Competence in 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 characterised through the matching of the connector
pin and the plated through hole of the pcb. Whereas
the desired electrical characteristics 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.
Due to variety of different connector contact designs,
the press-in zone has been designed to fit perfectly to
the contact metal thickness and the plated through
hole dimensions and tolerances.
Board with press-in connectors
The patented contact
design allows 20 %
more tolerance on the
plated through hole
of 0.6 mm than the
standard tolerance
of 0.6+0.07
-0.05 mm.
D-Sub
The terminating
spoon shape of the
contact provides
a reliable vertical
position of the
connector for better
alignment during
insertion.
SEK
The renowned
needle eye allows
for compensation
of tolerances of
pcb surface
properties. The
excessive material
is displaced within
the plated through
hole whereby a
gastight connection
is assured.

Competence in press-in technology
Due to the high deformation resistance and resilience of
contacts, they can be easily and repeatedly
removed in case of repairs without impairment to their
functioning.
Today tinned surfaces are widely used as a standard,
the pcb technology trends are moving to low tin or tin
free surfaces. Cu, Pd, Au and Ag are the important
alternatives. Specific parameters and particularly
different friction factors of these surfaces make high
demands on press-in zones.
is extremely versatile and offers a reliable
electrical contact, therefore it is especially well suited
for applications with these surfaces.
Please contact us for detailed test reports.
Benefits of the press-in technology
lThermal shocks associated with the soldering
process and the risk of the board malfunction are
avoided.
lNo need for the subsequent cleaning of the
assembled pcb’s

Quality control of the press-in termination
The press-in force correlates with the diameter of the
plated through hole and with the friction coefficient of
the surface; therefore it can be used for a continuous
monitoring of the process.
The retention force, as an indirect measure of the
normal force, serves to qualify the process or random
tests
HARTING assists you with the most advanced quality
assurance methods beyond the usual scope.
The automatic press-in machines of HARTING feature
a graphical user interface for monitoring the process
and the quality of the press-in termination (see chapter
30).

The current carrying capacity is limited by maximum temperature
of materials for inserts and contacts including terminals.
The current capacity-curve is valid for continuous, not interrupted
current-loaded contacts of connectors when simultaneous power
on all contacts is given, without exceeding the maximum tempera-
ture.
