Working principle of vacuum press
2021-01-18 16:35
vacuum pressIt is a mechanical equipment for pressing multi-layer substances under vacuum conditions. No matter what kind of operation the vacuum laminating machine is applied to, its working principle is the same, that is, a certain pressure is applied to the surface of the multi-layer substance, and these substances are tightly pressed together. The different things are different according to the purpose of lamination, and the pressing conditions are different.
vacuum pressIt is composed of vacuum hot press, oil barrel of oil press unit, hot kerosene circulating heating temperature control system of this machine, control box of operation table, computer diagram control software, vacuum system, electric heater, cold press, bearing plate cover plate and installation and commissioning. It is a sheet material made of prepreg (glass cloth impregnated with epoxy resin and dried off solvent, under the action of temperature and pressure, it has fluidity and can quickly cure and complete bonding), a machine that bonds copper foil under vacuum, high temperature, and high pressure.
vacuum pressWorking principle
Whenvacuum pressAfter the power is turned on, the upper and lower heating plates of the machine start to heat up, and the vacuum system starts to work at the same time, making the space in the working area close to the vacuum state, ensuring that all the air between the pressing material and the material is discharged. When the temperature reaches the melting temperature of the prepreg, the prepreg will melt and fit closely with the copper foil, fully meet the requirements of the product and eliminate the stress in the middle of the material. If you want to make a multilayer board, you can make an inner layer board according to the above requirements, and add a semi-cured sheet and copper foil to complete. The role of the semi-cured sheet is To play the role of insulation and reinforcement.
For example, the motherboard of a computer is an example. For other 6-layer boards and 8-layer boards, the principle, process and method are the same as above.
- Enter the correct procedure, board length, board width, and board number as per the engineering specifications.
- Check whether the temperature, oil pressure, cold pressing pressure and time are set correctly.
- After confirming the temperature of the hot plate, the steel plate to be pressed is fed into the press.
- Check the pressure setting value, pressure actual value, temperature setting value, temperature actual value, vacuum setting value and actual value after the hot pressing rises.
- After the hot pressing is complete, the hot plate is automatically lowered, the steel plate is taken out and sent to the cold press, and cold pressing is started.
- After the cold pressing is complete, the pressing operation will be completed when the pressure plate automatically descends.
