Introdução aos sistemas microelectromecânicos MEMS Os sistemas microelectromecânicos (MEMS) são dispositivos que têm partes móveis feitas de componentes microscópicos. São também designados por micromecatrónica e microssistemas. À nanoescala, fundem-se em sistemas nanoelectromecânicos ou nanotecnologia. Os nanotubos são um processo unitário fundamental para o fabrico de sistemas microelectromecânicos mems Os investigadores [...]
Tips To Know Cold Welding Cold welding is a solid-state process, and it produces a stronger joint than reflow soldering. However, it does require a clean surface. For cold welding to be successful, the metal surface must be completely free of any oxide layers. The surface must also be completely smooth and free of any […]
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 […]
7 Tips for Analyzing the Basic Design Flow of PCB Circuit Board Design As a PCB circuit board designer, it’s important to understand the basic design flow. This will help you decide the components that will make up your PCB. It also allows you to make sure that your PCB components will be compatible with […]
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 […]
What Is Static Electricity? Static electricity is the imbalance of electric charges on a material’s surface. It can occur between two objects or within a material. The imbalance remains until the charge is moved away by electrical discharge or an electric current. For practical purposes, static electricity is used in photocopying, air filters, and many […]
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 […]
Choosing a Reliable PCB Assembly Manufacturer When choosing a PCB assembly manufacturer, it is crucial to consider the level of experience of the company’s personnel. Experienced PCB assembly staff members are more likely to be knowledgeable and dependable. You should also consider the company’s PCB assembly capacity based on your needs and budget. Frequently Asked […]
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 […]
