Double-sided and single-sided PCBs have two and single layers respectively. They are useful for different applications. Multilayer PCBs have three or more layers of conductive material that are buried underneath the core of the material. |
You must be wondering about how PCB manufacturing companies in India produce these circuits? They are made by laminating several layers under high pressure and temperature.
It is ensured that no air gets trapped in between the layers and the conducting surfaces are encapsulated by resin and adhesives. These adhesive materials hold the different layers together.
Melting and curing make the manufacturing process complete and the variety of material ranges from Teflon to ceramic and glass to synthetic base.
Typical structure of 4-layer PCB
The material of prepeg and core are the same, but prepeg is not fully cured so that it becomes malleable as compared to the core. Lamination process fixes the alternate layers.
The manufacturing process involves high pressures and temperatures so that prepeg melts up and joins the different layers.
A gradual cooling process results in a perfectly melted solid and hard multilayer board. PCB manufacturing companies in India use a precise process to ensure zero error in the production.
What are the typical benefits and applications of multilayered PCB?
As compared to single and double-layered PCBs, there are several applications of multilayered PCBs?
• They have higher assembly density as compared to other types of PCBs.
• The size in small, hence, there is a considerable saving on space.
• Multilayered PCBs are flexible and offer easy impedance features.
• It reduces the overall weight as the need for interconnection wiring harnesses gets reduced.
As far as applications are concerned, these PCBs are especially useful where cross-talk levels are desired low.
Due to space and weight benefits, PCB manufacturing companies in India supply large quantities of PCBs to the manufacturers of data storage, file servers, Mobile transmission, computers and GPS systems.
They are also used in manufacturing industrial controls and satellite systems. Modern handheld devices, X-ray equipment, CAT SCAN technology and other medical equipment, use multilayered PCBs.
They are also used in atomic accelerators, high-end fiber optics receptors, space age technology and sophisticated weather analysis systems.
The wide use of multilayered PCBs opens a huge market for manufacturers. Several manufacturers are there in the competitive market, offering a wide range of PCBs for consumers. Open market and fair competition offers equal opportunities to everyone,
