A Powerful Tool to Accelerate In-Circuit Test (ICT) Program Development


VayoPro – Test Expert could generate test program for leading In-circuit test (ICT) equipment like Keysight (i3070, i1000), Teradyne test station (GR 228x), TRI (TR518, TR5001, TR8001), Spea (T300, 3030IL), Seica (Next), …

VayoPro – Test Expert not only comes with typical nail selection & tester output function, but also comes with unique function for In-circuit test (ICT)  program generation.

With step-by-step workflow, a humanization design part of this softwarem, you will never forget which step should be the next and could easily get the final report following this flowchart.

VayoPro – Test Expert allows you to maintain multiple rule sets, and execute nail selection together, then compare the difference and easily choose best result for fixture design & program generation.

A unique feature among the industry—Nail Correctness Check. By importing the Soldermask layer and align with the CAD data, untestable points can be automatically detected, as well as new test points.

VayoPro – Test Expert could automatically extract component value and tolerance from BOM description.

VayoPro-Test Expert can virtually merge multiple nets to one net to achieve a higher testability, and reduce test nails.  For nets connected via small value resistor, switch or fuse, we could treat them as one net; VayoPro – Test Expert has a function called Net link, which could merge those nets into one virtual net.

Sometimes, component’s body would be drawn too big, causing the nail too close to part body, which may lead to an inaccessible net. Our VayoPro – Test Expert could list such components that cannot be tested due to too-large body size, and then directly reset the size of component body.

By complishing all above configuration, our VayoPro – Test Expert could output several kinds of programs. Such as ICT/MDA: Teradyne / GenRad, Agilent / Keysight, TRI, Checksum, JET, Hioki, IFR, SRC; Flying Probe: Takaya, Seica, Acculogic, Digital Test; AXI/AOI: Agilent 5DX, ViTrox V810, Omron, VI Technology, Orbotech, TRI,…

Also, you could choose different output requirements aligned with different needs.
