Wafer Backgrind Wafer Backgrind is the process of grinding the backside of the wafer to the correct wafer thickness prior to assembly. It is also referred to as 'wafer thinning.' Wafer backgrinding has not always been necessary, but the drive to make packages thinner and thinner has made it indispensable.
Design Assembly Drawing When a machine is designed, an assembly drawing or a design layout is first drawn to clearly visualise the performance, shape and clearances of various parts comprising the machine. Detailed Assembly Drawing It is usually made for simple machines, comprising of a relatively smaller number of simple parts.
machine spindle and grinding wheel and the use of an electrolyte instead of a coolant. The tool the grinding wheel is the () of the electrical source and the part being machined is the (+). The technique is applied in machining carbide tools and alloy tools, carbide steel .
The basic drawing standards and conventions are the same regardless of what design tool you use to make the drawings. In learning drafting, we will approach it from the perspective of manual drafting. If the drawing is made without either instruments or CAD, it is called a freehand sketch. Figure 12 Drawing Tools. "Assembly" Drawings
· jigs and fixtures are the devices which help in increasing the rate of identical parts and reducing the human efforts required for producing these parts, It has already been emphasized earlier that a center lathe is a suitable machine tool for producing individual parts of different shapes and sizes, but for producing similar articles in great number its use will not be economical.
