BGA Solder Spheres For Lead Free & Leaded Assembly

Qualitek manufactures Q-Pearls utilizing the latest technology that assures exact alloy composition, consistent accurate diameters and highly spherical shapes. All spheres are made from pure metals combined to provide required alloy composition according to J-STD-006 specification or customer specific. After forming the spheres are classified for size by a precise and non-abrasive sorting process. The diameters of the spheres are monitored and controlled within 0.001" +/- 0.0005" tolerance. Sphere size distribution is measured precisely by a sophisticated image analysis system connected to scanning Electron Microscope (SEM). To determine sphericity, sphere diameter is measured in 16 directions in a fraction of a second.

Sphere Size & Composition

Choosing the correct alloy and sphere size is based on the type of BGA package and the processing temperature of your assembly. Solder Spheres in Ball Grid Array packages are used to provide the electrical and mechanical connection between the component and the board assembly. Available in 50K vial. BGA Spheres may be purchased through your local distributor and online at the solderstoreonline.com | Product Brochure | BGA Sphere Technical Data & SDS |
