How are you removing the remnant cured coating materials once you scrape. laser ablate or use walnut shells to blast coating material from a PCB? We are using a soft bristled brush or a vacuum source. What about liquids such as cleaning solutions o

Paralene, Paraxylene, or other vacuum deposited coating will require this method to remove the coatings. UR and Acrylics have solvents, as Rob above has mentioned. Plastic bead media and wheat chaff are ones that I know have been used for Paralene

Cheery disposition??? Would a few ;-) ;-) ;-) help? [Oh and look who is talking, the one planning the Mickie D gig after the traces on the this board start vaporizing with the fuseable link schtik.] Are you sure you're getting flux all the way up

Eric, The Kolb RB6D (and the RB5D) are not ultrasonic cleaners. They are high pressure spray cleaners. I would not recommend high pressure spray cleaners for misprinted assemblies with previously placed components (unless you don�t mind solder pas

Maxtim- I have used APE's Sniper, airvac, Mecal's 3500, PDR, Pace, and MArtin's rework stations. APE Sniper does the Job but to much automation and not user friendly software. PDR is to much IR and no convection. Metcal's work good now with the ne

Bollocks!!!! We are unfamiliar with the term overturn, but it can not be that uncommon. Our intial inclination is to barrel into this SMT Engineer's nap-zone and blast him, but it might not be a politic approach. So, maybe we'll temper the tack we

Danger Will Robinson� Danger! Never mix a post-reflow cleaning system with a raw paste removal application (particularly on an inline cleaning system)!. The paste that comes off a screen contains solder balls that are so small, they will eventuall
