PCB Thickness

Jump To: What Is Standard Thickness for PCBs? | Design Factors That Impact PCB Thickness | Manufacturing Factors That Impact PCB Thickness | 3 Factors to Consider When Choosing PCB Thickness | Request a Free Quote PCB Thickness When referring to dimensions for manufacturing applications, standards are essential to understand and work with. This is especially true for circuit boards. While there is no official standard for PCB thickness, certain sizes are preferred and commonly used among manufacturing companies. These preferred thicknesses are highly recommended to simplify design, effectively leverage manufacturing equipment and minimize costs. However, PCB thickness can vary, and many designers may choose to alter PCB thickness for specific design and manufacturing purposes. Here, we look into what “standard” PCB thickness means and how to determine the PCB thickness for your next project.  What Is Standard Thickness for PCBs? MCL’s standard base thickness is 0.062 inches, or 1/16 inch, with a 10% tolerance. This is a very

Single-layer PCBs themselves are becoming increasingly complicated, but PCB layouts are needing to provide even more features within compact spaces. As a result, many manufacturers are turning toward multilayer PCB stackups. So what is a PCB stackup? How does it work, and do you need it for your applications? Here are some essential points about PCB stackups to help you make an informed decision. The Purpose of PCB Layer Stackups A PCB stackup refers to the arrangement of copper and insulating layers that make up a PCB. These

PCB Temperature

PCB Temperature Temperature is an important element of safety, reliability and performance in printed circuit boards (PCBs). High temperatures can quickly lead to malfunctions and permanent damage. Several circumstances can introduce heat into the workings of a PCB. A component mounted to the PCB might produce excessive heat. An external element — for example, another component in a complex system like an aerospace system or medical application — might generate excessive heat. Heat might build up in the PCB because of inadequate ventilation. Or during PCB assembly, the heat produced during drilling and soldering might cause undue thermal stress on the components and lead to defective boards. Whatever the reason, engineers need ways to manage heat to ensure that PCBs can survive the high thermal stresses they will inevitably encounter. What are some effective PCB heat dissipation techniques and ways to prevent PCB temperature rise? We’ll answer these questions in

What Causes Damages to Flexible PCBs

What Can Damage Flexible Printed Circuit Boards? Flexible printed circuit board (PCB) damage can relate to one of two types of factors — environmental and manufacturing. By partnering with a dependable supplier, you can protect your flexible PCB from these risks. Environmental Factors That Can Cause Flexible PCB Damage The following environmental factors can damage flexible circuit boards: Moisture: When moisture crosses two channels on a PCB, it can result in circuit board failure. A moist or humid environment can cause a PCB to come into contact with water. In addition, moisture can encourage the growth of mold, another factor for PCB damage. Static electricity: Fabric and carpet surfaces can create small static electricity charges that can cause severe PCB damage. In fact, a static charge can blow an entire etch off of a circuit board. Dust: Dust in a PCB can lead to damage due to its behavior as an insulator. In operating

What Is the Use of Test Points in a PCB Circuit?

What Is the Use of Test Points in a PCB Circuit? As a design for test (DFT) approach, test points streamline the PCB testing process. These design elements will enable you to verify your PCB’s function during development. By creating a PCB with test points, you can improve processes that happen in later stages of production. What Are Test Points on a PCB? A PCB test point is a small wire loop used for test probes on a PCB that contains surface-mount parts. During production, they enable the user to inject test signals or monitor the board’s circuitry. Test points come in a variety of materials, sizes and colors. With a test point, you can create an access area for your test probe. Many of these probes have J-hooks designed for older PCB styles that included leads. A PCB test point provides a place for the J-hook or has a

When Should I Use Bare Board Testing?

When Should I Use Bare Board Testing? A bare board and the bare board testing process have critical roles to play in printed circuit board (PCB) creation. In PCB development, the bare board layout determines your placement of through holes and electronic components. This PCB substrate also defines a finished board’s connections through its printed circuits. By using bare board testing in your PCB development process, you can improve the reliability of your results. What Is a Bare Board? In PCB terminology, the term “bare board” refers to the state of a PCB before it receives electronic components or through holes. A bare board consists of the PCB’s substrate, metal coating, conductive pathways and patterns. Some industry experts call a bare board a PCB and an assembled board a PCBA. What Is Bare Board Testing? Bare board testing involves testing the continuity and isolation of a bare circuit board’s connections. The

Flexible Substrate

Today’s technology consists of complex internal pieces that transmit numerous signals between the user commands and the system memory. As devices become smaller and more advanced, manufacturers require materials that can handle the stresses and demands of various conditions and uses. In decades past, technology was limited by rigid inner-parts that could buckle under intense levels of stress. In settings where there was too much heat or vibration, any device that contained a printed circuit board (PCB) could easily cease to function. Recently, however, technology has greatly improved thanks to the introduction of flexible substrates. Table of Content What Is a Flexible Substrate? Flexible Substrate Uses How Are Flexible Substrates Used in PCBs? Benefits of Flexible Substrates The Future of Flexible Substrates Flexible Substrate PCBs From Millennium Circuits What Is a Flexible Substrate?

Component Arrangement | 4. EMI Shielding | EMC Design From Millennium Circuits Limited | Overcoming PCB Electromagnetic Issues Electromagnetic issues consistently plague PCB designers. System design engineers must always monitor electromagnetic compatibility and interference. Unfortunately, even small design problems can result in electromagnetic difficulties. These issues are even more common than ever, with board designs shrinking and customers demanding higher speeds. The two primary issues at play are electromagnetic compatibility and electromagnetic interference. Electromagnetic compatibility, or EMC, involves the generation, propagation and reception of electromagnetic energy, generally through poor design. Electromagnetic interference, or EMI, refers to the unwanted and damaging effects of EMC, as well as electromagnetic interference from environmental sources. Too much EMI can result in a defective or damaged product. Any PCB designer should follow EMC design rules to minimize the
