Process and apparatus for producing metal-laminated base material for printed circuit boards |
摘要 |
A metal-laminated base material for printed circuit boards is produced in a double-belt press. Sheets of laminated material impregnated with an accelerated resin system and prehardened are preheated in a preheating zone, before running into a pressure-effective zone of the double-belt press, and are supplied together with the metal foils to the heating region of the pressure-effective zone. Here, the individual layers are pressed to form the base material. The base material is preferably cooled under pressure in a cooling region of the pressure-effective zone, if appropriate heat-treated, trimmed at the edges and cut to length. The process provides uniform base-material boards of perfect quality.
