The chips designed by HiSilicon cover a wide range, including wifi networks, fixed networks, digital media and other fields, but the most concerned and highly concerned ones are processor chips, including mobile phone processor SoC, server chips and its AI chips. On the technical level and threshold, the mobile phone with processor is obviously the […]

1. Brief introduction, blind holes and embedded fillers are mainly made of high-density and small microplates. Purpose depends on saving circuit space, so as to reduce PCB volume, such as mobile phone board. Second, classification: 1). Laser drilling, 1. the reason for drilling with laser: a. customer data requires drilling with laser; B because the […]

Loongson 1F chip is a cost-effective single-chip system based on GS232 processor core, which can be widely used in industrial control, home gateway, information appliances, medical devices and security applications. Loongson 1F is realized by SMIC 0.13 micron process and packaged in Wire Bond BGA448. Loongson 1F chip features: Integrated with a GS232 dual-launch Loongson […]

Domestic Feiteng has reached the level of international mainstream processors a few years ago. When Feiteng 2000 appeared, the opportunity of Feiteng appeared. Without a strong software background, the development of domestic cpu is slow, and it is impossible to develop effectively for a long time. It is very difficult to rely on China’s current […]

In order to improve and ensure the high-quality welding of electronic circuits, and prevent false welding and virtual welding in circuit welding, it is the key to correctly operate the soldering iron and reasonably select soldering tin and flux, and the treatment of the lead pins of the electronic components to be welded, the proper […]

Tianjin Feiteng Information Technology Co., Ltd., a subsidiary of China Electronics, is a fast-growing Chinese chip design enterprise, which is mainly engaged in the design, production, sales and service of high-performance and low-power integrated circuit chips, providing users with safe and reliable CPU, ASIC, SoC and other chip products, IP products and system-level solutions based […]

Electronic component surface cleaning and dust removal treatment When plasma technology is applied to circuit board cleaning, because the particles in plasma have a very high speed, it can effectively remove the impurity particles attached to the surface, and its purification effect is better than that of conventional treatment systems. At the same time, plasma […]

In the ordinary PCB design, we will encounter all kinds of safe spacing problems, such as the spacing between vias and pads, the spacing between traces, and so on, which we should consider. In PCB design, we divide these spaces into two categories: Electrical spacing Non-electrical safety spacing I. PCB design electrical safety spacing 1. […]

1. Spacing between patches The spacing between chip components is a problem that engineers must pay attention to in layout. If the spacing is too small, it is very difficult to print solder paste and avoid soldering. Suggested distances are as follows Device distance requirements between patches: Same device: ≥ 0.3mm. Heterogeneous devices: ≥0.13*h+0.3mm(h is […]
