High quality Printed boardfactory

Against the backdrop of accelerated iteration towards high performance,high integration,and high reliability in the electronics industry,the quality of printed circuit boards,as electronic devices,directly determines the performance and lifespan of end products.The process requirements for High quality Printed boardfactory mainly include the following aspects:
1.Film quality:High quality Printed boardfactory require good film quality,neat and opaque dot edges.The color separation film and the printing ink used should use the same color scale.
2.Exposure and screen stretching:When the positive image film is exposed on a glass plate,the stretched screen should be parallel to the image axis.If there is a turtle pattern,the screen needs to be rotated until the turtle pattern disappears,usually by turning it 7°.Using the same size and stable aluminum mesh frame,the tension of the mesh should be uniform and consistent.
3.Scraper and ink return knife:A well ground scraper is crucial for High quality Printed boardfactory.The Shore hardness of the blade is approximately 70,and the scraper should be set at a 75°angle.The ink return knife should not be installed too low to prevent excessive ink from filling the film plate.
4.Ink selection:Use High quality Printed boardfactory,and finer screens require ink with darker colors.When using UV ink,the screen thickness should not exceed 5um,and printing should be done in the color sequence of cyan,magenta,yellow,and black.
5.Color management:Using CMYK four-color mode for printing to ensure color consistency and accuracy.Use a color management system(CMS)for color correction and matching to reduce color deviation.
6.Branches and Levels:Full and smooth branches are key,and the transition between branches should be natural,without blurring or overlapping.Printed materials should have rich layers,smooth color transitions,and no obvious jumps or breaks.
7.Overprinting and positioning:Accurate overprinting is one of the key evaluation criteria.The overprinting error between various patterns and text should be within a certain range(such as 0.1mm or 0.3mm)to ensure the overall beauty and consistency of the printed product.
8.Cleanliness and clarity of printed sheets:Printed sheets should be free of wrinkles,grease,paste,stains,and other defects.The text lines should be smooth,with clear and complete edges,without any damage or deformation.
The manufacturing of High quality Printed boardfactory is a challenge to precision,materials,and craftsmanship.From signal integrity simulation in the design phase,to nanoscale etching control in the manufacturing process,to atomic level defect analysis in the detection process,every step needs to aim for zero defects.With the explosion of technologies such as the Internet of Things,High quality Printed boardfactory will evolve towards higher density,higher frequency,and High quality Printed boardfactory.Only by continuously breaking through process boundaries can we stand undefeated in this electronic cornerstone competition.
