OverviewKoh-Young Meister S Series Semiconductor 3D SPI
The Koh-Young Meister S Series inspects micro solder deposits in semiconductor and Mini/Micro-LED packaging; S+ adds transparent-flux inspection. Select S for micro-solder measurement and verify S+ if transparent flux is required. Neither model substitutes for die-placement AOI.
One family · configuration choices
Compare Meister S Series versions
Measuring small printed solder deposits and, with the appropriate S+ optics, transparent flux before the packaging process continues. Select by the actual board envelope, optical configuration and installation space—not the suffix alone.
Additional material task

Buyer decision guide
When Koh-Young Meister S Series Makes Sense — and When It May Not
Koh-Young Meister S Series selection should begin with production requirements and evidence, not with a model name alone.
Application qualification
Koh-Young Meister S Series Acceptance Plan
Measure the deposit you actually print
For a Meister S qualification, provide the pad design, deposited material and independent height or volume reference. Include the smallest deposit and a representative bowed substrate. Agree measurement tolerance and repeatability before the demonstration. The quoted Z resolution describes the sensing system; it is not a promise of the same accuracy on every material.
Treat transparent flux as a separate requirement
An S+ offer should identify the special optics and show bare pads alongside flux-covered pads using the same recipe. Ask how low coverage, excess coverage and contamination are labelled. Do not accept a conventional solder-paste image as evidence that transparent flux was measured, or transfer a D+ reflective-die claim to the S+ configuration.
Preserve the height reference across a lot
Request the pad-referencing method, calibration history and a repeat scan before and after the sample lot. Review rejected deposits with the original measurement data, not only a coloured overview. For a used Meister S, establish which software and calibration support will transfer with the unit and which services need a separate agreement.
Typical Applications
Typical Applications for Koh-Young Meister S Series
Koh-Young Meister S Series should be evaluated against the buyer’s measuring small printed solder deposits and, with the appropriate s+ optics, transparent flux before the packaging process continues. The final application fit depends on the evidence for the specific unit.

FAQ
Common questions for overseas buyers evaluating a Koh-Young Meister S Series.
01Application
Which production task suits Koh-Young Meister S Series?
Measuring small printed solder deposits and, with the appropriate S+ optics, transparent flux before the packaging process continues. Select S for micro-solder measurement and verify S+ if transparent flux is required. Neither model substitutes for die-placement AOI.
02Configuration
What should a buyer confirm for Koh-Young Meister S Series?
Exact S/S+ optics, substrate handling, calibration and software permissions. Request the exact nameplate and option list.
03Unit evidence
Does this Koh-Young Meister S Series illustration prove stock?
The Koh-Young Meister S Series illustration is model-reference imagery, not a dated stock photograph. Serial, location, condition, price and running evidence require separate confirmation.
