Q-Pearl Leaded & Lead Free BGA Solder Spheres
Qualitek manufactures Q-Pearls using a new technology that assures exact alloy composition, consistent and accurate diameters and highly spherical shapes of the spheres.
All spheres are made from pure metals combines 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 ina 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.
