Gold Plating Brass Solder Cup Terminal Pins 12.75mm Precision Machined Solder Cup Terminals for PCB Connectors

JRKCONN manufactures high-precision solder cup terminals for wire-to-board and wire-to-pin connections. Each terminal is produced through controlled CNC turning to maintain consistent outside diameters, cup geometry, cup depth, and soldering areas. The result is a reliable connection solution for applications where electrical continuity, mechanical strength, and assembly consistency matter.

Our machined pin solder cup terminals are available in high-conductivity brass and other copper alloys, selected according to the required current rating, wire size, and operating environment. Precision turning helps maintain a stable geometry and consistent wall thickness, making wire insertion, soldering, and final assembly easier and more repeatable.

Because the solder cup design does not require a dedicated crimping tool, it is well suited to hand soldering, semi-automatic assembly, prototypes, and custom production. With the right material, plating, and design, these terminals can be used in aerospace electronics, medical equipment, industrial controls, test and measurement instruments, and other high-reliability electronic assemblies.

JRKCONN solder cup terminals are suitable for:

• Aerospace electronics and avionics
• Medical instruments and diagnostic equipment
• Industrial automation and control systems
• Test and measurement equipment
• Communication and data transmission modules
• Power and control cable assemblies
• High-reliability electronic assemblies
• Custom wire-to-board connectors
• Wire-to-pin connectors
• Compact precision instruments
