Polarized components require special attention throughout the PCBA (Printed Circuit Board Assembly) processing, as incorrect orientation of polarized components can lead to mass failures and the complete failure of the PCBA board. Therefore, it is crucial for engineering and production personnel to understand SMT polarized components. 1. Definition of Polarity Polarity refers to the positive … Read more
During the production process of PCBA soldering, operational errors can easily lead to defects such as: cold solder joints, short circuits, component lifting, missing components, solder balls, component misalignment, excessive solder, incorrect components, cold soldering, reverse soldering, white/reverse side issues, misalignment, component damage, insufficient solder, excessive solder, solder sticking to gold fingers, and glue overflow. … Read more
I have seen cases online where Arduino is used to create a simple electromagnetic radiation tester, typically using several LEDs to display the intensity of electromagnetic radiation. The micro:bit comes with a built-in LED matrix, so I thought it would be more intuitive to migrate this small experiment and use the matrix to display radiation … Read more
