A gang punch tool assembly and method is provided for punching holes in a plurality of greensheets which are processed sequentially through the assembly. The punch mechanism is a gang punch cooperating with a corresponding die and the greensheet is automatically fed to the gang punch and die, the greensheet punched and then the punched greensheet removed from the punch area and another greensheet positioned for punching. Operation of the gang punch apparatus is efficient and effective and has a high greensheet throughput. A preferred gang punch uses a pressurizable air chamber for controlling punching of the greensheet without damage to the greensheets or gang punch mechanism.

A coaxial connector having a conductive copper wire core plated with a layer of gold with the layer of gold surrounded by a dielectric layer, such as polyimide. The layer of polyimide is surrounded by a conductive shielding layer, such as copper, with a tin-plated layer surrounding it. Connection of the coaxial connector at one end to adjacent signal and ground pads is achieved by laser ablation to expose a section of gold sufficient to accommodate the terminal pad pitch and allow wire bonding to the signal pad. Connection of the conductive shielding layer to the ground pad is achieved by hot tip soldering. Connection at the opposite end of the coaxial connector uses the same process.
摘要:
The cracking experienced during thermal cycling of metal:dielectric semiconductor packages results from a mismatch in thermal co-efficients of expansion. The non-hermeticity associated with such cracking can be addressed by backfilling the permeable cracks with a flexible material. Uniform gaps between the metal and dielectric materials can similarly be filled with flexible materials to provide stress relief, bulk compressibility and strength to the package. Furthermore, a permeable, skeletal dielectric can be fabricated as a fired, multilayer structure having sintered metallurgy and subsequently infused with a flexible, temperature-stable material to provide hermeticity and strength.
