About The Position

The Packaging Engineer position requires handling all aspects of packaging development. This means planning, crafting, and developing advanced or novel packaging. The role also involves managing packaging efforts related to radio frequency communication devices. The products range from IC’s, System In Packages, sub-assemblies, and modules. The packaging development process includes package definition, stack-up, substrate layout, bond diagram, drawings, predictive modeling combined with system testing, technical risk/cost assessment, materials and process characterization, compilation of formal documentation, collaborating with sub-contractors and internal assembly and reliability resources, and final release of product.

Bachelor's Degree in Electrical, Mechanical, Materials Engineering or related technical discipline
Deep understanding of micro-electronic package structure, mechanical, electrical and thermal performance.
Solid grasp of heat transfer and its relation to material properties
Packaging knowledge in RFIC, millimeterware, System In Package, sub-assembly, and/or modules.
Experience in semiconductor package design with demonstrated experience in one or more of the following: QFN, SiP, BGA, WL-CSP, Flip Chip and Bumping or FO-WLP
Strong understanding of Die Prep, Assembly (die attach, Wirebond, flip chip, etc) and Surface Mount Technology (SMT) process-equipment is desired.
Have a high tolerance for ambiguity and solid interpersonal skills
In-depth knowledge of interconnect reliability daisy chain testing, CPI and BLR.
Understands the metallization schemes for laminates, interposers and SMT.
Knowledge of statistical methods and Building of Experiments
Must be able to work autonomously and help determine methods and procedures.
Customer service oriented.
Ability to work with build teams to translate IC/system requirements input packaging configurations
Ability to manage and drive packaging
US Government position. US Citizenship required
Ability to travel up to 10%
