A. icyapa cyumuzunguruko (PCB) ni ikibaho cyoroshye gikozwe muri fiberglass, epoxy composite, cyangwa ibindi bikoresho bya laminate.PCB iboneka mubice bitandukanye byamashanyarazi na elegitoronike nka beepers, amaradiyo, radar, sisitemu ya mudasobwa, nibindi. Ubwoko butandukanye bwa PCB bukoreshwa bushingiye kubisabwa.Ni ubuhe bwoko butandukanye bwa PCB?Soma kugirango umenye.

Ni ubuhe bwoko butandukanye bwa PCB?

PCB ikunze gushyirwa mubikorwa hashingiwe kuri frequency, umubare wibice hamwe na substrate ikoreshwa.Ubwoko bumwe buzwi bwaganiriweho hepfo.

• PCBs imwe
  PCBs kuruhande rumwe nubwoko bwibanze bwibibaho byumuzunguruko, birimo igice kimwe gusa cya substrate cyangwa ibikoresho fatizo.Igice gitwikiriwe nicyuma cyoroshye, ni ukuvuga umuringa- ni umuyoboro mwiza w'amashanyarazi.Izi PCB zirimo kandi mask yo kugurisha irinda, ikoreshwa hejuru yumuringa hamwe na kote ya silike.Inyungu zimwe zitangwa na PCB kuruhande rumwe ni:
  • PCB uruhande rumwe rukoreshwa mugutanga umusaruro kandi ni bike mubiciro.
  • Izi PCB zikoreshwa mumuzunguruko woroshye nka sensor ya power, relay, sensor hamwe nudukinisho twa elegitoronike.
• PCB ebyiri
  Impande ebyiri PCBs zifite impande zombi za substrate zirimo ibyuma bitwara ibyuma.Imyobo mu kibaho cyizunguruka yemerera ibice byicyuma guhuzwa kuva kuruhande rumwe.Izi PCB zihuza imirongo kumpande zombi haba muri gahunda ebyiri zo kwishyiriraho, arizo binyuze mu mwobo wa tekinoroji hamwe na tekinoroji yo hejuru.Ikoranabuhanga ryanyuze mu mwobo ririmo kwinjiza ibice byayoboye binyuze mu mwobo wabanje gucukurwa ku kibaho cy’umuzunguruko, bigurishwa ku makarito ku mpande zinyuranye.Ubuso bwa tekinoroji yubuso burimo ibice byamashanyarazi bigomba gushyirwa kumurongo wibibaho byumuzunguruko.Inyungu zitangwa na PCB zibiri ni:
  • Kwishyiriraho hejuru bituma imiyoboro myinshi ihambira ku kibaho ugereranije no kunyura mu mwobo.
  • Izi PCB zikoreshwa muburyo butandukanye bwa porogaramu, zirimo sisitemu ya terefone igendanwa, gukurikirana ingufu, ibikoresho byo gupima, amplifier, n'ibindi byinshi.
• PCB nyinshi
  PCBs nyinshi zicapishijwe imbaho ​​zumuzunguruko, zigizwe nimirongo irenga ibiri yumuringa nka 4L, 6L, 8L, nibindi. Izi PCB zagura ikoranabuhanga rikoreshwa muri PCB zombi.Ibice bitandukanye byububiko bwa substrate hamwe nibikoresho byo gutandukanya bitandukanya ibice muri PCB nyinshi.PCBs nini nini, kandi itanga inyungu zuburemere n'umwanya.Inyungu zimwe zitangwa na PCBs nyinshi:
  • PCBs nyinshi zitanga urwego rwohejuru rwo gushushanya.
  • Izi PCB zifite uruhare runini mukuzunguruka kwihuta.Batanga umwanya munini kubayobora nimbaraga.
• PCBs
  PCBs zikomeye zivuga kuri ubwo bwoko bwa PCB ibikoresho fatizo byahimbwe mubintu bikomeye kandi bidashobora kugororwa.Inyungu zingenzi zitangwa nabo:
  • Izi PCB zirahuzagurika, zituma habaho uburyo butandukanye bwumuzunguruko uzengurutse.
  • PCB zikomeye zitanga gusana no kubungabunga byoroshye, nkuko ibice byose byerekanwe neza.Na none, inzira yerekana ibimenyetso itunganijwe neza.
• PCB zoroshye
  PCB zoroshye zubatswe kubintu byoroshye.Izi PCB ziza muburyo bumwe, impande ebyiri kandi nyinshi.Ibi bifasha mukugabanya ibintu bigoye mubiterane byibikoresho.Inyungu zimwe zitangwa nizi PCBs ni:
  • Izi PCB zifasha kuzigama umwanya munini, hamwe no kugabanya uburemere bwibibaho.
  • PCBs ihindagurika ifasha mukugabanya ingano yubuyobozi, ibyo bikaba byiza kubikorwa bitandukanye aho bikenewe ibimenyetso byerekana ibimenyetso byinshi.
  • Izi PCB zagenewe akazi, aho ubushyuhe nubucucike aribibazo byingenzi.
• Rigid-Flex-PCBs
  Rigid flex PCBs ni ihuriro ryibibaho byumuzingi kandi byoroshye.Zigizwe nibice byinshi byumuzunguruko woroshye uhujwe kurenza ikibaho gikomeye.
  • Izi PCBs zubatswe neza.Kubwibyo, ikoreshwa mubikorwa bitandukanye byubuvuzi nigisirikare.
  • Kuba ufite uburemere bworoshye, izi PCB zitanga 60% yuburemere no kuzigama umwanya.
• PCBs nyinshi
  PCBs yihuta cyane ikoreshwa murwego rwa 500MHz - 2GHz.Izi PCB zikoreshwa mubikorwa bitandukanye byingirakamaro nka sisitemu yitumanaho, microwave PCBs, microstrip PCBs, nibindi.
• Aluminium yashyigikiye PCB
  Izi PCB zikoreshwa mumashanyarazi menshi, nkuko kubaka aluminiyumu bifasha mukwirakwiza ubushyuhe.Aluminium ishyigikiwe na PCB izwiho gutanga urwego rwo hejuru rwo gukomera no kurwego rwo hasi rwo kwagura ubushyuhe, ibyo bikaba byiza kubisabwa bifite kwihanganira imashini.PCBs zikoreshwa kuri LED no gutanga amashanyarazi.

Isabwa rya PCB riragenda ryiyongera mu nzego zitandukanye zinganda.Uyu munsi, uzasangamo ibintu bitandukanye abakora PCB bazwi n'ababitanga, batanga isoko ryo guhuza ibikoresho isoko.Buri gihe birasabwa kugura PCB kugirango ikoreshwe mu nganda n’ubucuruzi mu nganda zizwi n’abatanga ibicuruzwa.Twisted Traces nimwe mubikorwa byizewe kandi bifite uburambe muburyo butandukanye bwa PCB.Isosiyete yagiye iha abakiriya bayo imbaho ​​nziza zumuzunguruko zifite umuvuduko mwiza, nibikorwa.
