4 Solder Paste PCB Printing Steps Infographic

Solder paste printing is essential in surface mount technology (SMT) assembly, ensuring tiny components are correctly positioned on circuit boards for devices like smartphones and laptops. To start, power up the machine and computer, allowing all components to return to their home position and check for obstructions. Inspect the squeegee blade and template to prevent any potential clashes. Then, enter the PCB’s dimensions—length, width, and thickness—accurately in the software. Adjust the transport track width if necessary, place the PCB onto the track, and confirm it’s snugly fit.

The PCB’s position is crucial, so use automatic features to secure it, adjusting the height and clamping volume for a level setup. With everything in place, double-check the transport track height to prevent misalignment. The final step involves the squeegee moving back as the stencil aligns with the PCB, creating a clean, consistent print. Proper setup and calibration of the solder paste printer are vital for accuracy and reliability, setting the stage for successful SMT assembly.
