发明名称 Method of manufacturing RF power semiconductor package
摘要 High frequency power transistor carriers are made by bonding a metalized ceramic base to a lead frame strip, subsequently gold plating the resultant structure and then cutting the lead frame strip to isolate the base and collector leads while still maintaining the transistor carriers in strip form. Transistor dice are then attached to each ceramic carrier, and each transistor carrier in the strip is then electrically tested. The individual carriers are then separated from the lead frame strip. The individual carrier has wide base and collector leads extending outward from the ceramic base for a substantial distance and then the base and collector leads are narrowed down. When the individual transistor carrier is used in combination with a hybrid assembly, a reduction in lead inductance and total hybrid package size is obtained while exact carrier placement relative to the hybrid assembly is not required.
