SFP stands for Small Form-factor Pluggsable, which is a small pluggable optical module interface standard, commonly used in Gigabit Ethernet, fiber optic communication and other fields. The SFP module is small in size, suitable for dense layout, with hot-swapp...

Basic introduction to wire bonding Wire bonding is an important process in the semiconductor packaging process. It uses heat, pressure, and ultrasonic energy to tightly weld metal wires to substrate pads through bonding tools, thereby achieving electrical int...

400Hz is the power frequency used by most aircraft. Aircraft use AC generators to generate electricity, providing stable and efficient power for avionics equipment, onboard systems, cockpit equipment, auxiliary power units, etc. Why do most aviation power supplies use 400Hz frequency instead of 50 or 60Hz?

With the rapid rise of cloud computing and big data, data centers and telecom operators have higher and higher requirements for the transmission rate of optical modules. Since 1998, optical modules have been continuously upgraded towards higher rates and smaller packages. Optical modules generally use technical solutions such as increasing the number of wavelengths, increasing the number of signal transmission channels, and increasing the single-channel rate to achieve higher transmission rates for optical modules. This article briefly introduces these three technical solutions.

On the morning of June 26 (afternoon of June 25, local time in the United States), during the Sensors Converge (formerly Sensor Expo), one of the world's three major sensor exhibitions, the organizers Sensors Converge and Fierce Electronics announced the list of the 2024 Best of Sensors Awards.

Coaxial cable is a kind of wire and signal transmission line, which is generally made of four layers of materials: the innermost is a conductive copper wire, and the outer layer of the wire is surrounded by a layer of plastic, which serves as an insulator and dielectric 

The platinum resistance temperature sensor measures temperature by using the property that the resistance of metal platinum changes with temperature.  

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.
