South Korean media said that the semiconductor industry in South Korea has begun to deal with China's semiconductor chase, trying to get rid of the technology gap with China. South Korea's semiconductor giants samsung electronics and SK hynix have begun mass production of memory chips with the world's top technology, accelerating the gap with China. [...]
For capacitance installation, the first thing to mention is the installation distance. The capacitance with the smallest capacitance has the highest resonant frequency and the decoupling radius is the smallest, so it is placed closest to the chip. The larger ones can be a little bit further away, and the outermost ones have the largest [...]
However, due to the fierce market price competition, the cost of PCB board material is also in the rising trend, and more and more manufacturers monopolize the market with low price in order to enhance the core competitiveness. However, behind these ultra-low prices, is to reduce the cost of materials and process manufacturing costs to [...]
Making PCB board is not a simple process to complete the board, drill a hole on the components. PCB production is not difficult, the difficult is to finish the production of fault troubleshooting. Whether it is a personal hobbyist or an industrial engineer, it is quite a headache for PCB circuit board debugging problems, just [...]
Via hole is also known as the conduction hole. In order to meet the customer's requirements, the through hole must be plugged in the PCB process. Through practice, it is found that in the process of plug hole, if the traditional aluminum sheet plug hole technology is changed and the white mesh is used to [...]
Circuit board factory can find and eliminate waste and reduce cost in FPC flexible circuit board production process through lean production management mode to analyze value stream map. Lean production can help circuit board factory to re-examine all activities, processes and links of FPC flexible circuit board production, remove unnecessary production links, so as to [...]
Integrated circuit is a kind of micro-electronic device or component. Using a certain process, the required transistors, resistors, capacitors, inductors and other components and wiring interconnect in a circuit, the production of a small piece or a few small pieces of semiconductor chip or dielectric substrate, and then encapsulated in a shell, become a required [...]
The first is finger row electroplating It is often necessary to coat a rare metal on a plate edge connector, a plate edge protruding contact or a goldfinger to provide lower contact resistance and higher wear resistance. This technique is called finger row electroplating or projection electroplating. Gold plating is often the inner layer of [...]
In the process of PCB processing, it is inevitable that there will be defective products, which may be caused by machine errors or human factors. For example, sometimes there will be an abnormal condition called hole breaking state, the cause of which shall be analyzed on a case-by-case basis. If the state of hole breaking [...]
When troubleshooting nonfunctional or nonperforming circuits, engineers can often run simulations or other analysis tools to consider circuits from a schematic level. If these methods don't solve the problem, even the best engineers can get stuck, frustrated, or confused. I've been through this before. To avoid going down similar dead ends, here's a simple but [...]
