• (1) Circuit traces from NSMD defined PWB lands should be 75 μ m to 100 μ m wide in the exposed area inside the solder mask opening. Wider trace widths reduce device stand off and impact reliability.
• (2) Best reliability results are achieved when the PWB laminate glass transition temperature is above the operating the range of the intended application.
• (3) Recommend solder paste is Type 3 or Type 4.
• (4) For a PWB using a Ni/Au surface finish, the gold thickness should be less 0.5 mm to avoid a reduction in thermal fatigue performance.
• (5) Solder mask thickness should be less than 20 μ m on top of the copper circuit pattern
• (6) Best solder stencil performance is achieved using laser cut stencils with electro polishing. Use of chemically etched stencils results in inferior solder paste volume control.
• (7) Trace routing away from DSBGA device should be balanced in X and Y directions to avoid unintentional component movement due to solder wetting forces.
