SemiPack Services has been providing BGA Conversion/ Modification to the Military, Aerospace/Avionics & Commercial market segments for well over 15 years. We have developed with the implementation of full robotics technology, superior proven processes for De-Balling/ Re-Balling Ball Grid Arrays (BGA’s).
SemiPack’s Ball Attach Process includes the Conversion to Leaded (63/37) spheres for those Hi-Rel applications, as well as the Conversion from Leaded (63/37), spheres to RoHS (SAC 305) spheres for more Commercial applications.
SemiPack’s automation removes the existing solder sphere and pad finish with our Odyssey RPS Robotic Technologies. This process, a non-contact operation, flushes the current Lead-Free solder spheres and surface residues from the pads and replaces them with Solder ( 63/37 ) Spheres. SemiPack has also implemented RPS Vector (Full Robotics) technology for processing the High Pin count BGA devices (25mm).
SemiPack’s automation provides for 100% removal and alignment/ attachment accuracy of the replacement solder spheres ensuring the most durable solder joints with perfect co-planarity. SemiPack’s Re-Balling /Modification on BGA’s (Ball Grid Arrays) are processed to customer specifications based on required solder sphere diameters. They are placed with custom-designed, hand-tooled stencils that afford perfect alignment. SemiPack’s Process Engineering reviews all customer & manufacturing datasheets to validate reflow requirements for each new component that requires a reflow profile.
After BGA reballing is complete, forced convection reflow, or rework, takes place. Forced convection reflow is a method used to solder components to a printed circuit board. The oven is typically separated into controlled zones, optimizing for thermal specifications. This process is controlled and maintains a low-component temperature to minimize its’ thermal gradient. Ovens are calibrated & thermally profiled.
