会社のニュース Why is Regular Replacement of SMT Machine Parts Essential for Production Yields ?

The goal of any SMT production line is to achieve the highest possible production yield—the number of good circuit boards produced versus the total number started. Over time, however, even the best SMT Machine Parts will experience wear and tear. This begs the question: why is the regular replacement of these parts so essential for maintaining high production yields, and what are the risks of using worn parts?

Regular replacement of SMT Machine Parts is a critical, proactive maintenance strategy that prevents catastrophic failures and ensures consistent quality. Worn-out parts, even if they appear to be functioning, can have a domino effect of negative consequences on a production line.

The risks of using worn parts include:

Increased Placement Errors: Worn nozzles and feeders can lose their precision, leading to component misalignment or tombstoning, where a component stands up on one end. These errors create faulty boards that must be discarded, directly reducing the production yield.

Frequent Machine Stops: A worn feeder may jam, or a faulty sensor may trigger an error. These small failures cause the entire production line to stop, leading to costly downtime and lost production.

Component Damage: A worn nozzle with a damaged tip can crush or scratch delicate components, leading to a high rate of component loss.

Reduced Speed: Worn parts can slow down the machine's operation as the system struggles to compensate for mechanical inaccuracies, reducing the overall production speed and efficiency.

By proactively replacing parts like nozzles, filters, and feeder components at scheduled intervals, a manufacturer can prevent these issues. This investment in maintenance ensures the SMT machine operates at peak performance, maximizing production yields and guaranteeing the highest quality final product.
