Press-in technology
Solderless termination for connectors has proven to be reliable for
decades. Today the use of press-in connectors encompasses all
fields of electrical and electronical applications.
Pressing of electrical components, mainly connectors, is characte-
rised through the matching of the connector pin and the plated
through hole of the pcb. Whereas the desired electrical characteri-
stics can be attained relatively independant from the design of the
press-in zone, the mechanical characteristics of the press-in zone
are crucial for the reliable assembly of connectors where pcb's
have different surfaces.
Although the scope of requirements at the press-in process is
generally defined in time-tested specifications, the novel press-in
zones should offer an optimal handling and a reliable termination.
Essentially, this is guaranteed through the design of the press-in
zone and the meticulous observance of tolerances. HARTING has
been using FEM simulations for the calculation and optimisation of
press-in zones for a long period of time. This expertise allows us to
simulate various pcb configurations very accurate.
Benefits of the press-in technology
● Thermal shocks associated with the soldering process and the
risk of the board malfunction are avoided.
● No need for the subsequent cleaning of the assembled pcb’s
● Additional wrap connections are made possible by using
connectors with long pins
● Unlimited and efficient processing of partially gold-plated pins
for rear I/O - manual soldering is no longer necessary!
