Abstract: A package for housing an electric or electronic component is disclosed. The package includes a base and a header that includes a top portion and a support portion. The support portion has a first and a second end that defines a first and a second opening respectively. The top portion is secured to the first end and covers the first opening. The top portion includes a header vent to allow a substance (e.g., air, water, etc.) to flow into or out of an interior of the package. The header is configured to house the component therein. The header can be placed into a circular hole of the circuit board. The base is secured to the second end of the support portion, and is configured to secure the package to the circuit board. The vent can minimize moisture within the package and/or drain liquid from inside of the package.
