    Press-Fit Technology

    High-performance and highly reliable
    Connection technology for the aerospace industry

    What is Press-Fit

    With press-fit technology, connectors are pressed onto a printed circuit board (PCB) using appropriately dimensioned through-hole plating without damaging the PCB or the connectors. This technology is an alternative to the soldering process and offers numerous advantages over the conventional process, such as a reduction in production costs or a large selection of different power and signal contacts.

    The low-force press-fit process from our supplier Positronic also prevents distortion of the PCB and damage to the hole due to the low insertion and extraction forces caused by bi-jump power. This expertise in the development and manufacture of press-fit contacts was demonstrated once again in 2018 when our supplier and the CNES (French space agency) were selected to lead a project to qualify SPMAX and DSUB with press-fit contact technology for the European Space Agency ESA.

    THE ADVANTAGES OF Press-Fit Technology

    • Simple, clean, robust and highly reliable connections, even in environments with strong vibrations and temperature changes.
    • High repeatability of the connection impedance
    • Applicable on one or both sides of the PCB
    • Acceptance of large PCB thicknesses
    • Contacts or connectors that are easy to repair or replace
    • Process without heating or cleaning
    • Avoidance of high reflow heat, minimization of thermal stress on the PCB and damage to the connector housing.
    • Available for mass production
    • Reduced control by avoiding e.g. X-rays.
    Press-fit technology helps to improve the reliability of electronic assemblies
    • FIT rate* of 0.005 during press-fitting
    • FIT rate* of 0.5 for manual soldering
    • FIT rate* of 0.03 for the automated process
    *FIT-Rate = Failure-in-Time-Rate
    Failure rate is 100 times lower than with hand soldering
