Programmable Sample Monitor

Category: Accessories

Description

Key Features

Programmable material removal
Continous display of material to be removed with 1 micron resolution
Optional automatic machine cut-out
Audible alarm

The Logitech PSM Programmable Sample Monitor is a high precision sample monitoring facility designed for use with PP5, PP6 and PP8 Precision Polishing Jigs. It provides an effective means for automatic processing of samples to a pre-determined programmed thickness. Due to the audible alarm feature on the PSM, which activates prior to completion of sample processing, and the optional infra-red cut-out, the unit can be left to run unsupervised – freeing the operator to perform additional tasks.

Construction
The Programmable Sample Monitor system consists of a sample monitor and digital linear gauge (DLG), which replaces the mechanical dial gauge normally fitted to a PP5, PP6 or PP8 jig. Both units are mounted directly on the jig and can be fitted to both new and existing jigs with the minimum of modifications.

Operation
Before placing the jig on the lapping or polishing machine, the amount of material to be removed is entered into the sample monitor unit. The jig is then placed on the machine and on pressing the RUN button, the sample monitor takes a zero reference from the digital linear gauge and displays the amount of material to be removed. It continues to display this information throughout the whole process.

Applications
The Programmable Sample Monitor system is ideal for all applications where the requirement is to produce a highly uniform specimen with a precisely controlled final thickness to within 1µm. Typical applications are ultra-thin section production, backlapping and polishing of semiconductor wafers and opto-electronic materials or surface preparation of crystals or surfaces on samples at chosen angle.

Geological Sciences

In many areas of geological study such as mineralogy, petrography and sedimentology you are required to analyse the characteristics of the materials such as soil or rock. To be able to do this a thin section needs to be prepared for microscopic examination.

Logitech precision equipment is ideal for thin or ultra-thin section preparation. Our wide range of versatile systems enable you to trim, lap and polish geological thin sections such as rock, coal, concete and soils.

Each of our systems are fully supported by a wide range of accessories and consumables, such as abrasive powders, polishing cloths and mounting media.

Semiconductors

Semiconductor materials are used in a wide variety of devices such as field effect transistors (MosFets, Fets), integrated circuits (ICs, MMICs, ASICs), focal plane arrays and infra-red detectors.

Whatever the application or material, each semiconductor wafer undergoes several common stages during manufacture, which include slicing the wafer from the crystal, preparing the surface prior to fabrication and thinning the device after fabrication through the use of lapping and polishing techniques.

Logitech provide complete system solutions including consumables for the precise thinning of these III-V, I.R. and similar materials.

CMP Applications

Primary applications areas are in the field of Tribology Science and Research, particularly with regards process and analysis results. For example co-efficient of friction monitoring (CoF).

The Tribo chemical mechanical polishing system is also readily adaptable as an enabling technology in Microelectromechanical Systems (MEMS) fabrication, particularly polysilicon surface micromachining, Opto-MEMS and Bio-MEMS packaging, assembly and even fabrication.

Optoelectronics

Advances in communication technology have led to the development of a wide variety of optoelectronics and integrated optics devices for applications such as; dense wavelength division multiplexing (DWDM), optical isolators, signal processors and optical switching.

Logitech has a large selection of adaptable systems for the preparation of optoelectronic materials such as; silicon, lithium niobate, lithium tantalate, bismuith silicon oxide, barium titanate and similar materials.

Our systems, accessories and consumables provide defect free face and edge polishing on optoelectronic substrate and scratch free surfaces with exacting and repeatable dimensional tolerances.

Optics

The importance of optical polishing and the processing of optical components has never been greater with the ongoing development of the telecommunications market. Whether for Infra Red and polymer waveguide production or fibre optic cable polishing.

The precision design and manufacture of our equipment enable you to obtain maximum results from the cutting, lapping and polishing of these optical materials.

Other Applications

Logitech Material Processing Specialists

Logitech systems are used by organisations across the world for many different complex sample preparation processes.

Including the thin section preparation of; Teeth, Bone, Otoliths, Ceramics, Metals, Alloys, Polymers and other Carbon-based materials.

DIAMONDS ARE AN ENGINEER’S BEST FRIEND

In recent years, diamond has emerged as not only a girl’s best friend, but also as contender as an engineer’s best friend – if the technical challenges of exploiting its remarkable properties can be overcome.

THE END OF THE CHIP FOR SILICON?

Silicon-based semiconducting integrated circuits have changed the world immeasurably over the past 50 years. Today the number of silicon chips in use far outweighs the number of humans currently alive.

OPTIMAL FRICTION FOR OPTIMAL FLATNESS

The wafers used to make semiconducting chips for electronic devices all have one thing in common – they need to be smooth – super smooth. Typically, wafer flatness needs to be controlled within ±2 μm.
