Filed:

Jun 9, 2000

Appl. No.:

09/590018

Inventors:

Michael Lambert - Randolph NJ
Satish Chandra - Scranton PA
Tony Sosnowski - Stroudsburg PA

Assignee:

Laird Technologies, Inc. - Delaware Water Gap PA

International Classification:

B22F 310

US Classification:

428550, 427304, 427305, 427306, 427404, 4274431, 106 125, 106 126, 106 128, 428613, 428672, 428675, 428680, 428929, 428936

Abstract:

Provided are methods of preparing an electrically conductive polymeric foam. The methods include the following steps: (a) contacting a polymeric foam with a surfactant solution; (b) contacting the polymeric foam with a sensitizing solution; (c) contacting the polymeric foam with an activation solution; and (d) forming at least one metallic layer on the polymeric foam with an electroless plating process. Also provided are electrically conductive polymeric foams formed by such methods. The present methods and foams have particular applicability to the manufacture of EMI (electromagnetic interference) shielding devices.

International Classification:

H05K009/00

US Classification:

174 35GC, 179 35 MS, 361816

Abstract:

Disclosed are methods and apparatus for improving the resiliency and airflow through a honeycomb air vent filter while providing EMI shielding. In one embodiment, the honeycomb can be manufactured from a dielectric (e. g. , plastic) substrate to provide improved resistance to deformation as compared to conventional aluminum honeycomb. The dielectric honeycomb substrate is metallized to provide EMI shielding capability. The metallized honeycomb substrate is cut slightly oversize to fit an opening in an electronic enclosure, which results in elastic deformation of resilient perimeter spring fingers that are used to hold the metallized dielectric honeycomb in place and provide electrical conductivity between the metallized dielectric substrate and the enclosure, thereby eliminating the use of a frame. In another embodiment, additional conductive layers can be added to the metallized dielectric honeycomb. In yet another embodiment, the metallized dielectric honeycomb substrate can be utilized in a framed configuration to provide improved durability.

Filed:

International Classification:

B65D 732

US Classification:

220268

Abstract:

A stamped and scored one-piece container lid with an integral push-in tear tab has a ridge embossed in the tear tab and a push location to the rear of the ridge. When the push location is depressed, the tab tears along its score line and rotates into the container. The ridge prevents the user's digit from sliding along the declining tab through the opening in the lid left by the tab and possibly contacting the sharp edge thereof. Special indentations may be formed in the lid at or near the opposite ends of the score line which make it easier to depress the tab to produce a large effective pour opening in the lid.
