Points For Attention
- The best warranty period for product installation is within 180 days from the date of manufacture.
- After taking out and using the product, the remaining unused products must be sealed with sealing tape to prevent oxidation of the pads from affecting welding.
- Any water stains, sweat stains, or dust in contact with the pads will affect solderability. Do not touch the product pads directly with bare hands to avoid affecting welding.
- This product will change due to changes in working conditions. When you need to use this product in other applications, please re-test.
- Excessive voltage, current, or temperature can cause irreversible damage to the product, potentially leading to functional degradation or failure.
- This product is not suitable for humid, dark, and strongly corrosive environments.
