At present, the Vacuum Skin Packaging in China is almost the same; the main difference is only the effective working area and the degree of automation.
Preparation: PE film on the location, manual operation of mechanical action is normal, set the PE film heating temperature, vacuum time, etc.
When the number of laminated boards is fixed, their height is fixed. At this point, we must consider how to pile up to maximize the output and save the most materials. Here are a few principles.
The gauge of PE film (thickness), (standard is 0.2m/m) is regarded as the spacing of each laminated plate. By using the principle of heating and lengthening, the coated plate adheres to the bubble cloth while absorbing vacuum. The spacing is generally at least twice the thickness of the total plate. Too big is a waste of material; too small is difficult to cut and easy to fall off or not stick to at all.
If the PANEL size is not large, according to the above packaging, it will waste material and manpower. If the quantity is very large, it can also be similar to the soft-plate packaging mode to make containers, and then it does PE film shrink packaging. There is another method which need to the approval of the customer. There is no space between each laminated board, but it is separated by cardboard with the appropriate number of laminates. There are also paper or corrugated paper underneath.(proto pcb boards)
