Product Overview
The AT-GDP Series BGA Rework Systems are semi-automatic machines featuring the latest vision and process control technologies. Lead-Free applications consisting of complex components such as BGA’s, CSP’s, QFN’s, Flip Chips, and other SMD’s are reworked with ease and high quality results. Precise mechanics coupled with a comprehensive software package automates the device removal and installation processes.
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. Absents of mirrors in the optics system ensure a clear and distortion free image quality. Precise closed loop reflow process control enables mimicking 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. Settings can be adjusted on-the-fly while the profile is running. Software controls reflow via forced air / nitrogen convection top heater, forced air convection localized bottom heater, and a large area Quartz IR preheater. Airflow at the top heater is monitored by the software as well and delivers unsurpassed temperature uniformity. This guarantees very gentle flow which cannot disturb even the smallest adjacent components. Controlled cooling of the part and PCB is accomplished via direct air / nitrogen flow at the top nozzle, air flow at the localized bottom heater, and large area underside board cooling.
Like other machines that our company has been producing for over the past 25 years, AT-GDP was designed to be very easy to use and capable of handling both today’s and tomorrow’s rework requirements. AT-GDP series offers unparalleled performance aimed at applications where precision and consistently high quality rework matters.

Operation
At the click of an icon, the system automatically places the component onto the PCB, shuts off the vacuum to the pick up tube, lifts the pick up nozzle away from the package body, executes a reflow profile, and raises the reflow head at the completion of a cycle. Removal features the same automation only now, the component is pulled off the board at the completion of a cycle.
Software
Profiles are developed, stored, and recalled in the AT-GDP’s software package. It controls the reflow cycle, automation of process sequences, and automatic execution of safety checks before every profile run.
- Real-Time process graphing
- Automatic Profile Generation
- Profile development with up to 5 thermocouples
- Library with predefined profiles
- On-The-Fly settings adjustment
- Real - time data recording for documentation and analysis
- Password Protected Access
- Unlimited profile storage

Nozzles
An assortment of standard reflow nozzles is available covering a wide variety of components being reworked. During reflow, a nozzle may be positioned on a PCB covering the component or it may be set slightly above the device. Refer to the table below listing the most common nozzle sizes.
Throughout the years, we have manufactured thousands of nozzles in various designs and dimensions. ATCO’s custom manufacturing capability allows us to design and fabricate a nozzle for even the most complex applications. Contact us regarding availability of custom made nozzles. Please indicate component dimensions or provide a mechanical package drawing.
