As Principal Engineer for a large connector manufacturer, each day I am challenged by EEs and MEs to help bridge their leading edge technology from one module to another. I remember years ago, when the pin grid array went obsolete to the emerging QFP quad-flat pack, people said "screw machine was a goner".
Compounded by the fact, that the entire electronics industry was migrating to high density, high-speed SMT assembly methods, that surely was to become the final nail. But somehow...screw machine technology evolved and survived. Even with advances in BGA and LGA packaging...we're still standing LOL... In fact, of my 35 years, 25 in the world of screw machine, the applications of screw machine technology continue to grow at an exponential rate. It's not by accident that military, medical, aerospace, industrial, automation, robotics, telecommunication and every other industry involved in the design of the most leading edge technology, relies on screw machine interconnects for their most critical, failure-is-not-an-option applications.

This technology traces back to Swiss pride & precision watch making many moons ago. A few thousand years from now, this discussion will continue. This proven technology is not ready to leave anytime soon.

Nope, not yet - Regards, Marty
Here is a brief description of each image: From top row, left to right:
Top Row L to R
1. Swage Rivet Pin for wire attachment
2. Screw machine low profile receptacles can be packaged on tape and reel
3. BeCu contact clips integrated into shells for multiple points of electrical contact
4 & 5. Screw machine pins with polygon features (flats) for SMT assembly
Middle Row L to R
6. Horizontal SMT 26AWG wire capture devices
7. Cross-cutting features to promote solder wicking.
8. V-Groove features to promote solder wicking
9. Eye-of-Needle Compliant Tail technology for solderless attachment to PCBs hard to solder.
10. Polygon cutting (hexagon) for solderless press-fit in multi-layer PCBs
Bottom Row L to R
11. Socket Receptacle Technology using BeCu multi-finger contact clips.
12. Spring Loaded Contacts (SLC) used everywhere in modular design.
13. Lead bending to create SMT connectors
14. Channeled grooves for solder wicking of power pins, high conductivity alloys
15. A press-fit barb, the simplest, most reliable feature for pin retention in thermoplastics
and FR-4, but not intended for insertion into PTHs. (ask me why)
