Socket & Termination Selection

QA Technology offers a wide variety of socket and termination pins to fit your application. The following is a summary of the various options and their applications. Please note, some of these socket or termination styles are only available in specific probe series.

Crimp:

Allows the user to manually attach custom wiring (i.e. different length or colors).

Crimp with Pre-attached Wire:

Used primarily on close center/fine pitch probe sizes where wire wrap is not available. For a reliable connection they are available with a four-jaw, eight (8) indent crimp for the wire attachment. Various wire gauges, lengths and colors are available.

Male Round Tube:

Available with an .039 [1.00] OD with different termination length options. Typically mounted onto edge cards, ribbon cable assemblies or other type connectors. Made to accept a one (1) millimeter receptacle plug. These sockets are made of stainless steel and are recommended for corrosive environments. They are not recommended for solder applications.

No Termination:

Typically used as an inexpensive option. These sockets can be soldered directly to a board or with care can be crimped or soldered into the open end.

Wire Plug:

Allows the user to easily disconnect wire from the socket for trouble-shooting or repair. Bottom of socket is formed to accept wire plugs.

Round Pin:

Used primarily for connectors but can also be directly soldered into board vias.

Solder Cup:

Highly reliable connection used primarily in low-density areas. Can be wave or hand soldered and used in vias or with wire.

Square Wire Wrap Pin:

The most commonly used termination in ATE fixturing. Used for large-scale wiring. Provides excellent electrical integrity by providing a gas-tight connection therefore preventing the effects of corrosion. One of the most cost-effective connection methods for skilled fixture makers because it is fast, reliable and inexpensive.

Wire Jack:

A pluggable wire connection method that allows the user to easily connect a wire, and if necessary, disconnect from the socket or termination pin for trouble-shooting or repair. Wire Jacks are available with or without a pre-attached wire in various gauge sizes, lengths and colors.

Wire Grip:

Allows the user to connect user-supplied 28 or 30 AWG silver plated solid conductor wire directly to the socket or termination pin. Slide a wire grip sleeve over the wire and onto the socket or termination pin to complete the electrical connection and provide insulation and spacing between adjacent contacts.

Double Ended:

Used in wireless fixtures, offering shorter signal path lengths for improved signal integrity from the tester circuits to the unit under test (UUT) than conventional wired designs.
