Electronic components are used every day, what do they look like inside? Want to see it? Today, we will take a look at the unfamiliar internal structure of electronic components. The following is a cross-sectional photo of these components after cutting and grinding:
01 Surface Mount Capacitor
02 Film capacitor
03 Electrolytic capacitor
04 Ceramic capacitor
05 Tantalum capacitor
06 Metal film resistor
07 Light powder resistance
08 Color ring inductance
09 LED
010 diode
011 Triode
012 Button
013 Sliding single pole double throw switch
014 Double row of pins
015 Reed Switch Relay
016 DB9 connector
017 Electron tube
018 Network transformer
019 Button Battery
020 Electret MIC
021 Seven-segment digital tube
022 Optocoupler
023 Headphone connector
024 BGAEncapsulation
To make the cross-section of the above components, generally need to go through the following steps:
[1] Use epoxy resin to vacuum soak the components for fixing;
[2] Use grinding or cutting to remove the surface layer of the components;
[3] Polish the remaining part to show a clear cross-sectional image;
[4] Take photos and observe under a magnifying glass or microscope.
