I. Product Overview

Developed by ABONA (ABN) based on industrial automated production line architecture, the P-A Automatic Test System integrates fully automatic loading & unloading modules, high-precision positioning stages, multi-channel test modules, high-frequency RF test units, intelligent measurement & control software, and a data traceability system. It accommodates full-size P-A ranging from 50×50mm to 610×500mm and supports synchronous single/double-sided testing.

The system conducts a comprehensive array of tests including DC parameters (open/short circuit, resistance, capacitance, inductance), analog signal characteristics, high-frequency RF S-parameters (≤110GHz), and functional continuity testing. It achieves mΩ-level test precision for resistance and pF-level precision for capacitance. A single unit can test hundreds to thousands of P-A boards per hour. In addition, it seamlessly interfaces with factory MES systems to enable real-time test data collection, automatic sorting of defective products, and full-process data traceability.

Classified by testing principles and applicable scenarios, the system falls into four categories: ICT Automatic Test System (In-Circuit Test), FCT Functional Test System (Finished Product Function Verification), High-Frequency RF Automatic Test System (Specialized for high-speed/high-frequency P-A), and FPC Flexible Circuit Automatic Test System (for flexible board bending and dynamic testing). It fundamentally addresses core industry pain points in mass P-A production, namely low testing efficiency, significant manual errors, lack of data traceability, and difficulties in testing high-end P-A. Balancing mass-production throughput and testing accuracy, it meets mass inspection requirements for P-A used in consumer electronics, automotive electronics, communication equipment, industrial control, medical devices and other sectors.
