In today's digital age, technology has become an integral part of our daily lives. One of the most breakthroughs in technology is printed circuit board (PCB) designing. PCBs are the foundation of almost all electronic devices, from smartphones to laptops – you name it. A high-performance and reliable PCB should be well-designed and manufactured, or else it could lead to catastrophic consequences. To achieve a high-quality PCB, the 4-layer PCB is at the forefront.But what is a 4-layer PCB? Simply put, it has four layers of copper traces separated by an insulating layer, also known as a dielectric layer. Unlike its 2-layered counterpart, a 4-layer PCB offers a myriad of benefits. It enables a higher density of components, provides better and more stable signal integrity, allows for easier implementation of ground planes, and has a lower electromagnetic interference (EMI) and crosstalk. As a result, 4-layer PCBs are widely used in complex electronic systems, especially in high-speed communication applications.So, what is the process to make a 4-layer PCB? The first step is to start with the layout design. The designer uses PCB design software to create a schematic diagram, which is then translated into a physical design layout. Once this is done, the designer must choose a suitable substrate material – commonly FR-4 – and determine the thickness of the copper foil required.Next, the designer creates a drill template for each layer, which determines the location of the holes that will be drilled throughout the board. The board is then laminated together with adhesive, and the copper foil is etched away to create the layer's traces. An automated machine drills holes through the board at the specified locations, and the inner layers are aligned to the drill holes and laminated onto the previously assembled layers.Once the layers are assembled, the board is plated using electroplating, and a solder mask is added to provide insulation and protection to the copper traces. Lastly, the board is silk screened with the component placement legend, a code that displays each component's location and orientation.As the demand for technological devices continues to rise, the development of high-quality and reliable PCBs like the 4-layer PCB is crucial. In this regard, several manufacturers are investing in the development of advanced PCBs.
