2 DSX Applications Electrical parts Pressure sensor/ Inspection of a crimped terminal A metal terminal at the end of a flexible pressure sensor. This terminal is crimped with a pattern. Embedded in gas or liquid pressure gauges Since poor crimping of terminals may cause a power distribution failure, inspection is required and images of defects need to be captured. An optical microscope is used, which requires additional adjustments including tilting the sample. Using a standard microscope, the dent of a crimped type terminal is often difficult to see due to shadowing. This is caused by the light beam hits the slope of the crimped terminal, and as a result, the sensor does not receive enough light back. MIX (bright-field and dark-field observation) contrast provides the ideal observation conditions by providing enough reflected light to the sensor by using two light beams. First, a light from above (bright-field) hits the flat bottom of the crimped terminal, and the second oblique illumination light beam (dark-field) hits the slope and removes the shadows. MPLFLN5XBDP, 1x zoom MIX observation, EFI Electrical parts Printed circuit board/ Inspection of electrodes and circuits Bare electrodes and laminated patterns on a flexible printed circuit. The patterns on the right-hand side of the image are laminated. Flexible printed circuit board for a printer Inspect the condition of the electrode surface and the laminated pattern in order to prevent a possible conductivity malfunction. The coated surface requires inspection. An optical microscope is currently used. Effective for the observation of the surface of the electrode when using bright-field illumination, but the surface of the laminated pattern cannot be observed. Inspection of the darker, laminate surface cannot be achieved using standard bright-field mode because it reflects the direct light. Using dark-field observation an effective image can be acquired. because of the oblique illumination. It is also possible to switch between bright-field and dark-field modes with the touch of a button. MPLFLN10XBDP, 2x zoom Dark-field observation 2

3 DSX Applications Electrical parts Multi-layer Circuit Board/ Observation of inner circuit Inner circuit of a multi-layer circuit board. This board is typically found in a personal computer To inspect whether there are any defects such as scratches, etc. on the surface pattern of the multi-layer circuit board. At the same time, confirm the inner pattern. An optical microscope is typically used but the issue is that the bright pattern on the surface is easily imaged but the inner pattern is not. Often when performing this inspection the inner pattern cannot be imaged. It is difficult to find almost any details about the inner pattern because of the high reflectance pattern on the surface which drives the camera's exposure. A live image can be displayed using HDR observation to combine multiple images with different exposure times. This makes it possible to observe both bright and dark areas at the same time. DSXPLFL3.6X, 2x zoom Upright observation, HDR Electrical parts Flexible printed circuit board/ Inspection of foiled circuit The sample is a flexible printed circuit that is laminated except for the end. Flexible printed circuit board for printer Inspect whether there are scratches, etc. in the foil circuit under the laminate layer. The sample must be inspected in a non-destructively. An optical microscope is used. A sharp image can not be obtained due to the affect of the laminate layer, blurring the image. 500µm When using bright-field illumination the circuit below the laminate layer cannot be sharply observed because of the coating, reflecting and blurring the image. Polarized light illumination provides a colored and high contrast image by using polarization properties of the material and also reduces reflection from the laminate layer. This allows you to achieve a sharp image of the circuit under the laminate layer without impact from the laminate coating. 500µm MPLFLN10XBDP, 1x zoom Polarized light observation 3

4 DSX Applications Material science Decarbonized Structure/ Observation of texture changes The sample exhibits a white decarbonized (ferrite) part and an inner dark (perlite) part on the surface which cannot be clearly observed at the same time using a conventional digital camera and depth of field. A test piece of polished metal in a resin block A standard test piece that is used to observe a metal structure. In order to determine whether heat processing was performed correctly, users observe the state of the decarbonization on the surface of the carbon steel. (Supplement) Decarbonizing makes inhomogeneous hardening and creates cracking. Parts with this kind of structure are defective because the life span of the parts becomes shorter and their mechanical performance is dramatically reduced. Using Fine HDR an image with higher contrast can be obtained by taking multiple images at different exposures to clearly observe both the carbonized structure and the inner structure. In addition, the blackened perlite structure can also be observed using EFI which removes depth of field limitations. Use an inverted microscope with bright-field illumination i XLMPLFLN10XDSX, 3x zoom Bright-field observation, Fine HDR, EFI Material science Fractured metal surface/ 3D observation Using the EFI function to obtain a clear image of the fractured surface despite unevenness, thus removing depth of field limitations. Tensile test piece. The material is CoCr alloy (cobalt chrome alloy). Dental alloy for artificial teeth and orthoprosthesis Assess the mechanical strength using a tensile test. In addition, the state of breakdown can be studied by observing the fractured surface. A stereo microscope is used. The unevenness of the surface can be visually observed by tilting the sample, but a sharp image of the surface cannot be achieved. MPLFLN5XBDP, 1x zoom MIX observation, EFI The 3D image function displays the fractured surface as a three dimensional image and makes it possible to clearly observe the unevenness and other conditions.

5 DSX Applications Automotive Automotive brake pad/ Observation of abrasion There are times when bright-field observation can not obtain a sharp image and the contrast of the sample is low. Research and Development The sample is cut from a used brake pad. Key component used in automotive industry. Observe the state of abrasion on the brake pad. In the past, asbestos was used but now that it is prohibited, the condition of the substitute fiber is being studied. 400µm The material responds to polarized illumination making it possible to acquire a color image with the fibers resolved. Using the DSX makes the application of polarized illumination simple and repeatable. A standard optical microscope has typically been used. Though it can be difficult to obtain a clear image by brightfield observation. Using Polarized light can improve this but it makes the operation more complicated and less repeatable. 400µm i MPLFLN10XBDP, 1.6x zoom Polarized light observation Machinery Diamond wheel/ Inspection of the distribution of abrasive grains Bright-field observation can not obtain bright image of abrasive grains. It is almost hard to see the surface condition. Disk-shaped diamond abrasive Diamond wheel used for compact grinding equipment. Used to deburr parts after processing. Visually inspect whether the abrasive grains are evenly distributed. The polished surface will become smooth and the diamond wheel will last longer if the grains are evenly distributed. Polarized light observation provides an image in color and with high contrast. This technique is particularly effective when observing minerals. It is also possible to switch between brightfield and polarized light observation with the touch of a button. An optical microscope or large magnifying glass are used.

6 DSX Applications Machinery Cutting Tool/ Review defects Top Picture: Precision drill made of high speed steel Bottom Picture: End mill made of carbon tool steel Machine tool for cutting and boring holes in metal Inspect the polished surface of the cutting tool and whether there are any defects before shipping. If there are any defects, an image of the defect must be recorded. A stereo microscope is typically used. Though it is difficult to find flaws in the polished surface and search for defects because the surface is so reflective. 500µm Flaws in a polished surface can be easily acquired using dark-field observation. In addition, the overall shape can be imaged using EFI mode to combine a focused image of both the area surrounding the drill and its center, making it simple to locate defects. MPLFLN10XBDP, 1x zoom Dark-filed observation, EFI Use dark-field observation to easily find defects. In addition, EFI mode can be used to favorably observe the condition of the defects, which helps in specifying the cause of the defects. 500µm MPLFLN10XBDP, 1x zoom Dark-field observation, EFI Machinery Gear used for Deceleration/ External inspection of overall part Bevelled gear made of steel. Used in the deceleration gears of a robot (automated machine on the manufacturing line) Visually inspect and record an image of the damaged areas on the gear. A stereo microscope is used. 5mm Using the panorama (or stitching) function, the DSX can obtain a high resolution image with a wide field of view. The ability to create stitched images quickly and easily is important for all quality control environments. The left image consists of nine images.
