Used SMT QCA #184939 for sale

SMT QCA is a screen printing machine designed specifically for SMT (Surface Mount Technology) printed circuit board (PCB) assembly. It is a fully automated machine that uses stencils to accurately and quickly transfer patterns of solder paste onto PCBs. It can be used to print anything from the smallest 0402 components to the largest BGAs. The machine has a simple and reliable design which allows it to deliver consistent results over long production runs. It features a custom built Z-Axis mechanism which provides precise registration and repeatable accuracy of the stencil during the printing process. It includes an advanced vision equipment which enables it to precisely locate pads and features on the board being printed. The user can also select from different printing options, allowing them to choose the best method for a given component complexity. On the printing table, the machine can accommodate boards up to 510mm x 470mm in size, with a maximum component height of 30mm. The squeegee speed and pressure can be easily adjusted in-between passes, ensuring that the correct amount of paste is applied and increasing the precision of the printing process. For further reliability, a contact force sensor measures the paste deposit and adjusts the away speed of the squeegee to ensure it never contacts the component or PCB surface. The machine also has several additional features to help enhance productivity and efficiency. These include a live numerical feedback system, automatic calibration of the squeegee angle, and an auto-follow roller unit which maintains the correct component alignment during paste printing. An internal vacuum machine can also be used to remove excess paste after printing. All of these features, combined with its precise and repeatable results, make QCA the ideal choice for rapid and reliable SMT PCB printing requirements. Its ease of use, cost effectiveness and quick setup time make it the all-round ideal machine for high volume production environments.
