You'd figure push-in force is the same order of magnitude as push-out force. Data sheet lists 4 lbs minimum push-out, so let's say around a max of 8 lbs push-in. I agree that it probably is not difficult to come up with something to do that. The drawings appear to show a construct which is significantly more robust against buckling than common stamped press-fit pins. Need pretty tough fingernails, but in lieu of those, they make nice little arbor presses you could set up with a dowel pin to press something like that in with a fair degree of control.

Subject: [TN] Holtite socket receptacle insertion



Hi All,



We just had a customer revise an assembly with us and have chosen to use some Holtite sockets for a through-hole photo diode on the assembly.

The board is really small, about 1" square and .062" thick. It also has double sided SMT on it, so there's not much room around the holes. I say that because from what I remember when I last used these sockets, is that we used a hand tool that was more like a spring loaded center punch (it's on page 6 in the PDF above) that has different tips that you changed out depending on what part number socket you were inserting, and it took a surprising amount of force to seat these sockets. Of course the tool is close to $300, and I'm thinking we'll need a press fit fixture to support the PCB when we install them because the board is only .062" thick. But our customer says they built some proto assemblies with these sockets and was able to press them in with their finger nail, does that sound right? I'm thinking that the holes were probably oversized and they aren't getting the kind of connection between the socket and barrel that they need to be getting to have any sort of reliability.



Is my memory getting that fuzzy?



Steve
