Alpha-2TM Surface Mount Package Handling and Mounting
Millimeterwave components require careful mounting design to maintain optimal performance. Alpha-2TM surface mount packages (patent pending) provide a rugged and repeatable electrical connection using standard solder techniques. The -A3 package is one of several parts in the Alpha-2TM surface mount package family.

Handling
The -A3 surface mount package is very rugged. However, due to ceramic's brittle nature one should exercise care when handling with metal tools. Do not apply heavy pressure to the lid. Vacuum tools may be used to pick and place this part. Only personnel trained in both ESD precautions and handling precautions should be allowed to handle these packages.

Footprint Geometry for -A3 Surface Mount Package.
Mounting the Package
The -A3 surface mount package is compatible with highvolume surface mount installation using solder. RF and DC connections are accomplished with metallized edge castellations that hold solder fillets. Ground connections are accomplished by both metallized edge castellations and filled vias to the bottom of the package. Care should be taken to ensure that there are no voids or gaps in the solder so that a good RF, DC, and ground contact is maintained.
Package Construction
The -A3 surface mount package consists of a base and a lid. The package base is ceramic with filled vias and plated castellations. The package lid is un-plated alumina. The lid seal is epoxy.
Mounting Design
The -A3 surface mount package is installed on top of a printed circuit board on a specially designed footprint. Mounting footprint geometry for the -A3 package will be supplied by Alpha Industries in electronic formats or paper drawing.
