An air energy bga soldering station heating base

Abstract

The invention relates to a heating base of an air-energy BGA (Ball Grid Array) soldering station. The heating base comprises a base body, a base bottom plate and a hot air gun. The heating base further comprises multiple semiconductor refrigeration sheets and multiple heat-conducting copper plates, wherein a first layer on the base bottom plate is a semiconductor refrigeration sheet, the rest heat-conducting copper plates and semiconductor refrigeration sheets are superposed on the first layer of semiconductor refrigeration sheet in a staggered manner, the uppermost layer is a heat-conducting copper plate, the cold ends of the semiconductor refrigeration sheets of all layers are downward consistently, and the hot air gun is mounted above the heat-conducting copper plate of the uppermost layer. A circuit board to be soldered is located above the hot air gun. According to the heating base of the air-energy BGA soldering station, the semiconductor refrigeration sheets are used for absorbing part of heat from surrounding air, the air is preheated and then is heated to working temperature of a chip soldering area by an air blower so as to heat the circuit board, and the heat-absorbed cooled air is used for cooling components and parts in a circuit, so that the service lives of the components and parts are prolonged, and the aims of lowering power consumption and reducing waste heat discharge are achieved.

Description

technical field [0001] The invention relates to a heating base of a BGA soldering station, which is the main part of the BGA soldering station. The BGA soldering station is generally also called the BGA rework station. It is a special equipment used when the BGA chip has soldering problems or needs to be replaced with a new BGA chip. It is used to heat the circuit board to a suitable temperature (about 180 degrees). Background technique [0002] BGA (Ball Grid Array, solder ball array package) rework station is a professional tool for repairing faulty BGA components. The mainstream heating methods in the world include full infrared, full hot air, and two hot air and one infrared. At present, these heating methods have their own advantages. The heating method of domestic BGA rework stations is generally upper and lower hot air, and three temperature zones for infrared preheating at the bottom (BGA rework stations with two temperature zones only have upper hot air and bottom ...
