Mastering Dual-Camera Vision Calibration on the AP CHM-T48VB
The AP CHM-T48VB desktop pick-and-place machine relies on its dual-camera optical system to bridge the gap between mechanical motion and sub-millimeter component placement. While closed-loop stepper motors provide steady positioning, mechanical tolerances, thermal expansion, and component tape variances make purely coordinate-based placement unreliable for 0402 passives and fine-pitch ICs. Proper calibration of both the top-facing […]
