Abstract

The proper flow of resin in the lamination of a multilayer printed circuit board is critical for a number of subsequent operations. Because resin flow is dependent on a variety of conditions that can cause problems, the monitoring of the platen displacement and its alignment, that are used in the lamination process, provides a method of identifying flow variations for corrective action. Lamination is a squeezing flow geometry. A schematic of the geometry is given in Fig. 1.
