μModule Packaging, Assembly and Thermal Performance

The Linear Technology μModule™ solution combines integrated circuits and passive components in a single package. The μModule integrates several technologies to deliver a cost effective, advanced solution which maximizes board space and improves electrical and thermal performance.

The μModule is overmolded in a solid array and individual units are saw singulated. All μModule components are leadless with electrical connections being made through the land pad array.
