I-Tungsten Copper WCu Heat Sink
Incazelo
Izinto zokupakisha ze-Tungsten zethusi ze-elekthronikhi zinazo zombili izakhiwo zokunweba eziphansi ze-tungsten kanye nezakhiwo eziphakeme zokushisa ezishisayo zethusi.Okubaluleke kakhulu ukuthi i-coefficient yayo yokwandisa okushisayo kanye ne-thermal conductivity ingaklanywa ngokulungisa ukwakheka kwezinto okulethe ukukhululeka okukhulu.
I-FOTMA isebenzisa izinto zokusetshenziswa ezihlanzekile nezisezingeni eliphezulu, futhi ithola izinto zokupakisha ze-WCu zikagesi kanye nezinto zokucwilisa ukushisa ezisebenza kahle kakhulu ngemva kokucindezela, ukushisa okushisayo nokungena ngaphakathi.
Izinzuzo ze-Tungsten Copper (WCu) Electronic Packaging Materials
1. Izinto zokupakisha ze-electronic ze-tungsten zethusi zine-coefficient yokwandisa ukushisa okuguquguqukayo, engakwazi ukufaniswa nama-substrates ahlukene (njengalezi: insimbi engagqwali, i-valve alloy, i-silicon, i-gallium arsenide, i-gallium nitride, i-aluminium oxide, njll.);
2. Azikho izici zokuvula i-sintering ezingeziwe ukuze kugcinwe ukuqhutshwa kahle kwe-thermal;
3. I-porosity ephansi kanye nokuqina komoya okuhle;
4. Ukulawula usayizi omuhle, ukuphela kwendawo kanye nokucaba.
5. Nikeza ishidi, izingxenye ezakhiwe, futhi zingahlangabezana nezidingo ze-electroplating.
I-Copper Tungsten Heat Sink Properties

Ukusetshenziswa kweTungsten Copper Heat Sinks
Izinto ezifanele ukupakishwa ngamadivaysi anamandla amakhulu, njengama-substrates, ama-electrode aphansi, njll.;amafreyimu okuhola aphezulu;amabhodi okulawula ukushisa okushisayo kanye nama-radiator emishini yezempi neyomphakathi yokulawula ukushisa okushisayo.
