Applications

RADIANT HEAT SOLDERING – TABBING MACHINE

Process Sensors’ Model PSC-CS-Laser- LT thermometer with built- in dual lasers provides pinpoint sighting and used in a 2 wire loop powered configuration. The 4-20 mA linear output signal integrates easily into recording and process control instrumentation. A built-in peak picker is provided for intermittent, moving targets.

LASER WELD & ELECTRICAL BIAS INTERCONNECT TESTING

Process Sensors’ Surveyor on-line camera provides a real time picture of thermal gradients that indicate defective welds and faulty interconnects. Interchangeable lenses and Windows based software facilitate data acquisition and automatic control functions. The compact size of the Surveyor camera is ideal for use in test station configurations and tight locations.

CdTe CELLS – THIN FILM DEPOSITION

Thermometer Compact Series models DT40-G or DT44-G sensors precisely measures the glass substrate surface temperature during deposition. The Metis model MP23 or PSC-SSS-Laser 3M series have the capability to measure the temperature of the deposition / TECO coating through the glass substrate.

DIRECTIONAL SOLIDIFICATION CASTING

Process Sensors Metis model MS thermometers accurately measures the temperature of the molten silicon and insures that the liquid / solid phase change has occurred to initiate the next step in the process. The pyrometer is used to measure temperature and provide feedback to control power to the heaters. This insures that the growth process is optimized.

SILICON CRYSTAL PULLING (CZOCHRALSKI / FLOAT ZONE PROCESS)

Metis Series models MS single wavelength, and MQ 2 color ratio thermometer monitor the melt meniscus and susceptor to provide accurate temperature data for pulling rate control. Precision aiming and focusing is achieved through the use of focusable optics and advanced sighting capabilities such as through the lens, laser or video. Analog and digital outputs interface conveniently with control and data acquisition instrumentation.

CVD REACTOR (SEIMENS PROCESS)

Metis model MQ, 2 color ratio thermometer in Class 1 Div I, Group B explosion proof housing with direct or fiber optic versions for hard to reach locations, provides the precise temperature measurement during deposition needed to ensure controlled growth rate and uniformity.

POLYCRYSTALLINE CASTING

Metis Series model MQ, 2 color ratio thermometer, or model MS single wavelength thermometers, measure melt temperature with precision during the critical solidification phase to ensure the specified crystal orientation, size and homogeneity. The ratio measurement technique is not affected by partial obscuration of viewport sighting windows and vapors in the Infrared thermometers sight path.

CIGS CELLS – THIN FILM DEPOSITION

Metis model MS09 has a narrow band, short wavelength spectral response to minimize the effects of highly reflective, variable emissivity targets, such as are true of the aluminum and steel substrates encountered in CIGS thin film deposition process.
