1. Temperature control
Ambient temperature monitoring: Avoid long-term use of quality bare PCB boards from China in extremely high or low-temperature environments to prevent mechanical stress or cracks caused by thermal expansion and contraction of the resin.

2. Prevent mechanical damage
Avoid excessive bending: PCB boards should avoid excessive bending during installation or removal to prevent cracks or delamination at the resin-filled micropores and blind holes.
Prevent shock and vibration: During transportation and operation, avoid excessive shock or vibration on the PCB board to prevent damage to the resin-filled area.

3. Humidity control
Avoid high-humidity environment: The resin-filled area may be sensitive to humidity, and the resin-filling PCB should avoid long-term exposure to high-humidity environments to prevent performance degradation caused by resin moisture absorption.
Prevent condensation of water vapor: When used in an environment with large humidity changes, water vapor should be prevented from condensing on the PCB surface and the resin-filled area to avoid affecting electrical performance.

4. Cleaning and maintenance
Keep the surface clean: Clean the surface of quality bare PCB boards regularly to avoid dust, oil, or other contaminants that affect welding and electrical performance. It is recommended to use dust-free cloth and appropriate cleaning solvents.
Check the resin status: Regularly check the resin-filled area to ensure that there are no cracks, delamination, or other mechanical damage, especially after high temperature or mechanical stress.

5. Storage and transportation
Proper storage conditions: Keep the PCB board in a dry and low-temperature environment during storage, and avoid high temperature, high humidity, or direct exposure to sunlight.
Safe transportation packaging: When transporting the Best quality bare PCB boards from China, use anti-static packaging materials and provide sufficient buffer protection to prevent physical damage and static electricity accumulation.
