Product Overview
The AT-707 series BGA Rework Stations are semiautomatic machines featuring spilt vision optics and precise software process control. Systems are used to rework various devices such as BGA’s, CSP’s, QFN’s, QFP’s, and other complex SMD’s in both Lead-Free and Eutectic applications. High level of automation limits operator involvement making these machines very easy to use. As well as, provides high quality results that are consistent from one board to the next.
Split vision optics allows simultaneous top of the PCB / bottom of the component viewing to superimpose and align images (using X, Y and Theta micrometer adjustments). A Split Imaging Device creates diagonal corner viewing for alignment of larger packages at high magnification. It is also critical in viewing the walls of the nozzle in relation to the PCB to ensure that adjacent components will not be interrupted during reflow. Adjustable placement pressure ensures complete control in rework of various package types. Closed loop reflow process control enables mimicking the original production profile. The comprehensive software package easily allows modifying and optimizing reflow profiles with an on-the-fly settings adjustment capability. It also controls airflow, top and bottom forced convection heaters, and automation of process sequences. Precisely controlled cooling via compressed air / nitrogen plays a critical role in achieving high quality joint.
Unique machine design based on a truly semi-automatic platform enables repeatable process control and accuracy. AT-707 series offer unparalleled performance, ease of use, and an exceptional value making them superior systems heads above the competition.

Operation
At the click of an icon, the system automatically places the component onto a 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 reflow.
Software
Profiles are developed, stored, and recalled in the AT-707’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
- Profile development with up to 4 thermocouples
- Library with predefined profiles
- On-The-Fly settings adjustment
- Real - time data recording fordocumentation and analysis
- Password Protected Access
- Unlimited profile storage
- User friendly environment
- Designed for Windows® XP / Vista OS

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.
