Low‑temperature soldering adopts low‑melting‑point alloy solders to substantially reduce peak soldering temperature. It avoids high‑temperature‑induced damages such as component failure, substrate warpage, plastic deformation and coating discoloration, while meeting assembly requirements for precision thermal‑sensitive components and ensuring finished‑product yield.

Industry Challenges & Solutions

Assembly of thin‑light boards, thermal‑sensitive components and flexible circuit boards is vulnerable to high‑temperature processes, which readily cause defects including board warpage, thermal damage to components and solder‑joint cracking. Conventional solders exhibit insufficient wettability at low temperatures and fail to satisfy production requirements.

Huaqing’s Sn‑Bi series low‑temperature solders combined with high‑activity low‑temperature fluxes achieve high‑quality wetting soldering under low‑temperature processes and reduce overall assembly thermal stress.
