-If the aperture volume is the same, there will be more solder on the HASL finish joint due to the solder already present on the pad. This difference is not usually enough to cause insufficiant solder volume but will "look different". Sometimes an

Has anyone had an issue with changing from a HASL surface finish to a LF HASL finish if it is still being used in a leaded process? Also we are having issues with the planarity on the fiducials with the HASL finish. Are there any suggestions or ch

Actually they are complimentary. SMOBC describes how the solder mask shall be applied (but not the type, surface finish, color, etc). The other terms describe the type of surface protective finish applied to the solderable surfaces. You need to sp

Is anyone has experience on problems with press-fit on Ni/Au board finish. Connectors pins are SnPb finished. I am particulary interested by experiences or documentation in very agressive environmental conditions (avionics or space buisness) Thanks r

Which is the best surface finish to be used on non- solder mask defined pads in terms of cost and reliability? What are the advantages and disadvantages of the various surface finishes such as Ni/Au , Cu OSP , Ni /Pd and HASL.

Indy, We use Palladium silver surface finish parts for silver epoxy attached parts only. It is our understanding that this finish is not for solder, but only silver epoxy attach. I expect that is you problem. Dave

We received bare PCB's that were supposed to have been finished with immersion silver because of BGA locations. The boards were finished in ENIG. We are concerned over any reliabilty problems that might occur as a result of using ENIG at BGA locati
