As the upstream of the weapons and equipment industry chain, military electronic components are the cornerstone and basic support of military industry informatization and intelligence, and their quality and reliability are directly related to the technical performance, development process, and combat capability of equipment.This article mainly lists the top 10 military electronics manufacturers, especially military electronic components.
Although BJT and MOS transistors are the most popular and common components, they are sometimes limited in some relatively high current applications. That’s where our IGBT comes in handy. So what is IGBT? What is the function of IGBT? What are the working principles, advantages and disadvantages of IGBT? This time let’s take a good look at what IGBT is!
A PCB BOM (Bill Of Materials) provides a comprehensive list of all the components needed for the PCB assembly, including their part numbers, descriptions, quantities, and other relevant information, which serves as the foundationg for PCB Manufacturing or PCBA. A well constructed PCB BOM is vital to result in quality products.
Impedance is the measure of how much current can flow through a circuit at any given time. It can be thought of as the reciprocal of voltage, which is the calculation of how much energy is being transferred from one point to another in the circuit board. PCB impedance control ensures that no excess current flows through the circuits on your PCB during operation; if it does, then this may cause damage or create problems with your production run.
High-speed Printed Circuit Board (PCB) and housing materials are specially designed to manage electrical signals traveling through a circuit board at lightning-fast speeds while simultaneously dissipating the heat generated by devices during operation.
They are essential when designing circuit boards that can withstand the demands of high-speed data transmission. These materials have been specifically designed to meet the needs of modern electrical engineering projects with increased frequencies, higher speeds, and lower profile components. It is essential to carefully consider their characteristics to make the right choice for each application.
Engineers will consider the power integrity and signal integrity of the product during the layout process, but the manufacturability of silkscreen is easily overlooked. For example, the silkscreens cover the SMD pad, which brings inconvenience to the PCB continuity test and component soldering. If the silkscreen design is too small, it will cause difficulty in screen printing, but if it is too large, the silkscreen will overlap each other, making it difficult to distinguish, etc.
Why are circuit boards (PCBs) usually green? Many people are curious about this question. This question also has many different answers. Let’s take a look at why most PCBs are green. There are several accepted reasons.
With the rapid development of electronic products, there are many types of circuit boards, including rigid PCBs, flexible PCBs, and rigid-flex PCBs. Rigid PCBs are ordinary PCB boards that cannot be bent, and most products use PCBs. The flex PCB is a flexible board (FPC), which can be bent to a certain extent, and is generally used in products that are relatively thin or have bending requirements. But do you know any facts about rigid PCB vs flex PCB?
As components also became smaller and the need for more adaptability of a board is smaller spaces, single or double-layered designs were not capable of providing expected effectiveness, giving birth to multilayer design, which considers boards with three or more layers, including, for example, 6, 10, 16 or even 20 layer PCB. In this article, we will explore and dig more on this last option and review some of its characteristics and applications.
A solder joint is a resulting connection between the two surfaces.
It is one of the most important parts in electronics. It connects two or more pieces of electronic equipment and makes sure that they work together well. Soldering joints are used in many different types of products, such as computers, cell phones, and even electric vehicles.
