As electronic devices become more compact yet increasingly powerful, the need for advanced circuit board technology has grown. The multilayer circuit board has emerged as a crucial solution for meeting these modern demands. Unlike single-layer or double-layer PCBs, multilayer boards consist of three or more conductive copper layers stacked with insulating materials between them. This structure allows for higher density, improved performance, and greater functionality, making multilayer boards indispensable in industries such as telecommunications, computing, aerospace, automotive, and medical electronics. What is a Multilayer Circuit Board? A multilayer circuit board is a printed circuit board designed with multiple layers of…
