Positive Pressure Leak Calibration Device
There are two types of standard leak holes: one type, one end of the leak hole is vacuum and the other end is an atmospheric pressure leak, which is called a vacuum standard leak; the other type, one end of the leak is added to the other end of the leak. Leakage gas is often called a positive pressure standard leak.
Microwave plasma chip unsealing equipment
Chip unsealing is also called unsealing, opening cover and opening cap. In the process of unsealing, the lower filler (the main component is epoxy resin) in the interconnection structure is mainly removed, so that the wire bonding or the chip itself is completely exposed.
Hot filament HFCVD diamond deposition device
Hot wire chemical vapor deposition (HOT FILAMENT CHEMICAL,VAPOR DEPOSITION,HFCVD) technology is one of the commonly used diamond film deposition technology, with simple equipment, convenient operation, low cost, suitable for large area, complex shape tool diamond coating deposition and other advantages.
Expansion method vacuum device
This vacuum standard device is mainly used for verification/calibration of capacitance film vacuum gauges and thermocouple vacuum gauges in the range of (1.3 × 105~1.3 × 10-1) Pa. It mainly has the following characteristics: The 1.1 takes into account both the comparative method and the expansion method, which is convenient for customers to master flexibly and ensure that the equipment can be used for a long time; All instruments and equipment selected as part of the 1.2 expansion process provide a long term warranty. The standard capacitor film gauge for comparison method is guaranteed by the original factory. 1.3 using special software for data acquisition and processing, high efficiency; The 1.4 system software is upgraded free of charge for life, and the overall level of the device has reached the domestic advanced level.
