Hi,
As you know, a flyback SMPS transformer must be wound with dotted ends at the same end of the bobbin for every coil. This is for EMC reasons.
But if you get the transformer manufactured outside, how do you best check/ensure that they did actually put dotted ends at same end?
You can check which pin is "dot" and which is "no dot"...but you cant see "inside"
