The importance of adsorption dryer to PCB industry

Mounter, exposure machine, drilling machine, inspection machine isIn the PCB industry, there are several categories with large demand for gas. The reason why the use of pneumatic drill bit is accepted by most enterprises is that it has low energy consumption, fast response, and can reach the required pressure and speed in a short time. However, the pneumatic drill bit has a large amount of gas. If the compressed air does not meet the standard and the water content is too large, it will cause the drilling speed of the drilling machine to be unstable, damage the pneumatic components, and bring a greater impact on the position and speed control, resulting in poor product quality and increased defective rate. At the same time, the poor quality of compressed air will damage other production equipment and affect all production links.

The process of compressed air in the operation of the drilling machine is as follows: the compressed air after drying and filtering of the dryer is transported to the back cover through the pipeline.-Transporting to the front and rear Pelling and spindle housing via internal tracheal lines--There is a row of uniform air holes in the spindle shell and the inner wall of the front and rear Peilin. When compressed air enters, the compressed air blows up the axis to suspend it in the air.--When the coil passes through the variable frequency current, a magnetic field force is generated to make the shaft rotate at a rotating speed--The air compressor constantly replenishes the pressure loss to ensure the normal suspension of the axis (in this process, if the compressed air is not dry, a certain amount of water will be produced in direct contact with the product, and it will affect the normal operation of the spindle, resulting in defective products).

AccordingISO8573/1 standard (typical compressed air quality classification) and industry standards (JBT5967-2007Air medium quality grade for pneumatic components and systems),PCBThe basic requirements of compressed air quality in the industry are: water content-20 ℃(pressure dew point), dust0.1μmOil content0.1mg/m³. The pressure dew point is a measure of the quality of compressed air, for large gas consumption.PCBFor production, the average pressure dew point reaches-20 ℃In order to ensure the good product of the circuit board. However, in the current market,The quality of compressed air in the PCB industry is generally not up to standard, resulting in a high rate of defective products.

In summary, the compressed air quality is not up to standard.The hazards of the PCB industry are:1Damage to production equipment. Such as: electronic testing equipment, exposure machine, drilling machine, optical testing equipment, etc;2Directly affect the spindle drilling speed, the defective rate increases;3The quality of the compressed gas is not up to standard, and it is easy to cause pollution to the subsequent gas equipment, such as solenoid valves and cylinders.

of Joint Scientific and CreativeRegenerative adsorption dryer, high-efficiency precision filter and compressed air purification and deoiling equipment not only provide technical guarantee for completely solving the problems of water, oil and dust in compressed air, but also greatly reduce energy consumption compared with traditional purification equipment, greatly reducing the energy consumption and cost of enterprises.
