Import Board To Board Connector — Buy in wholesale FOB from Supplier in China

This board to board connector is a surface mount type with a 0.5mm pitch, designed for dense PCB layouts. It features a female contact configuration with phosphor bronze terminals plated in gold, and an insulator made from high-temperature plastic rated UL94V-0. The contact resistance is specified at a maximum of 20mΩ initially and 50mΩ after environmental exposure, with an insulation resistance of at least 50MΩ and a dielectric withstand voltage of 200V per minute. The operating temperature range is -30°C to 80°C, suitable for consumer and industrial environments.

The connector uses copper alloy contacts with phosphor bronze as the base material, selected for its spring properties and wear resistance. Gold plating ensures low contact resistance and corrosion protection in humid or mildly corrosive settings. The insulator material complies with UL94V-0 flammability standards, a common requirement in automotive and appliance applications. These specifications align with industry norms for fine-pitch SMT connectors, though exact tolerances for insertion force and mating cycles are not disclosed and should be confirmed with the supplier.

These connectors are used in household appliances, industrial control panels, automotive wiring harnesses, and communication modules where compact PCB-to-PCB connections are needed. Buyers include OEMs sourcing for volume production and repair suppliers needing replacement parts. Packaging options include PE bags, tape and reel, trays, PVC tubes, and custom formats. The supplier accepts sample orders and offers OEM/ODM services for custom pin lengths and housing designs, with lead times ranging from 5 to 30 days depending on order volume.
