Pre-soldered Pin
Pre-soldered pins are leads or pins with a precise amount of solder pre-melted on the tip, simplifying solder placement in assembly. During packaging, simply insert the pin into the corresponding hole of the package and braze – achieving both electrical connection and mechanical fixation in one step.
