What problem does it solve? Engineers maintaining the HT9045 IC Test Handler struggle to trace the InArm (Input Arm) pick-and-place logic scattered across multiple C++ state machine files with numeric case values. This Skill maps every state, dispatch rule, and error path so you can diagnose jams, pick failures, and flow issues without reading thousands of lines of legacy Borland C++ code. ## Core Features & Use Cases - State Machine Reference: Complete case-value tables for DoInArm, DoInArm_9045 dispatch, Pick from Loader, Place/Pick HotPlate, and Place to Shuttle flows. - Error Handling Guide: Documents Retry/Skip/Home/Tray End/Clean Out paths, IC fall-down detection, sticky IC checks, and Shuttle floating verification. - Picker Configuration Dispatch: Full iInArmType table mapping 25+ sucker geometry variants (1x1 through 2x8) to their handler functions. - Use Case: When a technician reports the InArm stuck at iArmTask case 1100, load this Skill to immediately identify it as the Place-to-HotPlate state and follow the documented sub-flow to find the failing step. ## Quick Start Ask the AI to explain what the HT9045 InArm is doing at a specific iArmTask case value or why a Loader pick error occurred.
