Digital Microscopy in QA/QC: Pushing the Limits of Inspection

Simple operation with no sacrifice in image quality

Highly sophisticated imaging can now be performed with the same ease of use you’d expect from your smartphone or tablet. Specifically designed for industrial QA/QC control labs, today’s digital microscopes can help you enhance your QC processes while allowing more team members to easily perform advanced imaging tasks.

A digital microscope combines the observation power of traditional microscopy with the convenience of today’s digital technology, achieving a new level of simplicity with no sacrifice in image quality. Even a novice operator can quickly master microscope operation and begin producing exceptional results.

Enhanced Performance, Increased Efficiency

With digital microscopy, the eyepiece is eliminated, greatly enhancing operator comfort. On-screen viewing also allows convenient group access and immediate result sharing.

Meeting a Variety of Demands

Digital microscopes are ideal for the observation, measurement, and analysis of electronic components, circuit boards, construction materials, semiconductors, medical devices, shielding components, and much more.

Here are some usage examples I found to be especially indicative of the advantages a digital microscope can deliver:

Pressure Sensor: Inspection of a Crimped Terminal

With a standard optical microscope, a dent in a crimped terminal is difficult to see due to shadowing (Fig. 1A). This is caused by the light beam hitting the slope of the crimped terminal.

With a digital microscope, MIX contrast provides ideal observation conditions by providing enough reflected light to the sensor by using two beams (Fig. 1B).

Multilayer Circuit Board: Observation of Inner Circuit

When performing this inspection with a traditional microscope, it is often impossible to image the inner pattern of the circuit board (Fig. 2A) because of the high reflectance pattern on the surface.

Using a digital microscope, a live image can be displayed using HDR observation to combine multiple images with different exposure times (Fig. 2B). This makes it possible to observe both bright and dark areas at the same time.

Decarbonized Structure: Observation of Texture Changes

The sample shown here here exhibits a white decarbonized section and an inner dark section on the surface, which cannot be clearly observed at the same time using a standard inverted microscope (Fig. 3A).

Using a digital microscope, an image with higher contrast can be obtained by creating multiple images at different exposures to clearly observe both the decarbonized structure and the inner structure at the same time (Fig. 3B).

Dental Tools: Confirmation of Appearance

Observation and inspection of dental tools are traditionally conducted by frequently changing the position of the sample. A digital microscope makes it easy to inspect samples that even lie on different planes (Fig. 4).

Figure 4: Olympus DSX100 microscope, 6x zoom, upright observation, HDR, EFI

With a digital microscope, a clear image of the sample can be obtained by combining images from different focal positions (Fig. 5).
