Definitions

  • the present invention relates to a contact spill for use in the manufacture of a backplane in a telecommunications environment, for example.
  • Hitherto 0.l inch backplanes have used existing DIN 4l6l2 spills, in the production of such backplanes, and employ preformed solder rings which are inserted over the pin and rest on the backplane and then heated until the ring melts thereby making an electrical connection.
  • an aim of the present invention is to provide a spill which enables good electrical contact to be made with the plated-through hole during manufacture of the backplanes, which is less expensive than previously used spills and solder preforms.
  • a contact spill for use in the manufacture of a backplane provided with a plated-through hole for the reception of the spill, wherein the portion of the spill arranged to co-operate with the plated-through hole is formed in a manner which allows the spill to experience an interference-fit with the hole, and is further prepared with a coating to permit the spill to be subjected to reflow solder process and thereby make a good electrical contact with the plated-through hole.
  • a portion of the spill is formed into an H cross-section and the central limb of the H cross-section is provided with a slot arranged to inwardly collapse as the pin is fitted into the plated-through hole.
  • the flanges of the H cross-section are inwardly bent to allow the pin to be accomodated in the hole easily.
  • the flanges of the cross-section are outwardly bent to allow the pin to be accomodated in the hole easily.
  • Sections G and H of the spill B are gold plated to a thickness of 2.5 micrometres, and section I is coated with tin lead in readiness for use in solder reflow process.
  • Figure 2 shows a backplane J having several plated-­through holes and a connector moulding K having holes in alignment with the plated-through holes.
  • a spill B is shown in position in one of the holes.
  • the flanges D,E suffer compressive forces and the longitudinal hole F begins to collapse inwardly. The result is that the spill B is easily forced into the plated-through hole, and experiences an interference-fit therewith.
  • the backplane is then subjected to a solder reflow process causing the coating of tin-lead on the spill and the plated-through hole coating to melt and mix thereby giving a good solder joint at least in the areas L, Figure 3, Figure 4.
  • Figure 4 shows an alternative form of cross-section to that shown in Figure 3.
  • the flanges D and E are bent outwardly. As the spill B is inserted into a plated-through hole, the flanges D,E suffer compressive forces and the longitudinal hole F begins to collapse inwardly. The result is that the spill B is easily forced into the plated-through hole, and experiences an interference-fit therewith.
