content: I've only seen these few times in past.There is a type of socket that get directly soldered to PCB with its top almost flush to top of the board. It's just a metal part of socket and no plastic shroud of any kind. I believe HP used some of these for mounting 2N3055 type transistors to a heat-sink/PCB sandwich.What are these pins called?I can't just take apart IC socket as pins are too large. I'm making a test fixture for OCXO for testing. As it is for testing, I don't want to solder pins. I figured these socket will be ideal for mounting and dismounting for testing purposes.If anyone can give me a name for this stuff, I'd appreciate it. If there is a source, I'd doubly appreciate it.

content: Quote from: FenTiger on November 18, 2020, 06:24:36 pmWe usually call them PCB Sockets, Turned Sockets, Two-Piece Sockets - basically we don't have a great stand-out name for them, sorry!We do a range of them, depending on the size of your mating pin will depend which you choose. Some have knurling on the outer diameter - this is not to replace soldering, this is just giving additional mechanical retention, soldering is still required for a good electrical joint.You can browse our current selection athttps://www.harwin.com/connectors-hardware/durable-industrial-connectors/pcb-sockets/, and you can read more about the range athttps://www.harwin.com/pcb-sockets/. If you click through to a product page, you can see stock levels at our authorised distributors.Hope that helps!

content: Thanks! I'm surprised to receive a reply from a company rep.Unfortunately, none of them will work for my application. OCXO typically have lead thickness between 0.8 and 1.2mm. Only product that fit these sizes are open design.

content: I usually refer to them as machined collet sockets or machined collet pins. Tektronix used Berg Miniserts; PDF attached below.I buy SIP sockets and cut them apart to install the pins manually as shown below.Well, it would be shown below for forum is returning error "Your attachment has failed security checks and cannot be uploaded.

content: You mean the type commonly used for Arduinos? (except they are machined?) I've tried that.... pins are too big, or holes are too small.I just remembered I have some MIL spec connectors with similar pins. If I can find them, I'm going to try that. I have no use for them otherwise.
