Everything About THR Soldering

Würth Elektronik Watts Up Podcast ·

2022/05/19

Because of fast assembling and small sizes, designers are turning to surfance mount technology on their PCBs. Although there are still through-hole (THT) components that need to be soldered by Wave, Through-Hole Reflow (THR), allows designers to solder the Through-Hole Components together with the surfance mount parts in the Reflow Oven, thus canceling the whole Wave Soldering Process; saving time and money.

Filtering EMI on an RS-485 Interface: Part I

Würth Elektronik Watts Up Podcast ·

2022/05/05

By filtering directly at the interface, interference emissions, electrostatic discharges and fast transients bursts are prevented from entering the system; thus negatively influencing the operating performance. To verify the EMC properties of electrical systems, special tests are carried out in accredited EMC test laboratories, and if these tests are not passed, the application has to be revised. In order to simplify this process, an adapter stick was designed which contains a complete filter

Characterizing Methods for Flexible Absorber Sheets

Würth Elektronik Watts Up Podcast ·

2022/04/28

The most common means of solving electromagnetic noise problems is to shield the system with conductive materials, however, a large number of electronic devices have many parts that operate at high frequencies that can cause complex EMI problems that cannot be removed with conductive shielding. In today's podcast, we discuss ways to avoid these issues by using Flexible Absorber Sheets to supress unwanted high-frequency electromagnetic components.

2022/03/10

Energy-efficient devices are important components for saving resources and protecting the environment. The more efficient the electronics, the longer the battery service life for mobile devices, and in large-scale industrial and server installations with thousands of loads, the energy requirement is clearly reduced. The basis for energy-efficient devices is essentially influenced by the power supply unit. Download the complete Application Note, ANP031, at www.we-online.com/appnotes or click here.

EMC Passive Components for Automotive Applications

Würth Elektronik Watts Up Podcast ·

2022/03/03

Anymore, passive components that are only AEC-Q200 tested are not enough for the use in automotive application. Many more tests are needed for qualification for a good design and high quality component because without electronics, our vehicles would not operate. In this podcast, we discuss a few little design tips using passive components that are adequate enough to pass AEC-Q22 qualifications and complete a reliable automotive design.

Negative Input Resistance of Switching Regulators

Würth Elektronik Watts Up Podcast ·

2022/02/24

Even though a switching regulator may produce a constant output voltage at the end of the development phase, often, designers encounter unpleasant effects, such as unwanted oscillations, at the input. So why does the input of the switching regulator tend to oscillate under certain circumstances? In this podcast, we examine "negative" resistance and come to the understanding that the sign is based on a behavior which can be attributed to transients.

Whisker Growth and Mitigation

Würth Elektronik Watts Up Podcast ·

2022/02/03

A whisker is a crystalline structure of material that appears on tin surfaces. This well-known phenomenon was discovered in the early 1950's, and new legislative actions to avoid lead in electronic components has lead to the return of this whisker problem. These whiskers may reduce the isolation resistance and additional problems arise when the whiskers break and short the printed circuit board or some fine pitch components. In this podcast, we'll discuss some facts about understanding whisker

Influence of a Control Loop by an Output Filter

Würth Elektronik Watts Up Podcast ·

2022/01/13

Output filters are often used for noise suppression, which may have an influence on the control loop. To prevent output power losses, it may be necessary to compensate the control loop. No matter what switching regulator topology is used, as a result of the parasitic series resistor ESR, and the parasitic inductance ESL, of the output capacitor, the output current causes an undesired residual ripple.
