What protects the LED from over supplying of voltage?
Several circuit protection technologies – including metal-oxide varistors (MOVs), TVS diodes, LED protectors, and fuses – are needed to provide overvoltage, overcurrent, and high-temperature circuit protection for commercial LED lighting systems.To protect LEDs from too much current, you can use a current-limiting resistor in series with the LED.

SMD Power Supply Filter Design Tips
What is the purpose of using a filter in a circuit?A filter is a circuit capable of passing certain frequencies while attenuating (to reduce or block) other frequencies. Thus, a filter can extract important frequencies from signals that also contain undesirable or irrelevant frequencies. In the field of electronics, there are many practical applications for […]

General Knowledge of PCB OSP Surface Finish
Copper plays a conductive role in printed circuit boards (PCBs). As a reactive chemical, copper is prone to oxidation when exposed to atmospheric humidity, thereafter leading to problems that may occur in high-temperature soldering, which is detrimental to the reliability of the components mounted on the PCB and the final product.
Why Fiducial Marker Placements on PCBs so Necessary?
A fiducial marker or fiducial is an object placed in the field of view of an imaging system that appears in the image produced, for use as a point of reference or a measure. It may be either something
