Embodiment Construction
[0019] The present invention is achieved like this:
[0020] 1. According to the absorption spectrum characteristics and labeling requirements of the package and protective layer, the producer uses anthraquinone or azo or phthalocyanine compound powders with different absorption spectrum characteristics to produce anthraquinone or azocyanine compound powders that produce the required absorption spectrum characteristics. Mixed powder of nitrogen compounds;
[0021] 2. The producer produces an active p-xylene dimer mixed gas containing precursors with adjustable absorption spectrum characteristics;
[0022] 3. Drying, degassing, purification and activation of integrated circuit chips, electronic devices, circuit boards or functional materials by the producer;
[0023] 4. The producer flows the active p-xylene dimer mixed gas containing precursors with adjustable absorption spectrum characteristics to the surface of integrated circuit chips, electronic devices, circuit boards or...
