When talking about printed circuit boards, novices often confuse “PCB schematic diagram” with “PCB design document”, but in fact they refer to different things. Understanding the differences between them is the key to successful PCB manufacturing, so in order for beginners to do this better, this paper will break down the key differences between PCB […]

In PCB proofing, rational and effective use of components is an important guarantee for the stability of PCB performance and quality. So, what problems should be paid attention to when using components in PCB proofing process? 1. PCB proofing limits the output current to avoid locking effect of CMOS circuit; Lock-in effect means that there […]

1. print PCB circuit board. Print the drawn circuit board with transfer paper, and pay attention to the slippery side facing yourself. Generally, two circuit boards are printed, that is, two circuit boards are printed on a piece of paper. Among them, the printed circuit board with the best printing effect is selected. 2. Cut […]

Circuit board, which can be regarded as a miniature bearing platform, is an important carrier of integrated circuit. The appearance of PCB multilayer board allows the limited space to accommodate more and more complex circuits as much as possible. In addition, it also simplifies the difficulty of circuit layout on PCB to some extent. Many […]

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 […]
