Background knowledge

With the rapid development of consumer electronics, electronic devices are trending toward being "smaller, lighter, and thinner," a shift that drives continuous advancements in circuit board and connector technologies. Differential measurement technology not only serves as the quality "gatekeeper" for circuit board connectors but also forms the core foundation for achieving precision in electronic manufacturing.

In the early stages of the circuit board connector manufacturing industry, companies primarily used contact-based measuring tools like micrometers and dial indicators for segment difference detection due to lower precision requirements. These manual methods proved inefficient and inadequate for modern production line batch testing needs. As connector precision standards increased.

the limitations of traditional contact-based measurement became increasingly apparent. Against this backdrop, 3D industrial cameras emerged as the key technological solution, achieving precision breakthroughs from millimeter-level to nanometer-level accuracy to overcome these detection challenges.
