The Sidebraze Package, is one of the most mature IC packages still in use today.  It is a rectangular ceramic package that has leads extending from both of its longer sides, thus forming two sets of in-line pins.  It is therefore a type of dual-in-line package (DIP).  Two other widely used DIP's are the PDIP and the CerDIP.

Like the cerDIP, the sidebraze package is a hermetically sealed package that keeps out moisture and contaminants once it is sealed. Unlike the cerDIP which has separate upper and lower ceramic bodies, the sidebraze package has a single ceramic body.  This single body has a cavity on top where the chip is placed and bonded.  The sidebraze package is hermetically sealed with a metal cap. 

Sidebraze package lead counts range from 8 to 48.  Sidebraze packages usually have a body width of  either 300 mils or 600 mils. However, 400- and 900-mil body widths do exist. The lead pitch of a sidebraze package is typically 100 mils.
