Micro-MaTch Miniature Connector System 

Miniaturization and the trend towards higher density of electronic

functions on a substrate led to the introduction of smaller interconnec-

tion systems. The AMP 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 AMP Micro-MaTch contact concept

shown on this page is essentially different from other systems available.

By its design the traditional failure mode in tinplated connections,

fretting corrosion, 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 connector 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 displacement

section, suitable for the mass-termination of cable or with a kinked

solder 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

functions 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 positional tolerances. In this way the contact spring can be

fully optimized for its basic function, so that the relatively high contact

force, required for tin plated contact systems, can be guaranteed

under all circumstances.
