. Material is acrylic.

We are experiencing poor wetting on various components placed on a PCB with En-Tek coating. Is anyone else experiencing simular problems ? We have the following questions: 1. How can the thickness of the En-tek coating be measured? 2. Is En-tek vol

| Has anyone out there tried to parylene coat plastic parts prior to soldering them to a pcb? I'm looking at several potential applications where fewer than 5% of my components on a pcb are plastic, yet from a reliability aspect (environmental condit

I would suggest lowering the viscosity even more. Humiseal even sells 1B31 pre-mixed specifically for spray machines and the highest they go is 65cps.

Thanks for the advise, but we want to change the lacquer/thinner ratio at the last step if we don't have other solution.

That's a reasonable question for a supplier to ask his / her customer. It depends ... It depends on the materials use in the process the assembly and the reflow temperature recipe
