A kind of electroplating tin treatment process

Abstract

The invention belongs to the technical field of electrotin plating treatment, and specifically relates to an electrotin plating treatment process. The oiling device used in the process includes an oil pool, the inner cavity of the oil pool is fixed with a mounting plate, and the side wall of the mounting plate rotates A rotating shaft is installed, the rotating shaft runs through the mounting plate, a driving motor is fixed on the side wall of the mounting plate, the output shaft of the driving motor is fixedly connected to the rotating shaft, and a number plate is fixed on the side of the mounting plate away from the driving motor, The end of the rotating shaft far away from the No. 1 disc is rotatably connected to the No. 2 disc, and a connecting rod is installed on the side wall of the No. 2 disc to rotate equidistantly along its circumference, and the end of the connecting rod far away from the No. 2 disc is fixed with a mounting disc. The present invention makes the oiling work of the pot-shaped workpiece simple by the setting of the oiling device, and automatically pours out the antirust oil inside the workpiece after the workpiece is taken out of the antirust oil, and drains the antirust oil in the workpiece during the rotation process. The anti-rust oil brought out by it reduces the waste of anti-rust oil.

Description

technical field [0001] The invention belongs to the technical field of tin electroplating, in particular to a tin electroplating process. Background technique [0002] Tin coating has been widely used in the electronics industry as a protective and solderable coating for electronic components, wires, printed circuit boards and integrated circuit blocks due to its excellent corrosion resistance and solderability. [0003] The application of electroplating tin is very extensive. Tin has the advantages of corrosion resistance, discoloration resistance, non-toxicity, easy brazing, softness, low melting point and good ductility. Dense, uniform and continuous alloy coating. [0004] Although the electroplating tin solutions are different, the electroplating process is basically the same. The basic process is divided into pretreatment, electroplating, reflow, passivation and antirust oil coating; Due to the special shape of the pot-shaped workpiece when using rust oil, a large am...

[0004] Although the electroplating tin solutions are different, the electroplating process is basically the same. The basic process is divided into pretreatment, electroplating, reflow, passivation and antirust oil coating; Due to the special shape of the pot-shaped workpiece when using rust oil, a large amount of anti-rust oil will be brought out after being directly immersed in the anti-rust oil, resulting in waste of anti-rust oil, and it is necessary to manually immerse the workpiece in the anti-rust oil, which may easily cause leakage of the workpiece. Coating, thereby affecting the service life of the workpiece, accordingly, the present invention proposes an electroplating tin treatment process
