Alpha Introduces Ultrafine Cored Wire for Fine-Pitch Component Soldering and Rework


Reading time ( words)

Alpha Assembly Solutions is introducing ALPHA SAC305 Ultrafine Cored Wire for use in attaching or repairing very fine pitch components approaching 0.20mm.

“With the increase of solder joint density and miniaturization, ALPHA SAC305 Ultrafine Cored Wire is an ideal solution where solder paste reflow or other soldering applications are not compatible to the design,” said Bernice Chung, Global Portfolio Manager for Wave Soldering at Alpha Assembly Solutions, a part of the MacDermid Performance Solutions Group of Businesses. “Fine pitch PCB assemblies have higher quality and reliability standards, which requires precise solder wire feeding volume and non-skip solder feeding. Ultrafine cored wire delivers consistent diameter size and flux continuity to ensure unfailing wire feeding, especially in robotic soldering, such as laser soldering technologies.”

ALPHA SAC305 Ultrafine Cored Wire offers fast soldering performance and has passed the most stringent reliability tests. It can be used for any customer who has previously approved larger diameter wire using ALPHA Telecore HF-850, Telecore XL-825 or Telecore Plus core fluxes. Provided in cored wire for convenient use, ALPHA SAC305 Ultrafine Cored Wire is available in 0.2mm, 0.15mm and 0.1mm to fit different process requirements.

While there may be new techniques and strategies, technologies, equipment, tools, and materials to employ and utilize, there is always one thing that will ensure the manufacturing/ assembly success of your product: communication. Communication between the designer and the assembler will help improve the manufacturability and assembly of the final product—even before the board design gets fabricated.
