Technical FAQs:

Q: What is the mating connector for this header?

A: This header is designed to mate with standard 2.54mm (.100") pitch IDC, commonly used in wire-to-board assemblies.

Q: Can I get custom pin counts or modified specifications?

A: We offer a range of standard positions from 2 to 16. For custom configurations, special pin lengths, or alternative plating options, please contact our sales team to discuss your requirements.

Q: What is the recommended soldering process for these headers?

A: These through-hole headers are suitable for traditional wave soldering or hand soldering processes. Standard lead-free solder profiles are recommended, following the temperature guidelines specified in the product datasheet.

Q: What is the pitch and mounting orientation?

A: 2.54mm (.100") centerline pitch, single row, right-angle through-hole mounting for PCB connection.

Procurement FAQs

Q: Do you have this wire-to-board header in stock?

A: Most standard pin count models are kept in regular stock. For large orders or special specifications, please confirm availability 

with our sales team in advance.

Q: What is the minimum order quantity for this series?

A: Standard items come with low MOQ. We welcome both sample orders and bulk purchases.

Q: Can I order mixed pin configurations in one shipment?

A: Yes, mixed orders with different pin positions are acceptable to meet your diverse project demands.

Q: How long is the production lead time for bulk orders?

A: In-stock goods can be shipped within 3-5 working days. Out of stock orders generally take 4-6 weeks based on order volume.

Q: Can you provide customized pin length or surface plating?

A: Custom pin lengths and alternative plating options are available. Please send your detailed requirements for a tailored quotation.

Q: What documents can you provide for export clearance?

A: We can supply commercial invoice, packing list, certificate of origin, RoHS compliance certificate and relevant mechanical test 

reports.

Q: What packaging is used for these connectors?

A: Products are packed with anti-static bags and standard export cartons to prevent damage during transit and storage.

Q: Is the price adjustable for large volume orders?

A: We adopt tiered pricing. More competitive rates will be offered for larger order quantities.

Q: Can you arrange samples for testing first?

A: Yes, free samples are available. Customers only need to bear the courier freight.
