The latest upgraded special circuit board printer PS-6090PE is mainly used for screen printing of high-precision circuit boards.
     As we all know, precision circuit board, usually its line error must be controlled within 0.01mm, ordinary pneumatically controlled flat screen printer is difficult to meet the requirements. All-electrically controlled screen printers have much higher print stability because they do not have air pressure fluctuations. PS series high-precision screen printer has the following structure:
1) Precision Grinding Plane Workbench: Only the workbench after grinding machine has high flatness, the circuit board will not warp and deform in the printing process;
2) The movement of the frame up and down and the scraper scraping are controlled by a linear guide rail, and the accuracy is much higher than the screen printing machine controlled by the guide shaft;
3) The use of computer control and man-machine interface control system provides reliable guarantee of stability and practicality.
4) The worktable is designed with precise displacement function to ensure that the silver paste remaining on the screen can be completely transferred to the surface of the substrate, the squeegee function is increased, and the print-scratch-scratch function is printed.
5 The machine's squeegee device is controlled by servo motor and the squeegee speed is more uniform.
