Mass production of 2D materials by intermediate …
21.10.2019 · The method, referred to as intermediate-assisted grinding exfoliation (iMAGE), can be used for the large-scale production of many 2D materials. As an example, we have exfoliated bulk h-BN into 2D h-BN with large flake sizes, high quality and structural integrity, with a high exfoliation yield of 67%, a high production rate of 0.3 g h −1 and a low energy consumption of 3.01 × 10 6 J g −1 .

Even slightly bowed inner layers are vacuumed on flat so they cannot slide during the later grinding process. The linear guides and adjustable grinding pressure create outstanding grinding results. This minimizes the risk of potentially grinding through the copper foil. The grinder head can be lowered toward the circuit board with a setting precision of 0.22 µm. The grinder head is moved ...
Four Tips for Manufacturing High-Volume …
UNITED GRINDING’s internal and external production grinding technology may provide a platform for high-volume manufacturing, but to achieve the necessary throughput, shops must approach mass production differently. Here are four key considerations as you consider scaling up production or perfecting existing high-volume processes: 1. To Go Big ...

Mass production back-grinding/wafer-thinning …
Abstract: The first mass-production back-grinding technology applicable to a fully-automatic wafer-thinning process in GaAs device manufacturing is described. Excellent productivity has been realized because the brittleness of GaAs has been overcome. A mirror-like stress-free surface was obtained by utilizing the wafer-rotating downfeed grinding method with slight stone etching.
