- Develop and maintain process documentation: print parameters, placement programs, reflow recipes, AOI criteria, work instructions.
- Lead DFM/DFX reviews with customers on flex stack-ups, stiffeners, coverlay, PSA details, and bend radii.
- Troubleshoot defects (tombstoning, HIP, voiding, opens/shorts, pad cratering) using SPC and DOE.
- Support NPI, ECNs, and transfers; mentor operators/techs; partner with QA on control plans and PPAPs.
Experience and Educational Requirements:
- A BS degree in Engineering preferred or 5+ years SMT process engineering in EMS/ODM/OEM environment.

- Hands-on experience with flex/rigid-flex builds (coverlay, stiffeners, connectors, bend rules).
- Strong reflow profiling skills for polyimide/flex assemblies.
- Proficiency with at least one in each area: Printers (MPM), Placers (Panasonic), Inspection (Omron), CAD/DFM (Altium/Allegro + CAM350/Valor).
Nice to Have:
- Experience with nano-coatings, step stencils, fine pitch (=0.4 mm BGA/WLCSP).
- Voiding control for QFN thermal pads on flex or hybrid substrates.
- IPC-A-610 / IPC-6013 familiarity; IATF 16949 / AS9100 exposure.
- Conformal coat/mask design for flexing zones.
Minimum Skills, Knowledge & Ability Requirements:
