5 Tips to Find a Reliable Electronic Components Supplier

Technology is progressing at a fast pace, making more and more electronic components obsolete. New and innovative electronic components are making their way to the market, making it difficult for people to find End of Line (EOL) electronic components. And it does not help that the market is full of suppliers, including unethical ones that sell fake products to naïve buyers. People who want electronic components feel unsure where to start their search and which suppliers to trust to place their order. As a buyer, you must make informed decisions to make the right choice. Here are the tops tips to find a reliable electronic components supplier:

The Importance of EMI Shielding in Design

Designers play a crucial role in many of the products we use daily. Not only have they dreamt up many of the life-changing technology we take for granted, but they also work with engineers to improve the user experience of just about everything under the sun. However, today’s tech-heavy world means that designers must be cognizant of engineering challenges – such as electromagnetic interference (EMI). This can disrupt critical systems and functions of mobile devices, industrial equipment, cars, and even medical instruments. With that in mind, here is an overview of the importance of EMI shielding in design.

Have you used CAD-based data to run your manufacturing processes?

One of the decisive factors whether an Electronic Manufacturing Service (EMS) is accepted or not is the presence of Computer Aided Design data. But why? If you are involved in a modern manufacturing process you definitely need an Original Equipment Manufacturer (OEM) since this is confidential information and also the core of your overall design. This is the reason why you should submit your OEM to your EMS partner before stepping into the following manufacturing stages. This is the first milestone of a series of modern and detailed manufacturing processes. Are you having trouble transforming from 2D images to 3D images? You need an excellent quality CAD software for it. Every actual manufacturing process is a work of art presented by the designer, and the deciding factor is whether any equipment used can enable it to happen. You really need the CAD software to make your products meet the today’s standards.

Tips to improve your electronic designs

Electronic designs cover a wide array of technical options. In this post, we will cover some of the basics that will help you improve your electronic designs and make sure that you complete it successfully. Block diagram The first part of your design schematic is a block diagram. Block diagram should be an extract from the document showing the hardware design. This particular section is similar to outlining an essay. This is because it gives the design an overview of the architecture, and the reader gets a reference. If you want your block diagram to look great, make sure that you include page numbers in the schematic sections. Naming the nets This can be a time-consuming process, but if you want to state the purpose of every net, you need to name them. Apart from this, naming the nets will help you in debugging the program and allow simulation runs. There might be many experts telling you that naming every net is not essential, but you should consider it while creating every schematic.

USB Boost Single Multi Power Kit assembly

One of my projects (AVR DDS 2.0) requires multiple power supplies that could supply +12V, -12V, and 5V. Back then, I have constructed a simple transformer-based power source with few linear voltage regulators. It works fine but is powered from mains 220V, which is not the safest solution to squeeze in to box enclosure. Another option was using the ATX PC power supply, which is too big. Banggood has been offering pretty attractive power supply kit which has a voltage boost circuit that raises voltage level either from USB or from the 5-24V jack. Power supply kit has most of the voltages that you may need including + 12V, -12V, + 5V, -5V, and +3.3V. It is capable of outputting 300mA per channel. Total power is limited to 10W, which is not bad and can provide a short-term high current single output, but be sure to attach included heat sinks to protect ICs from overheating. It is advised to keep the output currents of each channel to less than 0.2A.

Electrical signal power and energy calculations by example

In electronics and signal processing, you have to deal with electrical signals. In many cases, you may need to calculate signal power and energy. Power and energy for DC In a standard situation, when DC power supply is applied to a known resistor or another device like an LED motor you can calculate its power very easy by applying Ohms law: If we run this device for time T then we can calculate total energy used: In some cases, you may not know the resistance of your circuit. In this case, you can measure the current flow. So your power formula can be transformed by using same Ohms law:

Ultrasound wave propagation and parameters

Ultrasound waves are acoustic pressure waves that interact with propagation media. Ultrasound visualization is typically based on wave reflectance from regions with different acoustic properties. When a wave meets different acoustic media, part of it transmits further while others reflect. This happens due to different acoustic impedance. The ration between reflected and transmitted energy purely depends on the difference in acoustic impedance in both regions. As you can see each material can be characterized by its acoustic impedance Z which is equal to ultrasound speed v and material density r.

Ultrasound waves and propagation

It has been more than 100 years since ultrasound has been used for analyzing materials and echolocation. A bit later, it was adapted for medical diagnostics. Ultrasound became popular and widespread due to the number of benefits. Probably one of the essential features is that it is non-destructive. The other is simplicity and precision. Of course, when we talk about price and simplicity we have X-ray or tomography in mind. Ultrasound can be used in many areas and environments. You can measure geometrical properties of internal structures and physical properties like density and tension. In medicine, ultrasound visualization is mainly used as a non-invasive medical imaging technique using high-frequency sound waves to produce images of internal body structures. It is commonly used to view and diagnose conditions related to pregnancy, the abdomen, and the heart. The images are created by transmitting sound waves into the body, which bounce off internal structures and are detected by a transducer, then processed by a computer to create real-time images. Ultrasound is generally considered safe and painless and does not involve ionizing radiation.

Benefits of using multiturn potentiometers

Potentiometers are common electronics components that convert rotary or linear motion in to change of resistance. They can be found anywhere where some adjustments are needed, volume control, and joysticks. You can dive into the long theory about potentiometers, how they are made, what materials are used, and what output characteristics they have regarding rotation angle. As an electronics hobbyist and probably pro, you usually deal with two common types of potentiometers – standard pots with knobs and trim potentiometers. The first group of potentiometers is used where the user has to access the potentiometer when he needs to change one or another parameter like sound volume or screen brightness. They usually are more prominent in size and can be mounted vertically or horizontally to board. Also, they have a panel mount with the nut. This type of potentiometers needs to be mechanically stronger and resistive material more durable due to frequent use.

Building simple constant current power LED driver

Usually, when we need to drive low power LEDs, we don’t care much about power losses. What we do we add a current limiting resistor, and that’s enough. For instance, for 20mA LED, we choose between 300Ω-1kΩ resistor when powering from 5V. But a different situation is with power LEDs. The currents are much more prominent here, like 1A and more. Adding a resistor to limit the current isn’t an option because power losses become significant. Here you need a constant current driver to drive it safely without wasting energy. It happens that I have Cree XR-E Q5 XLAPM-7090 LED lying around. It requires a 3.7V driving voltage and can take up to 1A current. There are several light intensities given at specific currents:
