What is the reason why the PE film cannot be sucked on the PCB board vacuum machine?


One of the most important packaging methods for PCB boards is vacuum circuit board packaging or vacuum tight protection packaging for circuit boards. What is the reason why the PE film of the PCB board vacuum machine cannot be sucked during use? The vacuum packaging machine of the circuit board is not tightly evacuated, and the vacuum packaging film of the circuit board cannot stick to the bubble film. What is the reason? How to deal with it? Today, Fengyuan Packaging Information Department will make a detailed explanation.

 

Circuit board vacuum packaging machine does not vacuum

 

Let's first understand the process and principle of vacuum packaging of PCB circuit boards: Through the heating system of the circuit board vacuum skin packaging machine, the vacuum packaging film is heated and softened, and then it is covered on the circuit board and the transparent bubble bottom film. The vacuum suction force of the PCB body vacuum packaging machine is activated under the base film, and the vacuum tight protective packaging film is shaped according to the shape of the circuit board, and is tightly adhered to the bubble base film. Between the transparent top film and the bottom film, it has excellent visual display effect and the effect of industrial shock-proof protective packaging.

 

The first possible reason that the PE film of the PCB board vacuum machine cannot suck: If the three-phase power supply is used, the phase sequence may be reversed, and the vacuum pump is reversed. If the vacuum pump turns to a particularly loud sound, it is the vacuum pump. To reverse, you need to reverse the wiring of two of any three live wires.

 

Circuit board vacuum packaging machine is not tightly vacuumed. The second possible reason: the bubble film is inverted. The bubble film side should be placed upwards. If the flat side is in contact with the vacuum membrane, the vacuum cannot be eliminated, so the vacuum cannot be evacuated.

 

The third reason that the vacuum packaging film of the circuit board cannot stick to the bubble film is that the vacuum pump is broken or the vacuum tube is loose. This inspection can be replaced or repaired.

 

What is the reason why the PE film cannot be sucked on the PCB board vacuum machine?

 

The circuit board adopts a vacuum body or a vacuum tight protection package. The main purpose is to achieve the effect of vacuum moisture and oxidation prevention. Therefore, the vacuum degree of PCB vacuum skin packaging products is not high, which is very critical. In fact, this question and answer method are also useful for the vacuum skin packaging of other products, such as packaging circuit boards, magnetic cores and other electronic accessories, brake pads, bearing pads, radiators and other auto and motorcycle accessories, saw blade drills, and other tool hardware. , Furniture decoration hardware, lighting hardware, cold fresh seafood, salmon and other seafood.

 

About the vacuum of the circuit board vacuum packaging machine is not tight, the vacuum packaging film of the circuit board can not stick to the bubble film, the PCB board vacuum machine can not suck the PE film.
