What’s SBDIP Package?
Sidebraze Dual-In-line Package (SBDIP) 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 others widely used DIPs 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.
SBDIP package’s lead counts range from 8 to 48. The 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 is typically 100 mils.
