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...

How to make a noise-free infrared obstacle detection

By Hesam Moshiri, Anson BaoAn obstacle detection unit is an essential part of a variety of projects, such as robotics and security applications. The infrared sensors are widely used for these types of applications. The main drawback of some circuit designs is that the detection units are sensitive to the outside lights and react unstable or noisy.In this project, we selected a proper IR receiving component and designed the circuit in a way to act as stable as possible. Also, you can adjust the s...

How to make a variable step-down DC to DC converter using TPS54331

By Hesam Moshiri and Anson Bao.Almost in any circuit design, building at least one regulation stage is necessary. Two power supply design options are available, which are linear and switching. The linear regulators are easy to build but inefficient, especially when there is a high difference between the input voltage and the desired output voltage. Also, by increasing the regulator output current, the efficiency also decreases. Both of these problems are easily visible in terms of heat dissipati...
