Industry information

Precision electronics industry plating line aeration / finished product blow-drying, permanent magnet frequency centrifugal blower applications are as follows

Inner layer pre-treatment

Need to chemically clean and de-grease the inner layer board to ensure the adhesion effect in the subsequent process and enhance the adhesion of the plating layer.

Etching

After the inner layer pre-treatment, chemical solutions are used to remove unwanted metal parts and form fine conductive patterns to ensure circuit integrity and conduction performance.

Press-Fit

Multiple layers of PCB boards are pressed together by high temperature and pressure to make each layer of the board a whole and to ensure that its internal wiring is connected tightly and stably.

Drilling

Drill holes in the pressed boards for electrical connection, to realize electrical conduction between different layers through copper pillars or other conductors.

Plating

After drilling the PCB board plated with a conductive metal layer, so that the hole wall to form a conductive path to improve the stability and conductivity of the circuit, and at the same time in the whole board to form a uniform conductive layer.

Process Flow

Pain point background

The plating line process in the precision electronics industry requires a high degree of product accuracy and reliability, but in the pursuit of efficient production and strict quality standards, enterprises are faced with a number of challenges. Especial

Pain Point 1

Traditional fixed-frequency blowers suffer from high energy consumption in plating lines. With no flexibility to adjust airflow output, they continue to consume power even during low demand, resulting in wasted energy. In addition, the low efficiency and poor energy utilization of conventional blowers results in higher overall operating costs. In long-time, high-frequency use, such as aeration and finished product blow-drying, constant-speed blowers make it difficult to accurately match airflow, resulting in poor process control and further increasing rework and reject rates, making them an industry pain point that needs to be addressed.

Solution

Project engineers after on-site investigation and analysis: 2 sets of Xinlei high-efficiency blower to replace the original 6 sets of scroll blower, used in the precision electronics industry horizontal blow-drying process. The actual operating power of Xinlei blower is only 9kW, which is significantly lower than the 25.8kW operating power of the original equipment. Thanks to the permanent magnet high-speed motor and advanced airflow control technology, the motor efficiency of Xinlei blower is more than 96%, which realizes significant energy saving effect, and the effective energy saving rate breaks through 65%, which not only saves the operation cost, but also pushes the enterprise to realize the transformation of green production.
