Micros focus on vacuum coating plant

Microprocessor in wafer probe The Electroglas Model 2001 .X from the USA is a new microprocessordriven modular wafer prober which can be interfaced with any tester and is upgradeable from the basic machine to provide fully automatic operation. The 2001 .X is constructed using the Xynetics Sawyer principle with a low chip count and a selfdiagnostic capability. An important feature is the linear motor which drives the X - Y stage, and the high-torque Z-stage has a resolution of 0.1 thou. In its programmable mode, the Electroglas is controlled by noncontact capacitive edge-sensing, and in fully automatic mode provides prealign fiat finding, cassette-to-cassette loading and works in alignment with a TV pattern recognition system. Pattern recognition alignment references to unique patterns within each die. The basic wafer prober module includes RS232/IEEE-488 external communications capability and is expandible with a material handling module which includes prealign station and wafer transfer and input/ output indexers. Further expansion is possible with the automatic alignment module with pattern recognition hardware and software. (Electroglas, 2901

Dispense with micros Scriptcounter is a label-printing and stock control computer for pharmacists. Based on a 6502 processor, it was designed for Taylor Nelson Medical by Maidenhead consultants Micro Scope. It is also Micro Scope's first venture in manufacturing. The selfcontained unit comprises a 40-character Hitachi LCD, two 26character printers (one for standard labels, the other for red 'not to be taken' labels), a digital cassette recorder and a QWERTY keyboard. The pharmacist can type in Latin acronyms which are expanded into full drug names and dosage instructions on the label. All in!:ormation, except the patient's name, is recorded on the digital cassette for subsequent

cations and control system is built around the Texas Instruments TM 990 control processor and enables the automatic running of a vacuum coating plant. The system can operate plant and operational mode without computer language. Computation anddisplay of theoretically possible spectral graphs on the basis of process data input can be achieved as well as graphic display of spectral curves of changes in pressure, temperature, emission, etc. Other features include • storage of process data for many layer systems • selective control of a maximum of eight evaporation sources with a maximum of eight different vapour deposition materials • onsite software and hardware modification • manual override The Leycom system is suitable for batch processing of optical filters particularly for scientific and military applications such as lasers.
