The feature of QFN without pins makes QFN can only be connected to the PCB pads through the device’s own grid. On the one hand, it cannot absorb the stress caused by thermal mismatch through the deformation of the pins. On the other hand, the grid is blocked by the device, which brings challenges to the detection and reliability of solder joints.
IC package is an essential component that houses and protects microchips. The package is designed to provide a physical and electrical connection between the chip and the printed circuit board (PCB). IC package is used in a wide range of electronic devices, from smartphones and laptops to cars and medical equipment. In this article, we will introduce its benefits, types, functions, etc. Keep reading!
The role of electronics test equipment is to measure various electrical parameters, such as current, voltage, cycle, electric power, power factor, resistance, etc. By measuring the values of these electrical parameters, the electrician can understand the technical performance , so as to make appropriate processing and necessary adjustments to ensure the normal operation of the circuit. Therefore, here are 7 commonly used electronics test equipment you should know.
