Development prospects of automotive electronics PCBA production and processing
The current market situation of automotive electronics PCBA is that the pre-installation market is matched by the vehicle market itself, and the suppliers are generally subsidiaries or holding companies of their own companies.
Overview High Density Circuit Board HDI
Overview High Density Circuit Board HDI1 History of the boardThe name of the printed circuit board is derived from the English PCB (Printed Circuit Board), or it is also called PWB (Printed Wiring Board) in English. It replaces some early wire assembly pr
Electromagnetic compatibility in printed circuit board (PCB) development techniques
Electromagnetic compatibility in the design of printed circuit board (PCB) involves many factors, the following mainly from three parts to be elaborated, the specific selection to integrate various factors.
What are the basic components of a circuit board?
The semi-molten solder paste is placed on the circuit board by the steel mold, and then the SMD components are pasted on it, and it is welded on the circuit board by reflow welding
Application field of multi-layer circuit board
For high - level circuit board processing technology research literature, the industry is relatively few. This paper introduces material selection, laminated structure design, interlayer alignment, inner line production, pressing process, drilling process
High - level circuit board hub production process control
High TG, high speed, high frequency, thick copper, thin dielectric layer and other special materials are used in high-rise board, which puts forward high requirements for inner line fabrication and graphic size control.
Application of image recognition technology in precision test of printed circuit board
The image recognition technology is applied to the precise measurement of printed circuit boards. The test results show that the system has a high accuracy (0.6μm), which can meet the high precision measurement of printed circuit boards.
How to maintain PCB circuit boards to extend the service life?
With the rise of the electronic industry, circuit board production and development has become a more and more important part of PCB proofing a circuit board is not simple, easy to say.
PCB circuit board factory introduces PCB light curing
At present, for PCB curing, the most suitable use or UV light source, because UV light source has the characteristics of other mercury lamps do not have, just take the light source, UV light source is a cold light source, the curing principle is that the
How to calculate the cost and quotation of PCB circuit board
to see what is the surface treatment process, we commonly have: spray lead tin (hot air leveling), OSP(environmental protection board), spray pure tin, tin, silver, gold and so on, of course, the surface process is different, the price will be different.
What are the PCB circuit board wiring principles
Frame line as the basis of PCB circuit board contour processing, cutting processing can only be processed straight shape, special-shaped local available punch and milling machine processing.
