Products Description
Robust Board-Level Fastening and Current Transfer
Standard PCB pads are not designed to handle the mechanical stress of a screw-secured connection. When your assembly needs to hold a screw, ring terminal, or small metal conductor directly on the board, our Custom PCB Solder Lug Terminal With Threaded Hole replaces a simple pad with a rugged, solderable anchor point. It functions as a board-integrated threaded contact, reinforcing the assembly with a dependable fastening area and a stable, low-resistance current path. By combining soldered mounting feet with an accurately tapped hole, this component merges strong mechanical fixation with efficient electrical performance in one compact piece.
Material Selection and Surface Finishes
These terminals are primarily stamped from brass or copper alloy strip, materials chosen for their excellent conductivity and formability. For designs demanding extra spring resilience or fatigue resistance, phosphor bronze can be specified. Custom alloys are also available upon request to match unique performance conditions.
The final surface treatment is selected based on the joining method and operating environment. A tin-plated finish is the standard choice when the terminal will be reflowed or wave-soldered onto the PCB, ensuring superior solder wetting and long-term joint integrity. For assemblies that require higher corrosion protection or do not involve soldering, nickel plating or other specialized finishes can be applied.
Tailored to Your PCB Layout
Every terminal is configured around the customer's board geometry. Because a minor revision in PCB layout often demands a different terminal outline, we strongly recommend drawing-based production to guarantee a perfect fit. The critical dimensions that must be defined include:
Mounting foot spacing (pitch)
Exact threaded hole position
Board hole diameter compatibility
Overall terminal height
Contact surface area
Required current-carrying capacity
Additional customizable features cover material thickness, plating type, contact width, and precise hole pattern matching. Whether you need a common M3 or M4 thread or a fully custom thread size, the terminal geometry adapts to your design.
How the Terminal Is Made
The manufacturing sequence involves precision blanking, multi-stage bending, hole punching, thread tapping, and final surface plating. This progressive stamping and forming approach consistently delivers accurately positioned feet, clean threads, and a uniform finish, ensuring that each piece solders smoothly and holds torque reliably.
Common Applications
These threaded PCB solder lugs are widely used in power modules, control boards, battery chargers, switching power supplies, and general industrial electrical equipment. They are also ideal for power board interconnects, circuit board assembly, high-current electrical contacts, and any screw-fixed wiring point where a board needs a durable, bolted metal connection.
