Connection Options for F822 / F832

The Kelvin probe can be mounted either in a simple mounting receptacle or in the Feinmetall combination receptacle with SSMB connection. With the simple mounting receptacle, the connection is made at the receptacle and at the sense pin. Alternatively, the sense pin can also be connected with a connection element.

Using the combi receptacle and the corresponding SSMB connector, no further soldering of connection cables is required.

Advantages of the combi receptacle:

• Solderless replacement of the Kelvin probe
• Easy mounting
• Simple connection of the cables
• Connector offers a defined measuring path with fixed parameters

Position Sensor System

The position sensor system is a modular designed contact probe with a small integrated potentiometer. In addition to realizing an electrical contact to the DUT it allows an exact measurement of the travel of the plunger. This can be useful whenever exact, quantitative and documentable measuring results are required, e.g. for testing connectors or housings in the automotive industry, for the evaluation of injection molded parts or for testing the bending of PCBs.

L’article High Current Probes – Feinmetall est apparu en premier sur Cotelec.

Typically the surfaces of all elements of contact probes are galvanically plated in order to protect the basic material against corrosion. At the assembled contact probe the plating also reduces friction and thereby leads to low abrasion and low contact resistances. FEINMETALL plating materials are basically galvanic nickel, chemical nickel, gold, hard gold, longtime gold, rhodium, silver or progressive coating. To achieve the maximum performance the ideal selection and combination of coating materials, coating thicknesses, coating alloys as well as various boundary processes have to be made.

Switch Probes

Special probes with integrated switch element are mainly used for presence tests. Switch probes close or open an electric circuit after a defined travel of the plunger (switch travel). For nonconductive contacting, switch probes are available with various insulated tips.

Connection of Receptacles

Almost all receptacles are available with solder or crimp connection. Wire wrap connections are frequently used for test fixture manufacturing because they can be wired automatically. Some receptacles (especially those with very small diameters) are available with pre-assembled wires. Additionally, to connect coaxial probes, special connecting elements can be used.

Variable adjustment of the switch travel for push-back probes

The usage of push-back probes in combination with threaded probes on a second level allows a variable adjustment of the switch point (closing of the electric circuit) by height adjustability of the second level. To guarantee a reduced depth of the module we recommend the usage of the short-travel probe F722 together with the push-back probes VF4, VF3 or VF100

A typical application is the measurement of low impedance resistors, especially in narrow spaces.

Pointing Accuracy and Radial Tolerance

The pointing accuracy of a spring contact probe is determined by many factors, for example by manufacturing tolerances, by the length of the plungers and by the type of plunger guiding. Further factors that are independent of the contact probe have to be considered, for example the receptacles and the mounting of the test fixture or module. To optimize the pointing accuracy especially in applications with small centers additional guiding plates in the fixture can be used.

• Guided insertion with LED indication of the correct cavity
• Electrical continuity test of the wire harness in the same operation step

Previous solutions are either based on pure fibre indication in the cavity, without allowing electrical tests, or on LED indication next to the cavity, which is much less effective in terms of guiding the operator, leading to a higher risk of wrong assemblies.

Advantages of the LED contact probe solution

Both functions (LED indication and contacting) are included in one contact element. This leads to correct connector assembly and allows electrical test in one process step.

Barrel : FEINMETALL barrels are usually made of nickel silver, bronze or brass. Nickel silver barrels are deep-drawn whereas barrels made of bronze are turned or deepdrawn and barrels of brass are turned. All barrels are usually silver or gold plated. A small hole in the bottom permits the barrels to be thoroughly cleaned during manufacturing and ensures continuous wetting in the plating process.

Life Cycle Test of Contact Probes

The life cycle of spring contact probes is depending on the design of the probes as well as on the operating conditions in the field. High lateral forces, high current load and contamination may lead to a significantly reduced lifetime of the probes.

For us as manufacturer of these probes, it is vital to permanently control and review the quality parameters and to analyse the lifetime performance of our products. In our own laboratory we have various test and measurement setups for quality control and for the determination of technical parameters during research and development. One important subject is the life cycle test, conducted with seven autonomous stress stages. The test conditions provide an internal standard reference that allows competent statements regarding the life cycles of our probes.

Special Head Made of Silver Alloy

In high current applications ideally no voltage should apply and accordingly no current should flow during closing or releasing the contact. Otherwise, an electric spark may occur, which may damage the surface of the contact area. To avoid or at least minimize such a contact burn-off, FEINMETALL offers tips made of a special silver alloy to minimize the contact burn-off, reducing the transition resistance and lead to a longer life time of the probes.

While ICT (in-circuit test) contact probes are used to test components, FCT (functional test) contact probes can be used to test entire assemblies.

FCT Contact Probes
During functional testing (FCT), the assemblies are tested completely or in partial areas for the intended operation. The function test of the modules is carried out in the end application or in an environment that simulates the end application.
