Not sure how these boards will be categorized . Looks like some telco some backplane,appreciate the help. BearScrapper

A backplane don’t trim
B backplane don’t trim
C backplane trim
D high telco
E backplane don’t trim
F low gold finger card
G if not gold peripheral. If gold gfc
H gold finger card

Explain low gold finger card. 3 letter words again throwing me off, thanks

Here we have a board that just barely would qualify as any sort of gold finger card. It’s way outside of IEEE and EESA size constraints.
In other words mounting this perpendicular to a mother board in a vertical tower is a terrible idea. As such, and only because the new class exists, I’ll say low grade gold finger card.
In the past I’d have placed it in peripheral (do NOT trim) class.

I noticed that board A has two connectors on the back side that I think you may have missed. I would think that having those extra connectors would make that board able to have the fingers trimmed off without hurting the value.

I personally wouldn’t risk it on this one.
Personally. If it were a pass through board rather than a riser I would have tossed it in peripheral. Essentially the same thing as cutting the fingers off here design wise.

OK. I just thought you might have missed the two connectors on the backside of the board. Thanks for the reply.

It’s a close one.
But I approach from a true backplane and work my way out into the rest of what boardsort buys as one. This is about the end of the line.
On my own moving through random unsorted boards if I came across that and it didn’t have the edge connector I would have just tossed it in peripheral with no second thought.
For that reason I say cutting it off is a risk here.
