Definitions

  • the invention relates to a partially hot-dip tinned strip made of coatable material according to the preamble of claim 1.
  • Partly tinned tapes on one or both sides can be produced, for example, by the process according to US Pat. No. 4,529,628.
  • liquid metal is partially applied to a belt on one or both sides via a nozzle.
  • the thickness of the coating is controlled by the belt speed and the nozzle output.
  • the layer thickness is therefore identical across the entire range.
  • the coating is continuous over the length of the belt. It is only possible to apply one coating material per strip side. If several coating materials or different properties are required on one strip side, several production steps in succession are necessary.
  • this method does not offer the possibility of coating the strip edges, which is required with regard to solderability in the edge area or when making contact via the strip edge. This process is therefore not highly economical.
  • the invention is therefore based on the object, in particular to expand the range of partially tinned strips in accordance with the needs of the electronics industry.
  • the object is achieved in that the strip - seen in the longitudinal direction - is interrupted at regular and / or irregular intervals (A 1 , A 2 , A 3 ). Distances (A 1 , A 2 , A 3 %) in the range from 1 to 20 mm are preferred.
  • the strips have different layer thicknesses (D1 / D2), or the strips consist of different coating materials.
  • the advantages of thin Sn layers with, for example, low insertion and drawing forces can be shared the advantages of thick Sn layers combined with good solderability (especially for connectors).
  • Harder coating materials e.g. in the contact zone with softer coating materials e.g. can be combined in the crimp or solder area.
  • Copper, copper alloy, iron or iron alloy are preferred as the strip material; Pure tin, tin alloys or zinc are preferably available as coating materials.
  • the invention further relates to methods and apparatus for producing the partially hot-dip tinned strip.
  • the method assumes that the moving strip is provided with flux and heated and that molten metal is applied to the heated strip from at least one storage chamber via at least one opening and excess molten metal is stripped off.
  • the method is characterized in that the supply of the molten metal from the opening is selectively opened and closed.
  • different coating materials can also be used in one and the same strip.
  • the storage chamber feeds at least two openings lying next to one another.
  • the invention achieves structures in which the coating strips are notable for high adhesion.
  • Partially tinned tapes are used in electronics and electrical engineering. They are used, for example, to manufacture connectors for the automotive industry, telecommunications and others. Some coated tapes are also used in the manufacture of semiconductor components such as QFPs (Quad Flat Package), SOTs (Small Outline Transistor), ICs (Integrated Circuit) and others here the combination of the bare strip surface with a well solderable tinned surface.
  • QFPs Quad Flat Package
  • SOTs Small Outline Transistor
  • ICs Integrated Circuit
  • the tape 1 according to Fig. 1 and 2 is each provided with four coating strips 2, 3, 4, 5. According to Figure 1, these are arranged approximately in the middle of the tape, according to Figure 2 on the tape edges. In both Fig.1 / 2, the strips 2, 3 on the top of the tape should have a layer thickness D1, the strips 4, 5 on the underside of the tape should have a layer thickness D2. Furthermore, it is indicated in FIG. 2 that the strips 2, 4 consist of a different coating material than the strips 3, 5. Only the two FIGS. 1/2 show the multiple possibilities of tinning the strip with different distances (A 1 , A 2 , A 3 ...) interrupted strips 2, 3, 4, 5.
  • the strip 1 running off a decoiler 6 passes through a flux feed 7 and for heating comes into a heating chamber 8, in which an insert 9 is integrated, in which a storage chamber 10 is arranged.
  • the metal melt 11 located in the storage chamber 10 is thus kept at the same time at the temperature.
  • the insert 9 rests resiliently on the belt 1.
  • the metal melt 11 provided for coating can reach the strip 1 via an opening 12.
  • Means for controlling the melt supply are indicated by paragraph 13.
  • the layer thickness of the strip 2, 3, 4, 5 to be applied can be varied by the subsequent stripping 14 for the molten metal 11 and / or by the insert 9 being pressed more or less strongly onto the strip 1.
  • the tinned strip 1 is finally rolled up on a reel 15.
  • a storage chamber 10 feeds two openings 12 lying next to one another.
  • the insert 9 has two storage chambers 10 opened laterally to the legs 8 'of the heating chamber 8, so that strips 2, 3, 4, 5 result on the edge strips.
  • these storage chambers 10 are connected to grooves 16 in the heating chamber 8 which encompass the strip edges (means for controlling the supply of melt are not shown in more detail here).
  • the heating chamber 8 which is essentially U-shaped in cross section, can consist, for example, of a base plate provided with heating cartridges, onto which a graphite plate and side legs 8 'are also screwed from graphite.
  • Graphite can also be provided as the material for the insert 9.
  • Tapes with the following dimensions can be tinned: thickness: 0.05 to 1.5 mm, width: 5 to 200 mm.
  • Tinning temperature 50 to 400 ° C.
  • Layer thicknesses of 0.2 to 25 ⁇ m can be achieved.
  • the strips partially coated in this way have an intermetallic phase between the coating and the base material, which increases the adhesion of the coating, so that the coating does not flake off during bending processes even after heat treatments.
