An optocoupler, also known as an optoisolator or photocoupler, is an electronic device made up of an LED emitter combined with a photodetector, separated from each other in proximity. There are many types of photodetectors, most of which are variations on a photodiode or phototransistor.

Lower level testing (subsystem, equipment, component) is frequently avoided, and the quality of these, given for granted. While this testing plan may be suitable for demonstration missions, we believe that shortly commercial missions will need a deeper quality assessment.

Assembly of initial prototypes and small quantities into cavity packages can be provided in Europe, this is only cost-effective for 10 units.  Users with low to medium applications such as space, medical, industrial, and aerospace struggle to find assembly at reasonable costs. They are never likely to reach volumes that are attractive to high-volume OSATs.  Small batches requiring numerous set-ups and a stop-start of production lines make factories very inefficient in an age where efficiency is critical to their survival and cost structure.

This standard describes the differences and the minimum testing requirements necessary to each of these three classes for evaluation, screening, and lot acceptance. The following test sequence shows the evaluation test sequence for class 1 components, this sequence is the same in the three classes described in the standard with different severity and test conditions to each class.
