Refer to the following application notes for detailed guidelines and suggestions when implementing

iPOWIR Technology products:

AN-1028: Recommended Design, Integration and Rework Guidelines for International Rectifier’s

iPOWIR Technology BGA Packages

This paper discusses the assembly considerations that need to be taken when mounting iPOWIR BGA’s

on printed circuit boards. This includes soldering, pick and place, reflow, inspection, cleaning and

reworking recommendations.

AN-1029: Optimizing a PCB Layout for an iPOWIR Technology Design

This paper describes how to optimize the PCB layout design for both thermal and electrical performance.

This includes placement, routing, and via interconnect suggestions.

AN-1030: Applying iPOWIR Products in Your Thermal Environment

This paper explains how to use the Power Loss and SOA curves in the data sheet to validate if the

operating conditions and thermal environment are within the Safe Operating Area of the iPOWIR product.

AN-1047: Graphical solution to two branch heatsinking Safe Operating Area

This paper is a suppliment to AN-1030 and explains how to use the double side Power Loss and SOA

curves in the data sheet to validate if the operating conditions and thermal environment are within the Safe

Operating Area of the iPOWIR product.
