26、04 (E) 5 0 Introduction 0.1 General This document covers the requirements relating to metallic strips coated with tin or an alloy of tin, using a con- tinuously applied electrolytic process. This type of process consists in subjecting the strips to different surface treatment operations in an instal

27、lation through which they travel, starting from an unwinding system and generally finishing on a winding system. Certain surface treatment operations may be chemical or thermal (degreasing, pickling, finishing, etc.), but the tin or tin alloy coating is achieved by cathodic electrolysis. Strips coat

28、ed using this method are generally intended to be cut and fashioned into individual pieces attached to a system of supporting or pre-assembled strips. Tin or tin alloy coatings are mainly intended to protect the base metal against corrosion, to facilitate soldering operations, to improve insertion a

29、nd withdrawal forces of connectors and to reduce contact resistance at elec- trical connections. The tin or tin alloy is most often applied directly to the strip. However, in certain usage conditions (temperature higher than 120 C, for example) the diffusion phenomena can be harmful (for example alt

30、eration of sol- derability). In such cases it is recommended that an appropriate sub-layer be interposed between the base metal and the final coating layer. This sub-layer is itself obtained by electrolysis. The thickness of the coating and/or the sub-layer depends on the intensity of the electrolys

31、is, as well as the conveying speed in the treatment installation and the lengths of baths. Controlling these parameters enables the thickness of the coating and/or the sub-layer to be regulated with a precision in the order of several tenths of a micrometre. This thickness can be measured and regula

32、ted con- tinuously during the production cycle. Appropriate technology can be used, if necessary, to obtain different thicknesses of the coating and/or the sub-layer on each side of the strip and/or partial application of a coating and/or sub-layer. Usually strips are tinned in larger widths and aft

33、erwards slit to narrower width specified by the customer. In this case, the final slit product has untinned edges. 0.2 Types of electrolytic tinning process and types of coatings of tin or tin alloy 0.2.1 Process for matt electrolytic coatings Matt appearance coatings are obtained using baths which

34、do not contain brightening agents. However, all matt coatings baths (except stannate-based baths) contain grain-refining agents or other additives which pro- duce a matt appearance. These products are generally based on organic compounds. 0.2.2 Process for bright electrolytic coatings Bright (reflec

35、tive) appearance coatings are obtained using baths containing one or more appropriate brighten- ing agents (brighteners). These products are generally based on organic compounds. A proportion of this (these) brightener(s) is incorporated into the coating as it is formed. Its presence may prove undes

36、irable with respect to subsequent melting or soldering operations (gas or blister formation on the coating, formation of a heterogeneous structure). It can, on the other hand, be beneficial with respect to fric- tion properties (low-friction contacts). EN 14436:2004 (E) 6 0.2.3 Process reflow bright

37、ened electrolytic coatings Reflow brightened coatings are obtained by heating a matt electrolytic coating above its fusion (melting) point for a few seconds, and then cooling it before contact with any element of the installation (guide element, transport element, etc.). The coatings remain bright a

38、fter cooling. During this operation, the temperature of the strip reaches levels very close to that of the fused coating. Different techniques exist for heating the strip as it is in motion after the coating operation: through-type gas furnace, infra-red, induction heating, oil bath, ohmic effect, s

39、team, etc. In practice, on-strip reflow brightening is not used for coatings of thickness greater than 5 m (risk of running), nor for coatings which are already bright. NOTE Electrolytic tin coatings may be subject to spontaneous growth of metallic whiskers (combined effect of humid- ity and mechani

40、cal stress, for example). This phenomenon is highly undesirable for electrotechnical applications (risk of short-circuit). The risk of it occurring can be reduced by reflow brightening, using tin-lead alloy coatings or inserting an appropriate underlayer. 1 Scope This document specifies: the composi

41、tion and tolerances on dimensions in the thickness range from 0,1 mm up to and including 4 mm of strip of copper and copper alloys to be tinned with tin or a tin-lead alloy or other tin alloys; the composition of the material to be used for the coating; the properties of strip before tinning; the pr

42、operties of the electrolytically tinned strip; the preferred thicknesses (mean values) and thickness ranges of coatings and their eventual sub-layers; the types of coating and sub-layer; the edgewise curvature of electrolytically tinned strip; the sampling procedure; the methods of test to be used f

43、or verification of conformity to the requirements of this standard; the delivery conditions. 2 Normative references The following referenced documents are indispensable for the application of this document.
