The Surface Grinder is mainly used in the finishing process. It is a very precise tool which uses a stationary, abrasive, rotating wheel to shave or finish a metallic surface which is held in place by a vise. This vise, which is part of a table, or carriage is moved back and forth under the abrasive wheel.
Wafer Back Grinding Process. FOB Reference Price:Get Latest Price 20191217Wafer backgrinding also referred to as backlap or wafer thinning is a process in which the backside of a wafer is ground down producing a thinner wafer that allows more layers and a higher density of integrated circuits to fit in a smaller package.

The backgrinding process involves using a diamond-resin bonded grinding wheel to remove the silicon material from the back of a silicon wafer. Using a grinding wheel is highly effective, and faster and less expensive than chemical-mechanical processes and is used to remove the bulk of substrate material prior to final finish grind, polish or chemical etch.

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.

The Truth About Back Cracking and Grinding. Back cracking can occur whenever the spine's facet joints are manipulated out of or into their normal position, such as when twisting the lower back or neck. When the facet joints move like this, they can produce an audible crack or pop along with a grinding sensation or sudden relief of pressure ...
