EMC stands for Electromagnetic compatibility, which means that a device is compatible with (i.e., no interference is caused by) its electromagnetic (EM) environment. It does not emit levels of EM energy that generate electromagnetic interference (EMI) in other devices in the vicinity. Electromagnetic interference (EMI) is the interference caused by one electrical or electronic device […]

10 straightforward ways to reduce PCB assembly costs without compromising PCB quality
by Ken Ghadia, Sales Engineer, TechnoTronix It is difficult to build a quality product at the lowest cost. The quality of a PCB depends on the competence of its design for assembly, testing, repair, reliability, manufacturing, and yield. Several factors impact the cost of a PCB assembly. However, the designers can consider certain factors that […]
From designing to operating an RF PCB: The complete guide
by Ken Ghadia, Sales Engineer, TechnoTronix Radio Frequency (RF) PCBs are very high-speed circuits operating at frequencies in the range of 100MHz and above, typically from 500MHz to 2 GHz. RF PCBs are the backbone of wireless networks, high-tech gadgets like smartphones, smart TVs, etc. Also, RF PCBs are used in automotive, medical equipment, military, […]
Top ten tips for nailing your PCB silkscreen design
By Suresh Patel, Sales Engineer,Mer-Mar Electronics Silkscreen represents the outer layers of a PCB that include text-based readable information such as component reference designator, test points, company logos, PCB part number and version number, etc. This is necessary for circuit board assembly, rework and debug support. The silkscreen ink is different from the regular printing […]
Tolerance analysis distinguishes prototypes from production units
It’s not enough to model and simulate circuit behavior – you also have to investigate the effects of component variations from their nominal values due to unavoidable tolerances. There’s a semi-serious quip that scientists can build one of anything – but just one; it takes engineers and production experts to build it again and again […]
Optical links for spacecraft, Part 2: Projects and progress
Using laser-sourced light beams rather than wireless RF to link spacecraft with Earth offers the possibility of a significant increase in data rates. Still, there are significant technical challenges to the concept. The previous part of the article established the need for higher-speed data links to spacecraft and their missions and looked at some of […]
Optical links for spacecraft, Part 1: The throughput limitation
Using laser-sourced light beams rather than wireless RF to link spacecraft with Earth offers the possibility of a significant increase in data rates. Still, there are significant technical challenges to the concept. Scientists, engineers, and researchers communicating with spacecraft have a problem: there’s so much data coming from these spacecraft – and to send to […]
4 free PCB design tools every PCB engineer should use
by Ken Ghadia, Production Manager, TechnoTronix PCB manufacturing process is quite expensive and needs a diligent design tool to be used. There are several PCB designs tools available in the industry for free download. It’s always suggested to use the latest tools available in the market, and the free tool should be simple to use […]
The PC-board atomic clock, Part 3: The CSAC cesium physics cell
Atomic clocks have shrunk from room-sized assemblies down to PC-board mountable modules, admittedly with lower performance than their big siblings but still far better than crystal-based timing alternatives. Every engineer knows that developing a viable design and product is not just a matter of theorizing a design, identifying the constituent components, or building a single […]
The PC-board atomic clock, Part 2: The CSAC design
Atomic clocks have shrunk from room-sized assemblies down to PC-board mountable modules, admittedly with lower performance than their big siblings but still far better than crystal-based timing alternatives. Engineering is largely about tradeoffs and constraints, and atomic clocks are no exception to this situation. As these clocks are being designed into smaller packages through innovations, […]
