WLCSP Assembly / Design Notes
For PCB manufacture with BelaSigna 300 WLCSP,
ON Semiconductor recommends solderonpad (SoP)
surface finish. With SoP, the solder mask opening should be
nonsolder maskdefined (NSMD) and copper pad
geometry will be dictated by the PCB vendor’s design
requirements.
Alternative surface finishes are ENiG and OSP; volume
of screened solder paste (#5) should be less than
0.0008 mm3. If no prescreening of solder paste is used,
then following conditions must be met:
1. the solder mask opening should be >0.3 mm in
diameter,
2. the copper pad will have 0.25 mm diameter, and
3. soldermask thickness should be less than 1 mil
thick above the copper surface.
ON Semiconductor can provide BelaSigna 300 WLCSP
land pattern CAD files to assist your PCB design upon
request.
WLCSP Weight
BelaSigna 300 WLCSP (B300W35A102XYG) has an average weight of 0.095 grams.
DFN Pin Out
A total of 44 active pins are present on the BelaSigna 300 DFN package. A description of these pins is given in Table 8.
