As automotive electronics and electrical connection systems continue to evolve, connector manufacturers face increasing demands for connection reliability, electrical performance, and consistent manufacturing quality.
Press-fit technology has become an important connection solution in automotive applications, offering advantages such as solder-free assembly and efficient production. For Eye-of-the-Needle and other press-fit terminal designs, material selection plays a critical role in achieving reliable connections and stable mass production.
How can manufacturers balance press-fit reliability, electrical conductivity, and stamping performance?
At Shanghai Kinmachi New Material, we offer C19010 copper alloy strip for automotive press-fit terminal applications, with a focus on three key performance aspects.
1. Press-Fit Reliability and Connection Stability
During insertion into plated-through holes (PTHs) on printed circuit boards, Eye-of-the-Needle terminals undergo controlled deformation to establish reliable electrical and mechanical connections. Appropriate material strength and deformation behavior are essential considerations when evaluating insertion force, retention force, and long-term connection stability.
2. Balance Between Mechanical Strength and Electrical Conductivity
Automotive connectors require materials that combine adequate mechanical strength with suitable electrical conductivity. These properties influence terminal performance under actual operating conditions. Proper material selection and application testing can help manufacturers evaluate the balance between mechanical reliability and electrical requirements.
3. Stamping Performance and Batch Consistency
Eye-of-the-Needle terminals often feature precise geometries and demanding forming requirements. Material properties such as elongation, hardness, grain structure, and batch-to-batch consistency can affect stamping stability, dimensional accuracy, and production yield.
Consistent material quality helps support more predictable manufacturing processes and reliable terminal performance.
