UV-OM

Technical Concept |
Florescence penetration experiments are used mainly on small samples to examine things such as chip-level packaging. This analytical method was derived from the red dye penetration test, which is more suitable for the examination of larger components. For instance, red dye penetration test can be used to observe the condition of the welding on components.
However, when the samples are smaller, the penetration of the red dye becomes increasingly difficult to distinguish beneath the microscope. In contrast, even in small amounts, the florescent agent will emit a light that is distinct from that of the background when irradiated with UV light. Therefore, we can replace red dye with a fluorescent agent when observing the gaps in the welded joints of a sample.

Application |
Fluorescence analysis involves using fluorescent agents to permeate a sample under a vacuum then using UV-OM light to observe the fluorescent reaction of the sample.

1．Packaging Irregularities |
When the package paddle is suspected to be abnormal, the UV-OM is used to observe the fluorescent leakage area.

2．LED Fluorescence Distribution Observation |
LED fluorescence distribution observation is the inspection of the composition and quantity of different fluorescent particles.
