Multilayer circuit board fabrication is a straightforward process but does require a high level of attention to detail. Sounds simple, but the whole process is time consuming and counting on skilled technicians. Pressure is required to squeeze out air in the laminated materials, and accelerating the combination of copper layers and prepreg under heat, while heat is required to melt and cure the thermosetting prepreg adhesive which holds the multilayer PCB together. Layers of copper foil, prepreg and core material are built up and combined together under high temperature and pressure to produce multilayer printed boards. Manufacturing multilayer PCB boards start by creating the PCB core. Application of this Build-up method then leads to the generation of highly complex PCBs. All electrical connections between the layers are achieved with vias, including but not limit to plating through holes (PTHs), blind and/or buried vias. As a smart multilayer PCB provider, we can work with you to support a large panel of materials. In many cases, these other layers are copper foil, the material in-between cores or copper foils is Prepreg. Multilayer printed circuit board is made with three or more conductive copper layers, set right in the middle with multiple other layers stacking on this core. As a leading supplier of multilayer printed circuit boards, which are more complex and have a variety of differences from the standard single-sided and double-sided PCBs, the ability to manufacture multilayer PCB boards opens up a world of possibilities allowing the electronic engineer to create more densely populated circuit boards which allows miniaturization. Has made the multilayer PCB much more popular are the electronics to be smaller, faster and more functional. The demand for multilayer boards has been on the rise. With the increasing complexity of modern electronics, these multilayer PCBs with significant board size down become more widespread than ever before which contributes to advanced design software, enhanced manufacturing techniques, the art-of-work equipment, new chemicals and materials. More complicated electronic applications, like 4G/5G smart phones, tablets, PCs, GPS, high-end earphones, fire alarms, heart monitor, X-ray and CT scan equipment and industrial controls, and etc. Printed wiring boards (PWBs) for simple electronics with limited functions are usually composed of a single or double layer. While nowadays circuit boards are much more complex in schematic and routing, and multilayer circuit boards are widely used in all kinds of electronics in the world. When the multilayer PCB was invented in 1961, the multilayer boards were relatively simple which limited by manufacturing techniques at that time. Printed circuit boards (PCBs) are the main board of all electronic products, determining functions through combinations of pass and active components and traces routing.
