What is a Multilayer PCB?
A Multilayer PCBs consist of multiple layers of electronic components placed over each other. Through-hole construction was the technology that was used to deal with planting the electrical components through the holes on the Printed Board Curcuit and then soldering them together. When this technology was found wanting in complex cases, Point-to-Point construction technology evolved. This proved to be better than its predecessor, but in no way is it comparable to a multilayer PCB. The development of multilayer PCB has allowed electronic companies to drastically cut down on the cost and size of their products. The functionality of a multilayer Printed Board Circuit depends on the internal connections between the various components that make up the entire device. Until and unless these components work in tandem, the device is non-functional. In the case of most technology, the urge to improve product performance makes the products bulky, whereas the flexible design of the multilayer PCBs
