Title:
METHOD OF PERFORATING COVERLAY FILM
Document Type and Number:
WIPO Patent Application WO/2008/010289
Kind Code:
A1
Abstract:
A method of perforating a coverlay film, characterized by including the first
perforating step of making multiple first product holes (H1) and two
reference holes (H4) in coverlay film (W) by means of first perforating
metal die (510) and the second perforating step of making multiple second through-holes
(H3) in the coverlay film (W) by means of second perforating metal die
(540), wherein in the second perforating step, the two reference holes (H4)
are photographed to thereby measure the positions of the reference holes (H4)
in the coverlay film (W), subsequently the position and/or posture of the coverlay
film (W) against the second perforating metal die (540) is regulated on the basis
of measuring results, and thereafter second product holes (H3) are
formed in the coverlay film (W). Accordingly, this coverlay film perforating
method realizes forming of the product holes (H3) made in the second
perforating step to the product holes (H1) made in the first perforating
step with precision corresponding to miniaturization and as a result, forming
of a product hole pattern finer than in the prior art.
