Thaisarco alloyed solder powders are available in type 2, type 3 and type 4 grades. The particle size distributions meet or exceed the J-STD-006 specification shown below table. Other particle size distributions can be provided to meet individual customer's requirements.

Grade 1% Less Than 90% 10% Max.
Type 2 +75 microns 75-45 microns 45 microns
Type 3 +45 microns 45-25 microns 25 microns
Type 4 +38 microns 38-20 microns 20 microns
Type 4 < 120 ppm microns

Storage and Shelf Life

Thaisarco solder powders are packaged to ensure protection from air and moisture. Care must be taken to minimize air and high temperature exposure after opening the package.
