There was an optical wrinkle in the plastic that was affecting pickup rig= ht at the pin diode location. But the Chinese kept saying it had no problem with mold. So customer asked me to drop in and look myself. Of course the mold was repaired and make perfect looking plastic to the n= aked eye. In USA you could see a slight change in index of refraction. But not in China. So I had to show them with a webcam. They had a gouge in the mold but repaired it but with slightly different = metal. Not sure why, but it did. They had no clue and did not want to admit they did not know how to fix. Sometime I hate "saving face" If I get one bad assembly in one million it is a lot from Thailand. Give them a kit of parts, drawings and sample, then I just walk away. Sometimes I make a test fixture.
