New AT-GDP Series BGA Rework Station Provides the Latest Precision and Process Control

Advanced Techniques US, Inc. (ATCO), a manufacturer of innovative equipment for assembly, soldering, and rework of printed circuit boards, is pleased to announce the development of an AT-GDP Series BGA Rework Station. Precise mechanics coupled with a comprehensive software package automates the device removal and installation processes. This model handles both leaded and lead-free applications consisting of components such as BGA’s, CSP’s, QFN’s, Flip Chips, and other SMD’s.

The AT-GDP’s rigid design enables ultra precise placement to within 5 microns. Split Vision Optics allows simultaneous top of the PCB / bottom of the component viewing to superimpose and align both images. Split Imaging creates diagonal corner viewing for alignment of larger packages at high magnification. Absence of mirrors in the optics system ensures a clear and distortion free image quality. Precise closed loop reflow process control enables mimicking of the original production profile. Software contains a database of predefined profiles which the user selects based on the package and PCB being reworked. Profiles may be easily modified, optimized, and stored for future use. Program settings can be adjusted while the profile is running. Software controls reflow via forced air / nitrogen convection top heater and large area Quartz IR preheater. Airflow at the top heater is also controlled and monitored by the software. This guarantees very gentle flow which will not disturb even the smallest adjacent components.
