To make the electronic circuit get good performance, the layout of the components and the layout of the wires are very important. In order to design a PCB board with good quality and low cost, what principles need to be followed when determining the position of the components for PCB circuit board? PCB circuit boards…
PCB is a Printed Circuit Board. It’s an important electronic component, which is a support for electronic components and a carrier for electrical connections between electronic components. An electronics PCBA is a complete package; it has been fitted with all the necessary components(capacitors inductors, resistors, diodes, triodes, modules, and BGA’s) and is ready for deployment…
In modern, all electronic products are inseparable from PCB boards; different circuit boards have different applications, and their corresponding quality is also different. The PCB Manufacturing Classified by demand: ■ Enterprise-level user needs. Enterprise-level user needs are mainly concentrated in the fields of communication equipment, industrial control medical, and aerospace. Related PCB products often have…
PCB fabrication is prone to cause various problems of PCB Circuit Boards in a humid environment, such as short circuits, circuit board signal open circuits, and these failures. How to judge whether the PCB circuit board is wet? If the PCB circuit board is used in a humid environment, the air in this environment contains…
The PCBA Board Manufacturing Process Should Pay Attention to These Points: 1. BGA, chip capacitors, crystal oscillators, and other stress-sensitive devices are easily damaged by machinery or high temperature. Therefore, PCB manufacturers believe that when designing or strengthening equipment, they should be placed on a PCB with higher hardness, or some methods should be used…
One thing that is very common in SMT chip processing is electronic components. So how to replace SMD components in the circuit board processing process? First, prepare a temperature-controlled electric soldering iron with a ground wire. The width of the soldering iron tip should be equal to the metal end surface of the chip PCBA…
As we all know, as the fundamental part of electronics, printed circuit board assembly (PCB) has influenced our daily life in aspects. Household appliances, computers, digital devices, medical electrical equipment, military science, and almost all electrical equipment cannot work without PCBs. After a PCB is ready, the electronic components and parts can be assembled on…
We know that in high-speed PCB assembly manufacturing, seemingly simple holes often bring great negative effects to circuit board design. Therefore, in the design, we should try our best to do the following: 1. Considering both cost and signal quality, choose a reasonable hole size. For example, for the 6-10 layer memory module PCB design,…
Many newcomers who are just entering the industry have doubts about the color of PCB boards and do not know what color PCB bases are of high quality of the PCB board. In fact, PCB manufacturing mainly provides the interconnection between components, and its color has no direct relationship with performance and quality, and the…
What file should be provided when making PCB samples?The PCB manufacturer cannot work directly during the manufacturing process, nor can the PCB layout file be directly converted into the manufacturing instructions for the automated equipment. Most manufacturers will require some or all of the following PCB manufacturing documents: 1. Gerber, BOM, and site-specific documents in…
