Device-surface choices move from wafer libraries to uniform coated samples.

Surface coating wafer

Coating changes stay on the circular wafer library before selected samples are repeated.

Follow-up pieces can represent glass, metal, ceramic, polymer, or optical-cover sample formats without copying a final product.

Decision problem

Device surface choices can consume prototype cycles when coating options are still broad.

Phones, laptops, watches, earbuds, cameras, and optical covers depend on surfaces that survive handling, fingerprints, cleaning, abrasion, humidity, corrosion, and cosmetic inspection. xemX can create measured physical samples before full device prototypes or supplier validation.

Customers can bring a device-cover, enclosure, decorative coating, anti-fingerprint, or supplier-sample question that needs early physical comparison.

Screening campaign

Compare related coating or process variants across a physical library before selecting the next device-test sample set.

Prototype coating project

Deposit selected coatings or controlled films on scoped substrates or coupons when the question is already narrower.

What can be measured

Optical response, color, surface change, corrosion response, hardness, conductivity, phase, texture, or stack compatibility.

What comes back

Measured coating maps, sample variants to repeat or reject, coated samples where realistic, and a shortlist for supplier or prototype decisions.

xemX can identify surface/coating variants worth making again and prepare selected samples. Full device integration, drop testing, cosmetic sign-off, and production qualification usually remain downstream.
