Product Data Sheet
BGA Solder Spheres
Product Description
Amtech's BGA Solder Spheres are manufactured from virgin materials to meet or exceed the requirements of building
or repairing BGA packages. AMTECH spheres also exceed both IPC and MIL standards for purity levels and size
tolerances. Normal sizes are from 3 mil to 35 mil and custom solder sphere sizes are available upon request.
Other alloys are available upon request.

Storage and Handling Procedures
Clean and dry environments are required for storage of solder spheres. Probing of solder spheres in containers with
fingers or other implements can damage the solder spheres by changing the shape, scoring the surface or
contaminating the suface by skin oils. Shelf life of all solder spheres, stored in sealed ESD containers that are not
agitated, is one year.
Packaging
35mil are packed in 150k bottles.
30mil - 8mil are packaged in 250k bottles and 6mil-4mil are packaged in 1kk bottles.
