Current Sense Resistors Lower PCB Temperatures

The flameproof BR Series open-element, radial-leaded current sense resistors raise their elements off of the PCB, allowing maximum heat transfers to the ambient air. They promise to lower PCB temperatures by as much as 20ºC compared to similar molded or ceramic housed components of similar size. An all-welded design enables an inductance of less than 10 nH and a current handling up to 70A. The components are available in resistance values as low as 2.5 milliohms, 1W, 3W, and 5W power ...

Is 3D Printing the Future?

What is 3D PrintingAlso known as desktop fabrication and additive manufacturing, 3D printing is a prototyping process where a real object is created from a 3D design. 3D printing techniques were originally designed in the 90s to create inexpensive prototype parts for industrial and automotive design work. However, now the costs are falling, 3D printing is finding its way into a variety of industries. How does it work?There are several different 3D printing methods. In additive manufacturing, 3 ...

Take a Fast Look at PCB Electronic Part

A printed circuit board or pcb, is a plate or pcb board used for placing the different elements that conform an electrical circuit that contains the electrical interconnections between them. The most simple printed circuit boards are the ones that contains copper tracks or interconnects pcb board only on one of its surfaces. These kinds of boards are known pcb board as 1 layer printed circuit board or 1 layer PCB. The most common PCB's manufactured pcb board today are the ones that contain 2 l...

Minimize crosstalk with optimized PCB routing technique

I. IntroductionToday, there are a number of high speed digital communication protocols applied in portable computing devices with compact PCB dimensions. Protocols such as PCIe, USB, and SATA have data throughput of gigabits per second and differential amplitudes of hundreds of millivolts. These high speed serial signals require proper routing on a PCB to minimize inter-pair crosstalk that could cause data corruption between the two ends of the channel. Crosstalk occurs when there is coupling o...

10 Tips for Streamlining PCB Thermal Design--A High-Level 'How To' Guide

Many aspects of a PCB’s performance are determined during detailed design, e.g. making a trace a specific length for timing reasons. Timing issues are also affected by temperature differences between components. Thermal issues with the PCB design are largely ‘locked in’ during the component (i.e. chip package) selection and layout phases. After this point only remedial actions are possible if components are found to run too hot. We advocate a top-down approach starting at the system or enclosu...

Using A Laser Printer To Make Your PCB Board

Anyone who knows me well will tell you that I am circuit board a true "do-it-yourselfer". My father instilled in me at a young age that PCB you can do anything you set your mind to’ attitude. So when I heard that it is possible to make your own PCB at home using a laser printer, photo paper and a regular household iron, I knew I had to find out just how to do it. As an aside, this idea reminds me of the 25-year-old law student at the University of Texas who earlier this circuit board year thoug...

PCB Materials Application Continue To Make Breakthroughs

To find the ideal balance between circuit board cost and performance for a given application. Let’s start at the beginning. The most common PCB fabrication material is FR-4. It is cost-effective, highly flexible, and mechanically strong with bond strengths at temperatures up to 130ºC. However, FR-4 does not work well for high-speed or high-frequency (greater than 1 GHz) applications circuit board where signal precision is critical and any signal loss has a significant impact on performance....
