In this day and age, technology changes fast. Electronics, in particular, has seen constant changes and has really shaped up the way we interact with a lot of devices today. As the PCB is shrinking every day, so are the electronic components attached on to it. And while that leaves us with efficient and aesthetic finished devices, it also creates a lot of unprecedented challenges for the design engineers that work on any ground breaking product.
One of the biggest challenges has been PCB inspection. As SMT components have become smaller and more complex, PCB inspection has become extremely crucial down to the microscopic level. So, should we keep on using the traditional cameras that have been at our disposal or is there a need for a new technology to come in?
Turns out, the engineering community believes that while traditional eyepieceless cameras were efficient enough to deal with PCB inspection a few years ago, the challenges today require for specialised PCB inspection cameras to come in. Stereo microscopes were first introduced to check for errors within a device down to the PCB level which were later replaced with cameras without a scope where the camera’s display was projected on to a screen.
However, A certain amount of skill and training was still required with the ‘eyepieceless’ stereo microscope, still difficult to look at the magnified image and at the soldering iron to see were you are working, the ‘eyepieceless’ stereo microscope obscuring the view of the work piece from the operators view.
With PCB inspection cameras, there isn’t a need any more to employ highly skilled operators, and the person handling the camera can sit with a good posture without any equipment obscuring the operator’s view. And engineers believe that is going to change a lot of things. One of them simply being higher efficiency of the product while minimum input from the operator.
While, people still believe that we’ve come a full circle in that the people in assembly lines are testing the PCBs with their naked eyes, using a PCB inspection can help in enlarging on a particular problematic part and saving the same image to share with engineers to work on. With a great ergonomic inspection, large working distance, large depth of focus, and a magnified field of view, PCB inspection microscopes offer much better results compared to standard stereo microscopes or the naked human eye.
While, a lot of companies today are dealing in PCB inspection microscopes, we are highlighting the KPH 03 HDMI MICROSCOPE here, simply because we believe that it offers better value for money while checking all the boxes that an ideal PCB inspection microscope should.
