Layout information
properly designed board essential part RF/microwave circuit. Keep signal lines short possible reduce losses, EMI, stray inductance. multiple, separate low-inductance-plated vias ground plane each ground bump. chip-scale package (UCSP) bump pitch 0.5mm (19.7mil) bump diameter 0.3mm (12mil). Therefore, solder spacing 0.5mm (19.7mil) centers, size 0.25mm (10mil), solder mask opening 0.33mm (13mil). Round square pads permissible.

UCSP Reliability
chip-scale package (UCSP) represents unique package that greatly reduces board space compared other packages. UCSP reliability integrally linked user's assembly methods, circuit board material, usage environment. Operating life test moisture resistance remains uncompromised, primarily determined wafer-fabrication process. Mechanical stress performance greater consideration UCSP. UCSP solder-joint contact integrity must considered because package attached through direct solder contact user's board. Testing done characterize UCSP reliability performance shows that capable performing reliably through environmental stresses.
