Basics of Flexible Printed Circuit Board Design
Flexible PCBs have revolutionized many industries, especially the medical sector, in form-fitting monitoring and biometric patches. These devices are becoming increasingly vital. What is the technology behind them? Nearly every electronic device, including phones, TVs, and appliances, are equipped with a printed circuit board (PCB). These boards are made up of laminated conductive insulated layers. They serve two purposes: they house electronic components in designated locations on the outer layers and provide reliable electrical connections between component terminals. Electronic components, resistors, capacitors, microcontrollers, interfaces, etc., are electronically connected via traces, planes, and other features using a chemical etching process that deposits copper layers…
New PCB Design Curriculum for Electrical Engineers
College Level PCB Design Courses New college-level courses for electrical engineers are now available, focusing on PCB design. EMA Design Automation, Cadence, and Rochester Institute of Technology collaborated to develop online and in-person courses taught by experts. The aim is to provide engineers with skills, talent, and abilities to tackle the constantly evolving technology world. The team developed these courses based on the old book “Hitchhiker’s Guide to PCB Design.” The curriculum was designed to bridge the skills gap, focusing on critical topics such as design for manufacturability, an understanding of how to use multiple PCB design tools, and the fundamentals of both design and manufacturing. Manny Marcano, president and CEO of EMA, said, “EMA is committed to supporting the…
The State of Autorouting in PCB Design
Autorouting in PCB Design PCB design begins with a schematic. The schematic can be a simple paper drawing on simple boards or captured in a CAD program for more complex boards, such as Altium or OrCAD. The connections on the PCB should be identical to the schematic, but while the schematic is readable, the PCB design is arranged to be functional. As a result, there is rarely any visible correlation between the schematic and the layout. PCB design can be performed manually (using a CAD tool such as Altium Designer, PADs, or Allegro) or in combination with an Autorouter. The best results are always achieved using manual routing because the design engineer can exercise better judgment in arranging circuitry than an autorouter program. Many autorouted boards are often utterly illogical in…
7 Reasons Why You Should Pay Attention to Silkscreen in Your PCB Design
7 Reasons Why Silkscreen is Important in PCB Design A silkscreen layer is often deemed unimportant in the whole PCB assembly process because it has no direct impact on the electrical functionality of a PCB. As a result, little attention is usually given to the silkscreen compared to the tremendous value it brings and the importance it holds. Silkscreen serves as a means of providing information about a PCB. It is mainly used for PCB identification and labeling, with zero connection to the electrical functionality of the PCB. It is generally one of the last steps in PCB design. The silkscreen refers to the printed text on a PCB board containing information regarding the PCB assembly process, especially in the placement of components such as the references, identifiers, and the company…
Why PCB Design Services are the Job of the Future
PCB design services are the jobs of the future. Here are three reasons why: Many electronic devices include printed circuit boards (PCBs). They are like cells for organisms. They are used in almost every electronic product. The need for PCB design services continues to grow with the constant advancement of technology. Although PCBs will utilize the same types of technologies in each board, how these technologies are combined can create difficulties in the PCB design process. For example, many boards now utilize a sizable layer count, vias, DDR4 memory, impedance control, etc. Tying these together on a PCB in a world demanding smaller footprints can be pretty complex. PCB designers must have an intricate understanding of each type of technology to succeed. In reality, PCB designers play…
