Application Guide for Younikon Technology Filmetrics Film Thickness Measuring Instrument
In modern production, quality control, and research and development innovation,Optical film thickness gauge(i.eFilm thickness measuring instrumentOr abbreviated asfilm thickness gauge）It has become an indispensable precision testing tool. asYounikon TechnologyagentFilmetricsThe series film thickness gauge, with its superior optical interference technology, is widely used in fields such as semiconductor wafers, optical coating, industrial coating, and material surface treatment. In order to help every user fully utilize the performance of the equipment and extend the service life of the instrument, we have compiled the following systematic operating specifications and detailed points, which are recommended to be included in the daily operation manual based on the actual situation on site.
Before starting any measurement, please make sure to check the surface condition of the object being measured.Optical film thickness gaugeEspecially based on the principle of optical interferenceFilm thickness measuring instrumentVery sensitive to the flatness of the sample surface. If there are obvious bends, warping, deformations, or severe scratches on the surface, it will cause the probe to be unable to stably couple with the surface, the focus of the light spot to shift, or the reflection signal to be abnormal, ultimately directly affecting the measurement accuracy.
Choose flat and clean areas as testing points as much as possible; If it is necessary to measure curved surfaces or irregular parts, please use the matching specialized fixtures and positioning tools, andYounikon TechnologyUnder the guidance of engineers, perform curvature compensation or algorithm adaptation.
Before testing, gently wipe the surface of the sample with a dust-free cloth or specialized cleaning agent to remove any attachments such as oil, sweat, dust, etc., and avoid contact with itfilm thickness gaugeDuring measurement, a "false layer" is formed to interfere with the data.
For wet film detection of volatile components in coatings, inks, adhesives, etc., usefilm thickness gaugeThe rhythm of operation is particularly crucial:
Measurement should be completed as quickly as possible after coating, as rapid solvent evaporation can cause the actual thickness of the film layer to continuously decrease, and the surface state also changes during the leveling process. Suggest planning and setting up testing points in advanceFilmetricsThe parameters of the film thickness gauge are quickly collected at multiple points after coating, and if necessary, the average of multiple measurements is taken as a reference.
For samples with high viscosity or fast curing speed, simulation exercises can be conducted in advance to familiarize oneself with themFilm thickness measuring instrumentThe response time ensures the timeliness of data capture.
If measuring multi-layer composite films, transparent films, or rough surface coatings, it is necessary to correctly select or pre establish corresponding measurement models for the optical constants (refractive index n, extinction coefficient k) of different materials. Master the material characteristics of the substrate and film layer, and selectOptical film thickness gaugeThe matching algorithm pattern is the core to ensure data accuracy.
Do we need to establish a measurement model for special film layers?
Engineers from Younikon Technology can assist in developing customized algorithm solutions to ensurefilm thickness gaugeAccurate and reliable data.
Obtain technical solution supportOptical film thickness gaugeAs a precision optical measurement device, its sensor window, lens, fiber optic interface, etc. require extremely high cleanliness.
Before and after each use, a specialized cleaning tool (such as a dust-free wiping stick or lens cleaning solution) should be used to gently wipe the measurement probe window and standard film. It is strictly prohibited to directly wipe with ordinary paper towels or organic solvents to avoid scratchesFilmetrics film thickness gaugeOptical coating or corrosion of optical components.
After using the instrument, it should be stored in a moisture-proof cabinet or sealed box, with desiccants placed inside and replaced in a timely manner. The storage environment should be kept away from water sources, heat sources, acidic and alkaline gases, and strong vibration sources.
When not in use for a long time, it is recommended to perform power on preheating, self inspection, and standard calibration once a month to prevent the circuit from getting damp and the optical components from becoming moldy, ensuringfilm thickness gaugeAlways on standby.
There is no single measurement method suitable for all samples. Operators should systematically learn and master the detection schemes for different substrates (such as silicon, glass, metal, polymer) and different types of film layers (such as oxides, nitrides, photoresists, metal films, coatings, etc.). Suggest establishing a 'sample testing matrix' to incorporate common product materials, film structure, reference measurement modes, calibration methods, etc. into standard operating procedures (SOPs) to reduce manual switchingFilm thickness measuring instrumentIncorrect operation during setup.
For composite film layers with unknown components, a small sample can be used to explore the conditions first, and with the help ofYounikon TechnologyAfter the technical support clarifies the optimal measurement wavelength, reference loop, or algorithm, it can be extended to batch testing.

It is recommended toOptical film thickness gaugeInstalled in areas with high cleanliness (such as Class 1000 or Class 10000 cleanrooms, or equipped with clean workbenches), to prevent suspended particles such as dust, oil mist, and fibers from depositing at the optical interface.
Control the environmental temperature and humidity, with an ideal temperature range of 20 ± 2 ℃ and a relative humidity of<60% RH (no condensation). Large fluctuations in temperature and humidity not only cause thermal expansion and contraction of the sample, but also may cause fogging inside the optical components, leading toFilm thickness measuring instrumentMeasure drift.
