Soldering Iron Rework Conditions
- Soldering Iron Tip Temperature: 400 (max.)
- Soldering Time: 3.5 sec (max.)
- Soldering Iron Power: 50W (max.)
Storage Environment
- Store products under the following conditions and use within 6 months of delivery.
- Temperature: 10~30, Relative Humidity: 60% max.
- Weld NTC within 168 hours after opening the moisture-proof packaging. After opening, store NTC in the moisture-proof packaging with desiccant and HIC card, maintaining the above conditions.
- If the storage period exceeds 6 months, or the indicator color of the accompanying HIC card changes after opening the package, baking (60 * 168hr) is required before welding.
- Refer to baking data for products that exceed exposure time or environmental requirements before reflow soldering (exposure time restarts after baking).
- Do not store products in corrosive substances like sulfur, chlorine gas, or acids to prevent pin oxidation and reduced solderability.
- Store products on shelves to avoid moisture, dust, etc.
- Avoid thermal shock, vibration, and direct sunlight in the warehouse.
Usage Precautions
- Operating ambient temperature should be within the specified technical range.
- Do not install near heat-generating or flammable components; maintain a gap of greater than 3mm to prevent damage.
- Wear gloves when handling leads.
- This specification guarantees the quality of our product as an individual component. Ensure your product has been effectively evaluated and confirmed according to your specifications when our product is integrated.
- We do not guarantee failures caused by product usage exceeding the defined functions in this test specification.
- In case of NTC damage, failure may lead to a short circuit. To prevent dangerous situations like overheating, smoking, or fire during a short circuit, implement an automatic fail-safe function using components like fuses in the circuit.
