Subject: [TN] PTH hole fill for U-shape ground pin
Technet,
I have one minor issue with a ground pin solder hole fill. This ground
pin is flat and has U shape at one end and the U-shape end is inserted
into two PCB holes that are connected together. These two pins (U-shape
with 0.1" spacing ) are mechanically and electrically connected.
Typically, we have ~80% hole-fill on one of U-shape pins and the other
U-shape pin has ~20% hole-fill.
Are these hole-pins acceptable as per IPC Class 2 requirement? I
couldn't find this specific standard in IPC 610D. If I remember right,
an older 610 has this specification. I know IPC 610D section 7.5.5.1
states min 50% hole fill is acceptable for one ground pin hole for
Class 2.
thank you
Matthew
