Does anyone out there can let me know how to clean a Entek Coating Board if I have a misprint during solder paste printing?

I think you are right. According to IPC-7526 section 6.2 says that using compressed air to blow out paste will damage the stencil, especially between fine pitch apertures. It can also broadcast solder paste onto other surfaces or personnel. I recomm

We have begun using a PCB with Organic Surface Protectant. We normally run boards with non orgainic protectant. We can wash these boards with our ultrasonic cleaner using Zestron SC202 and a separate Hot/cold rinse system with an air knife. This r

You weren't specific about the OSP that you use. We use Entek Plus CU-106A. Yes, just about everything removes Entek, especially if there's heat involved. Ethone states: * Alcohol strips 70% of the coating * Water removes 15% * Kyzen Lonox only t

Michelle, Our experience with no-clean solder pastes has been that water washing a mis-print is a bad idea. We've found that DI water does not do a sufficient job removing the no-clean paste (the same goes for stencils). Instead, we have washed no

I just need a clarification on NC254 No clean solder paste. If we have parts on the bottom side of the board that already are soldered and we go to run the other side of the board and it was misprinted, is it ok to run thru the washer? I just need

What is the preferred method of cleaning misprinted double sided No-Clean boards which are assembled on side 1 ? What type of equipment is being used ? What solvents / detergents work well for a variety of solder pastes / glues ?

I've read different views on this but the best results i've seen are from when the misprinted PCB is put directly into an automated 'spray-in-air' cleaning machine and cleaned using an appropriate cleaning chemical. Any attempt to manually clean the
