Foyilo yamkuwa ya PCB

Chifukwa cha kuchuluka kwa kugwiritsa ntchito zipangizo zamagetsi, kufunikira kwa zipangizozi kwakhala kwakukulu pamsika nthawi zonse. Zipangizozi pakadali pano zimatizungulira chifukwa timadalira kwambiri pazifukwa zosiyanasiyana. Pachifukwa ichi, ndikutsimikiza kuti mwakumana ndi chipangizo chamagetsi kapena nthawi zambiri mumagwiritsa ntchito kunyumba. Ngati mugwiritsa ntchito zipangizozi, mungadabwe momwe zida zamagetsi zimalumikizirana, momwe zimagwirira ntchito, komanso momwe chipangizocho chingalumikizidwire ndi zinthu zina. Zipangizo zamagetsi zomwe timagwiritsa ntchito kunyumba zimapangidwa ndi zipangizo zomwe sizimayendetsa magetsi. Zili ndi njira zojambulidwa ndi zinthu zamkuwa zomwe zimayendetsa magetsi pamwamba pake, zomwe zimathandiza kuti chizindikirocho chiziyenda mkati mwa chipangizocho chikagwira ntchito.

Chifukwa chake, ukadaulo wa PCB umachokera pa kumvetsetsa momwe zipangizo zamagetsi zimagwirira ntchito. PCB nthawi zonse imagwiritsidwa ntchito kwambiri mu zipangizo zamagetsi zomwe zimapangidwira zoulutsira nkhani. Komabe, m'mibadwo yamakono, zimagwiritsidwa ntchito mu zipangizo zonse zamagetsi. Pachifukwa ichi, palibe chipangizo chamagetsi chomwe chingagwire ntchito popanda PCB. Blog iyi ikuyang'ana kwambiri pa pepala lamkuwa la PCB, ndi ntchito yomwe imachitika ndipepala la mkuwamu makampani a circuit board.

Ukadaulo wa Printed Circuit Board (PCB)

Ma PCB ndi njira zomwe zimayendetsa magetsi monga mizere ndi njira, zomwe zimapakidwa ndi foil yamkuwa. Izi zimapangitsa kuti zilumikizane ndikuthandizira zida zina zamagetsi zolumikizidwa ndi makina ku chipangizocho. Pachifukwa ichi, ntchito yayikulu ya ma PCB awa muzipangizo zamagetsi ndikupereka chithandizo kunjirazo. Nthawi zambiri, zipangizo monga fiberglass ndi pulasitiki zimasunga mosavuta foil yamkuwa mu dera. Foil yamkuwa mu PCB nthawi zambiri imapakidwa ndi substrate yosayendetsa magetsi. Mu PCB, foil yamkuwa imagwira ntchito yofunika kwambiri polola kuyenda kwa magetsi pakati pa zigawo zosiyanasiyana za chipangizocho, potero imathandizira kulumikizana kwawo.

Asilikali nthawi zonse amalumikizana bwino pakati pa pamwamba pa PCB ndi zida zamagetsi. Zosungunula izi zimapangidwa pogwiritsa ntchito chitsulo chomwe chimapangitsa kuti zikhale zomatira zolimba; motero, ndizodalirika popereka chithandizo chamakina ku zigawo zake. Njira ya PCB nthawi zambiri imapangidwa ndi zinthu zosiyanasiyana monga silkscreen ndi zitsulo zolumikizidwa ndi substrate kuti zikhale PCB.

Udindo wa zojambulazo zamkuwa mumakampani opanga ma circuit board

Ukadaulo watsopano womwe ukupitilira masiku ano ukutanthauza kuti palibe chipangizo chamagetsi chomwe chingagwire ntchito popanda PCB. Koma PCB imadalira kwambiri mkuwa kuposa zigawo zina. Izi zili choncho chifukwa mkuwa umathandiza kupanga zizindikiro zomwe zimalumikiza zigawo zonse mu PCB kuti zilole kuti mphamvu iyende bwino mkati mwa chipangizocho. Zizindikirozo zitha kufotokozedwa ngati mitsempha yamagazi m'chimake cha PCB. Chifukwa chake PCB singathe kugwira ntchito zizindikirozo zikasowa. PCB ikalephera kugwira ntchito, chipangizo chamagetsi chimataya lingaliro lake, zomwe zimapangitsa kuti chisagwire ntchito. Chifukwa chake, mkuwa ndiye gawo lalikulu la PCB. Chojambula cha mkuwa mu PCB chimatsimikizira kuti zizindikiro ziziyenda nthawi zonse popanda kusokoneza.

Zinthu zamkuwa nthawi zonse zimadziwika kuti zimakhala ndi mphamvu yoyendetsa bwino kuposa zinthu zina chifukwa cha ma elekitironi aulere omwe ali mu chipolopolo chake. Ma elekitironiwo amatha kuyenda popanda kukana atomu iliyonse yomwe imapangitsa mkuwa kukhala wokhoza kunyamula magetsi oyenda bwino popanda kutayika kapena kusokonezedwa ndi zizindikiro. Mkuwa, womwe umapanga electrolyte yoyipa, nthawi zonse umagwiritsidwa ntchito mu ma PCB ngati gawo loyamba. Chifukwa mkuwa sukhudzidwa kwambiri ndi mpweya wa pamwamba, ungagwiritsidwe ntchito ndi mitundu ingapo ya zinthu, zinthu zotetezera kutentha, ndi zitsulo. Ukagwiritsidwa ntchito ndi zinthu izi, umapanga mapangidwe osiyanasiyana mu dera, makamaka pambuyo pocheka. Izi nthawi zonse zimatheka chifukwa cha kuthekera kwa mkuwa kupanga mgwirizano wangwiro ndi zinthu zotetezera kutentha zomwe zimagwiritsidwa ntchito popanga PCB.

Kawirikawiri pamakhala zigawo zisanu ndi chimodzi za PCB zomwe zimapangidwa, zomwe zigawo zinayi zimakhala mu PCB. Zigawo zina ziwiri nthawi zambiri zimawonjezeredwa ku gulu lamkati. Pachifukwa ichi, zigawo ziwirizi ndi zogwiritsidwa ntchito mkati, palinso ziwiri zogwiritsidwa ntchito kunja, ndipo pomaliza, zigawo ziwiri zotsalazo mwa zisanu ndi chimodzi zonse ndi zokongoletsa mapanelo mkati mwa PCB.

Mapeto

Foyilo yamkuwandi gawo lofunika kwambiri la PCB lomwe limalola kuti magetsi aziyenda bwino popanda kusokoneza. Lili ndi mphamvu yoyendetsa bwino magetsi ndipo limapanga mgwirizano wolimba ndi zinthu zosiyanasiyana zotetezera kutentha zomwe zimagwiritsidwa ntchito mu PCB circuit board. Pachifukwa ichi, PCB imadalira zojambulazo zamkuwa kuti zigwire ntchito chifukwa zimapangitsa kuti kulumikizana kwa mafupa a PCB kugwire ntchito bwino.
