Senior Engineer, Test

Location: Dong Nai, Vietnam

DUTIES AND RESPONSIBILITIES:

1. Yield Improvement 

• Lead failure analysis on module test/cosmetic failures, including fails from production, qual, DMR units from module returns and RMA field returns. Root causes identified root, issue solved and corrective action implemented 
• Generate weekly yield report of module production test, failure modes analysis, coordinate supporting divisions reach yield target. 
• Coordinate OSA team to make design optimization well validated, qualified and executed smoothly for product yield/reliability improvement and cost down (2nd source, low cost design.) 
• Lead test correlation among module test, OSA test, in-process OSA data, optimize in-process specs for overall yield improvement. 

2. Scrap/cost Reduction 

• Improve First pass yield to reduce scrap, analyze module level Scrap, coordinate improvement actions to reduce module scrap. 
• Create debug tree. Debug MVT failed samples to identify design, assembly or test related issues. Feedback design/assembly/test related issues and resolving with respective teams. 
• Generate disposition guidance for module test failures by failure mode. Establish internal /cross site return rules w/ counter party w/ minimized rework cost. 

3. Product On time Delivery 

• Work closely with product engineers to collect yield data supporting HPU reduction from optimizations of test corners, test time, tuning algorithms… 
• Support module testers setup/debug/maintenance to ensure planned capacity for product on-time delivery.
