Before the patch processing in Xi ‘an SMT small batch patch processing factory, there is a process that is not particularly noticed, that is, baking. Some circuit boards in the electronics factory that don’t meet the requirements of Xi ‘an SMT chip processing due to long storage time and humidity in the storage environment can […]

Dot matrix board (universal circuit board/hole board) is a kind of printed circuit board (PCB) which is covered with pads according to the standard IC pitch (2.54mm) and can be inserted with components and connections according to one’s own wishes, commonly known as “hole board”. Compared with professional PCB plate making, hole plate has the […]

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 […]

With the rise of Internet of Things technology, it is more and more common for electronic products to be equipped with wireless communication function, and wireless communication technology is realized by RF circuit on PCB. Unfortunately, even PCB designers in Chengdu are often discouraged from RF circuit, because it will bring great design challenges and […]

The PCB is designed, sent to the board factory for processing, and the next step is “A” (Assembly), which is the process of welding and debugging as we often say. This process requires good soldering ability, correct use of testing and measuring instruments, and standardized debugging process. Finally, it is necessary to test the function […]

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, […]
