One way we handle this situation is to produce a wave pallet that presents the pcb at an angle to the wave to stagger the leads of the connector.

Do you glue SMT parts on the bottom? If so, use your SMT glue to prevent the short. Just cut a new stencil with 0.020" wide apertures between the pads of the connector (bottom side). We do it all the time.

Hello, I think the problem can be: 1.�- some humidity in the adhesive, 2.�- some bubble of air in the adhesive when you cured the adhesive some humidity will go evaporate and when you make the soldering the same soldering will make a bridge between t

Dear all friend, I found problem of soldering bridging between SMT Chip terminal & Glue , but under the chip body. My process was double side SMT assembly with bottom side adhesive & heat curing, then wave soldering with water soluble flux (OS type)

Hi MSK, Stencil thickness: 5mils with laser cut Smallest pitch: 20mils Underscreen cleaning frequency: 10 bds per cleaning Note: We have decreased the cleaning frequency from 10 boards to 3 bds to reduce solder bridging after printing Regards,

What is stencil thickness & what is the pitch of your component.What is your cleaning processor for stencil.
