English copy

A strong DC connector supplier is more than a product catalog. The right partner can translate an application into a controlled drawing, a repeatable process, documented inspection, and dependable delivery.

Ask whether the supplier has experience with your application, current level, assembly process, environment, and target market. Verify who owns the mold, which processes are in-house, and how materials, plating, molding, soldering, and final assembly are controlled.

Request a first-article report, critical-dimension inspection, electrical test data, environmental tests, traceability, nonconformance procedure, certifications, lead times, and change-control records. Compare suppliers using the same drawing and test requirements.

FAQ

Question	Answer
What is the most important supplier question?	Ask how your application will be tested, controlled, and supported after approval.
Should tooling be made in-house?	In-house tooling can improve response speed and change control, but capability and ownership still need verification.
How many suppliers should be compared?	Compare at least two or three qualified suppliers using the same requirements.
