Temperature sensors are used in automobiles, consumer electronics, household appliances and other products. According to the characteristics of temperature sensing elements, they are mainly divided into thermistors, thermocouples, and resistance temperature detectors as shown in Figure 1. Their measurement temperature range, measurement accuracy, and cost are different.

Wedge is an important tool for wire bonding in the semiconductor packaging process. This article describes the phenomenon of wedge aging. The study shows that the causes of wedge aging are the wear of the wedge blade end face and the influence of the blade end face product. The wear of the wedge blade end face is irreversible. The wedge blade end face product can be removed by cleaning methods, so that the wedge can continue to be used before it fails due to wear.

With the expansion of global air transportation and the rapid development of aviation technology, a stable power system has become a key factor in ensuring the continuous operation of aircraft. International aviation units have developed a series of aviation regulations, such as MIL-STD-704F, RTCA DO160G, ABD0100, GJB181A, etc., aimed at standardizing the power supply characteristics of aircraft electrical equipment to ensure that the aircraft can still operate normally under various power supply conditions.    

Tire pressure sensor is an intelligent device that can monitor the tire pressure of car tires. It can monitor the tire pressure situation in real time and transmit the data to the vehicle's information system, providing timely feedback on tire pressure status for drivers. In addition to its application in automotive safety, tire pressure sensors can also play an important role in energy conservation and environmental protection.

Programmable power supplies usually consist of a host and a control panel, and users can set and operate the power supply through the buttons and touch screen on the control panel.It enables users to flexibly change parameters such as output voltage, current, and power through digital control technology, thereby meeting various complex power supply requirements.

Coaxial cable is a type of electrical wire and signal transmission line, usually made up of four layers of material: the innermost layer is a conductive copper wire, and the outer layer of the wire is surrounded by a layer of plastic (used as an insulator or dielectric). There is also a thin mesh of conductive material (usually copper or alloy) outside the insulator, and the outer layer of the conductive material is used as the outer skin,as shown in Figure 1,Figure 2 shows the cross-section of a coaxial cable.

This article introduces the structure, materials, and selection ideas of commonly used bonding wedge for micro assembly wire bonding.The splitter, also known as the steel nozzle and the vertical needle, is an important component of wire bonding in the semiconductor packaging process, which generally includes cleaning, device chip sintering, wire bonding, sealing cap and other processes.

With the popularity of 5G, big data, blockchain, cloud computing, the Internet of Things and the rise of artificial intelligence in recent years, higher and higher requirements have also been put forward for the rate of data transmission, making the optical module industry chain get very much attention this year.

As an important power and signal transmission tool, the cable is more and more widely used in various extreme environments. In various applications, cable sheath materials play an important role in protecting internal components of cables from environmental factors such as moisture, heat, and mechanical stress.

As the core component of optical communication systems, optical modules integrate precise optical and circuit components inside, making them highly sensitive to the reception and transmission of optical signals.
