Boundary Scan Integration for High Density Circuit Assemblies
Boundary scan integration replaces physical test points with silicon registers, securing structural fault coverage on high density circuit assemblies.
Flying Probe Test Synthesis
Software Generation
Algorithmic preparation of electrical test instructions transforms electronic design files into coordinated movements for robotic probes. Flying probe test synthesis extracts physical coordinates and netlist connectivity from computer aided design files to generate a collision-free probe path. The output dictates the sequence of test points that mobile needles must contact on a circuit board.
Data Input
Input requirements for the compiler dictate the coverage and accuracy of the resulting test routines. The program ingests Gerber geometries, bill of materials data, and netlist formats to locate every testable node. During flying probe test synthesis, the software checks for access restrictions on component pads and detects coordinates that are shielded by high-profile components.
This phase must complete before physical test fixtures or test programs are run on the assembly line.
Program Optimization
Path planning algorithms calculate the spatial trajectory of each test needle to prevent physical collisions during high-speed movements. Because physical probes move sequentially across the circuit board, optimization of these paths reduces the cycle time for each board. Inefficient flying probe test synthesis generates unnecessary head movements, which increases machine wear and slows down the overall production throughput.
The synthesized program calculates the expected electrical limits for every trace to establish a pass or fail criterion for the circuit assembly. This automation reduces manual debug time when a board fails.
