PCBA Tech - Storage method of PCBA circuit board

Storage method of PCBA circuit board
At present, the country has higher and higher requirements for environmental protection and greater efforts in link governance. This is a challenge but also an opportunity for PCB factories. If PCB factories are determined to solve the problem of environmental pollution, then FPC flexible circuit board products can be at the forefront of the market, and PCB factories can get opportunities for further development.
The Internet era has broken the traditional marketing model, and a large number of resources have been gathered together to the greatest extent through the Internet, which has also accelerated the development speed of FPC flexible circuit boards, and then as the development speed accelerates, environmental problems will continue to appear in PCB factories. In front of him. However, with the development of the Internet, environmental protection and environmental informatization have also been developed by leaps and bounds. Environmental information data centers and green electronic procurement are gradually being applied to the actual production and operation fields. From this point of view, the environmental protection problems of PCB factories can be solved from the following two points.

PCBA circuit boards are the provider of electrical connections for electronic components and play an important role. After the PCBA circuit boards are completed, they need to be stored to avoid damage to the PCB circuit boards. So what is the storage method of PCBA circuit boards? The following technicians will introduce:

1. The PCBA circuit board needs to be vacuum packed in a colorless air-ball plastic bag, and the vacuum packaging bag should be accompanied by a desiccant and ensure that the packaging is tight. It should not be in contact with air and water to prevent the surface of the PCB circuit board from being oxidized by immersing gold, spraying tin and bonding pads, which will affect the welding, which is not conducive to production.

2. When packing PCBA circuit boards, it is necessary to surround a layer of bubble film on the side of the box. The bubble film has better water absorption, so that it can absorb water and prevent moisture. In addition, moisture-proof beads are also indispensable.

3. Place the PCBA circuit boards according to the classification and label them. After sealing, the box must be stored in a dry and ventilated place with partition walls and off the ground, and avoid sunlight.

4. The warehouse temperature for PCBA circuit board storage is best controlled at 23±3 degree Celsius, 55±10%RH. Under such conditions, PCBA circuit boards with surface treatment such as gold, electro-gold, spray tin, and silver plating can generally be stored 6 months, PCBA boards with surface treatment such as immersion silver, tin, OSP, etc. can generally be stored for 3 months.

5. For PCBA circuit boards that are not used for a long time, it is best to apply a layer of three-proof paint on them. The three-proof paint can prevent moisture, dust and oxidation. In this way, the storage life of PCBA circuit boards will increase to 9 months.

About the storage method of PCBA circuit boards, today's hundreds of achievements are introduced here. In fact, the storage time of PCB circuit boards is related to the surface treatment. Chemical gold and electroplated gold are the longest storage time. Under constant temperature and humidity conditions, they can be stored for two to three years. Doing a good job of PCBA circuit board storage can better extend the service life of the circuit board, which is a problem that cannot be ignored.
