LeoBodnar: Heads up about a potential quality control issue on your SMA pulse generators
<azonenberg>
I got one a week or two ago and gaged the SMA and the center female contact was sticking out 0.0015" past the reference plane
<azonenberg>
I suspect it was overtightened during assembly
<LeoBodnar>
ooh, cheers, I will keep an eye on this
<LeoBodnar>
is it OK now?
<azonenberg>
Or maybe there was too much solder on the contact
<LeoBodnar>
i.e. can you deal with it?
<azonenberg>
The connector i think is damaged beyond repair. I believe it's Amphenol SV Microwave SF2921-61356 or a very similar connector
<LeoBodnar>
it should be a dry contact but I have found that some connectors don't make good contact
<azonenberg>
I ordered a replacement
<LeoBodnar>
yep it's SV
<azonenberg>
(Which cost me $16.21 at digikey plus tax and shipping)
<LeoBodnar>
I can refund you or send a replacement
<azonenberg>
So i'm going to gage that connector new out of the box, then install it, very carefully and paying attention to contact position as i tighten it
<azonenberg>
The cost isnt that big a deal but i wanted you to know in case this was a production issue affecting a whole batch
<azonenberg>
Since having the contact stick out too far risks damaging the male contact of hardware it's mated to
<LeoBodnar>
got you, thanks for the heads up
<azonenberg>
I'm in the process of acquiring a 16 GHz scope and don't want to be messing up any of the rather pricey cables and fittings I'm using it with so I'm starting to gage all of my cables and connectors
<azonenberg>
And this is one of the many that failed
<LeoBodnar>
I suggest wicking all the solder from the pad then
<LeoBodnar>
the worst that can happen then is intermittent contact
<azonenberg>
Yeah I'll probably do that
<azonenberg>
Maybe your manufacturing shop put too much solder on the
<azonenberg>
pad
<LeoBodnar>
I thought you wanted to remove the connector altogether for direct testing of your probes?
<LeoBodnar>
I'll keep an eye on this
<azonenberg>
No, I actually have a fixture now that mates with the SMA and has a signal and ground point
<azonenberg>
with characterized electrical length etc
