PCB-Assembly

  Have you ever opened up an electronic device and wondered what the green board inside was? That, my friend, is called a PCB or Printed Circuit Board. It’s the backbone of nearly all electronic devices today. But, not all PCBs are created equal; some are big, complex, and incredibly fascinating. This article will take you on a journey through the world of big PCB boards, breaking down their complexities into something digestible for everyone. So, whether you’re a curious mind, a budding engineer, or just someone who appreciates the marvels of modern technology, let’s dive in together! What Are Big PCB Boards? Imagine you’re building a skyscraper. In the same way that a skyscraper needs a strong foundation to support its structure, electronic devices need a solid base for their components. That’s where big PCB boards come in. Unlike their smaller counterparts, big PCB boards are designed to support more complex and numerous electronic components, allowing for more sophisticated fun...

  Have you ever wondered about the brains behind your electronic devices? What makes them tick, buzz, and light up? The answer often lies in a hidden hero: the Printed Circuit Board (PCB). Specifically, we’re diving into the world of   thick PCB boards . Now, don’t let the technical term scare you off! Think of a PCB as the nervous system of your electronic devices, where the “thick” part just refers to its robustness, akin to having a strong backbone. This article is your easy-to-follow guide through this fascinating terrain, crafted especially for the general public like you and me. Let’s unravel the mystery together, shall we? What is a Thick PCB Board? Imagine a sandwich. Yes, you heard right—a sandwich. A thick PCB board is much like the hearty, multilayered kind you might pack for a big adventure. It’s a type of PCB that, due to its increased thickness, offers enhanced durability and support for heavy or high-power components. This thickness typically exceeds the standar...

  In order to achieve more reasonable design and better anti-interference ability for high frequency PCB(Microwave RF PCB), design engineer should consider the tips as following: Use inner layer as power ground layer, which will have the effect of shielding and even decreasing spurious inductance, shorten length of signal wire, reducing Cross interference between signals. Circuit layout must be turn with 45 degree angle, which will help to reduce high frequency signal emission and coupling between each other. The shorter the better for length of circuit layout. The less the better for through holes. Layout between layers should be in vertical direction, top layer as horizontal direction and bottom layer as vertical direction, because this will help to reduce the signal interference. Increasing copper on ground layer to reduce the signal interference. Do package for important signal traces can obviously improve signals anti-interference ability. Of course we can also do package for ...

  With more and more electronic product design functions, the products are getting smaller and smaller, so more and more product designs have begun to use   double-sided  flexible boards   (Double sides FPCB) or even   multi-layer flexible boards   (Multi-Layer FPCB). Recently, products with a combination of hard and soft boards have appeared. The most common way to make this kind of double-sided flexible board is to use a substrate with double-sided copper skin, and then make a double-sided through hole (Plating Through Hole).) production, the biggest difference is the thickness and material of the substrate, in addition, the PCB does not need to press the surface cover layer (cover film). The production of through holes is usually first drilled on the substrate with copper skin, and then metallized with chemical copper or other conduction techniques, and then the hole wall is thickened to the required thickness by electroplating. The copper is thick, and ...
