Wafer-level Packaging Equipment Manufacturer, Yield Engineering Systems, Inc. (YES), Releases New Whitepaper


Livermore, California (EastBayDaily) — Yield Engineering Systems, Inc. (YES), a wafer-level packaging (WLP) process equipment manufacturer, announced today that they have written a new whitepaper discussing the importance of using a polyimide vacuum curing system instead of an atmospheric oven for successful Redistribution Layers (RDL). It was recently featured on Semiconductor Packaging News. The full whitepaper can be obtained online at http://www.yieldengineering.com/wlp.

“Superior Polymer Processing for Wafer-level Packaging” explains that an integral part of WLP involves the relocation of the Input/Output (I/O) pads used to communicate with the die to points suitable for the final package. The pads can be relocated using RDL.

YES manufactures a variety of equipment including tools for WLP type processes with a low-cost of ownership. The YES-VertaCure Series and the YES-450PB Series use high temperature to achieve wafer dehydration, oxygen removal and solvent outgassing. These processes are vital to the success of wafer-level packaging.

“YES equipment significantly streamlines the WLP process,” says Bill Moffat, CEO and Founder, “We understand engineer’s WLP issues and have created a viable solution.”
