An Introduction to MEMS Micro Electro Mechanical Systems Microelectromechanical systems (MEMS) are devices that have moving parts that are made of microscopic components. They are also called micromechatronics and microsystems. At the nanoscale, they merge into nanoelectromechanical systems or nanotechnology. Nanotubes are a fundamental unit process for manufacturing mems micro electro mechanical systems The researchers at the University of Illinois have made a major breakthrough in microelectromechanical systems, and the discovery has a broad range of applications. Nanotubes are a fundamental unit process in manufacturing mems micro electro mechanical systems, and their work has implications for the design of many new kinds of mems. They have demonstrated that nanotubes can […]

The Comparison Between Blind Via and Buried Via in Manufacturing of Printed Circuit Boards There are several advantages of using buried vias as opposed to blind vias for the fabrication of printed circuit boards. Buried vias can be fabricated at a lower density without affecting the overall board size or layer count. This is advantageous for designers who need to save space while still meeting tight design tolerances. Buried vias also reduce the risk of breakouts. Disadvantages Blind via fabrication involves a series of processes that begin by bonding a photosensitive resin film to a core. The photosensitive resin film is then overlaid with a pattern. This pattern is exposed […]

3 Base Material For Metal Core PCB The basic idea behind a metal core PCB is to eliminate plated through holes, which can cause short circuits. Surface mount components that use THTs are also not allowed on this type of PCB. Instead, copper layers are interconnected via blind vias and buried vias. Multilayer MCPCB If you are developing a product that is going to be exposed to a lot of heat, then a metal core PCB is a great way to keep that heat at bay. However, this type of PCB also requires careful thermal management. To make a MCPCB that is perfectly suited for your application, you need to […]

How to Plan Multilayer PCB Stackup When designing a multilayer PCB, you should take the following factors into consideration. Reference planes for layer 3 signals are usually located on layers 2 and 5. The signals routed on layer 4 use these reference planes. If the reference planes are located on layers far from the signal layers, it’s necessary to use wide traces. This type of tracing is only possible when the common impedance of the layers is equal to 50O or higher. Using a layer stack manager Before creating your multilayer pcb stackup, you should first determine what type of technology you intend to use. This will allow you to […]

A Brief Discussion on Some Important Technical Performances of PCB Ink PCB ink is an important component in the fabrication process. Its performance depends on several characteristics, including its viscosity, plasticity, adhesion, hardness, and water and solvent resistance. It also has properties that help it resist temperature and acid and alkali. Besides, it’s soluble, which helps it act as a bonding material. Viscosity Viscosity of PCB ink is an important factor in screen printing, one of the most important PCB manufacturing processes. The ink must have a high viscosity and good thixotropy to ensure accurate image reproduction. Viscosity is the internal friction that a liquid faces when being agitated or […]
