Fixtures and tooling

All fixtures and tooling for assembly and disassembly shall be ineluded in the seope of supply. 

Never use wooden mallets, brittle or chipped tools, or dirty fixtures and tools when bearings are being installed. 

The fixturing and tooling requirements differ for both the fixed-pin and adjustable selfreacting (ASR) pin tools (Fig. 13.4). The fixed-pin configurations require an internal mandrel...

Deposition process-related - e.g. contaminant vapors and particulates from vaporization sources, fixtures and tooling. 

Often, material utilization in an evaporation process is poor unless proper fixturing and tooling is used to intercept the maximum amount of the flux. This can be accomplished by... 

Wear particles can be generated from fixturing and tooling in the deposition chamber. Fixturing and tooling should be designed so that wear particles do not fall on the substrates. System vibration increases the particle generation. 

Often the best way to handle surfaces is to mount them in fixtures so that the active surfaces are not contacted directly. The next best technique is to use mechanical tools to hold and handle the surfaces. Often, fixtures and tools can be designed that prevent surfaces from being touched in critical areas, giving abrasive transfer between surfaces. Abrasive transfer can be a problem even with metal tools. For example, a clean oxide surface will easily transfer chromium from chromium-plated tools to the clean surface if there is abrasion. A protocol has to be established as to when and how to clean, store, and use the tools, and what to do with them when they become contaminated.
