Peter,

I don't believe there is anything in IPC-A-610 specific to this, but there are requirements in J-STD-001. See paragraph 4.18.3 "Partially Visible or Hidden Solder Connections"

Subject: EXTERNAL: [TN] Vertical fill

Hi everyone,

We have a conflict between inspectors.  We have a through hole header where the destination side solder joints are partially hidden.
This is an IPC-A-610 Class 2 assembly and we are wondering what are the requirements for vertical fill and wetting on the destination side when you can't see them?

Thanks
Peter
