PCB proofing of circuit board
After the PCB size is determined, the pendulum position of the special component is determined. According to the function unit, the layout of all components of the circuit board.

How can pcb design reduce costs
As the trend of electronic design continues to evolve, the core elements of functionality, usability and price remain the most important factors for engineers. This has always been CadSoft's strength. CadSoft provides engineers with functional, low-cost s
Simple double-sided PCB board copying method
The technical realization process of PCB copying board is simple. Firstly, the circuit board of the copying board shall be scanned, the location of components shall be recorded, the components shall be removed and made into material list, and the material
What are the commonly used PCB design software?
In PCB circuit board design software, it generally includes schematic design and PCB design two modules; Now commonly used software are AltiumProtel series, Altium Designer 6.0, Mentor Graphics PADS series, Cadence OrCAD and P-CAD2006PCB design software.
What materials and classification do pcb circuit boards have?
PCB copper-clad plate is the basic material of electronics industry, mainly used for processing and manufacturing printed circuit board (PCB), and pcb production process and material affect its price
Why should pcb circuit boards do impedance
Impedance refers to the resistance and reactance parameters, because PCB circuit board bottom plug into consideration of electrical conductivity and signal transmission performance, so it is necessary to impedance as low as possible, resistivity should be
Circuit board processing how to choose PCB board
The life and performance of circuit board machining depend on the selection of PCB board. Fiberglass FR4 is the most common material used for PCB substrates. For flexible PCBS, use Clapton or equivalent plastic. PCBS made from cheaper materials such as ep
PCB contamination by improper disposal
The production and manufacturing process of PCB will produce a variety of pollutants such as waste water, waste gas and solid waste, which will have a certain impact on the environment. Disposal of expired printed circuit boards will also cause pollution.
Multilayer PCB circuit processing
On SMT circuit board, solder joints and components are on the same plane of the circuit board, so in SMT processing PCB, through holes are only used to connect the wires on both sides of the circuit board, the number of holes is much less, and the diamete
PCBA functional test
In order to save production cost and improve production efficiency, some PCBA functional tests now use fully automatic testing schemes. For some simple PCBA functional tests of the tested board, manual or semi-automatic testing schemes are still adopted i
The design of millimeter wave PCB to consider the factors input
The transition to millimetre waves poses a number of challenges for the printed circuit industry, primarily conductor geometry and materials, as the shorter wavelengths reduce the feature size and amplify the relative tolerances inherent in PCB manufactur
PCB raw material tolerance and variation
Local peaks and valleys may be produced, resulting in highly irregular effective substrates after pressing. The manufacture of printed circuit boards introduces local differences in etching/plating flow patterns depending on the direction.
