Understanding EMC and EMI in PCB Design

Electromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI) are critical factors in PCB design that can significantly impact device performance. EMC refers to an electronic system’s ability to function properly within its electromagnetic environment without generating disturbances that affect other nearby devices. On the other hand, EMI is the unwanted electromagnetic energy that can cause interference, leading to malfunctions or degraded performance in electronic circuits.

What is HDI PCB Stackup?

HDI PCB stackup is a multilayer printed circuit board (PCB) that uses high-density interconnects (HDIs) to connect its various layers. HDI technology allows for smaller and more densely packed circuitry than traditional PCBs, making them ideal for use in space-constrained electronic devices.

What Are Surface Mounted Devices and Why Do They Matter?

Sometimes, it feels like technology is developing faster than I can hope to keep up with. Still, I do my best to keep myself in the know, despite the challenges that can come with that. If you’re like me or are already a total tech junkie, hopefully, this article will provide useful insights! Surface-mount technology, or SMT for short, has made a big impression in the last few years. It’s becoming a popular form of fitting components. Devices made in this fashion are called surface-mounted devices, or SMDs. If you aren’t sure what any of that means, continue reading for some explanations!

PCB Material: The complete Guide in 2022

Printed circuit boards have become helpful in many ways. You will find them in almost every electronic gadget. Moreover, the demand for PCBs has increased. Many pieces of equipment and device manufacturers need printed circuit boards for the manufacturing process. However, many people are confused about the materials used in PCB manufacturing. This is because the performance and durability of a PCB board depend on the material used. So, to ensure you select the suitable materials for the board, you need to review the available materials. Below is a complete guide on the PCB materials you can consider in 2022.

What is Heavy Copper PCB? Major Applications and benefits

Heavy copper PCB, also known as thick copper PCB, is a printed circuit board with 3 ounces (oz) of copper or more on the internal and external layers. Moreover, a heavy copper PCB is a circuit board having a copper thickness of greater than 4 ounces per square foot (ft2). What is the thickness of copper on a PCB? The 1 oz completed copper weight selection is also the usual beginning copper weight for external layers on PCBs. Standard internal layer copper thickness for “standard construction product for 1 oz and 2 oz finished copper weight options is 1 oz copper (35m thick or 1.4 mils).

PCBs are the neatest and professional-looking among the assembled circuit types. But soldering is still required on the copper patterns on the board. In the early 1900s, before printed circuit boards existed, the only way circuits were made for electrical or electronic components was by wiring them point to point on a chassis. These chassis were either a pan or a sheet of a metal frame with a wooden bottom. The components attached to this chassis were connected with either wire connector lugs or crimp connectors or via jumper wires by soldering their ends or some other method. These primitive methods made circuits very fragile and large or bulky, and their production was very labor-intensive, so the products were expensive. Albert Hanson, a German inventor, thought flat foil conductors joined with a board insulated in multiple layers in 1903. The very next year, in 1904, Thomas Edison was experimenting with chemical methods to plate conductors on paper. But it wasn’t before 1913 that the printing and etching method was patented; Arthur Berry in the UK coined this method. These printed circuits did not come into common consumer electronics until the 1950s.

What are Common types of advanced PCB materials?

Modern electronics demand more and more advanced PCBs. They need to be denser, more reliable, and more complex. Traditional PCBs cannot always provide the expected characteristics, so PCB manufacturers are investing in advanced PCB manufacturing equipment to make advanced PCBs at a rapid pace and low cost. Common types of advanced PCBs Generally speaking, an advanced PCB is a board that is manufactured differently than a conventional FR4 PCB. The different technological processes and materials define the advancement. Common types of advances PCBs are: The list may not be complete as technology evolves, and there may be new technologies and materials be involved. Each of the PCB technologies has its own purpose and place. Why you should use a different PCB than FR4 conventional PCB?

PCBWay comes with new excellent service – rapid prototyping

When you think what new can a PCB fab house offer – PCBway pulls something new and exciting out of the sleeve. Recently they have introduced a rapid prototyping manufacturing. This is way beyond PCB fabrication because prototyping covers CNC machining, sheet metal fabrication, 3D printing and even injection moulding. So not you can get PCB and take care of mechanical parts such as enclosures and dynamic components. CNC machining CNC machining allows milling complex parts out of raw material using programmed tools. CNC service includes milling, lathe, laser machine, water jet machine, electric discharge machine – all that may be needed to cut complex 3-dimensional parts. While other CNC technologies are used to cut raw material, the main work is performed by CNCN milling and CNC turning. CNC milling uses a router bit and 3-axis system to move it around the workpiece. More complex parts may be prepared by using up to 6-axis system. CNC turning is used when the part needs to be symmetrical around a single axis. The workpiece is rotated, and two axis-controlled blade removes material from workpiece until the piece is finished. Sometimes multiple milling technologies are incorporated to produce complex parts. CNC machining is…
