Abstract
PURPOSE:To save man-hours for build-up and to improve workability, by placing notches made in the materials along projections in a jig frame in a laminating and pressing process for manufacturing a multi-layer printed circuit base plate. CONSTITUTION:A jig frame l having projections l is placed on a jig plate m and a multi-layer printed circuit base plate is therein constituted. One face or both face printed base plates j and j and prepregs k and k are placed in a specific constitution and a jig plate i is thereon placed. Moreover, when lamination is done, a hot plate (a) and a cushion material (b) are used to hold the laminated plates between them. A method for positioning the printed base materials j and the prepreg k to be laminated (both are plural) is to place successively the printed base plates j and the prepreg k having notches whose positions and dimensions are fitted with the projections in advance in a jig frame l having the projections h. Lamination is easy to carry out as the projections should be merely fitted with the notches like this, and treatment of prepreg resin which flows out after pressing also becomes easy.
