Current Challenges
Thin film deposition thickness is estimated empirically or theoretically.Excess deposition leads to wasted time and coating materials; insufficient deposition time results in inadequate film thickness.
Consumer Electronics & Industrial Protection
PCB Protection
Conformal coating: 3 um - 70 um, Moisture-, mold- and salt-fog protection for harsh-environment reliability
Surface Hardening / Decoration
PVD/CVD functional films (e.g. DLC): 50 nm - 5 um, Wear layers for phone mid-frames/watch cases; thickness affects durability and appearance

Frequently Asked Questions
What coatings are measured on consumer electronics and industrial parts?
Conformal coatings on PCBs are typically 3–70 µm and provide moisture, mold and salt-fog protection. PVD/CVD functional films such as DLC on phone mid-frames and watch cases are typically 50 nm–5 µm; thickness affects both wear life and appearance.
Why is empirical coating-time control a problem?
When thickness is only estimated from time or theory, excess deposition wastes cycle time and coating material, while too short a deposition leaves the film under-spec. Real-time thickness monitoring with compliance alarms replaces that guesswork.
How does in-process thickness monitoring save material?
Measuring film thickness during coating, with limit reminders and alarms, lets the line stop at the target thickness. That raises coating efficiency and cuts raw-material use compared with over-depositing “to be safe.”
Can the same metrology be used on industrial protection parts?
Yes. The same non-contact optical approach used on consumer housings applies to industrial protection films—for example flanges and observation ports—where wear or barrier thickness must stay in spec without damaging the coated surface.
