why do you need it?

pin advantages

Low insertion force

Low insertion force simplifies the assembly and makes it cheaper.

Qualification

Pressfit pins 0.50×0.40 mm, 0.60×1.00 mm, 0.60×0.60 mm are qualified in accordance to EN 60352-5. It proved to have required contact resistance (< 0.5 m?), acceptable deformations and resistance to rapid temperature changes and climate sequences.

Compatibility with holes of different diameters

Various pin press shapes allow large tolerances of hole diameter, which makes possible to select insertion and retention forces according to Customer’s demand.

Reparability

Unlike solder joints pins can be designed to be removable to repair connection, if needed.

Cost-efficient

Instead of buying expensive connector, it is necessary to buy only pins that will fit Customer’s component.

Automotive norms

Pin tip dimensions matches norms of such automotive manufacturers as BMW, GM, Daimler-Benz, PSA, VW, etc. Norms consider precut angle, rounding diameter, width and height of a pin tip.

Adaptability

Pin connection is adjustable in height and position, it can be inserted in necessary quantity into various components: PCB, plastic or metal connectors, coil frame, etc.

Easy to go

Thanks to automation it’s possible to insert up to 15000 pins per hour without any experience in pin interconnections.

Deformation and vibrations resistance

Pin insertion doesn’t require additional soldering which means no thermal stress and no damage for components. As a result connection stays reliable under vibrations.

how do we do it?

pin interconnection research

  • 1. PIN PARAMETERS DEFINITION
    We define pin features depending on type of application, connector/component materials, working environment and temperature range.

    What you get?
    Pin material (bronze, brass, CuFe2p, CuMg0.1, CuNi3SiMg, CuNiSi, Staku30), coating material (Ni-based 1.3-3 μ: Ag, Au, Sn), shape (square, round, rectangular), type (smooth, star, winged, harpoon, pressfit, double), length (2-70 mm).

  • 2. TOOLING DEFINITION
    Tooling is defined based on corresponding request by SM Contact engineers with a help of database of former realized connections.

    What you get?
    Equipment type, special tool necessity definition.

  • 3. PIN INSERTION SIMULATION
    With a help of FEA software we build components computer model of defined type and materials and simulate strains and stresses during pin insertion.

    What you get?
    Optimal insertion parameters and its improvement options are specified to match industry norms and Customer’s demand.

  • 4. LABORATORY TESTS
    We make samples and perform laboratory study: press-in and pull-out force, contact resistance test.

    What you get?
    Report with precise connection parameters matching norms and Customer’s requirements.

  • 5. EQUIPMENT MANUFACTURING
    Engineering department adapts automation level, speed, special options and quality control devices.

    What you get?
    Pin insertion equipment customized for Customer’s application, as well as for quality, automation, cost and production volume requirements.

Pin types

This simple-shaped type of pin has chamfers on both ends so that it can be used for connection purposes.

Application

Coil frame, printed circuits without metalized holes, over-molding, plastic components with drilled holes, metal components whose holes diameter has small tolerances.

Dimensions

The Star pin is ideal for printed circuits with metalized holes to compensate holes diameter tolerances after drilling. It offers an excellent mechanical resistance and its shape is often used in “paste-in-pin and reflow” or “pin-in-paste and reflow” processes.

Its star shape, unlike the smooth pin, can be also used advantageously for round holes in plastic elements. When inserted, the smooth tip of a pin enters freely without any damage, while the star part provides its secure retention inside of a component thanks to its 4 peaks.

Application

Single- or double-sided printed circuits, coil frame, plastic connectors.

* Reinforced star

Winged and harpoon pins suit square holes in plastic elements, guaranteeing excellent mechanical resistance of the pins in their seats thanks to its 2 peaks. At the same time the smooth tip of a pin enters freely without any damage.

These pins meet the requirements of automotive manufacturers for connector applications.

Application

Plastic connector.

Pressfit flexible geometry matches components with various hole diameter tolerances. It can deal with deviations of + 0.10 to – 0 mm, in compliance with the IEC 352.5 standard.

Size difference between hole and pressfit zone leads to pressfit deformation during insertion. Subsequent сompression of a pin guarantees reliable connection, which doesn’t need to be soldered.

Application

Double-sided printed circuits. Particularly for automotive industry.
