Emhlabeni othuthukayo wezinto zikagesi, ama-PCB weSemiconductor (Amabhodi Omjikelezo Aphrintiwe) ami njengezakhi eziyisisekelo eziqhuba ukuqamba kanye nokusebenza ezimbonini eziningi. Noma ngabe wakha amagajethi wabathengi asezingeni eliphezulu, amasistimu ezimoto asezingeni eliphezulu, noma amadivaysi okunakekelwa kwezempilo abalulekile, ukuqonda ama-PCB we-Semiconductor kubalulekile. Kwa-Highleap Electronic, inkampani ephambili ekhiqiza i-PCB kanye nomhlinzeki womhlangano, sisebenza ngokukhethekile ekuletheni ama-PCB e-Semiconductor ekhwalithi ephezulu enzelwe ukuhlangabezana nezidingo zakho ezihlukile zephrojekthi.

Iyini i-Semiconductor PCB?

I-Semiconductor PCB iyibhodi lesifunda eliphrintiwe elikhethekile elakhelwe ukusingatha futhi lixhumanise ama-semiconductor amadivaysi afana namasekhethi ahlanganisiwe (ICs), ama-transistors, nama-diode. Lawa ma-PCB asebenza njengomgogodla womshini nokagesi wezingxenye ze-semiconductor, okubenza bakwazi ukusebenza ngokuhlangana ngaphakathi kwamasistimu kagesi.

Ukuqonda amaSemiconductors

Ama-semiconductors yizinto ezibonisa izakhiwo phakathi kwama-conductor nama-insulators. Bangakwazi ukuhambisa ugesi ngaphansi kwezimo ezithile, okubenza balungele ukulawula imisinga kagesi kumadivayisi. Izinto ezijwayelekile ze-semiconductor zifaka:

• • I-silicon (Si): Izinto ezisetshenziswa kakhulu ze-semiconductor ngenxa yobuningi bayo kanye nezakhiwo zikagesi ezinhle kakhulu.
  • I-Germany (Ge): Yaziwa ngokusebenza kwayo okuphezulu kwe-thermal, evame ukuhlanganiswa ne-silicon ukuze isebenze kangcono.
  • I-Gallium Arsenide (GaAs): Isetshenziswa kuzinhlelo zokusebenza ezinesivinini esikhulu kanye nemvamisa ephezulu, yize ibiza kakhulu kune-silicon.

Iqhaza le-Semiconductor PCBs

Ngenkathi ama-semiconductors ephatha ukucutshungulwa nokulawula amasignali kagesi, ama-PCB we-Semiconductor ahlinzeka ngosekelo oludingekayo kanye nokuxhumana. Baqinisekisa ukuthi amadivaysi e-semiconductor agxunyekwe ngokuphephile, axhumeke kahle, futhi alawulwa ngokuphumelelayo ngokuya ngokuchithwa kwe-thermal nobuqotho besignali.
