Printing

Short Circuit Occurrence in SMT Assembly Process and Resolution Part 2

Printing is crucial in PCB manufacturing, with steel squeegees recommended for IC printing with PTTCH less than or equal to 0.5, a 45-degree operating angle for the squeegee, a printing speed range of 10-20mm/s for fine pitch, and the use of contact or non-contact printing methods. A mounting height of 0-0.1mm is recommended for ICs with PTTCH of 0.55mm or less to prevent solder paste collapse, and backflow during reflow can be caused by factors such as excessive heating rate and fast flux wetting speed.

Explanation of Flexible Printed Circuit (FPC) Assembly Process

The FPC production process involves careful fixation on carrier boards, specific printing process, SMT, reflow soldering, and precise inspection, requiring attention to detail and specific considerations different from hard circuit boards. Dedicated carrier boards and careful handling are essential for quality and reliability.
