    摘要: The present invention provides a process for producing printed circuit boards which comprises the steps of

    (a) roughening a surface of a copper layer (2) formed on an insulating board (1),
    (b) coating the roughened surface of copper layer (2) with a photo-resist layer containing a sublimable copper-cor­rosion inhibitor, exposing the resist layer selectively to actinic rays according to a circuit pattern to form, and de­veloping the resulting resist layer, thereby forming plating-­resist coats (4) on circuit-negative pattern portions of the copper layer (2),
    (c) heat-treating the plating-resist coats (4),
    (d) plating chemically the circuit-corresponding portions with copper (5),
    (e) removing the plating-resist coats (4), and
    (f) removing the copper layer (2) except the circuit-cor­responding portions thereof.

    A photosensitive resin composition having preferable resolution and heat resistance was found. A multilayer circuit board, of which thermal stress generated in the steps of a reflow process, a gold wire bonding process, and a repairing process in a bare chip mounting process, and peeling off the conductor wiring and deformation of the multilayer circuit board caused by mechanical stresses at the heating processes were suppressed, was obtained.
    Accordingly, decreasing size and weight of electronic apparatus became possible.
