Chip in QFN Package
5

Here's an old test chip (Direct Digital to Antenna chip) in a QFN package done in IBM 9HP (90nm SiGe BiCMOS). The WeMacro Controller, 4X Inf. 0.1NA lens, THK KR20 modified focus rail and Nikon 200mm F4 "Q" tube lens with D800E camera were used. Lighting came from 4 Adorama studio 300AC strobes with foam diffusers and subject was inside a white foam cup on base of a WeMacro Vertical Stand attached to a Ball Head with a pin glued to the QFN backside (removed in post).

A total of 157 images (50um steps) were collected at processed with Zerene.

Best,

Mike
