Reducing Product Mass

To minimize the use of resources for production, we continuously look to reduce the weight of our products.

Through the Product Environmental Assessment, Panasonic has been promoting resource saving from the product planning and design stage, such as using less resources, making our products lighter and smaller, and using less components. We also implement various measures from the standpoint of resource recycling throughout the product life cycle, such as component reuse, longer durability, use of recycled resources, easier battery removal, and labels necessary for collection/recycling.

4K LCD TVs

With respect to LCD TVs, we are working to reduce product weight by simplifying structures, reducing the thickness of materials, etc. In the FY2018 model for the Japanese market, TH-49EX600, the part for the metal fixing of the stand was widened to enable the stand to support the display by itself, making it possible to remove the metal frame for the stand which was required in the FY2017 model. Together with other efforts, this model also achieved a weight reduction of approx. 2.5 kg*1 compared with the FY2017 model.

Sheet-Form Encapsulation Material for Coreless Package Substrates

To make the size of mobile terminals such as smartphones more compact, it is essential to make the semiconductor packages thinner. Under such circumstances, Coreless package substrates are attracting attention in that they achieve thinner-profile and lower-cost semiconductor packages without the use of core material (copper-clad laminated boards). However, because thinner insulation layers cause greater warp of the substrate, there were issues in handling during installation or in assembling reliability.
Our sheet-form encapsulation material for coreless package substrates (CV2800 Series), whose mass production was launched in June 2016, achieved a reduction in the package warp as a result of its high rigidity and strength realized through our original design technology for fillers (additives/fillers) and resin. We will support the popularization by improving assembling reliability and contribute to downsizing products.

Example of Recyclable Product Design

For more efficient recycling, Panasonic works on designing products in line with the industry’s guidelines to achieve easier disassembly and sorting.
For example, use of fixing methods that are difficult to undo, such as welding and swaging, is minimized and the number of screws is reduced so that the products can be easily separated. In addition, materials used for resin components are indicated to facilitate sorting.
