The selection and control of process parameters is one of the important factors affecting the quality of SMT processing. If the slight difference in temperature or time is not well controlled, it is easy to lead to poor tin penetration and other phenomena
FeedFeeding refers to feeding the components prepared in the preceding sequence in accordance with fixed procedures. At this stage, components need to be classified according to specifications, sizes, models, etc., and placed in the process location. Afte
Using outdated equipment and technology can result in too much or too little solder paste being applied to the pad, affecting the quality of the weld. Modern SMT plants usually use sophisticated equipment to apply the paste, such as printing presses and n
Patch short circuit refers to the electrical connection between two patches in the process of SMT patch processing. This problem may cause the circuit to work improperly and even cause equipment damage. The main reason for the short circuit of the patch i
SMT (Surface Mount Technology, surface mount Technology) is a technology that uses metal wires on the substrate to connect the electronic component directly to the substrate, rather than the traditional PTH (Through Hole Technology
Long track and zigzag track will affect the signal quality, resulting in signal distortion and interference. In order to avoid this situation, it is necessary to avoid the occurrence of too long and too curved. For some lines that need to be bent, excessi
Before SMT processing, the device and the board need to be processed. For components, it is necessary to carry out pre-preparation, including cleaning, stripping, processing, etc., to ensure that its quality meets the requirements. For PCB board
With the development of the production of printed led circuit boards in the direction of high precision and high density, the production of printed boards is more energy saving, emission reduction and environmental protection.
In addition, the tool point and processing sequence are selected well, so that the frame can maintain the maximum strength and the fastest speed. The choice is not good, the frame is easy to deform and make the PCB scrapped.
our PCB copying board research in the field of industrial robots needs to get rid of the drawbacks of traditional technology cloning, increase independent research and development efforts, take the international core technology as a reference for PCB revi
Add a blank signal layer near the center of the PCB stack. This approach minimizes layering unbalance and improves PCB quality. First, the odd-numbered layer is routed, and then a blank signal layer is added to mark the remaining layers.
In the environmental protection and clean zone, a number of innovative technologies and solutions applied to the "three wastes" (waste gas, wastewater, solid waste) treatment and resource recovery in the printed circuit board industry were also ...
