PCBA Copy from Physical Board is a foundational service that replicates a PCBA directly from a physical, tangible circuit board—no digital design files required. This service is critical for businesses that only possess legacy PCBs (e.g., from discontinued equipment) or lack access to original design data, enabling them to reproduce functional copies for maintenance, production scaling, or obsolete part replacement.

The workflow starts with physical board preparation: the original PCBA is cleaned to remove dust, solder flux, or debris that could obscure details. Engineers then document every physical attribute using specialized tools: high-resolution optical scanners (capturing top/bottom layers, silkscreen, and component placement), X-ray machines (mapping internal layers for multi-layer PCBs and hidden connections like BGA solder balls), and calipers/CMMs (measuring PCB dimensions and component positions). Component identification follows—recording part numbers, values, and package types via visual inspection or component testers (for unmarked parts like resistors/capacitors).

Next, reverse engineering converts physical data to digital: PCB design software (e.g., Altium Designer) recreates gerber files by tracing conductive paths, replicating via sizes, and matching layer stack-ups. Engineers verify trace connectivity with a multimeter to ensure no open/short circuits in the digital design. A prototype PCB is fabricated, populated with matching components, and tested functionally to confirm it matches the original’s performance.

Key benefits include legacy preservation (extending life of equipment with no digital records) and accuracy (direct physical reference minimizes design errors). When choosing a provider, prioritize expertise in physical data capture (X-ray, scanning tools) and functional validation to ensure the cloned PCBA mirrors the original.
