BS EN 13148:2010EN 13148:2010 (E) 5 Introduction Hot-dip tinned strip is manufactured by passing strip through a molten bath of tin, tin-lead alloy or other tin alloys. By this process a solid bond is created between

26、 the metallic coating and the strip by formation of a layer of an intermetallic phase and a diffusion zone. The base metal is hot-dip tinned to protect it against corrosion, to facilitate soldering operations, to improve insertion and withdrawal forces of connectors, to reduce contact resistance at

27、electrical junctions and to avoid whisker growth on components. The properties of coatings can be modified by mechanical and/or thermal treatments. When the strip is emerging from the bath the thickness of the coating is adjusted by partially wiping off the molten film, either by stationary wiping d

28、evices or by a flat air jet. The thickness of the coating can be continously measured and regulated on both sides of the strip during or after the tinning process. Usually strips are tinned in larger widths and slit to narrower width specified by the customer. In this case, the final slit product ha

39、r by symbol or number (see Tables 1 and 2). 4.1.2 Symbol The material symbol designation is based on the designation system given in ISO 1190-1. NOTE Although material symbol designations used in this European Standard might be the same as those in other standards using the designation system given

40、in ISO 1190-1, the detailed composition requirements are not necessarily the same. 4.1.3 Number The material number designation is in accordance with the system given in EN 1412. 4.2 Material for the coating The coating is designated by the coating type (see Table 3) or for non-standardized coatings

41、, by the suppliers designation. NOTE Due to solution and/or diffusion processes the composition of the coating can differ from that of the melt. BS EN 13148:2010EN 13148:2010 (E) 8 4.3 Material condition of the hot-dip tinned strip For the purposes of this European Standard, the following designatio

42、ns, which are in accordance with the system given in EN 1173, apply to the hot-dip tinned strip but are actually the material condition designations of the strip before tinning. R. Material condition designated by the minimum value of tensile strength requirement for the product with mandatory tensi

43、le strength and elongation requirements; H. Material condition designated by the minimum value of hardness requirement for the product with mandatory hardness requirements; G. Material condition designated by the mid-range value of grain size requirement for the product with mandatory grain size and

44、 hardness requirements. Exact conversion between material conditions designated R., H. and G. is not possible. Material condition is designated by only one of the above designations. 4.4 Product The product designation provides a standardized pattern of designation from which a rapid and unequivocal

45、 description of a product is communicated. It provides mutual comprehension at the international level with regard to products which meet the requirements of the relevant European Standard. The product designation is no substitute for the full content of the standard. The product designation for pro
