AOI inspection
Every layer pattern is compared against your data before it moves on.
Quality Is a Process, Not a Promise
Every board passes the same gauntlet: optical inspection after imaging, electrical test before it leaves, and a final human check at the end. Here is the chain your order goes through.
Electrical test
Flying-probe for prototypes, fixture testers for volume. Opens and shorts are found here, not at your bench.
X-ray and impedance
Inner-layer registration and impedance coupons checked on multilayer builds.
AVI and FQC
Automated visual inspection first, then people: final benches check finish, marking and count before packing.
Inspection follows IPC-A-600H Class 2. A board that fails a check is held back — you hear about it before anything ships, not after it arrives.
