Abstract

The invention discloses a control system used for a ball grid array (BGA) repair platform. The control system used for the BGA repair platform comprises a controller, motors, a controlled device which is connected with the motors, a parameter setting and displaying unit and a temperature monitoring system, wherein the temperature monitoring system comprises a first warm area heater, a second warm area heater, a third warm area heater and a temperature detecting unit, the motors comprises a motor X, a motor Y, a motor Z and a motor W, the controlled device comprises a working platform which is connected with the motor X and the motor Y in a transmission mode, an optical alignment system which is connected with the motor W in a transmission mode, a sucker connected with the motor Z in a transmission mode and an image detecting device, and an actuator is connected with the controller and the motors. The control system used for the BGA repair platform is simple in structure and convenient to use and operate, can effectively resolve the defects that a traditional BGA repair platform is inaccurate in temperature control, imprecision in the matching of BGA chip pins and printed circuit board (PCB) welding disc images and low in intelligent degree, improves repair rate and production rate, and greatly reduces company production cost.

Description

technical field [0001] The invention relates to a control system, in particular to a control system for a BGA rework station. Background technique [0002] At present, in the electronic industry and other technical fields, the core technology of electronic products - the assembly technology of printed circuit boards is undergoing tremendous changes, supporting the transformation of electronic product component packaging to high-density packaging. BGA chips have the characteristics of multiple pins, large information processing capacity, and small chip size, and have been widely used in the field of digital communications (such as mobile phones, IPTV, handheld secure communication equipment, etc.). At present, the soldering technology of BGA chips has become an indispensable key technology in the assembly of printed circuit boards. The BGA rework station is the operating equipment for visual alignment, welding and disassembly of BGA components of different sizes. The curren...
