Title:
MICROELECTRONIC COMPONENT CARRIER AND METHOD OF ITS MANUFACTURE
Document Type and Number:
WIPO Patent Application WO1999017317
Kind Code:
A8
Abstract:
A microelectronic component carrier package (100) and method of its manufacture. A nonconducting component carrier having vertical risers (110) and guide channels (108) permits the rapid and accurate routing of microelectronic component leads with respect to a leadframe (104). Specially shaped perforations (116) in the leadframe (104) adjacent to and aligned with the guide channels (108) receive the leads, strip away the necessary amount of insulation, and sever the leads (124) to the proper length in one manufacturing process step. The leads are joined to the leadframe (104) by an interference fit, convention bonding technique (such as solder or thermal compression bonding), or other technique. The perforations (116) further provide for stress relief of the leads in the assembled package, and permit the joints between the leadframe (104) and leads to reside outside of the package, thereby minimizing the overall volume of the package. The perforations (116) may also be used as masks for laser energy used to strip insulation from the leads in the vicinity of the perforations (116).
