Project Description
Alloy Replacement Quartz Monitor Crystals 5 MHz and 6MHz AT-Cut for Thin Film Vacuum
Our AT-Cut replacement quartz monitor crystals are an excellent choice to enhance your process and help you maintain a lean consumables budget. We sell a wide range of replacement quartz monitor crystals for most commercially popular film thickness monitoring systems (including Inficon, Maxtek, Sigma Instruments and Sycon Instruments). Our quartz monitor crystals are manufactured to the original manufacturer’s (OEM) specifications. In most cases we exceed theses OEM specifications and quality controls to provide you with replacement consumables you can thoroughly trust.
Note
Replacement quartz crystal sensors used for thin film thickness monitors and controllers (including Inficon, Maxtek, Sigma Instruments and Sycon Instruments). Alloy electrode quartz monitor crystals are recommended for high-stress deposition, such as optical coating with dielectric materials and semiconductor processes with high-stress materials
SPECIFICATIONS

SungThai offers both 5 MHz and 6 MHz AT-cut quartz thickness-monitor crystals. These products are offered with gold, silver, and alloy coated electrodes for major optical and vacuum coating applications, PVD, and for use in thin film deposition processes.
SungThai quartz thickness-monitor crystals are suitable to be used in different kinds of vacuum coating equipment of high accuracy such as Inficon™, Ulvac™, or Balzers™.
Our 5 MHz products are commonly used in Japanese market or coating devices made in Japan, and 6 MHz products are most widely used by customers.
Advantages of Alloy Quartz Monitor Crystals , Double anchor,5 MHz and 6MHz,AT-Cut,for Thin Film Vacuum
Our product manufacturing system includes demanding requirements for military and aerospace applications. Longevity, stability, accuracy and interference protection are inherent traits of our products. Good quality results from strict process management, not only from 100% testing in the factory.
Our products originate from a dedicated quartz crystals component manufacturer with a history of 60 years which is specialized in manufacturing quartz monitor crystals for 30 years. You don’t worry that our products are outsourced from any third party manufacturer. Direct sales from the manufacturer ensure reliable supply and provide competitive price. Apart from supply of standard products, we can customize products depending on your need.
By using high quality quartz bars with long growth cycle and high Q value, we control product quality from the very beginning of manufacturing process.
Since 1980’s, we have introduced or customized state-of-the-art coating machines, so that our crystals have better density and adhesion with highly competitive deposition accuracy in the industry.
High-end piano allows for better performance; but a person without long-term special training cannot make excellent products no matter what high-end machines he uses. Our engineers are our core competitiveness; thanks to expertise accumulated for 30 years, our engineers can make use of modern equipment, manufacturing system and excellent technology to manufacture quartz monitor crystals with superior quality.

Why they choose Alloy Quartz Monitor Crystals , Double anchor,5 MHz and 6MHz,AT-Cut,for Thin Film Vacuum
China manufactures about 80% of quartz crystals products in the world; SungThai product team is the developer of Chinese national industrial standard, and is the technical leader.
In 1980’s, we have known that their crystal components have good reputation in international market; their precision equipment and manufacturing process are excellent.
Once aerospace devices are launched into space, any problem in any part will result in failure of the mission; SungThai products have experienced many great space programs, and have delivered good performance up to now. We trust SungThai.
Our engineers are very skillful and experienced; in the past, we bought economical products with short service life; by replacing them more frequently, we can get similar results as the precision products. Now, we don’t need to do so because SungThai offers precision products at economical price. Our engineers are much easier.
SungThai uses first-class quartz bars with long growth cycle and high Q value as the raw materials; doubtless, it greatly improves the quality of quartz monitor crystals.
SungThai’s coating machines are customized special magnetron sputtering equipment, providing very high density and strong adhesion in contrast to our previous products.
All products manufactured from SungThai are 100% tested; having been used for many years, the products work well without any problem.

Convenient packages
Black flat-pack carousel dispenser with vacuum plastic bags-holds 10 crystals which are extracted by vacuum pencil or dispensed directly into holder
Clean room quartz crystal package enables convenient dispensing of the crystals directly from the package to the sensor, minimizing operator handling and risk of contamination. To make the crystal package more cleanroom-friendly, we eliminate the paper and foam inserts and make the packages stackable for easy storage.
