Spring Finger Contacts (SMT)
Spring finger contacts are used for grounding and dynamic connections on electronic assemblies.
These spring finger contacts (SMT) are designed to withstand tens of thousands of compression cycles. They are widely used for connections on automotive projects for example. These spring finger contacts are delivered in reel for automatic SMT assembly.
We provide compression rates and associated forces for each spring finger contact on request. Recommended compression is 20% to 40% of the overall contact height.
Spring finger contacts (SMT) can be standard (see our catalog below) or tailor-made.
Spring finger contacts (SMT), Key points :
- Mechanical resistance of the spring contact >50,000 compression cycles
- Excellent resistance to vibrating environments (automobile, aeronautics, military)
- Automatic assembly (SMT) with reel packaging (7″ or 13″)
- Nickel treatment (weldability) and gold flash (for conductivity and protection)
- Surface resistance of a few milli-ohms.
Large catalog of standard spring finger contacts (SMT) available and possibility to make custom-made parts (dimensions, thickness, materials, overmolding, etc.).
Detailed mechanical report provided on request (dimensions, packaging, compression curves, etc.)
Prototypes and samples of spring finger contacts on request.
Learn more about spring finger contacts (SMT)
These spring finger contacts (SMT or bulk, standard or custom) provide a flexible connection for ground contact for various configurations.
The thermal treatment and the choice of the alloy ensure a high durability (thousands of cycles) with stable mechanic and conductive characteristics.
Especially used as: battery contact, antenna contact and on PCBs.
They can be assembled by pick and place (SMT process) or delivered on bulk for small quantities or prototyping.
Those spring contact are mainly used on Automotive and Industrial fields.
Our design department can analyze the mechanical design requirements before proposing any type of SMT metal contact in your application.
We provide all technical datas for a complete integration of the spring finger contacts on your application.
For example the recommended reflow temperature profile:
Contact our technical teams to obtain 3D and 2D plans for each reference.
We can also provide some spring finger contacts in bulk on request, to support you with your prototyping.
