At present, PCB products on the market are mainly divided into three types in terms of materials: ordinary substrates, metal substrates and ceramic substrates. Next, the circuit board factory will share with you: what are the classification and advantages of metal substrates? 1、 Classification of metal substrates: There are three kinds of metal substrates: aluminum [...]
Blind buried hole circuit boards are prone to reflow in the production process, causing plate bending and warping, affecting the product qualification rate. Then, how to reduce the risk of bending and deformation in the production of blind buried hole circuit boards? 1. Reduce the influence of temperature on the stress of blind buried hole [...]
What are the types and precautions of PCB inks and what are their functions? Concept of PCB ink PCB ink refers to the ink used in printedcircuitboard (PCB). The important physical characteristics are the viscosity, thixotropy and fineness of the ink. These physical properties need to be known to improve the ability to use ink. [...]
Switching regulators for voltage conversion usually use inductors to store energy temporarily. These inductors are usually very large in size and must be positioned in the printed circuit board (PCB) layout of switching regulators. This task is not difficult because the current through the inductor may change, but not instantaneously. It may be continuous and [...]
The AMC23C12 is an isolated window comparator with a short response time. The open-drain output is separated from the input circuitry by an isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced galvanic isolation of up to 5 kVRMS according to VDE V 0884-11 and UL1577, and supports [...]
1、 Solder paste stage 1.1 solder paste Solder paste (or solder paste) is the key material for welding. As Wikipedia, it is a kind of material used in the manufacturing of printed circuit boards to connect surface mount components to pads on the board The paste is initially sticky. After heating, it is pasted on [...]
Whether it is for personal use or commercial applications, the defects of flexible circuit boards will cause serious adverse consequences. So, how to quickly detect the fault of flexible circuit board? 1. Determine fault location Once there are signs of problems, the next step is to track and determine the location until the defect is [...]
market? About the future, whiPrinted circuit board (PCB) is known as the "mother of electronic products". It can realize the interconnection between electronic components and play the role of relay transmission. It is the support of electronic components. According to the survey of Yidu data, the global PCB output value in 2021 was about US [...]
