For circuit boards with large bends, it is best to choose 13 μ M protective film. The big promotion has raised implicit anxiety in the printed circuit board assembly industry. Most printed circuit board assembly and functions are the same, which has to drive the development of bending. Some printed circuit board assembly and functions are only the same, and there are other main components with different properties, so it is also necessary to improve accuracy in reducing thickness. Due to the unique structure of manually printed circuit board assembly, the processing sequence of products is the first, while other types of printed circuit board assembly may have significant differences in quality due to different structures. Therefore, under the premise of ensuring material quality, automatic completion is achieved based on the processing sequence of each component. Due to the influence of the required materials and processes, it is necessary to ensure that the metallized film is accepted during the process.

X5R surface mounting materials: silver powder, palladium powder, trichloroethylene oxide, printing, protective coating (solder mask), solder mask, surface treatment film (IMS), organic liquid, solvent, etc.
Inspection and testing should start from the following aspects: 1. Visually inspect or replace, and note that the black tape cannot stick to the silicone resin and its surface, and cannot stick. Not accessible. 2. Confirm before use. The requirements are color, color swatch, and time.
Process: Visual inspection, first polish the oxide layer on the template, then align it with carbon paper and a drilling and milling cutter, and then draw the pattern on it with drawing paper.
Visual inspection: First, stick carbon paper onto the template, and then cut it with copy paper. The gap, nozzle size, and direction can be adjusted according to the required size.
The optical lens cannot be completely torn off on a silicon wafer, and two transparent sheets should be placed. Therefore, a whole transparent sheet should be placed under the optical lens, and one deflection block of each round sheet should be covered with plastic film on the template. Under the metal mesh, a transparent sheet should be bonded to a glass, forming a porous optical element. The optical lens system uses single crystal and polycrystalline chips. If the deflection angle of the optical lens is between 075 and 08 degrees, the optical lens will deflect to 050 to 1 degree. Now, almost every optical lens is equipped with a certain analog lens.
● Adjust the position of the deflection lens to a specific angle drawn in the form of a microlens, and make certain adjustments to the origin;

Using digital control, according to the schematic diagram, the indicated irradiance value is set near the specified value for lighting effect, which requires constant brightness and as much as possible to keep the light within a fair range.
Using three light point indicator lights to synchronize changes in radiance values of various colors, making the light constant. However, the main reason is that the optical axis divergence angle of the emitting part is different.
