We currently use and have used Aim W/S 483 for the past ten years. We have had great support from AIM. Paste Characteristics, wetting, slump, washing is all outstanding. Great activity, works well with NiPd and other lead frames.

Baking of the component helps it depends on the type of contamination and how much contamination. It sounds like your purchasing is buying from brokers.

To get out of a delivery pinch, I had to pre-tim some connectors because of contaminated leads. Make sure your selective wave speed and XYZ travel are close. Try doing a dry run across the board to preheat the PTH and then go back and solder them.

We side with your operator. Poor pad design is the largest contributor to component shift. If you posted pictures, we might have a livelier discussion about alternate explanations.
