1. Check printing accuracy. 2. Check placement accuracy. 3. Your components should be kept in a good environment to prevent oxidation of terminations. 4. Pads pattern should be designed according to standards.

If 1.2. are okay, you should suspect 3.:oxidation. Conveyor speed of oven may not be a big fact, for the part is very small.

Good luck.
