Multilayer Boards, Double-sided PCBs & more
Our wide selection of multilayer boards production capability is built upon our core concepts of efficiency, repeatability and reliability, supporting the most complex of multilayer PCB requirements in a cost-effective manufacturing environment. Amongst our other PCB capabilities, we offer a range of multilayer options including 2 layer PCBs, 4 layer PCBs and 6 layer boards.
What is a Multilayer PCB?
A Multilayer PCB is a printed circuit board that has more than 2 layers, unlike a double sided PCB or a 2 layer PCB board, which only has two conductive layers of material. All multilayer PCB’s must have at least three layers of conductive material.
A Multilayer PCB is much more complex than a double-sided PCB design and can have any number of layers - choose from 4 layer PCBs to 6 layer PCBs, 8 layers or even up to 64 layers. Multilayer PCB’s are laminated and glued together with layers of heat protection insulation between them.
What is the purpose of a multilayer PCB?
Multilayer boards provide both high capacity and speed in a smaller footprint by their innate electrical properties. Connectors that are required for multiple separate PCBs are reduced or eliminated, simplifying construction and further reducing weight.
Multilayer PCB Board Thickness
Multilayer board thickness is 370 mil and the finished copper weight inner layer 15 oz/ outer layer 15oz. The line width & space of a multilayer PCB is a minimum 3mil/3mi and a minimum drill size cnc 4 mil. The minimum drill size laser drill of our multilayer PCBs is 3 mil, with an aspect ratio of 18:01 and a maximum board size of 43”x26”. The minimum core thickness for Pure's multilayer PCBs is 2mil and the impedance control tolerance +/- 5%.
