Meaning
Automated placement systems drive conductive pins into printed circuit boards at velocities that support high volume production lines. Through high speed pin insertion, a manufacturer can populate connectors and headers without the thermal stress of manual soldering. The process relies on precise force control to prevent board fracturing.
Mechanical Action
A hardened steel tool strikes the top of the pin to drive it through the plated hole. Interference between the pin and the hole wall creates a gas tight connection.
Press Force
Monitoring systems track the pressure applied during each stroke to ensure it falls within a specific range. A force that is too low indicates a loose fit, while a force that is too high suggests potential board damage. These values are recorded for every pin to provide a complete history of the assembly.
The machine stops instantly if a limit is exceeded.
Placement Accuracy
Robotic arms must align the tool with the center of the hole to within a few microns. Vibration from the high speed movement is dampened by a heavy granite or cast iron base. Sensors detect the edge of the board to establish a local coordinate system before the first pin is placed.
