Recommended Dimensions for the User System Mounting Pad
(Footprint)
Figure 6 shows the recommended dimensions for the mounting pad (footprint) for the user system
with the IC socket for a PLQP0120LA-A package (NQPACK120SE-ND: manufactured by Tokyo
Eletech Corporation). The dimensions in figure 6 are somewhat different from those of the mounting
pad for the system with the actual MCU. Also, note the user system can not be connected to the user
system interface board with inserting the guide pins in place.
