I would still verify what you are receiving and your current bath setup. This only because you are experiencing problems. Simple check, takes 2 minutes. I have seen this before, but it took 8 hours to delam at with pre-mix. This was 5 or 6 years

We discussed about applying 2 dots of glue on either sides of the LED body, but have yet to try it out. Other discussions include conductive adhesive, using fixturing with weight, different stencil aperature design, hand soldering.

If you are talking about a chip capacitor, then I think it's 50% (of component width) side to side for class 1 and 2. And 25% for class 3. There is no end overhang permitted for all 3 classes.
