Mechanic Features
ZM5202 is a 108-pin LGA encapsulation module. Except for the signal PIN, there
are many dedicated heat-dissipation ground wielding panel to improve the
grounding performance, mechanical strength and heat-dissipation performance.
There are altogether 30 heat-dissipation ground wielding panels, evenly distributed
at the bottom of PCB. The dimensions of 108-pin LGA encapsulation are 26*36mm,
and the height is 2.5+/-0.2mm. The location of PIN 1 is identified by the ground
wielding panel with an inclination at the bottom, and its angle orientates to the top
