Introduction to Multilayer PCB A Multilayer PCB, also known as a multilayer printed circuit board, is a complex and advanced type of PCB that consists of multiple layers of conductive copper foil laminated together with insulating material. These layers are interconnected through plated holes called vias, which allow electrical signals to pass between the different…

What is a Resistive Touch Sensor? A resistive touch sensor is a type of touch-sensitive interface that detects touch input by measuring the change in electrical resistance between two conductive layers when they are pressed together. It consists of a sandwich of layers, including a flexible top layer and a rigid bottom layer, separated by…

What is Free Energy? Free energy, also known as “over-unity” energy, refers to the concept of creating a system that generates more energy than it consumes. In other words, it is the idea of producing energy without any external input or fuel source. This concept challenges the fundamental laws of thermodynamics, which state that energy…

What are Blind Vias? Blind vias are a type of interconnect used in printed circuit boards (PCBs) that start on an outer layer and terminate on an inner layer, without going through the entire thickness of the board. Unlike Through-Hole Vias, which penetrate all layers of the PCB, blind vias are “buried” within the board,…

Introduction to Innerlayer imaging Innerlayer imaging is a crucial process in the manufacturing of multilayer printed circuit boards (PCBs). It involves transferring the circuit pattern onto the copper-clad laminate, which will be used as an inner layer in the final PCB Stack-Up. The accuracy and precision of innerlayer imaging directly impact the functionality, reliability, and…
