The coding sensor measures light ...... the problem is making the black bits black enough and in the right places .... and reflected light at all will make the sensor register 'white'. There is no need at all to bother with the white bits.
In fact I've often thought it would be more sensible to paint the whole area black and just add a few white dots in the right area ...... the sensor is very sensitive.
If it doesn't work or you get the wrong result it usually means the black areas aren't big enough. It may take a bit of trial and error. I laser printed a master layout plan with the flange holes marked on it on Overhead Transparency Film ** so I could align with the flange and check I had things in the right place, but there are plenty of other ways of doing it.
There have been some issues with replacement flanges not being the right thickness (not an issue with the SL) or an uneven thickness resulting in part of the sensor image being OOF. Some have also been either sloppy fits when the lens is mounted .... or far too tight. You get what you pay for. If they work, fine, but I would check everything fairly thoroughly with some test shots before congratulating yourself on having saved some cash .....
