IPC-A-600G, 2.9 Solder Resist [Solder Mask] [snip]"Solder resists are used to limit and control the application of solder to selected areas of the printed circuit board during assembly soldering operations and are sometimes used to reduce dendritic f

Scratches on BGA solder resist

I have been trying to tell people at work that minor scratches on solder resist on BGA will not effect functionality of BGA, instead they want to attempt repair of these scratches. Any suggestions.

Hi Roderick, Guess it depends on how you define "minor". If it is just a visual blemish in the mask, there will be no affect o the BGA. If it is through the resist there may be a chance of solder shorting, which will affect it, I doubt it but poss

Water soluble solder resist masking

Electronics Forum | Fri Dec 12 10:28:30 EST 1997 | David Syracuse

I am interested in locating a water soluble resist mask that does not leave a residue after wash and is easy to work with during the screen printing process. I have tried the Alpha Metals 110 and 220 solder mask and have found that it does not leave

Clearence of solder resist from QFP Leads

Does anyone have design knowledge of why some manufacturers remove solder resist from the area around pads on fine pitch devices? What purpose does it serve? I only know that it would be better for AOI as you would not have light being reflected fro

Clearence of solder resist from QFP Leads

Hi Simon, The main reason that it would probably be removed would be do to lack of clearance for a soldermask dam from pad to pad. typically if the clearance from pad to pad is under .008 the solder mask dam would be removed. Min recomended dam siz
