BARE MATERIAL

The strips must be clean and free of detrimental defects, which must be specified by agreement between the customer and the supplier when requesting the quote and in the order. Normally, a small residual layer of lubricant is left on cold-rolled products, which is authorised unless otherwise specified.

ROUGHNESS EN 1654

This must be agreed between the customer and the supplier when requesting the quote and confirming the order.

SURFACE CONDITION EN 13599

The strips must be clean and free of detrimental defects, which must be specified by agreement between the customer and the supplier in the request for quotes and in the order. Normally, a small residual layer of lubricant is left on cold-drawn products, and this is acceptable unless otherwise specified. Discolouration is acceptable, provided that it is not detrimental to the use of the product.

TIN COATINGS

Tin coatings for strips and copper strips and copper alloys:

ELECTROLYTIC tinning EN 14436

ELECTROLYTIC TIN PROCESS TYPES AND TYPES OF TIN COATINGS AND TIN ALLOYS EN 14436

Process	Description
Process for matt electrolytic coatings.	This is the standard finish of a traditional electrolytic bath.
Process for bright electrolytic coatings.	Coatings with a bright appearance are obtained using baths that contain one or more suitable brightening agents (brighteners). Their presence may not be desirable in subsequent melting or soft soldering processes. Furthermore, they may be beneficial for frictional properties (low friction or sliding contacts).
Process for flow-brightened electrolytic coatings.	Flow-brightened electrolytic coatings are obtained by heating a matt electrolytic coating above its melting point for a few seconds and then cooling it. The coatings preserve their sheen after cooling. In practice, flow brightening is not used for coatings with thicknesses above 5 μm (slip risk) or for coatings that are already bright.

NOTE - Tin electrolytic coatings may experience a spontaneous growth of metallic filaments (the combined effect of humidity and mechanical stresses, for example). This phenomenon is highly undesirable for electrotechnical applications (risk of short circuit). The risk of this happening can be reduced by flow brightening, using tin-lead alloy coatings or inserting a suitable sublayer.

3.5	2	5	Preventing corrosion
5	3	7	Extending the useful life
7.5	5	10	To aid soft soldering
10	7	13	To aid soft soldering

The appearance depends on the type of liquid film cooling, the type of coating and the technique used to remove excess molten metal. The surface may have a bright or matt appearance, or a combination of both. The appearance of the coating does not affect its suitability. If there are special requirements for the appearance of the coating, these requirements must be agreed at the time of the quote and/or order.

EN 14436. The thickness of the strip prior to tinning must be in accordance with the approximate tolerances given in the table above. The thickness tolerance of the tinned strip must take into account the minimum and maximum thicknesses of the coating.
