Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reow
soldering, see Figure 23.
For further information on temperature proles, refer to Application Note
AN10365
“Surface mount reow soldering description”.
16.3.1 Stand off
The stand off between the substrate and the chip is determined by:
The amount of printed solder on the substrate
The size of the solder land on the substrate
The bump height on the chip
The higher the stand off, the better the stresses are released due to TEC (Thermal
Expansion Coefcient) differences between substrate and chip.
16.3.2 Quality of solder joint
A ip-chip joint is considered to be a good joint when the entire solder land has been
wetted by the solder from the bump. The surface of the joint should be smooth and the
shape symmetrical. The soldered joints on a chip should be uniform. Voids in the bumps
after reow can occur during the reow process in bumps with high ratio of bump diameter
to bump height, i.e. low bumps with large diameter. No failures have been found to be
related to these voids. Solder joint inspection after reow can be done with X-ray to
monitor defects such as bridging, open circuits and voids.
