Assembly / Design Notes

For

PCB

manufacture

with

BelaSigna

R262,

ON Semiconductor recommends solder−on−pad (SoP)

surface finish. With SoP, the solder mask opening should be

non−solder mask−defined (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

then the following conditions must be met:

1. The solder mask opening should be >0.3 mm in

diameter

2. The copper pad should have a diameter of

0.25 mm

3. Solder mask thickness should be less than 1 mil

thick above the copper surface

For PCB manufacture with the 26−ball WLCSP version of

BelaSigna R262, any vias that might be placed below the

WLCSP should all be covered in soldermask. The assembly

process can use underfill under the WLCSP; it will provide

another physical dielectric barrier, and will also enhance

long term reliability over temperature and physical shock.

ON Semiconductor can provide BelaSigna R262

mounting footprint guidelines to assist your PCB design

upon request.
