Tinning of electrical contacts
Tin plating of electrical contacts etc. to improve chemical resistance and solderability for electrical engineering, telecommunications, appliance manufacturing and the automotive industry.
Overview of services:
- Tin plating of small to very small connectors in barrel plating process
- Tin plating of contact parts and contact points
- Tinning of sleeves
- Tin plating of ends on current and grounding strips
- Partial tinning of contact points
- Good solderability of the tin layer
- Manual electroplating of individual parts for small quantities
- Very soft - can therefore be used as filling layer
- Special sizes on request
The silver-white, very soft metal has many advantageous properties in a tin coating. It has good chemical resistance and good solderability. In the functional area, tin plating is widely used for electrical and electronic components.
