ALPHA Vaculoy SAC305 Solder Bar

Harmonization Code : 8001.20 |   Unwrought tin: Tin alloys
Main features
  • Fast wetting
  • Excellent solderability
  • Very good drainage

Product Description

ALPHA SAC305 Solder Bar is a high-performance, lead-free alloy designed as a direct replacement for the industry-standard Sn63Pb37. It is the flagship of the SAC series (Tin-Silver-Copper), widely recognized for its excellent wetting characteristics and joint reliability in wave soldering and surface mount applications.

Product Key Features

  • Produced using the proprietary Vaculoy alloying process, which removes impurities—specifically oxides—to ensure low drossing and high-quality solder joints.
  • Fully lead-free and suitable for modern electronics manufacturing where environmental standards are a priority.
  • Fast wetting, in back to back tests 0.65s compared to 1.00s, for Sn/Cu-based materials
  • Excellent solderability due to fast wetting speed

Applications

  • Wave and selective soldering applications

Specific Heat Capacity
Specific Heat Capacity
Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass. The specific heat capacity of a material is a physical property. It is also an example of an extensive property since its value is proportional to the size of the system being examined.
