A ibhodi lesifunda eliphrintiwe (PCB) ibhodi elincanyana elenziwe nge-fiberglass, i-epoxy eyinhlanganisela, noma ezinye izinto ezilayiniwe.Ama-PCB atholakala ezingxenyeni ezihlukene zikagesi neze-elekthronikhi ezifana nama-beepers, imisakazo, ama-radar, amasistimu wekhompyutha, njll. Izinhlobo ezahlukene zama-PCB zisetshenziswa ngokusekelwe kuzinhlelo zokusebenza.Yiziphi izinhlobo ezahlukene zama-PCB?Funda ukuze wazi.

Yiziphi Izinhlobo Ezihlukene zama-PCB?

Ama-PCB avame ukuhlukaniswa ngesisekelo semvamisa, inani lezendlalelo ne-substrate esetshenziswa.Ezinye izinhlobo ezidumile kuxoxwa ngazo ngezansi.

• Ama-PCB Asemaceleni Awodwa
  Ama-PCB anohlangothi olulodwa ziwuhlobo oluyisisekelo lwamabhodi wesifunda, aqukethe ungqimba olulodwa kuphela lwe-substrate noma impahla eyisisekelo.Ungqimba lumbozwe ungqimba oluncane lwensimbi, okungukuthi ithusi- okuwumqhubi omuhle kagesi.Lawa ma-PCB futhi aqukethe imaski ye-solder evikelayo, esetshenziswa phezulu kongqimba lwethusi kanye nejazi lesikrini sikasilika.Ezinye izinzuzo ezinikezwa ama-PCB anohlangothi olulodwa yilezi:
  • Ama-PCB anohlangothi olulodwa asetshenziselwa ukukhiqizwa kwevolumu futhi anezindleko eziphansi.
  • Lawa ma-PCB asetshenziselwa amasekhethi alula njengezinzwa zamandla, ama-relay, izinzwa namathoyizi kagesi.
• Ama-PCB anezinhlangothi ezimbili
  Ama-PCB anezinhlangothi ezimbili anazo zombili izinhlangothi ze-substrate ene-metal conductive layer.Izimbobo ebhodini lesifunda zivumela izingxenye zensimbi ukuba zihlanganiswe ukusuka kolunye uhlangothi kuya kolunye.Lawa ma-PCB axhuma amasekhethi nhlangothi zombili nganoma yiliphi kwezikimu ezimbili zokukhweza, okuwubuchwepheshe be- through-hole kanye nobuchwepheshe bokukhweza phezulu.Ubuchwepheshe be- through-hole buhilela ukufakwa kwezingxenye zomthofu ngokusebenzisa izimbobo ezimbozwe ngaphambili ebhodini lesifunda, ezidayiswa kumaphedi ezinhlangothini eziphambene.Ubuchwepheshe be-surface mount buhilela izingxenye zikagesi ukuze zibekwe ngokuqondile ebusweni bamabhodi wesifunda.Izinzuzo ezinikezwa ama-PCB anezinhlangothi ezimbili yilezi:
  • Ukukhweza phezulu kuvumela amasekhethi engeziwe ukuthi anamathiselwe ebhodini uma kuqhathaniswa nokukhwezwa kwembobo ephumela.
  • Lawa ma-PCB asetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, okuhlanganisa isistimu yomakhalekhukhwini, ukuqapha amandla, okokusebenza kokuhlola, izikhulisamazwi, nokunye okuningi.
• Ama-PCB anezingqimba eziningi
  Ama-PCB anezingqimba eziningi amabhodi esekethe aphrintiwe, ahlanganisa izendlalelo zethusi ezingaphezu kwezimbili njenge-4L, 6L, 8L, njll. Lawa ma-PCB andisa ubuchwepheshe obusetshenziswa kuma-PCB anezinhlangothi ezimbili.Izendlalelo ezahlukahlukene zebhodi elingaphansi nezinto zokuvikela zihlukanisa izingqimba kuma-PCB anezingqimba eziningi.Ama-PCB anosayizi ohlangene, futhi anikeza izinzuzo zesisindo nesikhala.Ezinye izinzuzo ezinikezwa ama-PCB anezingqimba eziningi yilezi:
  • Ama-PCB anezingqimba eziningi anikeza izinga eliphezulu lokuguquguquka komklamo.
  • Lawa ma-PCB adlala indima ebalulekile kumasekhethi anesivinini esikhulu.Banikeza isikhala esengeziwe sephethini yomqhubi namandla.
• Ama-PCB aqinile
  Ama-PCB aqinile abhekisa kulezo zinhlobo zama-PCB asisekelo sazo senziwe ngezinto eziqinile futhi ezingakwazi ukugoba.Ezinye izinzuzo ezibalulekile ezinikezwa yibo:
  • Lawa ma-PCB ahlangene, okuqinisekisa ukudalwa kwezinhlobonhlobo zezifunda eziyinkimbinkimbi ezizungezile.
  • Ama-PCB aqinile anikeza ukukhanda nokugcinwa kalula, njengoba zonke izingxenye zimakwe ngokucacile.Futhi, izindlela zesignali zihlelwe kahle.
• Ama-PCB aguquguqukayo
  Ama-PCB aguquguqukayo zakhiwe phezu kwesisekelo esivumelana nezimo.Lawa ma-PCB eza ngamafomethi anohlangothi olulodwa, anezinhlangothi ezimbili kanye nezakhiwo eziningi.Lokhu kusiza ekwehliseni ubunkimbinkimbi ngaphakathi komhlangano wedivayisi.Ezinye izinzuzo ezinikezwa yilawa ma-PCB yilezi:
  • Lawa ma-PCB asiza ukonga isikhala esiningi, kanye nokunciphisa isisindo sebhodi sisonke.
  • Ama-PCB aguqukayo asiza ekwehliseni usayizi webhodi, okulenza lilungele izinhlelo zokusebenza ezahlukahlukene lapho kudingeka khona ukuminyana kwesignali ephezulu.
  • Lawa ma-PCB enzelwe izimo zokusebenza, lapho izinga lokushisa nokuminyana kuyinto ekhathaza kakhulu.
• I-Rigid-Flex-PCBs
  Ama-PCB aguquguqukayo aqinile ziyinhlanganisela yamabhodi wesifunda aqinile futhi aguquguqukayo.Ahlanganisa izendlalelo eziningi zamasekhethi aguquguqukayo anamathiselwe ebhodini eliqinile elingaphezu kwelilodwa.
  • Lawa ma-PCB akhiwe ngokunemba.Ngakho-ke, isetshenziswa ezinhlobonhlobo zezokwelapha nezempi.
  • Njengoba zinesisindo esincane, lezi PCB zinikeza u-60% wesisindo nokonga isikhala.
• High-Frequency PCBs
  Ama-PCB anemvamisa ephezulu asetshenziswa ebangeni lemvamisa lika-500MHz - 2GHz.Lawa ma-PCB asetshenziswa ezinhlelweni ezahlukahlukene ezibucayi njengezinhlelo zokuxhumana, ama-microwave PCB, ama-microstrip PCB, njll.
• Ama-PCB asekelwa yi-aluminium
  Lawa ma-PCB asetshenziswa ezinhlelweni zamandla aphezulu, njengoba ukwakhiwa kwe-aluminium kusiza ekuqedeni ukushisa.Ama-PCB asekelwa i-aluminium aziwa ngokunikeza izinga eliphezulu lokuqina kanye nezinga eliphansi lokunwetshwa okushisayo, okuwenza alungele izinhlelo zokusebenza ezinokubekezelela okuphezulu kwemishini.Ama-PCB asetshenziselwa ama-LED nezinto zikagesi.

Isidingo sama-PCB siyakhula emikhakheni eyahlukene yezimboni.Namuhla, uzothola ezihlukahlukene abakhiqizi be-PCB abahlonishwayo nabasabalalisi, ababhekelela imakethe yamadivayisi axhumeneyo aqhudelanayo.Kuhlale kunconywa ukuthenga ama-PCB ukuze asetshenziswe ezimbonini nezokuhweba kubakhiqizi nabahlinzeki abahlonishwayo.I-Twisted Traces ingomunye wabakhiqizi abathembekile nabanolwazi lwezinhlobo ezahlukene zama-PCB.Le nkampani ibilokhu ihlinzeka amakhasimende abo ngamabhodi esekethe ekhwalithi ephezulu anesivinini esihle kakhulu, nokusebenza.
