2024-12-20 to 2025-01-02: Reduced Holiday Operations

Dear Birck Research Community,

The Purdue winter recess begins effective Friday afternoon December 20th and concludes Thursday morning, January 2. The university is officially closed during this time. As we have done in past years, the Birck Nanotechnology Center will remain available for research but will be unstaffed and hazardous gasses will be unavailable. Lab work may otherwise proceed, though any fume hood work must be done with someone else present in the same laboratory or cleanroom bay (the "buddy" system). Click the link above to get more detail about equipment conditions and rules.

Overview

General Description

This precision tool welds gold wire from chip pad to package. The pad surfaces to be bonded must be compatible with gold or the bonds will not stick. Gold, copper, anuminum, or silver work well. Titanium, ITO, and diamond can not be wire bonded

Specifications

The JFP WB-100 is a general purpose wire bonder. It is capable of ball, wedge, and ribbon bonding, HOWEVER the changeover from one mode to another is non-trivial, therefore it is usually set up for ball bonding with 1 mil (25 micron) gold wire.

Technology Overview

Sample Requirements and Preparation

No special sample cleaning is required prior to wire bonding. Sample metallization must be thick enough to withstand the rigors of bonding. Samples must be securely mounted in their respective packages, and the package must be securely mounted to the bonding fixture. Double-sided cellophane tape is not an acceptable mounting technique.
