I've got much difficulties to find the footprint for the components I have in hand:
They don't have name (I buy them at somewhere similar to flea markets). Therefore, their proper footprints are unknown nor I don't know where to find such information. So far, I've been wondering if every component (such as resistor, cap, connector, header..) they all have standard footprints? where to find such information?
For the libraries available in CAD tools like eagle, proteus, orcad, they don't have the visualization (photo...) of the component so that I can guarantee the chosen footprint is suitable with the real one
For such reasons, I would like to know if there is an online or offline component library and browser which has:
1 photos of each component. This is meaningful since it may help to quickly verify if this component is the one the designer is having at hand or visually remember
corresponding footprint with some brief descriptions about pad size, distance between pads. This supports specific measurement information for the given photo
I am still at learning level in electronic design and have found EE SE is a great learning resource. Please pardon me if my questions does not make sense. In that case, your response would also help me to justify my understanding.
