Abstract
A method for producing electrical connector strips which have soldering extensions arranged within an insulating carrier where the strip is formed apart from the insulating carrier and treated with an active deoxidation agent, tinned in the region of the soldering extensions, then placed in the insulating carrier and finally free-cut in such a fashion as to preserve solderability of the extensions.
Claims4
A method for producing an electrical connector strip comprising the steps of:
- providing a thin planar strip of metal from the group consisting of brass or tin-bronze,
- partially cutting the strip to form critical edges thereby,
- treating the thereby formed thin planar strip with a strong deoxidation agent,
- tinning only those selected portions containing said critical edges of the connector strip to which solder connections are to be made,
- affixing an insulation carrier to the strip,
- and free-cutting the strip at non-critical edges to form a plurality of connector elements to preserve the solderability of the tinner portions.
