Where is the core of quality improvement? Is it technology or equipment? No, the core of quality improvement is to change people. So, what are the basic actions and ways to solve quality problems? Today, let's get to know about it with the circuit board editor of Shenzhen United circuit automobile~ First, the standardization and [...]
The global PCB market is a big business, which is expected to grow from $60billion in 2020 to $75billion in 2027. Celus, which is headquartered in Germany, wants to use this field to create an automated platform that spans the entire circuit board design process from conception to printed circuit board. In order to accelerate [...]
1. Working principle: Press the work switch and the motor runs. If the motor is in idle state, the motor can only work for 5S and then stop automatically. If it is in juice state, the motor will continue to work for 90s and then stop. 2. Parameter description Battery: 3.7V lithium battery Working voltage: [...]
According to the report of Taiwan media "Economic Daily" on June 26, Hon Hai Slovak factory mainly produces consumer electronic products, including LCD and OLED TVs, and PCBs manufactured using SMT technology and used in TVs. The factory announced its intention to enter the automotive field two years ago. Last year, it expanded its automotive [...]
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 [...]
