Abstract

TEMPLEX* matrices for core plane assembly have been produced by photo-etching the cavities on a matrix bonded to an aluminum backing, washing out the matrix using standard washout procedures, machining off the aluminum backing and the adjacent bonded matrix to the desired thickness, bonding a grooved aluminum casting to the matrix to provide support for the matrix and vacuum passages to the etched cavities, and milling the X and Y wire slots in the matrix. This technique is not entirely satisfactory since it is costly and time consuming.

Manufacturing Core Plane TEMPLEX Matrices

TEMPLEX* matrices for core plane assembly have been produced by photo- etching the cavities on a matrix bonded to an aluminum backing, washing out the matrix using standard washout procedures, machining off the aluminum backing and the adjacent bonded matrix to the desired thickness, bonding a grooved aluminum casting to the matrix to provide support for the matrix and vacuum passages to the etched cavities, and milling the X and Y wire slots in the matrix. This technique is not entirely satisfactory since it is costly and time consuming.

This method comprises the following steps of photo-etching the cavities 2 in the matrix, milling X and Y wire slots above, vacuum hole development through the aluminum backing and matrix 3 to the desired depth, and cavity washout using standard washout procedures as above.

In this method, the bonding step is eliminated entirely. The aluminum backing is machined to approximately .020'' of the matrix, thus providing support for the matrix. Vacuum holes 3 are then milled through the remaining .020'' backing in registration with the cavities. Since washout is performed after milling operations are completed, burrs at the cavity walls are prevented thus eliminating picking and cavity distortion. *Trademark of E.
