PRESS-FIT TECHNOLOGY

Eliminate costly soldering operations and damaging effects of direct press-fit components.

As the industry pioneer, Autosplice offers Press-fit solutions that provide our customers with solderless, internally powerful, gas-tight connections. Press-fit (Compliant) Technology is available in  a large variety of sizes, types and features and is compatible with high speed automation.

 

Press-fit connection relies on normal force, just like a contact system unlike soldered connection which relies on cohesive and adhesive strength of solder joint. Press-fit terminals are assembled onto 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 on-going 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.

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 0.4mm 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.

 

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.

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. 

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

WHY PRESS-FIT?

PRESS-FIT VERSATILITY 

  • Hundreds of tooled components in both soldered and compliant press-fit terminals

  • Allows replacement of terminal in PCB

  • Modularized tooling provides low cost product extensions

  • Scalable insertion systems deliver cost efficient assembly solutions

  • Global design, manufacturing and sales locations

PRESS-FIT VALUE 

  • Fast production process 

  • Compliant press-fit connection is less dependent on manufacturing process for reliability than soldered connection 

  • Provides a simple lead-free solution 

PRESS-FIT RELIABILITY 

  • High normal force along with high retention force ensures reliable connection in automotive environments 

  • Eliminates wave soldering/eliminates screen paste solder 

  • Low contact resistance; reliable interface 

  • Improves product reliability 

     a. No cold solder joints 

     b. Eliminates solder flux contamination

ARTICLES ON PRESS-FIT TECHNOLOGY

The all-new 0.4mm EON press-fit zone is designed to work with the now industry-standard plated-through-hole size of 0.60±0.05mm.

Because the fully compliant press-fit interconnect is finished in a single step, the automated insertion operation can be integrated at virtually any point in the overall production flow.
