Manufacturing Multilayer Pcb. As the name suggests a multi layer circuit board can only be called a multi layer circuit board with more than two layers such as four layers six layers eight layers and so on. At technotronix our highly qualified and experienced multilayer pcb manufacturer ensure that all the layers are correctly registered.
To produce a multi layer pcb alternating layers of epoxy infused fiberglass sheet called prepreg and conductive core materials are laminated together under high temperature and pressure using a hydraulic press. General introduction of multilayer pcb. High definition multilayer rigid pcb 1l board golden triangle pcb the product will supply to all over the world such as.
With the invention of new technology multilayer boards can be manufactured with up to 100 conductive layers making sophisticated design where more number of components are joined together.
Laminate is an epoxy resin and glass fibre core with copper foil pre bonded onto each side. Due to the complexity of the multilayer pcb manufacturing process low production volume and difficulty in rework their prices are relatively higher than a single layer and double sided pcb. The whole process needs to be done in an esd safe and cleanroom environment. In fact the multilayer pcb manufacturing process requires an extremely high level of attention to detail especially since the heat and pressure of the manufacturing process should not impact any layer.
