In order to avoid such problems, the following detailed coping strategies can be adopted: Substrate selectionThe choice of material directly determines the basic bending performance of flex board. In terms of substrates, polyimide (PI) and polyester (PET) are commonly
High speed digital pcb is circuit boards that can support high speed digital signal transmission, and are usually used in scenarios where the frequency of digital logic circuits reaches or exceeds 45MHz-50MHz, or where the delay of digital signals in circuits on the transmission line is greater than 1/2 rise time. Compared to traditional analogue
Leadless chip carrier refers to a chip substrate material that does not contain lead. Traditional chip carriers often use leaded materials because leaded materials have high plasticity and are easy to process during manufacturing, but leaded chips are harmful to the environment and the human body. Leadless chip carrier is widely used in the manufacture
PCB board assembly processing, there may be a variety of defects, these defects can be categorised as the following major aspects, designed to improve product quality and reduce the defective rate. Welding defectsWelding is a key part of PCB board assembly processing, common welding defects include: False soldering (Dry Joints/Cold Solder): refers to incomplete solder

What is a chipset? A chipset is a processor that consists of multiple chips. Each chip in a chipset may be produced by a different manufacturer. These individual chipsets are combined together to form a processor using a complex connection system. Chipset processors can take advantage of the latest chip manufacturing technology to reduce the
Ceramic substrates and PCBs play an important role in the electronics industry, each with unique material properties, manufacturing processes and application areas. Ceramic substrate is a ceramic material made of electronic substrates, belonging to the inorganic materials, usually with alumina (Al2O3), aluminium nitride (AlN) and silicon nitride (Si3N4) as the main component, ceramic substrate has
What is dual inline package? Dual inline package (DIP) is a type of integrated circuit package whose main feature is that the integrated circuit chip is mounted on two parallel rows of metal pins. This type of package is simple, easy to produce and maintain, so it is widely used in the electronics industry. Dual
The ball grid array socket is an adapter that allows for pluggable mounting without directly soldering BGA-packaged integrated circuits (ICs) to the test substrate. By connecting the solder balls of the IC to the pads of the test substrate via the BGA socket, the risk of poor contact (e.g. open or short circuit) and IC
The design layout of a camera pcb board is a central aspect of ensuring camera performance, reliability and stability. An optimised layout can effectively reduce signal interference, improve signal integrity, and improve thermal management. Camera PCB Board Wiring GuideThe LVCMOS signal alignment needs to be away from the differential lines to prevent the LVCMOS line
The camera motherboard, also called the camera pcb board, is one of the core components inside the camera and contains the camera’s processor. Memory. Interface chip. Sensor control chip and other important components. The role of the camera motherboard is to control and manage the various functions and operations of the camera, so that the
Hybrid Bonding is an advanced IC packaging technology used to achieve high-density, high-performance interconnections between different chips. The key feature of this technology is to replace the traditional bump or solder ball (bump) interconnections with direct copper-to-copper connections, which enables ultra-fine pitch stacking and packaging in a very small space for the purpose of three-dimensional
Hybrid bonding is an emerging packaging technology that combines the features of inter-chip bonding and intra-chip bonding. It utilises different bonding techniques to achieve interconnections between wafers and package substrates or within wafers to meet the needs of high-performance integrated circuits with complex interconnect structures. There are two common types of hybrid bonding: W2W can
