Semiconductor Packaging Case Studies | Zhanyang

Founded in 1998, Zhanyang Precision specializes in the design and manufacturing of precision semiconductor components, fixtures, molds, and wafer process carriers. Serving advanced packaging applications including CoWoS, SoIC, FOPLP, Die Saw, Die Bond, and Wire Bond, we integrate ultra-precision machining, advanced material processing, nano-coating, and mirror polishing to deliver high-performance solutions. With expertise in ceramics, quartz, tungsten carbide, copper, and specialty alloys, Zhanyang helps customers improve yield, process stability, and manufacturing efficiency. Case studies document a hybrid tungsten carbide and stainless steel ejector pin design, a CM700 multi-stage ejection upgrade, localized CoWoS and SoIC bond tool manufacturing, and a tray conversion fixture with ESD and poka-yoke protection.

Yield and Stability Problems Solved on Packaging Lines

Four documented projects show the pattern: a hybrid tungsten carbide and stainless steel ejector pin assembly, ground to a flatness below 2 μm and surface roughness below Ra 0.65 μm, lifted die pick yield above 99% on ultra-thin die; a CM700 die bonder was converted from single-stage to multi-stage ejection with cam profile optimization so stress is released gradually on high-aspect-ratio die.

The other two address supply and handling. Bond tools for CoWoS and SoIC were localized to Taiwan manufacturing in M390 tool steel and aluminium nitride ceramic, removing import lead time from the critical path; a material box conversion fixture with ESD protection and slot-matched poka-yoke positioning eliminated collision and misload damage before plasma cleaning.
