Lucent Technologies Inc.
Mounting and Connections
(continued)
Lucent Technologies/FORCE ICs assembly procedure recommendations for the LG1605DXB are as follows:
I
Board solder pattern for the 1605DXB package base should not exceed 50% of the package base area.
I
Back lighting can be used during the pick and place operation to silhouette the package in order to eliminate
reflection problems with the solder on the bottom.
I
Set the lead spacing tolerance to ±0.012 in.
I
Insertion pressure should not exceed 125 g.
