PCB Design Guidelines
The recommended ACPM-7821 PCB Land pattern is
shown in Figure 14 and Figure 15. The substrate is
coated with solder mask between the I/O and con-
ductive paddle to protect the gold pads from short
circuit that is caused by solder bleeding/bridging.
Stencil Design Guidelines
A properly designed solder screen or stencil is
required to ensure optimum amount of solder paste
is deposited onto the PCB pads.
The recommended stencil layout is shown in Figure
16. Reducing the stencil opening can potentially
generate more voids. On the other hand, stencil open-
ings larger than 100% will lead to excessive solder
paste smear or bridging across the I/O pads or
conductive paddle to adjacent I/O pads. Considering
the fact that solder paste thickness will directly affect
the quality of the solder joint, a good choice is to use
laser cut stencil composed of 0.100 mm (4 mils) or
0.127 mm (5 mils) thick stainless steel which is capable
of producing the required fine stencil outline.
