Solder balling under passives

2017/2/2 13:13:44

Hi guys,

Problem: Mid chip solder balling.

Component affected: 0603 caps only

Defect is PCB specific (Meaning only one PCB is affected as the aperture is standard for that component).

As a containment I'll give a home plate design for the component but by standard we don't use home plate designs for 0603.

I'm seeing mid chip solder ball only at the location where there is a trace beneath the mask.

Any advice or suggestion for this peculiar case?
