Abstract

The invention discloses printed circuit board tin spraying post-processing assembly line equipment which comprises a transportation base, the transportation base and the front portion of the right end of a fixing plate are fixedly connected with a correcting device, the rear portion of the upper end of a cleaning box is fixedly connected with a spraying device, and the front end of a stabilizing plate is fixedly connected with a driving device. A drying box is fixedly connected to the left portion of the upper end of the conveying base, an air heater is fixedly connected to the middle of the upper end of the drying box in a penetrating mode, a perspective window is fixedly connected to the left end of the drying box, a plurality of heating rods are jointly and fixedly connected between the front box wall and the rear box wall of the drying box, and a control panel is fixedly connected to the front end of a material receiving frame. According to the tin-spraying post-processing assembly line equipment for the printed circuit board, the whole equipment is reasonable in structural design, a multi-stage cleaning mode is adopted, the cleaning effect is good, the drying speed is high, the structure is stable, use of the tin-spraying post-processing assembly line equipment for the printed circuit board is facilitated, and the tin-spraying post-processing assembly line equipment for the printed circuit board is suitable for wide application.

Description

technical field [0001] The invention relates to the technical field of printed circuit board processing, in particular to an assembly line equipment for post-tin spraying of printed circuit boards. Background technique [0002] For general printed circuit boards, the tin spray process includes pre-processing and post-processing. The general pre-processing process includes: placing the board - lightly scrubbing the board - pressurized water washing - micro-etching - overflow water washing - ultrasonic water washing - pressurized water washing - strong wind The main purpose of the pre-treatment process is to prepare for the tin spraying process, remove impurities on a printed circuit board and attach flux. The inventor found that there are at least the following in the prior art The problem has not been solved: 1. During the manufacturing process of the printed circuit board, the dust, residues, etc. remaining on the printed circuit board will affect the quality of the printed...

Problems solved by technology

[0002] For general printed circuit boards, the HASL process includes pre-processing and post-processing. The general pre-processing process includes: put the board - lightly scrub the board - pressurized water washing - micro-etching - overflow water washing - ultrasonic water washing - pressurized water washing - strong wind Blow-drying-inspection-roller rosin, the main purpose of the pre-treatment process is to prepare for the tin spraying process, remove impurities on a printed circuit board and attach flux. The inventor found that there are at least the following in the prior art The problems have not been solved: 1. During the manufacturing process of printed circuit boards, the dust and residue left on the printed circuit boards will affect the quality of printed circuit boards; 2. The cleaning process and equipment of the existing cleaning equipment are more complicated , the cleaning efficiency is often low, and the cleaning effect is not good; 3. The existing printed circuit boards are easy to shift during the transportation process, which is not convenient for the use of assembly line equipment; therefore, we propose a post-spray tin treatment of printed circuit boards Assembly line equipment
