JJK focuses on 5MHz and 6MHz Quartz Crystal for thin film thickness monitors. Available in gold, alloy and Silver. Excellent for vacuum evaporation optical coating .Well performance in thin film thickness deposition rate control. Our products quality is equivalent to Inficon, Ulvac, Filtech, etc. Applied to different kinds of vacuum coating machines from American, Germany, Japan and Switzerland.
Choosing the right crystal:
Our continuing research into quartz crystal characteristics results in ongoing improvements to offer the highest reliability in your process.
We recommend gold crystals for the most applications. However,silver crystals will provide superior performance in processes with the high heat loads,such as sputtering.They may also improve the deposition of oxides.And alloy crystals are recommended for optical coating with dielectric materials and for semiconductor process with high-stress material.
