Storage & 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 surface by skin oils. Shelf life of all solder spheres, stored in sealed ESD containers that are not agitated, is one year.
