I have a question about hot to solve a trouble of production. One PCB need a optical isolation, I have a LED diode and a photo diode, they are through hole. To solve this i think that if exist this components in SMT will solve my problem.
What about using an optoisolator? It has the LED and phototransistor in a common package, with guaranteed high voltage isolation between them. They are available in SMT as well as TH
The first is the generation of pulse and the second is the return to the microcontroller to identify if the pulse is complete or not, to generate another.
This PCB is isolated to two optical components, but in the manufacturing of many products the production process is slow. Because the two components must be bent 90 º to hand.
