John, I have never seen black pad covering a majority of the board, that would be a scarry thought. I think he is talking about building modules (sims dims) and getting soldering spatering on the gold edge connectors. We went the rounds with that s

Ken, we always build the bottom side of the board first. That also insures that there isn't any problems with the actives being reflowed and falling off in the glues curing process. By the way we do both paste and glue on the bottom of the boards t

Are these blades coated with something like PTFE (teflon)? If so does the coating flake off over time. Incidently I just got a pice quote and they are 4.5X that of our standard MPM nickel plated spring steel, so I wanted to make sure they would last

Curtis, They have a 'permalex' coating bonded to the metal. We see no signs of flaking. They are pricey but they do work, we had metal blades from the OEM, they were absolute trash (not MPM). We run 16-6 and they last at least 4 to six months in

These parts are flat chip resistor arrays that have 4 end terminations on each side. It looks liek an IC but is typically in an 0805 and 1206 package type with convex terminations. .031" pitch from termination to termination and .011" spacing between

Based on what you have said so far it would be worth trying extra pads and as you may know the drainage pads should be a minimum of three times the length of the pads before them to be effective. Also take some parts stick them to a glass plate and r

Jason, We have been running both the high pressure and the ultrasonic washers for several years and there is no comparison. The ulrtasonic (smartsonic) does a great job on all the normal pastes, and when we changed part of our production to a new ep

Does any one have any experience with the transition automation permalex squeegee blade (I called them and they couldn't tell me much), or any blade other than the typical nickle coated spring steel. Part of our production has been moved (by our cus

Hello Kris If you do have and OSP coating I'd say Curtis has nailed it. But you seem to have references to gold. Does this board have a standard nickle/gold finish. If so what sort of "solder on gold" problems were you having? Reading between the
