Photo‐Thermal Approaches on Polyimide Film for Demonstration of Sub‐50 µm Polymer Stencil Mask
Advanced Electronic Materials, EarlyView.A photo‑thermal approach enables precise control of polyimide film properties during UV laser processing, achieving stencil mask fabrication with feature dimensions <50 µm—with the smallest features measuring 42.4 µm. This method maintains the polymer in its glassy state during processing, resulting in exceptional pattern stability and reproducibility.

Effect of shielding gas composition and welding speed on autogenous welds of unalloyed tungsten plates [PDF]
arXiv, 2019 Tungsten usually exhibits poor weldability and marked brittleness at room temperature. This cause tungsten welds to be affected by the evolution of cracks along the weld bead, which can be eliminated by using a pre-heating step to reduce thermal straining.
