The Benefits of Prototyping PCBs

Jump To: The Benefits of Prototyping PCBs | What Is a PCB Prototype? | Benefits of Prototyping | 1. Reduced Timeline | 2. Manufacturing Review and Assistance |  3. Accurate, Reliable Prototype | 4. Test Components Individually  | 5. Reduced Costs | When to Use Prototypes | Get Quality Prototyping From Millennium Circuits Limited The Benefits of Prototyping PCBs Before beginning a full production run, it’s essential to ensure that a printed circuit board (PCB) is functioning properly. Regardless of how carefully designers work on the project, small mistakes and invisible problems always pose a threat to the functionality of the final product. If these problems aren’t caught before full production, it can be extremely costly for the project as a whole. As a result, many engineers regularly order prototype boards before full-scale manufacturing. Prototyping is one of the essential services we offer at Millennium Circuits Limited, but not everyone is familiar with prototype services and their benefits

Types of Vias

Jump To: What Is a Via? | Main Types of Vias | How to Determine the Right Via Requirements for Your PCB Types of Vias   In electronics and computing devices, the circuitry is conducted by a tiny green board that transfers various signals from the control prompts and to the screen. In every smartphone, for example, a printed circuit board (PCB) can be found inside with various chips and components that conduct the signals for thousands of different features and commands. Each time you push one of the prompts on the touchscreen, you are activating one of the signals on the internal board. Most of these signals are conducted through PCB vias. What Is a Via? In a printed circuit board, vias are holes that pass through the layers of the board for the purpose of conductivity. Each hole functions as a conductive path through which electrical signals are

Copper Filling of Blind Microvias

Jump To: Copper Filling of Blind Microvias | What Are Microvias? | What Are Blind and Buried Vias? | Advantages of Copper-Filled Blind Microvias | What Are Copper-Filled Vias? | Challenges Associated | Thermal and Electrical Conductivity | The Copper Filling Process | Copper-Filled Copper Filling of Blind Microvias Vias, the holes through which stacked pads are electrically connected, are essential parts of printed circuit boards (PCBs). As electronic devices, namely smartphones and other similar products, become more popular and shrink in size, the ability to place smaller vias on the board becomes increasingly useful. You also need to be able to reliably transfer signals through the layers of the PCB — which can be accomplished by adding a copper layer to the board substrate — but filling the vias with copper provides extra capacity. Copper-filled blind microvias enable high-density interconnect (HDI) boards and also provide reliable signal transfer. While there are challenges associated with this type of via, they also come with many advantages. Keep reading

What Is a PCB Legend?

What Is a PCB Legend? A PCB legend is a layer of text placed on a printed circuit board (PCB) to label components and provide other useful information. Sometimes called silkscreen or component identification, legend text is printed on top of the circuit board’s solder mask as one of the last steps in the circuit board manufacturing process. Though a PCB may not technically require a legend to function, this text provides information that’s vital for assembly, testing and troubleshooting by the end user. Some common pieces of information included in a PCB legend include: Reference indicators labeling component types Polarity indicators labeling the polarity of certain components Component outlines indicating where components should go Test points to assist with testing and troubleshooting Manufacturer information, serial numbers and other labeling By indicating proper orientation and placement of components and providing other information about the circuit board, a legend helps ensure

Rigid PCB vs. Flexible PCB

Rigid PCB vs. Flexible PCB Both rigid and flexible printed circuit boards (PCBs) serve to connect electronic components in various consumer and non-consumer devices. As the names suggest, a rigid PCB is a circuit board built on a rigid base layer that cannot bend, while a flexible PCB, also called a flex circuit, is built on a flexible base capable of bending, twisting and folding. Though traditional and flexible PCBs both fulfill the same basic purpose, it’s important to note that they have many differences. Flexible circuits are more than just PCBs that bend — they’re manufactured differently from rigid PCBs and offer various performance benefits and drawbacks. Learn more about the properties of rigid PCBs versus flexible PCBs below. How Are Rigid PCBs and Flex Circuits Different? A rigid PCB, usually known simply as a PCB, is what most people think of when they imagine a circuit board. These

PCB Lead-Free Regulations

PCB Lead-Free Regulations Until recently, lead was almost ubiquitous in the construction of printed circuit boards (PCBs). Due to its melting point and ability to form strong bonds between surfaces, a eutectic lead-tin alloy proved highly effective as a solder material. However, as electronic waste volumes increased, the use of lead in circuit boards came under scrutiny in Europe and elsewhere. Lead is a toxic material known to cause serious health and developmental problems in humans and animals. Though electronics containing lead may not pose major threats while in the hands of consumers, lead can leak into the environment after devices are discarded in landfills. To prevent excess amounts of lead from entering the ground, water and air, several governments have placed restrictions on the use of lead in printed circuit boards. What Regulations Control the Use of Lead in PCBs? Two main regulations control the use of lead in

What You Need to Know About PCB Assembly

Jump To: PCBA Terminology | Through-Hole Assembly |  Surface Mount Technology | Mixed Technology | PCB Manufacturing at Millennium Circuits Limited What You Need to Know About PCB Assembly The printed circuit board (PCB) assembly process consists of various steps that must be performed in the proper sequence for the finished product to function as designed. To ensure that this happens, PCB manufacturers use screen templates and controlled heating and cooling mechanisms to regulate how components are applied and fastened into place. When you assemble a printed circuit board, you must choose the right technology for the type of components at hand. All of the parts and pieces must be correctly aligned in their designated spot, as specified in the PCB design. Any deviation, ever so slight, can have huge ramifications on the functions of the finished board. PCBA Terminology To understand the PCB assembly process, you need to know the meaning of several terms: Substrate: The foundational material
