The following diagram shows the SPI standard mold polishing grade table, from which the polishing grades A~D in the mold industry originate. The A-grade claimed by 3D mold manufacturers also comes from here. There are four columns: ~ The first column is the grade code ~ The second column is the abrasive, tool, and polishing … Read more
Click the aboveblue text to follow us In embedded systems, the Serial Peripheral Interface (SPI) and its extensions (such as DSPI and QSPI) are widely used for high-speed communication with external devices (such as sensors, memory, LCD controllers, etc.). The main differences are as follows: 1 SPI SPI (Serial Peripheral Interface) is a full-duplex synchronous … Read more
Did you know? The smartphones, smartwatches, washing machines, and even cars we use every day all contain an “invisible brain”—the embedded system. The microcomputers that allow developers to easily create various smart gadgets are quietly changing the world. This all began over 60 years ago. In the 1960s, the prototype of embedded systems appeared in … Read more
The actuator is a device with controllable deformation capabilities and is considered the “heart” of miniature robots. A research team from Tsinghua University has recently developed a film-like miniature actuator that allows miniature robots to achieve continuous shape changes and “lock” specific action forms, enhancing their adaptability to various environments. The researchers stated that using … Read more

In data centers, pluggable optical transceivers convert electronic bits into photons, transmitting them to various corners of the room and then converting them back into electronic signals, making it a critical technology for controlling massive amounts of data in artificial intelligence. However, this technology consumes a significant amount of power. According to Nvidia, in a … Read more
“ The U.S. blockade on chip exports to China has made NVIDIA CEO Jensen Huang anxious, as he is well aware of the current level of domestic computing power in China. Recently, Huawei launched the AI computing cluster solution CloudMatrix 384, which may seem similar to others at first glance, but a closer analysis reveals … Read more
Overview This chapter will introduce the four basic processes used in wafer manufacturing to form electrical components of integrated circuits on the surface and within the wafer. The circuit design process traces from functional diagrams to the production of photomasks and mask plates. The characteristics and terminology of wafers and chips are described in detail. … Read more
