1. Xilinx ISE traditional FPGA design process The basic process of developing FPGA by using Xilinx ISE software includes code input, function simulation, synthesis, simulation after synthesis, implementation, simulation and verification after wiring and debugging after work. 1) circuit design or code input The design of FPGA can directly draw the schematic diagram, but in […]

Signal Integrity (SI) of high-speed PCB board design is abbreviated as SI. Definition: The quality of the signal on the signal line is the ability of the signal to respond with the correct timing and voltage in the circuit. High switching speed of integrated circuit chips (IC) or logic devices, incorrect layout of terminal elements […]

Llwinner A40i is an industrial processor developed in Quan Zhi, which has the characteristics of rich interfaces, low power consumption and high system integration. It is mainly used in industrial control products based on visual interaction. Quan Zhi A40I is based on Cortex™-A7 quad-core processor, with the highest frequency of 1.2GHz, integrated with Mali400 MP2 […]

It is the most skillful and limited in PCB design. Even engineers who have laid wires for more than ten years often feel that they can’t lay wires. Because they see all kinds of problems and know what consequences this wire will lead to when it is laid out, they don’t know how to lay […]

RK3399 is a low-power, high-performance application processor chip introduced by Ruixinwei, which is based on Big.Little architecture, that is, dual-core Cortex-A72 and quad-core Cortex-A53 combined architecture with independent NEON co-processors. It is mainly used in intelligent terminal devices such as computers, personal Internet mobile devices, VR and advertising machines. RK3399 has built-in multiple high-performance hardware […]

The production process of battery FPC is complicated, from cutting and drilling to packaging and shipping, there are more than 20 processes in the middle. In this long production process, according to customer demand, a variety of auxiliary materials will be used. The substrate of FPC is usually double-sided or single-sided copper foil, which is […]

Vias are one of the important components of multilayer printed circuit boards. The cost of drilling usually accounts for only 30% to 40% of the proofing cost of printed circuit boards. From this point of view, it is divided into two parts: a small part as the electrical connection between the layers; The other part […]

Why do I tell you again and again: don’t find those allegro factories to make multilayer boards! Don’t look for allegro factories to make multilayer boards! ! Don’t look for allegro factories to make multilayer boards! ! ! The reason why I am so determined is not because Allegro factory is not good for them, […]

“PCB is the provider of electrical connection of electronic components, and the layout of components is very important in PCB design, which will affect the final performance of products. If the layout and arrangement of components are unreasonable, the electrical and mechanical properties of the products will decrease, and it will also bring inconvenience to […]

The development of modern science and technology leads to the miniaturization of electronic components and the extensive application of SMT technology and equipment in electronic products. SMT manufacturing device has the characteristics of full automation, high precision and high speed. With the improvement of automation, higher requirements are put forward for PCB design. The PCB […]
