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.Specifications

Technology Overview - Remove if multiple tools use the same technology/process
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.
