I am having cleaning problems when processing PCB's which have TAIYO solder mask on them. After processing, hand soldering and cleaning, a sticky residue is remains, resulting in a cosmetically poor finish with tide marks etc. Other soldermasks do no

Does anyone see any issues in mixing SMD and NSMD pads within one BGA footprint. We have high current pads which we want to make SMD and the other signal pads to be NSMD

Can anyone recommend ways of reducing damage to solder masks ... a new wick perhaps. I find that using standard wicks the imposed damage is un-acceptable. Also any good links on the subject of bga rework would be really appreciated in earnest ...

Good Day Everyone, I have a BGA rework that has some chipped/damaged solder mask that will need to be repaired prior to BGA replacement. I was wondering what materials are being used in the industry for this type of application. Any help would be g

We usually get some mask material from our board house. It cures with heat so it works really well in our applications. Be wary of the "overcoat pens" they don't seem to hold up under heat and thre solder will flow right underneath it during BGA a

Hello, We have designed a 160ball bga substrate. Now we want to use the same substrate for the 145ball version of the product. All are the same, the package size, ball pitch, solder ball size only the number of balls will change. We will use a new s
