What is the first inspection of pcba boards? The first inspection of PCBA boards is to inspect the first batch or the first few batches of products produced after each shift/production line is put into production during the production process. This work is also called the first inspection because it is a specific sample collected…

PCB design copper plating is a very important part of circuit board design. What is PCB copper plating? It is to fill the idle space in the non-wiring area on the PCB with solid copper. The significance of copper plating is to reduce the ground impedance and improve the anti-interference ability; reduce the voltage drop,…

5G represents the latest and greatest in wireless technology, and both design and manufacturing will be challenging, and of course circuit board materials will be challenging, because it will operate at many different frequencies, such as 6 GHz and below, as well as millimeter wave frequencies (typically 30 GHz and above). It will also combine…

With high-speed signal transmission, high-speed PCB design has higher requirements. Impedance control is a conventional design of high-speed PCB design. There will be processing errors in more than a dozen processes of PCB processing. At present, the impedance control of conventional board factories is within 10% error. In theory, the smaller the value, the better….

The widespread use of embedded vision (EV) systems has become ubiquitous, with advanced driver assistance systems (ADAS), machine vision, medical imaging, augmented reality, and many other applications all requiring an embedded system platform. However, while adopting EV systems can bring obvious advantages to the end application, it is also incumbent on developers to ensure that…

Basic concepts of FPGA and CPLD 1.CPLD CPLD is mainly composed of a programmable interconnect matrix unit around a programmable logic macro cell (LMC). The LMC logic structure is relatively complex and has a complex I/O unit interconnection structure. Users can generate specific circuit structures according to their needs to complete certain functions. Since the…

Providing Higher Performance Solutions for Fast-Growing Edge AI Applications Edge AI applications such as presence detection and object counting are growing in popularity, but designers are increasingly demanding low power and small form factor edge AI solutions without compromising performance. The latest release of Lattice’s sensAI technology portfolio, available for ECP5 and iCE40 UltraPlus FPGAs,…

As applications such as data centers, high-performance computers, medical imaging, precision layout traces, specialized PCB materials, form factor constraints, and thermal management expand, the demand for FPGAs is rising. In the past, hardware designers would opt for a “chip down” architecture, selecting a specific silicon device for the application and developing a fully customized board….

Innovative FPGA Technology Enables Low-Power, Modular, Small-Size USB Solutions USB technology development faces unique challenges, mainly due to the need to achieve robust interconnect, high speed, and power management within a constrained device form factor. Various device compatibility issues, varying data transfer speeds, and requirements for low latency and low power consumption put additional pressure…

What is differential signal Differential transmission is a signal transmission technology. Different from the traditional method of one signal line and one ground line, differential transmission transmits signals on both lines. The amplitudes of the two signals are equal, the phases are 180 degrees apart, and the polarities are opposite. The signal transmitted on these…
