Automated devices, definition

The comprehensive definition for a chemical sensor is a device that transforms chemical information, ranging from the concentration of a specific sample component to total composition analysis, into an analytically useful signal [3]. However, the chemical sensors are the far better system than the standard analysis of chemical in terms of (1) produce a qualitative output, (2) can often be easier to automate, and (3) can be used in real-time analysis. For various chemical sensors different operating... 

Odd-Form Components. The odd-form cximponents are the last devices to be assembled on the circuit board. Odd-form components, by definition, are those packages that are not readily addressed by automated assembly because (a) they are used at insufficient volumes on the product to justify machine space or (b) they are of a geometry (shape or size) that lacks the customer demand to justify the machine manufacturer to provide off-the-shelf tooling for them.
