Well, if you have a customer who insists on coverage under there, you can manually dispense some with a syringe.  It isn't a quick process though...

Subject: [TN] Coating under connectors

Dear Technos,

 

Per IPC-HDBK-830, all solder joints and exposed leads should be coated. How does this apply to SMT connectors like this http://ipc-technet.groupsite.com/gallery/22102 ?

 

In this case, the connector is very low profile, all the joints plus many vias are hidden under the body and the coating will probably not wick over the whole area, so there will be many exposed metal features not coated.

 

I suppose the -830 requirement still stands and the situation under the connector is a defect?

 

Thanks,
