A Low-Cost Modular PCB Assembly for Functional and In-Circuit Testing

This dataset accompanies the paper "A Low-Cost Modular PCB Assembly for Functional and In-Circuit Testing", the design and implementation of a modular, low-cost printed circuit board (PCB) assembly to perform in-circuit testing (ICT) and functional testing (FCT) of electronic assemblies during prototyping and small-scale production. The hardware integrates multi-parameter measurement capabilities—including multiple testing functions, programmable voltage stimuli, relay-based switching matrices, voltage/current/resistance/capacitance measurements, and functional signal testing, all coordinated by an embedded MCU on a modular PCB assembly.

Unlike conventional modular ICT/FCT platforms, the system emphasizes architectural integration, reduced structural complexity, and ease of deployment in resource-constrained environments, including small- and medium-sized enterprises (SMEs) and in-house prototyping laboratories. The design rationale, hardware architecture, and implementation are described in detail, along with representative experimental validations that demonstrate functional and practical measurement ranges.
