Usually the same area, the more PCB layers, the more expensive the price. The design engineer should use as few layers as possible to complete the PCB design while ensuring the quality of the design signal.
It is critical for board designers to lay out their boards to create the best possible signal and power integrity. Components shall be placed in a good position for short and direct wiring. At the same time, the boards must be laid out so that all the net
Next, I will introduce the research and development process of PCBA products.1. Market research; 2. Prototype and interaction design; 3. Hardware development - main chip confirmation
The basic working conditions of PCBA patch after processing are as follows: 1. Working conditions: Temperature: 18℃ to 28℃, humidity: 35% ~ 75%; 2. 2. Operation object: all PCbas; 3. Operator: with certain general SMT and DIP welding status identification
As an important part of PCBA, SMT processing has a direct impact on product quality. SMT processing includes multiple processes. How to standardize each process so as to post perfect PCBA
Take your choice of PCB substrate quality：1. Gold plate, 2.OSP plate, 3. Silver plate, 4. Gold plate, 6. Tin-spraying plate
Layout is divided into two ways, one is interactive layout, the other is automatic layout, is generally adjusted on the basis of automatic layout with interactive layout, in the layout can be redistributed according to the situation of the line, the two g
The size of SMT steel mesh thickness is mainly determined by the spacing of PCB circuit board welding components, if the spacing is small, the selection of thinner SMT steel mesh. If the spacing is large, choose the thickness of SMT steel mesh.
Because some standard thickness of the circuit board is not the same size, so the customer can measure some checks, according to their own product thickness and specifications, and then the light and color, in the external circuit board and ink cover, fol
1. Establish a total quality (TQC) network within the enterprise to provide timely quality feedback.Two: In order to ensure the accurate inspection and maintenance of testing equipment and equipment, it is necessary to inspect and maintain the products, t
The components in the circuit module should adopt the principle of nearby concentration, and the digital circuit and the analog circuit should be separated at the same time.
There are two main variants to consider, linear power supplies and switched mode power supplies. These are all challenges for PCB layout.
