SuZhou Tonkida Electromechanical Technology Co., Ltd Professional SMT whole line supplier

(1) Cleaning of the placement machine

The waste water after the product cleaning in the production process brings pollution to the water quality, the land and even animals and plants. In addition to water cleaning, organic solvents containing chlorofluorocarbons (CFC&HCFC) are used for cleaning, which also pollutes and destroys the air and atmosphere of the LED chip machine. The residue of cleaning agent will cause corrosion on the machine board and seriously affect the quality of the product. Reduce cleaning operation and machine maintenance costs. No cleaning reduces the damage caused by PCBA during movement and cleaning. There are still some components that cannot be cleaned. The residual amount of flux has been controlled, and the patch function can be used according to the appearance requirements of the product to avoid the problem of visual inspection of the cleaning status.

(2) The operating environment of the SMT machine

All kinds of indicators, buttons, operation handle appearance complete, operation, display normal; The computer system works properly; The input and output system works properly.

The equipment requirements for the operation site voltage should be stable, to prevent electromagnetic interference, to prevent static electricity, to have good lighting and exhaust gas emission facilities, the temperature, humidity, air cleanliness of the operating environment have special requirements, the operator should also go through professional technical training.

(3) Mounting accuracy of the placement machine

That is, the offset between the center of the component and the center line of the corresponding welding pad does not exceed 1/3 of the width of the welding foot of the component (visual inspection); Or the incidence of abnormal migration is not more than 3‰.

The appearance of the instrument and instrument is intact, the indication is accurate, the reading is eye-catching, and it is within the qualified service period; The equipment inside and outside regular maintenance, keep clean, no oil, no rust, the surrounding spare parts are arranged in order, the equipment is well lubricated.
