Ball‑Mount is the core procedure for substrate ball mounting. Through solder‑ball placement and reflow forming, standard‑array solder balls are fabricated on substrate pads. It serves as a critical pre‑process for BGA and FCBGA packaging.

Well‑matched supporting solders enable stable control over solder‑ball roundness and array coplanarity, ensuring reliable subsequent SMT soldering.

Industry Challenges & Solutions

During reflow, conventional solder balls and matching flux materials are prone to solder‑ball offset, collapse and poor wettability. Mass production suffers inconsistent solder‑ball dimensions with high incidences of voids and cold‑solder‑joint defects.

Huaqing’s customized solder balls dedicated to ball‑mounting and supporting flux systems feature controllable melt flowability. The formed solder balls are regular and uniform with ultra‑low void rates. Compatible with high‑volume ball‑mounting production lines, they effectively boost finished‑product packaging yield.
