A Powerful 30A DC Motor Driver using Power Mosfets [PWM Controlled, Half Bridge]

DC motors are everywhere, from hobby applications to robotics and industrial areas. Therefore there is wide usage and request for suitable and powerful DC motor drivers. In this article, we will learn to build one. You can control it using a Microcontroller, an Arduino, a Raspberry Pi or even a standalone PWM generator chip. By using a proper heatsink and cooling methods, this circuit can handle currents up to 30A.[1]: Circuit AnalysisThe heart of the circuit is an IR2104 MOSFET driver chip [1]....

How to prevent the PCB from being bended and warped when get through the reflow furnace

Everyone knows that PCBs are easy to be bended or warped when get through the reflow furnace. So how to avoid this situation, here are some advices for you.1. Reduce the effect of temperature on PCB board stress Since the "temperature" is the main source of stress in the board, as long as the temperature of the reflow furnace is lowered or slow the speed of warming up and cooling down in the reflow furnace, the board bending and the board warping can be greatly reduced. However, there ...

Thermoelectric Separation Technology of Copper Core PCB

What is the Thermoelectric Separation Substrate?The circuit part and the thermal layer part of the substrate are on different circuit layers, and the thermal layer part directly contacts the heat dissipation part of the lamp bead to achieve the best heat dissipation (zero thermal resistance) effect. And the material of the substrate is generally the copper substrate. Advantages:1. Selecting the copper substrate: the density is high, the substrate itself has strong heat ...

Get to know the Multi-level /Step Stencil

What is Multi-level /Step Stencil?Partial STEP-UP Stencil and partial STEP-DOWN Stencil are carried out on the steel sheet to make the same printing on the same stencil, so that different areas can obtain different thicknesses of solder paste. According to the performance of components, the size of connection end and the lands, it can accurately control the amount of solder paste which applied to the different components are accurately controlled to make the solder paste printing process efficie...

4 Main Types of Plating Methods in PCB production

There are four main types of plating methods in PCB (Printed Circuit Board) production: finger-plated plating, through-hole plating, reel linkage selective plating and brushing plating. Here's a brief introduction: 1. Finger-plated platingRare metals need to be plated on the board edge connectors, board edge joint or gold fingers to provide lower contact resistance and higher abrasive resistance. This technique is known as finger-plated or protruding partial plating. Gold is often plated on ...

How to build an isolated digital AC dimmer using Arduino

By Hesam Moshiri, Anson BaoDisclaimer: This circuit is connected directly to the mains voltage. You must care about all safety precautions before using the device. AC loads are everywhere around us because at least home appliances are supplied with the mains power. Therefore, we always face the situations that we want to have full control (dimming) over an AC load such as a lamp, a motor, vacuum cleaner … etc. We should know that controlling an AC load is not identical with a DC load. So we shou...
