PCB are one of the core components of electronic devices, and silk screen adhesion is one of the important factors affecting the quality and accuracy of PCB. The adhesion of text not only affects the appearance of the PCB, but also directly affects the reliability of the PCB. Therefore, it is necessary for us to carefully study the factors that affect the adhesion of silk screen. Material is one of the important factors affecting the adhesion of text. Generally speaking, ink printing is used for PCB handwriting. If the ink used is poor, it will affect the adhesion of the handwriting. You can choose high-quality printing ink to ensure the adhesion of the text. Printing pressure is also one of the factors affecting the adhesion of text. Excessive or insufficient pressure can have a negative impact on the adhesion of handwriting. Therefore, when using a printing machine for text printing, the printing pressure should be adjusted to ensure reasonable adhesion of the text. Cleanliness is one of the important factors affecting the adhesion of PCB text. During the manufacturing process of PCB, it is necessary to ensure that the surface of the PCB is clean. If there are dirt, oil stains, and other stains on the surface of the PCB, it will affect the adhesion of the PCB. In addition, environmental factors can also affect the adhesion of PCB text. In humid environments, the adhesion of the text is adversely affected, and may even cause problems such as blurring and detachment of the handwriting. When environmental conditions such as temperature and humidity change, the adhesion on the surface of the PCB will also change. Therefore, in the manufacturing and use process of PCB, it is necessary to control environmental factors reasonably to ensure that the text can continue to adhere to the surface of the PCB. There are many factors that affect the adhesion of PCB text, including cleanliness, stickiness, surface treatment, and environmental factors. Only by reasonably controlling these factors can we ensure that the text on the PCB can be permanently attached to it, thereby ensuring the quality and service life of the PCB. Sihui Fuji selects renowned ink suppliers in the industry to control the quality of materials from the source, avoiding the problem of text detachment due to material issues. In addition, we will closely monitor the environment and status of the substrate during processing, eliminate any defective substrates present in the previous process, and ensure that all substrates used for text processing are good products, reducing the occurrence of defects during text processing. In terms of personnel skill training, we will regularly arrange research and development technicians to provide professional knowledge and theoretical training to employees on the job site, so that employees can have a comprehensive and in-depth understanding of the causes of text detachment and basic countermeasures from a theoretical perspective. Summarize and print out the key points and difficulties of text printing, and post them on site to make employees look clear at a glance.
