I am looking to discuss 0402 issues, specifically tombstoning/unsoldered. Any recommendations on pad size/spacing, stencil design etc would be helpful. Placement and reflow profile look good.

We are trying to solder a Surface mount relay having lead free finish on the leads. The leads are not getting soldered down during the reflow. The leads also look oxidized (failed our solderability test) but we don't have an option but to use these r
