Plasma surface treatment equipment PCB and polymer material surface treatment effect:
Plasma is formed by applying electric field to low-pressure gas for glow discharge, which can modify the surface energy of polymer materials such as PTFE. Plasma surface treatment equipment is widely used in PCB(printed circuit board) hole metallization pretreatment, polytetrafluoroethylene and other materials bonding pretreatment and PCB surface activation treatment.
It can replace the traditional sodium naphthalene solution immersion, and provides a fast, convenient and clean treatment method for the surface activation of PTFE and other substrates. The system software of plasma processing equipment mainly consists of PLC control program and computer monitoring software. When the system runs automatically, the operator sets the control parameters, and then presses the automatic button to enter the automatic control monitoring interface.
PLC can send all kinds of control commands, at the same time can collect all kinds of real-time data of PLC, to achieve the whole process of production monitoring. The plasma processing system also has the function of real-time alarm and historical data preservation. PLC software is used to realize all the control interface tasks of the equipment. Its design idea is based on saving the hardware investment as much as possible, replacing the hardware with software and improving the software efficiency for programming. PLC program powerful, flexible configuration, outstanding performance, including the bit logic counter timer, mathematical operation and other intelligent control module, can monitor the input state, change the output state, to achieve the purpose of control.
In practical application, the plasma processor system runs normally, the performance is stable and reliable, the interface is friendly, the user can simply monitor the process flow and parameter setting, and the efficiency is improved.
The plasma surface treatment equipment has obvious surface treatment effect on PCB and polymer materials, and can significantly improve the adhesion, hygroscopic and adsorptive properties of materials. Compared with the traditional control method, the plasma processor has the advantages of good real-time performance, simple operation, stable and reliable performance.
The design of plasma treatment system not only improves the production efficiency of PCB manufacturers and brings good economic benefits to enterprises, but also improves the automation level of the system to a great extent, which can provide reference for the design of other systems.
