3. Dimension

 

CH controls the overall package thickness.

 

When a  

window lid is used, dimension CH must increase by a minimum of  

.010 inch (0.254 mm) and a maximum of .040 inch (1.020 mm).  

4. The

 

corner shape (square, notch, radius) may vary at the  

manufacturer’s option, from that shown on the drawing.  

5. Dimensions

 

LW2 minimum and L3 minimum and the appropriate  

castellation length define an unobstructed three-dimensional space  

traversing all of the ceramic layers in which a castellation was  

designed. (Castellations

 

are required on the bottom two layers,  

optional on the top ceramic layer.)

 

Dimension LW2 maximum and  

L3 maximum define the maximum width and depth of the  

castellation at any point on its surface.

 

Measurement of these  

dimensions may be made prior to solder dipping.
