A: Proper packaging of PCB circuit boards is crucial to prevent damage during transportation. Here are some suggestions:
Antistatic packaging: PCB circuit boards are highly sensitive to static electricity and must be packaged using antistatic materials such as antistatic foam or bags. This helps prevent electrostatic discharge from damaging the PCB circuit boards.
Foam padding layer: Add foam padding layers to the bottom and sides of the packaging box to provide additional cushioning and protection. This effectively reduces the impact of external shocks on the PCB board.
Suitable packaging box: Choose packaging boxes with sufficient strength and rigidity to prevent crushing or twisting during transportation. Ensure that the box size matches the PCB board size to minimize movement inside the box.
Labels and instructions: Clearly label the fragility of the packaging and provide correct handling instructions. This helps loading and unloading personnel to handle these packages with extra care.
Filling material: Use appropriate filling materials such as foam particles or airbags inside the packaging box to ensure that the PCB board remains fixed in place, reducing vibration and collision during transportation.
