The invention relates to a method of producing a masking tape (11),
which is intended for being used with a strip in which the metal
structures are supported by a plastic film (3) bonded to the metal
structures, said film being provided with required recesses for exposing
parts of the applied metal foil to an electrolyte. After the metal foil
has been applied on the plastic film said metal foil has been shaped to
the form of the required metal structures by means of a chemical etching
process. The masking tape is formed of a material which corresponds with
the material of which the plastic film is made and having a thickness at
least substantially equal to the thickness of the plastic film,
recesses (13) are provided in the masking tape, whereby the same means
are used as for providing the recesses in the plastic film.
