●I.Description and Purpose:
■The purpose of this PCN is to notify customer of the implementation of a new AC013 dispensing material (barrier gel) that is being used on the package of the TMF8801/TMF8701 products.
●II. Scope and Limitation
■This PCN document applies to TMF8801 and TMF870l.
●III. Background:
■This is a part of the continuous improvement program (CIP) at assembly to address final test
yield issue and risk of low defect rate problem that customer may encounter at their production line.
■Subsequent experiments done by ams AG determined that failures might occur when the parts are subjected to high temperature reflow. Based on failure mechanism, the current dispensing material (barrier gel) AB025 has fillers that can induced mechanical damages on the die surface when the product goes through solder reflow.
■ams AG then investigated a potential improvement and found that the introduction of the new dispensing material (barrier gel) AC013 will completely prevent the mechanical damage encountered by the current dispensing material.
