UL, ISO and ITAR: Important Information About PCB Certifications

small circuit boards

UL, ISO & ITAR When it comes to printed circuit boards, there are certain standards in place that buyers look for. Experts may tell you to be sure to work with a UL PCB supplier, an ITAR registered supplier or an ISO PCB supplier. But what do these things really mean, and what exactly should you be looking for when seeking out quality printed circuit boards for your business? Here is some basic, useful information about these terms. UL PCB Standards Those seeking quality printed circuit boards may look for boards that are UL approved, such as a UL 796 PCB. Why? UL is short for Underwriters Laboratories, a global independent safety science company with over 100 years of expertise innovating safety solutions. UL is an accepted leader worldwide in testing, certification and standards development, with a goal to use safety science and safety engineering to promote safe living and

 Guide to Reducing PCB Design Errors

Reduce PCB Design Errors Mistakes in your printed circuit board design can lead to increased costs for your engineers, designers and manufacturers while slowing your time to get to market. That hurts your revenue and can lead to significant problems in your department. No one wants to experience those concerns, so we’ve put together this quick look at some ways to reduce PCB design errors. We’re addressing the most common concerns, but remember to always work with an engineering team whose focus is to limit PCB design errors in the production phase. Look for Component Concerns Component placement can cause some major design headaches if there are mistakes. Placement needs to take electrical noise, thermal management and overall function into consideration. Make sure all your components and the overall board are sufficiently able to function. The design isn’t too difficult in most cases, and there is some leeway in your

PCBs for LED Lighting Industry

PCBs and Their Applications in the LED Lighting Industry Printed circuit boards, or PCBs, are everywhere in our technology-based society. Everything from computers to medical equipment to cars contains these PCBs in one form or another. However, not all PCBs are the same— many of them use different designs or materials to suit a unique purpose. The base material is especially important for the circuit board, which helps determine how effectively the circuit board transfers heat. Some applications require specific properties in their circuit boards. This is especially true for temperature-sensitive applications, one of which is LED lighting. The LED lighting industry is expanding rapidly in response to increased interest in the more efficient and cost-effective lighting method, but much of the functionality of LED lights depends on the temperature of its system. For many companies, the solution to this problem is in aluminum-based PCBs. To help you understand why

Long Printed Circuit Boards

Long Printed Circuit Boards Modern wireless applications need robust antennas, and that often means needing a long printed circuit board to integrate and support those applications. The design of an antenna can make or break your application, but relying on long PCBs can help you get the job done right. The antenna can be built right onto your long printed circuit board with copper optimization designs boosting its capabilities. Antennas tend to be an area where design can very difficult, and working with experts can help you optimize the impact your board will have. Get the best antenna by teaming up with the best engineers and manufacturers. Antenna Application Use Wireless antennas are used in almost every modern device that arrives in our homes. From cellphones and coffee makers to new washers and TVs, there’s an antenna, and it’s probably created right onto the circuit board. Printed circuit board antenna

PCB Measling and Delamination

PCB Assembly Boards

What Is Measling and Delamination? Circular white spots and small hole-like areas that appear in your printed circuit boards are typically measling and delamination errors that can occur during the production or use of PCBs. These errors can interfere with normal operations and may ruin your PCB. It is easy to control for these errors when identified, and leading PCB brands like MCL can even design your boards in a way that limits delamination and measling errors. What Is the Difference? While measling and delamination may appear similar, there are some noteworthy differences to keep in mind. Delamination is when the layers of your PCB base materials experience a partial separation. This will cause gaps or bubbles that look like blisters. Delamination typically occurs in the production process when unwanted heat or humidity are present. Measling is the presence of white spots in the PCB weave interior. They signal a

Guide to PCB Issues

Guide to PCB Issues Printed circuit boards (PCB) are essential components of many electrical devices today, connecting different components to one another through a complex array of circuits. These boards consist of several layers of copper traces to make the connections, as well as plastics and other materials to protect those connections from the environment. The design and quality these PCBs directly affect how well the boards work in the final product, or whether they will work at all. The complexity of the PCB designing and manufacturing processes means there are numerous opportunities for PCB failure issues to arise. Some of these failures are a result of design oversights, such as insufficient clearances or incorrect measurements, which can negatively affect the functionality of the finished product. Others may result from problems in the manufacturing process, such as drilling errors or over-etching, which can be equally catastrophic. Fortunately, most of these
