This component is a ball-bearing linear guide, which provides precise linear guidance along the Y-axis in a die bonder. In Besi die bonders (such as the Esec 2100 series), the pick-and-place system relies on high-precision linear guides to facilitate the high-speed reciprocating motion of the bonding head between the pick-up and placement positions. The rigidity and operational precision of the guide directly influence placement accuracy (for instance, the Esec 2100 hS features a standard accuracy of 20μm @ 3σ). Wear or increased clearance in the guide can lead to Y-axis positioning deviations, which in turn negatively affect the die-bonding yield. As part of routine maintenance, the guide must be cleaned regularly and lubricated with a specialized lubricant to minimize wear.
