Package
Alternating layers of prepeg and core materials are laminated together under high temperature and pressure to produce Multilayer PCBs. This process ensures that air isn't trapped between layers, conductors are completely encapsulated by resin, and the adhesive that holds the layers together are properly melted and cured. The range of material combinations is extensive from basic epoxy glass to exotic ceramic or materials.
Multi layer PCB is a circuit board that has more than two layers.
Unlike a Double-Sided PCB which only has two conductive layers of material, all multilayer PCBs must have at least three layers of conductive material which are buried in the center of the material.
Applications of Multi layer PCB
While the weight and space benefits of multilayer PCBs are especially valuable for Aerospace PCBs, multilayer PCBs are also beneficial to applications where "cross-talk" levels are critical. These are a few other the applications using multilayer printed circuit boards:
Computers
File servers
Data storage
Signal transmission
Cell phone transmission
Cell phone repeaters
GPS technology
Industrial controls
Satellite systems
Hand held devices
Test equipment
X-ray equipment
Heart monitors
Cat scan technology
Atomic accelerators
Central fire alarm systems
Fiber optic receptors
Nuclear detection systems
Space probe equipment
Weather analysis
