Frequently Asked Questions
Q
What is bridge riveting, and why does it matter for coin cell battery connectors?
Bridge riveting is a mechanical joining technique that locks the spring contact securely in place, preventing detachment during use. For coin cell battery connectors, this means the spring will not loosen or pop out under vibration or repeated insertion cycles, ensuring a stable and consistent electrical connection throughout the product's lifespan.
Q
What is the daily production capacity for these custom-shaped coin cell battery connectors?
Thanks to our proprietary intelligent equipment cluster of over 40 dedicated machines and a fully automated bridge riveting process, we achieve a stable daily output of more than 2 million sets. This capacity supports large-scale OEM and ODM orders while maintaining consistent quality throughout every production batch.
Q
What corrosion resistance options are available, and how are they tested?
We offer selectable corrosion resistance grades validated through neutral salt spray testing at 24, 48, or 72 hours. The standard model (023F) comes with a 48-hour salt spray rating. Customers can request higher grades depending on the application environment, such as humid or industrial settings. All surface treatments are RoHS and REACH compliant.
Q
How is solderability quality assured across different production batches?
Every production batch undergoes consistent solderability testing to verify wetting performance and long-term bonding integrity. This batch-level quality control ensures that each shipment meets the same high solderability standard, reducing the risk of solder joint failures during your assembly process and improving overall production yield.
Q
What material and surface treatment are used for the 023F model?
The 023F model is manufactured from SUS301 stainless steel, which provides excellent spring-back properties and mechanical strength. The surface is finished with nickel plating, offering enhanced corrosion resistance, consistent contact resistance, and reliable solderability — all critical requirements for modern automated battery assembly lines.
Q
Are these connectors suitable for fully automated assembly equipment?
Yes. These connectors are specifically designed and manufactured with high verticality and superior metal flatness, making them highly compatible with automated pick-and-place and soldering equipment. The precision dimensions (9.44 × 9.68 mm) and consistent spring force ensure seamless integration into automated production lines, minimizing jamming, misfeeds, or alignment issues.
