When customers need a high-performance connector for their critical interconnect applications, Mill-Max precision-machined pin technology is the answer. Mill-Max Interconnects offer multiple advantages over their stamped-and-formed counterparts:
- Receptacle shells have seamless construction, preventing solder contamination from entering the electrical contact area during wave or reflow soldering operations.
- Countersinking at the top of machined pins promotes alignment, making assembly more productive.
- Machined sockets are made with brass alloy 360 ½ hard, an alloy known for its strength, conductive, and thermal properties.
- Press-fit assembled inside each receptacle shell is a highly reliable, four-finger beryllium copper contact clip, which scores the mating device lead, forming a gas-tight electrical and mechanical connection. For high-temperature applications of more than 150°C, an alternative beryllium nickel alloy is available.
- Multi-finger contact clips are superior to wiping connector blades because they provide multiple points of contact to the mating pin, providing better power and force distribution.
- Two-piece receptacle construction (shell and contact clip) allows for cost-efficient plating combinations. Receptacle shells can be plated with tin for solderability. Contact clips can be gold-plated for optimum conductivity.
- Socket insulators are made from high-temperature thermoplastics suitable for reflow soldering temperatures.
- Non-standard footprint pattern insulators can be easily created and configured using in-house PCB routers to machine FR-4 epoxy or G-30 polyimide for applications greater than 150°C.

Are you looking for ways of connecting two parallel conductive surfaces inside an electronic device or instrument? See how Mill-Max Spring Contacts can be used to accommodate uneven, non-parallel or blind mate connections.
Are you considering mechanically fastening pin terminals to a circuit board? Swage assembly is commonly used with solder terminals and printed circuit pins where one end of the terminal is flared out (riveted) securing it to the PCB.
Are you faced with limited space requirements and need to reduce the height of your board connector? Review how socket carriers will reduce your connector height through the elimination of the insulator.
