dry etching generally refers to methods like laser etching, where a high-power laser is used to ablate copper from the underlying substrate to create traces, or plasma etching, which uses RF ...

[Frankie] and [Bryan] have figured out a way to use the laser to chemically activate an etching process. See experiment part 2 as well. First, to be clear, they are using a quality 40W Epilog Zing ...

Three laser experiments today: laser-induced electroless copper plating ... I'm using a "20W" 450nm blue laser etching machine for these experiments, and while a bigger or pulsed laser would ...

Copper’s optical absorption of blue light ... The thickness and composition of the layers, and the size and shape of the laser etching, can all be chosen to determine the laser’s properties ...

According to market analyst Boston Consulting Group, the market for advanced microchip packaging is expected to grow to more than 96 billion dollars by 2030. For Trumpf and Schmid, advanced packaging ...

Advanced packaging with glass is a crucial future technology for the semiconductor industry. Glass is significantly cheaper than silicon. This will enable manufacturers to reduce production costs and ...
