Hot dip tinning
Rolled strips can be supplied with hot tin plated coatings in compliance with the DIN EN 13148 standard.
The KME hot tin plated coatings meet the RoHS European Directive (restrictions of the use of certain hazardous substances in the construction of various types of electrical and electronic equipment).
| STOL®Sn10 | Pure tin |
| STOL®Sn11 | thin prec |
| STOL®Sn13 | Thermic tin |
| STOL®Sn28M | Tin-silver |
Hot tin plating is performed on strips that have a width not greater than 330 mm and a thickness between 0.15 and 0.80 mm.
At dimensions greater than these, Electroplating can be performed as illustrated in the diagram below.
| Standard coatings | Advantages |
| 0.6-1.3 μm | Lowest mating and unmating forces |
| 0.8-2.0 μm | Reduced mating and unmating forces |
| 1.0-3.0 μm | Standard coating for connectors |
| 2.0-5.0 μm | Good protection against corrosion |
| 4.0-10.0 μm | Good storage and solderability |
| 10-20 μm | Long life and solderability |
| Other thickness on request | |
FIELDS OF APPLICATION
The hot tin plated coating is one of the more widely requested coatings for our rolled products because it is a fairly cost-effective way of manufacturing complex components, plus it has excellent welding properties.
ADVANTAGES
- Homogeneous adherence between the base material and the layer of tin
- Natural formation of an intermetallic layer
- Protection against corrosion and oxidation
- Less resistance from electrical contact
- Pure tin completely void of lead
- Special coating:
- Tin-Silver
- Layer of thermic tin
TIN COATING PRICE INCREASE
KME has to invoice with immediate effect additional adders
