Product Overview

The AT-GDP Series BGA / SMT Rework Stations feature the latest vision and thermal process control technologies. Circuit boards consisting of complex components such as BGA’s, CSP’s, QFN’s, Flip Chips, PoP, micro Dies, and many other SMD’s are processed delivering high quality results. Precise mechanics along with an advanced software package automates the device removal and installation. Machine automation limits operator involvement making these systems very easy to use. Automation and ease of use are both critical for prototype and low volume applications where success must be achieved on the first try.

Solid design enables ultra precise placement to within 5 microns. A newly implemented software driven Force Measurement System makes it possible to handle even the smallest and fragile devices along with complex packages like stacked dies or Package-On-Package (PoP). Split Vision Optics allows simultaneous top of the PCB / substrate and bottom of the component viewing to superimpose and align both images. Split Imaging is a feature that creates diagonal corner viewing for alignment of larger packages at high magnification. High quality components within the optics system ensure a clear and distortion free imaging. 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. An Automated Profile Generation feature allows the user to develop an optimum profile in a single pass that may be saved for future processing. 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 requirements. AT-GDP series offers unparalleled performance aimed at applications where precision and consistently high quality results matter. Ranging from R & D / Engineering departments to production environments typical of volume repair centers.

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.
