It can be divided into coated holes and non-coated holes according to whether it participates in electrical connection. Coated holes are involved in PCB electrical connection, and non-coated holes are not involved in PCB electrical connection.
On November 16, 1904, British scientist John Ambrose Fleming for his invention of the vacuum tube Fleming valve, applied for a patent, which marked the birth of the first vacuum tube in human history, and the world has since entered the electronic age.
The purpose is to make electronic equipment can not only suppress all kinds of external interference, so that electronic equipment can work normally in the specific electromagnetic environment, but also reduce the electromagnetic interference of electroni
While many orders are flowing into Southeast Asia because of the pandemic, they are also facing the impact of the pandemic, high inflation, volatile energy and food markets, and internal developments in some ASEAN countries are also at the core of domesti
Under the two major variables of China-Us trade friction and China's epidemic containment policy, PCB manufacturers in Taiwan have an urgent sense of finding another production base outside Taiwan and China.
From the current situation, only our country has recovered the supply of products in a short time, accelerating the trend of domestic replacement of PCB industry.
From 4G upgrade to 5G, communication base station required PCB quantity and price rise. Due to the high-frequency microwave characteristics of 5G, the base station density is higher than that of 4G base stations.
Many friends do not know how to charge for SMT processing. kingford SMT processing charge details are summarized as follows, and how to control components in SMT processing factory
The signal integrity problems of PCB mainly include signal reflection, crosstalk, signal delay and timing error.
It has been proved that the reliability of electronic equipment will be adversely affected even if the circuit diagram is designed correctly and the printed circuit board is not designed properlyAt present, the printed circuit board is still used as the m
Flexible circuit boards are mainly used in some sophisticated products, mobile phones, computers, digital cameras. Flexible circuit boards have great advantages over ordinary circuit boards, light weight, and can be bent.
There are many other factors that can affect proper coating of the PCB, including failure to clean the components before coating, failure to remove the original tri-guard paint from the surface, electrostatic discharge, and possibly even poor construction
