What is a Bidirectional Switch? A bidirectional switch is an electronic component that allows current to flow in both directions when the switch is closed. Unlike a traditional unidirectional switch, which only allows current to flow in one direction, a bidirectional switch enables the flow of current in either direction depending on the polarity of the applied voltage. Key Features of Bidirectional Switches Current Flow: Bidirectional switches allow current to flow in both directions when Read more…

What is SMT Assembly? SMT (Surface Mount Technology) assembly is a method for producing electronic circuits in which the components are mounted directly onto the surface of printed circuit boards (PCBs). This technology has largely replaced the through-hole technology construction method of fitting components with wire leads into holes in the circuit board. SMT allows for the production of smaller, faster, and cheaper electronic devices. The SMT assembly process involves several steps: Solder Paste Printing: Read more…
