The multilayer presses of the MLP-L series are devices for the production of multilayer PCBs (multilayers) for prototype and small series production.
The system can be used to press together multi-layer circuits made from different PCB materials. Uniform hydraulic pressure distribution combined with a vacuum frame system and freely programmable preheating and process temperatures ensure optimum material bonding across the entire working surface.
With separately controlled, electrically heated press plates and a hydraulic system, the MLP-L model series offers high functionality for a wide range of manufacturing processes.
The MLP-L system is loaded with pressing tools from the front. It is operated via a graphic touchscreen panel. All process sequences are carried out automatically and managed.
The touchscreen panel displays the operating status, programme stages and remaining times in real time. Pressure control is infinitely variable via a hydraulic system using a proportional valve and pressure transducer. The system can be cooled by air or, optionally, by water.
Loading side with tilting elements in the heating plate, enabling contact-free removal of the pressing tool during the loading process.
