In electronic assembly, printed circuit board is a key component. It is equipped with other electronic parts and connected to the circuit to provide a stable circuit working environment.
With increasing frequency, it becomes more and more difficult to control the phase consistency of printed circuit board materials. Accurately predicting the phase change of circuit board materials is not a simple or routine task.
How does PCBA improve product quality: (1) strengthen routine maintenance of machines, (2) requirements for equipment operators, and (3) develop measures to reduce or avoid errors
How to choose PCBA processing solder paste: (1) according to the value and use of pcb circuit board products,(2) according to the storage time of PCB and components and surface oxidation degree determines the activity of solder paste. (3) Select solder pa
in the manufacturing process of PCB, the three stages that must be tested are the inner layer after etching, the outer line after etching, and the finished product.
This is done by making multiple design changes to a small number of boards and then testing all variants before the next manufacturing run. These variants are for assembly only, and all bare plates are manufactured in a similar manner.
PCB industry is technology-intensive and capital-intensive, but it is still labor-intensive. A large number of automation equipment needs manual operation and assembly line operation. A medium-sized PCB enterprise has thousands of employees.
Learn about the factors that affect the appearance quality of the solder choke：1, printing: photoresistance welding ink screen printing process, blade flatness, environmental purification, screen printing using barrier tape and ink printing pressure will
bottom solder layer top solder layer drill guide, multilayer mechanical layer is to define the appearance of the entire PCB board, in fact, when we say the mechanical layer is referring to the overall structure of the PCB board.
In the production process, it can be prevented in the following ways: 1, moisture-proof storage of components, 2, select good quality solder paste, 3, adjust printing parameters of false welding and false welding problems, 4, control the welding time, 5,
Some circuit board shape is special, different shape, through the board can be more effective use of PCB substrate area, reduce waste, save costs.
PCB circuit board copper wire stripping is not good, PCB factories are said to be laminate problems, requiring its production factories to withstand losses.
