PCB Tech - PCB aging test standards and packaging shipments

The comprehensive effect of temperature change and electrical power is used to conduct aging test on PCBA. The purpose is to simulate the daily use environment of the product, thereby exposing PCBA defects, such as poor soldering, component parameter mismatch, and faults during debugging, etc. The defective PCBA board is eliminated and improved to stabilize the parameters.

PCB aging test standards

1. Low temperature work

After placing the PCBA board at a temperature of -10±3°C for 1h, under this condition, the rated load should be carried. Under the conditions of 187V and 253V, all procedures should be powered on and the procedures should be correct.

2. High temperature work

After the PCBA board is placed at 80±3 degree Celsius/h, under this condition, with load, under the conditions of 187V and 253V, power on and run all the programs. The program should be correct.

3. High temperature and humidity work

Put the PCBA board at a temperature of 65±3°C and a humidity of 90-95% for 48 hours, and run the programs with the rated load. Each program should be correct.

This is the PCBA aging test standard, I hope this article can provide you with some reference!

How PCBA is packaged and shipped

How is PCBA packaged and shipped? In fact, the packaging and shipment of PCBA is also very particular, because the bumpy journey may cause unnecessary wear and tear on the circuit board. In order to avoid these unnecessary wear and tear, technicians will also package and ship PCBA in accordance with certain transportation and packaging requirements.

PCBA packaging and shipment

PCBA packaging method

1. Use anti-static EPE foam pallets for packaging, turnover and transportation.

2. Use permanent anti-static black injection-molded pallets for packaging, turnover and transportation.

3. Use anti-static blister tray for packaging, turnover and transportation.

4. Use 3G turnover vehicles for packaging, turnover and transportation.

5. Use other special designated turnover devices for turnover.

How PCBA is packaged and shipped

1. Confirm PCBA with customers on site

2. PCB anti-static cotton bag packaging

3. PCB full box packaging, according to different quantities to choose different specifications of turnover boxes

How PCBA is packaged and shipped

PCBA transport packaging requirements

1. Packaging materials

PCBA board is a relatively fragile and easily damaged product. Before transportation, it must be carefully packaged in bubble bags, pearl cotton, electrostatic bags, and vacuum bags.

2. Anti-static packaging

Static electricity will penetrate the chips in the PCBA board. Since static electricity is invisible, intangible, and easy to generate, it is necessary to use anti-static packaging during packaging and transportation.

3. Moisture-proof packaging

Before packaging, the PCBA should be cleaned and dried on the surface, and sprayed with three-proof paint.

4. Anti-vibration packaging

Put the packaged PCBA board into an anti-static packaging box. When it is placed vertically, it should be stacked up to no more than two layers. A spacer should be placed in the middle to keep it stable and prevent shaking.
