An ciorcad is no better than other products, and it cannot be in contact with air and water. First of all, the PCB board cannot be damaged by vacuum. A layer of bubble film must be placed on the side of the box when packing. The bubble film has better water absorption, which plays a very good role in preventing moisture. Of course, moisture-proof beads are also indispensable. Then classify them and place them on labels. After sealing, the box must be stored in a dry and ventilated place with partition walls and off the ground, and avoid sunlight. The temperature of the warehouse is best controlled at 23±3℃, 55±10%RH. Under such conditions, PCB boards with surface treatments such as immersion gold, electro-gold, spray tin, and silver plating can generally be stored for 6 months. 3 PCB boards with surface treatment such as tin sink and OSP can generally be stored.

1. Must be vacuum packed

2. The number of boards per stack is limited according to the size is too small

3. The specifications of the tightness of each stack of PE film coating and the regulations of the margin width

4. Specification requirements for PE film and Air Bubble Sheet

5. Carton weight specifications and others

6. Are there any special regulations for buffering before placing the board inside the carton?

7. Resistance rate specifications after sealing

8. The weight of each box is limited

At present, the domestic vacuum skin packaging is similar, the main difference is only the effective working area and the degree of automation.

Réamhchúraimí:

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

b. Attach relevant quality certificates, such as slices, weldability reports, test records, and some test reports required by various customers, and place them in the way specified by the customer. Packaging is not a question of the university. Doing it with your heart will save a lot of trouble that shouldn’t happen.
