PRESS-FIT TECHNOLOGY
COMPLIANT PRESS-FIT PINS AND CONNECTOR COMPONENTS
Autosplice manufactures compliant press-fit pins, blades, sockets, and connector components for reliable solderless PCB connections. Our eye-of-the-needle designs create gas-tight, low-resistance connections while reducing stress on plated-through holes.
Products are available in continuous-reel formats for high-speed automated insertion, with standard and custom options for automotive and other demanding applications.
As an industry pioneer, Autosplice offers press-fit solutions that create solderless, gas-tight connections in a wide range of sizes, configurations, and features. These components are compatible with high-speed automation, with each part number engineered to support traceability and efficient global shipping.
Press-fit connection relies on normal force, just like a contact system, unlike a soldered connection, which relies on cohesive and adhesive strength of the solder joint. Press-fit terminals are assembled onto the PCB via high-speed insertion machines.
The “eye-of-the-needle” approach has been proven to provide the most reliable technology for optimizing both initial and ongoing retention force. The spring-like design used in eye-of-the-needle configurations provides intimate, long-term contact force against the barrel of the hole with precise compatibility for a plated-through-hole (PTH) hole diameter of 0.60±0.05mm.
All of Autosplice’s compliant pins, blades, and sockets are provided in continuously reeled formats as either individual or multiple-position connector components for insertion by high-speed automatic machines.
INTRODUCING
0.4 mm PRESS-FIT TERMINAL
The all-new 0.4 mm EON press-fit zone is designed to work with the now industry-standard plated-through-hole size of 0.60±0.05mm. The press-fit zone achieves optimum retention strength at each end of the PTH size range by employing a combination of elastic and plastic deformation, which is biased towards the former at the lower end of the PTH size range, and towards the latter at the higher end of the PTH size range. At no point is the elongation allowed to exceed the material limit, to eliminate the likelihood of micro-crack formation or thermal stress that could compromise long-term connection integrity.
Autosplice has elected to standardize the press-fit material to the high-performance CuNiSi (C19010), but will offer CuSn4 and CuSn6 if required. Additionally, the terminal will be offered in standard and reduced tin plating. The latter is especially relevant in high-density terminal applications to reduce the likelihood of tin whiskering.
NEW PTH SIZE OF 0.60±0.05 mm
The all-new 0.4 mm EON press-fit zone is designed to work with the now industry-standard plated-through-hole size of 0.60±0.05mm, a critical hole diameter specification that enhances compatibility and insertion reliability
STANDARD MATERIAL
Autosplice has elected to standardize the press-fit material to the high-performance CuNiSi (C19010), but will offer CuSn4 and CuSn6 if required.
EXCEEDS REQUIREMENTS
The 0.4 mm design was then refined by laboratory testing to achieve the current design, which exceeds all published automotive Tier 1 requirements and has proven resilient against thermal stress in harsh environments.
TOOLING & ASSEMBLY
Assembly of the 0.4 mm press-fit terminals to PCBs can be efficiently accomplished with an Autosplice insertion machine and a custom-designed insertion head — an ideal setup for integrating compliant pin connectors into automated production lines.
