I have added three more close ups of the tip socket in the Photos folder here at TekScopes named "Tektronix P6202 FET voltage probe tip problem "
Someone asked me in an email if I could put a link. I wish I knew how. I don't think I can link to a pic that I've posted.
Go to the picture you've posted, open it in your browser. In the
address field of the browser window (which changes to where you are),
select and highlight the complete address.
Go back to your email and paste that in.
That's one way to do it.
I am new again to Tekscopes. I don't know how. But you will find almost 20 good pics of a P6202 Fet probe that will hopefully help me or someone else in future deal with a damaged tip socket.
The socket seems to have a U tab that straddles the end of the PCB. It is probably hard soldered in a jig. Likely the socket is closed at the bottom to prevent wicking.
These sockets are indeed closed at the bottom. They're meant to be
put into a PC board and soldered in to lower the profile of whatever
chip (or part) is inserted into them.
The small teflon? washer is slightly loose on the body of the socket but doesn't come off. I can see what I think is the FET and a couple of surface mount resistors? one of which is adjacent to the solder pad for the tip socket.
The teflon washer is likely meant to keep the probe tip from grounding
out against the outer probe body.
Pics show an object, probably a broken off piece of wire, round in a square hole. Too small and too deep to grab.
I don't know how to deal with this.
One would be to replace the socket.
Another would be to remove the socket, go to a room without much in
it, grasp the socket firmly (but gently) with pliers, and then bang
the pliers sharply against a block of wood. If the obstruction goes
away, you're lucky.
A question is to ask if you are sure that the socket is obstructed. It
has to have a set of contacts in it. Take a sewing needle or pin of
the right diameter (I measured 0.030 on the tip of my P6202), and see
if it is obstructed. The needle should bottom out gently.
if a simulated probe tip fits in, there may not be an obstruction. I'm
rather puzzled how something could break inside the socket. I've seen
many broken tips, but they all die at the junction of the external tip
and the replaceable body.
If you can't clear it out, and you're willing to take a chance, I have
a few sockets that a probe tip will slide into. You'd have to be
willing to remove the socket and replace it, though.
