Hello, Voids in BGA can not be eliminated. You can only minimize them by reducing the solder paste volume. Try to bake the plastic BGA's and PCB both as per the standard. Check the PCB at the BGA locations if the via's are masked.Masked via's result

Hi I'm trying to plot a LSP profile to reduce void. But I do not have much info about LSP. Does anyone know what are the specific times and temperature of the LSP profile? And are there any ways to eliminate solder void other than changing profile

Can you use one of those hot-dog rollers (cookers?) you see in the corner convenient stores to keep the paste tubes moving to eliminate the separation? Ya know, the cookers with the week old hot dogs on it that are all shrivelled up?

Colored paint pens by Abbeon are inexpensive and cannot be removed with things such as flux-off. They have a ton of colors and all it takes is half a second to touch each board. Remember, this will NOT eliminate or solve your defect problems(like m

I don't know what's recommended but I do know that bagging with Intercept eliminates all oxidation in tin parts and platings and the need for dry packaging to boot. Email me if you'd like more information. dasalintercept@hotmail.com

Thanks for your help. We try the de-ionizer fan, helps some what but did not eliminate the problem. Can you tell me which model are you guys using.

This phenomenon is caused by a high amount of halogens (Cl, Br etc.) used in the flux activators or in the flux surfactants. We've seen effects creating all colors of the rainbow. Changing to No-Clean (halide-free) will eliminate this color effect.
