Abstract

The invention discloses a BGA rework station provided with an adjustable air outlet and relates to the field of integrated circuit maintenance equipment. The BGA rework station comprises the air outlet formed at a hot air nozzle, the hot air nozzle is sleeved with an adjusting case, and an opening with the size smaller than that of the air outlet is formed in the adjusting case; a rotary shaft isrotationally connected in the hot air nozzle, a first impeller is fixedly connected onto the rotary shaft, and two ends of the rotary shaft extend into the adjusting case; two ends of the rotary shaftare sleeved with centrifugal fans, each centrifugal fan comprises a suction port and an output port, a through hole is also formed in one side, where the opening is formed, of the adjusting case, anair outlet is formed in one side, away from the opening, of the adjusting case, a delivery pipeline and an exhaust pipeline are arranged in the adjusting case, the through hole and the suction port are communicated through the delivery pipeline, and the output port and the air outlet are communicated with the exhaust pipeline. The problems that the size of air outlets of existing BGA rework station cannot be adjusted and air blown out by the air outlets diffuse all around to affect BGA chips not needing desoldering are solved, and the BGA rework station is mainly applied to dismounting and welding in the BGA chip rework process.

Description

technical field [0001] The invention relates to the field of integrated circuit board repair equipment, in particular to a BGA repair station with an adjustable air outlet. 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 multi-pin, large information processing capacity, small chip size, etc., and have been widely used in the field of digital communication (such as mobile phones, IPTV, handheld security communication equipment, etc.). At present, the welding technology of BGA chips has become an essential key technology in the assembly of printed circuit boards. The BGA rework station is an intelligent operation device for visual alignment, welding and disassembly o...
