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...

3 important tips to PCB Typesetting Engineering

Define Typesetting EngineeringAfter your PCB layout is verified, it will be transformed into production data. To achieve the standard production, your layout data will be put into a standard panel with other layouts, the process is called typesetting. Three important tips you must read:1. We normally put the layout data with same solder mask, copper thickness, surface finish into one standard panel. 2. There will be a few HASL PCB that may be added to the standard panel with ENIG . This means t...

Opportunities and Challenges in the Development of Flexible Printed Circuit Board

Introduction:The development of flexible and rigid-flex PCB has been following the trend of being more layers, thinner and higher density. This trend will lead to the development of corresponding materials, processing, equipment, and motivate new technologies.Development Trend of New Materials and New Technologies:The innovation of flexible printed circuit board has a high dependence on the development of new materials. The innovation of insulating substrates, adhesives, foils, cladding layers, ...

Research on the Key Technology of PCB

Introduction:PCB is an important carrier of electronic components and an important circuit connecting component and has developed for a long time. According to the number of printed circuit board, PCB can be divided into single-side PCB, double-side PCB, multi-layer PCB. Until today, PCB has reached a fairly fine degree. Many improvements and optimization of PCB technologies have been born.High-Density Interconnection PCB:In the early 1990s, Japan and the United States pioneered the application ...

Key Points in Manufacturing Mechanical Blind-Via

For example, the figure below is the schematic diagram of a kind of mechanical blind through-hole PCB.Key Points of Manufacturing Process:The common manufacturing process:Transfer of inner layer patterns → Oxidation → Lamination → Drilling → PTH → Transfer of inner layer patterns → Oxidation → Lamination → Drilling → PTH → Transfer of ...

BGA Soldering Quality Detection Techniques by X-Ray Imaging

Introduction:BGA is a typical high-density packaging technology. Its characteristics are that the chip pins are distributed under the package in the form of spherical solder joints, which can make the device smaller, more pins, larger pin spacing, higher assembly rate of finished products and better electrical performance. Thus, the application of this kind of packaging method is more and more popular with the market.Currently, BGA soldering quality detection methods are very limited. Common det...

Analysis of the Methods of PCB Interconnection

Introduction:Electronic components and electromechanical components have electrical contacts, and the electrical connection between two discrete contacts becomes an interconnection. The electronic devices must be interconnected according to the circuit schematic diagram in order to achieve the predetermined function.As a part of the whole machine, a PCB generally cannot constitute an electronic product, and there must be the problem of external connection. For example, electrical connections are...

Materials of the High-Density Flexible Printed Circuit Boards

Introduction:The basic materials of high-density flexible PCB are substrates, conductors and cover layers (cladding). Substrates and conductors are usually laminated together to form copper clad laminates.Materials of Conductors:One of the main ways to achieve HDI flexible printed circuit boards is to use the thin, fine grained and low-profile copper foils. The standard copper foil used in conventional flexible printed circuit boards has always been RA foil, usually with a thickness of 1OZ (35um...
