"As a department, we're responsible for component analysis; looking at alternative or new components that we test for robustness and conformity to data sheet specifications," explains Component Engineering Manager
"We saw the KEYENCE VHX-970F high-accuracy digital microscope and knew it would meet our requirements," says Massey. "Also, staying with
As an option, the company invested in a digitally controlled Z-axis for the VHX-970F that it did not have previously.
"It allows us to automate the focus, assisting ease of use," he says. "Supported by the microscope's impressive depth of field we can also use the digitally controlled Z-axis to take multiple images from different height perceptions if we have a particularly awkward or complex component to inspect."
The KEYENCE VHX-970F has three main roles on site at TDK-Lambda
"We also use it for inspecting wire crimps, making sure we have the correct compression and right fill in the crimp barrel," explains Massey. "Using the VHX-970F provides exceptionally reliable results because of the ultra-high resolution it can provide, while its ultrafast frame rate is much quicker and easier than performing a physical pull test on the crimp."
Thirdly, the VHX-970F checks factors such as solder fill on the company's PCDAs (power control and distribution assemblies).
"The microscope is in daily operation and we find it very easy to use," says Massey. "Once you learn how to drive it and know where the buttons are, everything becomes straightforward. We're also beginning to get familiar with some of its advanced functions, such as HDR [
Leveraging 16-bit intensity range through RGB data from each pixel, the HDR imaging function captures multiple images at varying shutter speeds to obtain an image with high colour gradation.
"We're still experimenting with HDR, but it's just one of many possibilities with this advanced microscope," concludes Massey.
