Microwave Printed Circuit BoardConcept
A microwave circuit refers to any electrical or electronic device which operates on microwaves or uses microwaves for its operation. Some examples include radar systems, satellite dishes, cell phone towers, and TV antennas among others. Such circuits are designed to operate at specific frequencies or bandwidths so that they do not interfere with each other. A microwave is an electromagnetic wave of frequency between 1GHz and 30GHz. It falls under the band B, C, D, and E in IEEE standards. Microwaves occupy a large part of the entire RF spectrum as compared to other frequencies. The global demand for communication devices ...
Physical and Electrical Partitioning In PCB Design
Partitioning your design into physical and electrical sections can significantly reduce the number of through-holes you need in your PCB, thereby increasing production speed and cutting down on manufacturing costs. Here, we will explain what physical and electrical partitioning are how they are used in PCB design [1], and how to create effective partitioning schemes in your PCB designs. As you work on your next PCB design, you may be wondering how to implement physical and electrical partitioning in your design. These two factors are equally important to making the finished product successful, and both have a huge impact on the ...
Tips for RF PCB Design
With so many things to consider when designing an RF PCB, it can be hard to know where to start. How do you choose the right layout? What tools should you use to get the job done? RF PCB design has its own set of challenges that need to be addressed to get the most out of your circuit. There are some best practices you can use to ensure that your design will function optimally and run smoothly. The best PCB design [1] solution can be the difference between success and failure for your product, so you want to make sure ...
Stencils for SMT Assembly
A stencil mask is used in many manufacturing processes to make PCBs. This includes SMT stencils which are most commonly used in the process of making printed circuit boards. The use of these SMT assembly [1] varies based on the size and complexity of the board that they will be used on and the type of assembly machine that will be using them. For any SMT stencil application, solder paste should be used for paste dispensing. Advantages of using a stencil method are high yield rate, high accuracy, and repeatability, low labor cost, and good surface finish. The main disadvantage is ...
PCB Design, Planning, and Components Selection in Printed Circuit Boards
Designing a printed circuit board or PCB can become challenging because there are many factors to consider, including environmental conditions the PCB will be exposed to and the desired electrical components that the PCB will use. The best design, planning, and component selection bring the best-printed circuit boards. All electronic products contain printed circuit boards so considering the above elements is essential that we will discuss these elements in this article. Questions Regarding PCB Planning? A few questions to keep in mind when designing and planning a PCB include: How many layers do I want? What thickness of copper foil/laminate do I ...
