Micro-MaTch Miniature Connector System
Micro-MaTch Miniature Connector System
Miniaturization and the
trend towards higher den-
sity of electronic functions
on a substrate led to the
introduction of smaller
interconnection systems.
The Micro-MaTch connector
family, with it’s contact
spacing of 1.27 mm, fully
complies with the electronic
packaging requirements of
today and the future. The
system offers a range of
board and wire connectors,
enabling a variety of wire-to-
board and board-to-board
interconnections.
The Micro-MaTch contact
concept shown on this page
is essentially different from
other systems available.
By its design the traditional
failure mode in tin plated
connections, fretting corro-
sion, is prevented. Due to
an additional positioning
spring in the female part,
relative movements caused
by vibrations/thermal
expansion between male
and female contacts are
absorbed. By preventing
movements on the contact
spot, a gas tight connection
can be guaranteed under
all circumstances.
The contact spring is
located in the board con-
nector and not in the cable
connector, which is usually
the case. The counter part,
incorporated in the cable
connector, is a simple pin,
either with an insulation dis-
placement section, suitable
for the mass-termination of
cable or with a kinked sol-
der leg to be soldered onto
a PC Board. The separation
of these two basic functions
of the contact system —
contact force generation
and wire termination —
enables the independent
optimization of both func-
tions and also leads to
relatively simple contact
shapes.
Because of their shapes
contacts can be post-
plated, leaving no bare
edges in the contact and
wire slot area. The contact
spring system features an
additional spring member —
the positioning spring —
which compensates posi-
tional tolerances. In this way
the contact spring can be
fully optimized for its basic
function, so that the rela-
tively high contact force,
required for tin plated
contact systems, can be
guaranteed under all
circumstances.
The Micro-MaTch contact
spring system is absolutely
fretting corrosion proof by
its design.
