PCB Board Packaging Process (2)

Second, vacuum skin packaging.

Operating procedures:

1. Preparation:

Position the PE film, manually operate whether each mechanical action is normal, set the PE film heating temperature, vacuum time, etc.

2. Stacking board:

When the number of stacked boards is fixed, the height is also fixed. At this time, you must consider how to stack it to maximize the output and save the material. The following are several principles:

a. The distance between each stack of boards depends on the specifications (thickness) and (standard 0.2m/m) of the PE film. Using the principle of being softened and elongated by heating, while sucking the vacuum, the coated board is pasted with the bubble cloth . The spacing is generally at least twice the total thickness of each stack. If it is too large, material will be wasted. If it is too small, it will be more difficult to cut and the sticking part will fall off easily or it will not stick at all.

b. The distance between the outermost board and the edge must also be at least twice the thickness of the board.

c. If the panel size is not large, according to the above-mentioned packaging method, materials and manpower will be wasted. If the quantity is very large, it can also be molded into containers similar to soft board packaging, and then PE film shrink packaging. There is another way, but it must be agreed by the customer to leave no gaps between each stack of boards, but separate them with cardboard, and take the appropriate number of stacks. There are also hard paper or corrugated paper underneath.

3. Start:

A. Press start, the heated PE film will be led down by the pressure frame to cover the table. B. The bottom vacuum pump will suck in air and stick to the circuit board, and stick it with the bubble cloth. C. Raise the outer frame after the heater is removed to cool it. D. After the PE film is cut, the chassis can be opened to separate each stack.

4. Packing:

If the customer designates the packing method, it must be in accordance with the customer’s packing specification. If the customer does not designate, the factory packing specification must be established on the principle of protecting the board from external damage during the transportation process. Matters needing attention , as mentioned earlier, especially the packing of exported products must be paid special attention.

5. Other Matters Needing Attention:

a. Information that must be written outside the box, such as “mark”, material number (P/N), version, period, quantity, important information, etc. And the words Made in China(if export).

b. Attach relevant quality certificates, such as slices, weldability reports, test records, and various customer-required test reports, and place them in the manner specified by the customer.

PCB board packaging is not a complicated matter. We only need to do every detail packing work carefully, so as to effectively avoid unnecessary troubles in the later stage.
