Try using some of those new polyimide stencils. They are 8mils thick and can prevent shorting if it is due to solder mask problems or too much paste. http://www.solder.net/technical/tips.asp BWET

-Cartridges will fit an auto dispenser on the screen printer or a hand dispenser. Will waste some paste at the bottom of the cartridge. -Jars will be a little harder to deal with. They are messy. Can get all but the last couple of grams of the pas

We are using AIM WS300 solder paste and are experiencing excessive voiding on our BGAs. We have exhausted reflow profile alternatives and just can't beat the voids. Has anyone had success with this paste on BGAs? If so how?

You can contact Hitachi High Technologies America, they are still supporting these machines (972-615-9102). It also sounds like you could have a servo problem.

We are using QFP & other IC's in SMT but not using the antistatic pecautions. I want to know that what effect can be on IC's in future. Because we did not get any IC damege immidiatly. How long after this will affact the IC,s.

The larger BGA's can also warp more under higher temperatures which causes ball lift, more noticable towards the edges of the package.

Hi, I have seen demos of these scopes, and don't think they really show you very much. If you profile your board right, and drill up to solder a thermocouple onto the inner balls of the device so you really know your getting a good profile, I don't

thermal cycling chemical reactions (can occur slowly) they were only touching before and not really a solid solder joint
