Introduction:Miniaturization and multi-function of products are the main driving force for the development of electronic industry. Printed circuit board is the most common electronic assembly platform. These include rigid or flexible polymer substrates and ceramic substrates for metal wiring. Typically, various components and subsystems are mounted on the board surface. However, in order to reduce the number of components on the surface of the printed circuit board, researchers are constantly st...

Introduction:Traditional rigid-flex PCB materials include rigid materials and flexible materials. The current production method is usually to carry on the pattern plating for the rigid substrates and flexible substrates, and then laminating the rigid substrates and flexible substrates together by using the adhesion agent. The materials of the adhesion agent are usually made of non-flowing prepregs. Flexible materials are expensive and costly to make. At present, the cost of multilayer rigid-flex...

In addition to having a strong hands-on ability and a passionate heart, Maker also has a must-have skill – “Arduino Board”. From grotesque hardware gadgets to tens of millions of dollars in commercial products Pebble smartwatches and Makerbot 3D printers start with such an inconspicuous Arduino board. "Fifty years ago, people who wrote the software needed to wear a white apron to know everything about semiconductors. Now? Even my mother can program."

Thomas McKahan is a long-time software and hardware tinkerer, beginning with Apple BASIC and 555 timers and working up to embedded Linux and system design. Currently, he made a new open-source hardware Obsidian ESP32, which is an Espressif ESP32-based board in the familiar form factor of popular single-board computers like Raspberry Pi. This allows you to use a wide variety of ready-made Raspberry Pi peripherals (or other peripherals) with the Arduino IDE, Espressif IDF, or MicroPython. The Rasp...

1. Determine the number of layers of the PCBBoard size and the number of routing layers need to be determined early in the design process. If the design requires the use of high-density ball grid array (BGA) components, the minimum number of routing layers required for routing these devices must be considered. The number of routing layers and the stack-up method directly affect the routing and impedance of the printed routing. The size of the board helps determine the stacking and line width to ...

We know that there may be some problems in the data exchange of each sub-module of the circuit system so that the signal can not be normally and circulated in high quality. For example, sometimes the working sequence of the circuit sub-modules is deviated (such as CPU and peripherals) or The respective signal types are inconsistent (such as the sensor detects the optical signal), etc., then we should consider the corresponding interface to deal with this problem well. The following is a descript...

This article will explain how to place the inductance of the switching power supply on the PCB design. First, let's look at this question: Where should the coil be placed?Switching regulators for voltage conversion use inductors to temporarily store energy. These inductors are typically very large in size and must be placed in the printed circuit board (PCB) layout of the switching regulator. This task is not difficult, because the current through the inductor may change, but not instantaneously...

The PCB is support for electronic components and is a carrier for electrical connection of electronic components, mainly for supporting and interconnecting. From the outside, the outer layer of the board has three main colors: gold, silver, and light red. Classified by price: gold is the most expensive, silver is second, light red is the cheapest. However, the circuit inside the board is mainly pure copper, which is bare copper.Why are there precious metals on the PCB?PCB as a support for electr...

And the surface treatment process will affect the production, assembly and end use of the PCB. The use occasion of five common surface treatment processes will be described below.Hot Air Solder Level(HASL)HASL has been dominant in PCB surface treatment processes. In the 1980s, more than three-quarters of PCBs used HASL, but the industry has been reducing the use of hot air leveling processe...
