AI Technical Summary

Technical Problem

The prior art is difficult to accurately detect whether a single damp sensitive element is damp, resulting in a popcorn effect that may occur in subsequent patch processes, causing economic losses.

Method used

A moisture-sensitive element is designed, including a moisture-sensitive indicator unit, which consists of a moisture-absorbing dielectric material and anode metal. It absorbs water vapor through the moisture-absorbing dielectric material and causes electrochemical corrosion of the anode metal to indicate whether the element is at risk of moisture.

Benefits of technology

Accurate detection of whether a single moisture-sensitive element is damp, timely identify the moisture-affected element, reduce the occurrence of popcorn effect, improve assembly yield, and reduce production costs.
