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.
The PSM 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.
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.
The PSM 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.
