Introduction

A System-On-Module (SOM) is mounted on a motherboard in the same way as other SMT components by using a Pick & Place machine.

The Pick & Place machine, defined by the CAD placement file, often picks the SMT components by their center of gravity. Applying this rule to a SOM is not a reliable solution during the assembly phase because the module's center of gravity is not necessarily aspirable by the nozzle, as it may correspond to a position half on a component and half on the PCB.

This application note provides Pick & Place characteristics for Microchip SOM variants.
