The SEICA Pilot 4D M4 is a premier, next-generation flying probe test platform engineered for sophisticated reverse engineering, electronic board testing, diagnostics, and comprehensive validation. Employing four ultra-precise, high-velocity probes that dynamically traverse PCBs without reliance on test fixtures, it offers unparalleled flexibility ideal for low- to medium-volume production runs, prototyping, and complex repair operations. Integrated with advanced 4D test technology, the system synthesizes electrical, optical, thermal, and mechanical measurements to provide exhaustive fault coverage on densely populated and multilayered circuit boards. Its agile, fixtureless design significantly reduces setup times while maximizing diagnostic depth and throughput. Esteemed across critical industries such as aerospace, defence, and high-tech manufacturing, the SEICA Pilot 4D M4 embodies cutting-edge precision, reliability, and operational excellence in electronic assembly testing.
