Experience

Nov. 2002- Jan. 2013 Lamination Process Engineer, Endicott Interconnect Technologies, Inc. Endicott, NY. Responsible for:

• The operation, calibration, optimization, troubleshoot, operator training and safety of hydraulic presses, cleanroom, edge trim and stamp ID processes.

• Product yield improvement (consumer, medical and defense industries), cost reduction, layup diagrams and lamination recipes.

• Raw materials (PTFE, RCC, Prepreg, CIC and copper foils) quality and tests (DSC, TMA, Rheology, adhesion, hardness and tensile).

• Achievements:

1. Eliminated the use of Invar release sheets resulted in 500k annually saving.

2. Developed test plans (adhesion, tensile, rheology and thermal (DSC & TMA) on critical raw materials to minimize product yield loss and reliability issues.

3. US Patent 7059049, Electronic package with optimized lamination process.

4. Developed, jointly with suppler, optimum processes for PTFE green sheets and surface treatment for copper foils to improve the adhesion between the two materials through DOE and results in better product yield and reliability.

5. Setup companywide FOD/FOE program to comply with medical and defense industries requirements when company first expanded into these industries.

6. Visited and worked with a single-sourced supplier in Japan to overcome production issues and avoided the potential disruption of production.

Nov. 1998 - Oct. 2002, Advisory Engineer, IBM, Endicott, NY

• Mechanical testing: Instron (static), MTS (dynamic) and Impact Testers.

• Melt Indexer, Tabor abrasion tester and UL Flammability Test.

• Manufacture support on Fracture/Failure Analysis and material characterization.

Jul 1984 – Oct. 1988, Plastic Engineer, IBM, Endicott, NY

Responsible for design verification, material selection, mold approval and failure analysis on injection molded plastic components in high speed printers and:

• Setup polymer material specifications.

• Setup Person Computer and train department member.

• Development of MOCA Free Polyurethane, jointly with University of Detroit.

• EMI shielding testing on plastic components.

Sep 1979 – May 1984, Research Assistant, Rutgers University. Research Projects include:
