1.PCB wiring and layout isolation criteria: strong and weak current isolation, large and small voltage isolation, high and low frequency isolation, and input and output isolation. The demarcation standard is one order of magnitude difference. The isolation method includes: the space is far away and the ground wire is separated. 2. The crystal oscillator should […]

January 11th, 2021, Santa Clara, California, USA Ambarella (hereinafter referred to as “AMBA Semiconductor”, NASDAQ: AMBA, a semiconductor company focusing on artificial intelligence vision) announced the launch of CV5, the latest chip in CVflow® series. This artificial intelligence vision processor can support 8K video recording or 4K video stream recording with four independent image inputs. […]

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 […]

Single-Chip Microcomputer For novices, electromagnetic interference may not pay much attention to the influence of circuit design on the input and output of the design itself, but for an electronic engineer, it is self-evident. It is not only related to the ability and accuracy of MCU in control, but also related to the competition of […]

1、 Preface At present, high-speed PCB design is widely used in the fields of communication, computer, graphics and image processing, etc. All high-tech value-added electronic product designs are pursuing the characteristics of low power consumption, low electromagnetic radiation, high reliability, miniaturization and light weight, etc. In order to achieve the above goals, via hole design […]

Nanjing PCB design power supply noise The common interference source in the circuit comes from the power supply, and this interference signal is usually introduced through the power supply pin of the active device. For example, the timing diagram of A/D converter output in is shown in. The sampling speed of A/D converter is 40ksps, […]

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 […]
