Lead Free Powder
Qualitek manufactures electronic grade solder powders that are available in Type 2 (75-45mm), 3 (45-25mm), 4 (38-20mm), and 5 (25-15mm) J-STD-005 powder distribution. Solder powder distribution is measured utilizing laser diffraction, optical analysis and sieve analysis. Careful control of solder powder manufacturing processes ensures the particle shape is 95% spherical minimum (aspect ratio<1.5) and the powder contains a typical maximum oxide level of 80ppm.
