Press-Fit Technology

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

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.

  • 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.

Almost obsolete technology used in low-cost applications that are insensitive to shocks and vibrations and are not expected to have a long service life.

Mainstream technology with high adaptability for mass applications that require high production throughput. Generally applicable for stamped and molded contact technology with tin plating on the contacts and on the PCB.

The connection is gas-tight, but the coating and the metal cylinder are permanently damaged. The PCB material is attacked in the immediate vicinity of the hole. High risk of metal detachment in the immediate vicinity of the through-hole plating.

Gas-tight connection, but the coating on the contacts and the walls of the through-holes is removed during insertion due to the high frictional forces. This can lead to cracks in the PCB near the holes and the connections can be sensitive to high temperature fluctuations, shocks and vibrations.
