During initial profiling we shoot for 15% or less voiding on our BGAs. During production runs we consider voids under 15% to be ok. Voiding between 15%-25% we string tag and pay more attention to during test. Over 25% we consider a reject.

We seem to have voids show up in one out of 5 BGAs during x-ray inspection. The x-ray is set up to accept the joint with anything less then 30% void area. I need anyones input of what during the process we can do to decrease the voiding and/or a good

First published in the 2012 IPC APEX EXPO technical conference proceedings. We investigated the micro-void formation of solder joints after reliability tests such as preconditioning (precon) and thermal cycle (TC) by varying the thickness of Palladium (Pd) in Electroless Nickel / Electroless Palladium / Immersion Gold (ENEPIG) surface finish. We used lead-free solder of Sn-1.2Ag-0.5Cu-Ni (LF35). We found multiple micro-voids of less than 10 µm line up within or above the intermetallic compound (IMC) layer. The number of micro-voids increased with the palladium (Pd) layer thickness. Our results revealed that the micro-void formation should be related to (Pd, Ni)Sn4 phase resulted from thick Pd layer. We propose that micro-voids may form due to either entrapping of volatile gas by (Pd, Ni)Sn4 or creeping of (Pd, Ni)Sn4.

? After SMT machine soldering, there will be some voids in the solder joints. These inevitable voids will cause some potential risks to the quality of the whole product, and the most direct manifestation is that the life of the product will be far less than expected

. This led to less voids in the dispensing area, which increased first pass yields. Watch this video to see a live demonstration. Reduced fluid waste, greater process control, and higher throughput yields are just a few benefits the automotive supplier gained with the new jet valve and robot system from Nordson EFD
