Why onTAP
Test software, embedded control, custom PCB, instrument control and fixtures can be developed and integrated under one architecture.
Systems are defined around DUT interfaces, signal paths, coverage and production operation instead of a single device template.
Beyond test function, we consider operation, maintainability, changeover, traceability and cycle-time factors.
Supports local communication, custom development, product selection and on-site engineering collaboration without unverified 24/7 claims.
