Chojambula chamkuwa cha PCB

Chifukwa cha kuchuluka kwa zida zamagetsi, kufunikira kwa zida izi kwakhala kwakukulu pamsika. Zidazi zatizungulira pano chifukwa timadalira kwambiri pazifukwa zosiyanasiyana. Pazifukwa izi, ndikubetcha kuti mwapeza chipangizo chamagetsi kapena nthawi zambiri mumachigwiritsa ntchito kunyumba. Ngati mumagwiritsa ntchito zipangizozi, mungadabwe kuti zida zamagetsi zimalumikizidwa bwanji ndi mawaya, momwe zimagwirira ntchito, komanso momwe chipangizocho chingagwirizane ndi zinthu zina. Zida zamagetsi zomwe timagwiritsa ntchito kunyumba zimapangidwa ndi zinthu zomwe sizimayendetsa magetsi. Iwo ali ndi njira zokhazikika ndi zinthu zamkuwa zomwe zimayendetsa pamwamba pawo, zomwe zimalola kuti chizindikirocho chiziyenda mkati mwa chipangizocho chikugwira ntchito.

Choncho, luso la PCB zachokera kumvetsa ntchito zipangizo zamagetsi. PCB nthawi zonse imagwiritsidwa ntchito kwambiri pazida zamagetsi zopangidwira media. Komabe, m'zaka zamakono, zimagwiritsidwa ntchito pazida zonse zamagetsi. Pachifukwa ichi, palibe chipangizo chamagetsi chomwe chingagwire ntchito popanda PCB. Blog iyi imayang'ana kwambiri zojambula zamkuwa za PCB, ndi gawo lomwe azojambula zamkuwam'makampani opanga ma circuit board.

The Printed Circuit Board (PCB) Technology

Ma PCB ndi njira zomwe zimayendera magetsi monga ma trace ndi ma track, omwe amapangidwa ndi zojambulazo zamkuwa. Izi zimawapangitsa kuti azilumikizana ndikuthandizira zida zina zamagetsi zomwe zimalumikizidwa ndi chipangizocho. Pachifukwa ichi, ntchito yaikulu ya ma PCB awa pazida zamagetsi ndikupereka chithandizo kunjira. Nthawi zambiri, zida monga magalasi a fiberglass ndi mapulasitiki amatha kugwira zojambula zamkuwa pozungulira. Chojambula chamkuwa mu PCB nthawi zambiri chimakhala laminated ndi gawo lapansi lopanda conductive. Mu PCB, zojambulazo zamkuwa zimagwira ntchito yofunika kwambiri polola kuti magetsi aziyenda pakati pazigawo zosiyanasiyana za chipangizocho, potero amathandizira kulumikizana kwawo.

Asilikali nthawi zonse amalumikizana bwino pakati pa PCB pamwamba ndi zida zamagetsi. Ogulitsawa amapangidwa pogwiritsa ntchito zitsulo zomwe zimawapangitsa kukhala zomatira zolimba; choncho, ndi odalirika popereka chithandizo cha makina ku zigawo zake. Njira ya PCB nthawi zambiri imakhala ndi composted ndi zigawo zambiri za zinthu zosiyanasiyana monga silkscreen ndi zitsulo zopangidwa ndi gawo lapansi kuti zikhale PCB.

Udindo wa zojambula zamkuwa mumakampani opanga ma boardboard

Zamakono zamakono zomwe zikuchitika masiku ano zikutanthauza kuti palibe chipangizo chamagetsi chomwe chingagwire ntchito popanda PCB. PCB, kumbali ina, imadalira kwambiri mkuwa kuposa zigawo zina. Izi ndichifukwa choti mkuwa umathandizira kupanga zidziwitso zomwe zimalumikizana ndi zigawo zonse za PCB kuti zilole kuthamanga kwamagetsi mkati mwa chipangizocho. Zotsatirazi zitha kufotokozedwa ngati mitsempha yamagazi yomwe ili m'mafupa a PCB. Choncho PCB sangathe kugwira ntchito pamene kuda akusowa. PCB ikalephera kugwira ntchito, chipangizo chamagetsi chidzataya lingaliro lake, ndikuchipanga kukhala chopanda ntchito. Choncho, mkuwa ndiye chigawo chachikulu cha madulidwe a PCB. Chojambula chamkuwa mu PCB chimatsimikizira kuyenda kosalekeza kwa zizindikiro popanda kusokoneza.

Zinthu zamkuwa nthawi zonse zimadziwika kuti zimakhala ndi ma conductivity apamwamba kuposa zipangizo zina chifukwa cha ma electron aulere omwe amapezeka mu chipolopolo chake. Ma electron ndi omasuka kusuntha popanda kutsutsa atomu iliyonse yomwe imapanga mkuwa wokhoza kunyamula magetsi oyenda bwino popanda kutaya kapena kusokonezedwa ndi zizindikiro. Mkuwa, womwe umapanga electrolyte yabwino kwambiri, umagwiritsidwa ntchito nthawi zonse mu ma PCB ngati gawo loyamba. Chifukwa mkuwa sukhudzidwa kwambiri ndi okosijeni wa pamwamba, ukhoza kugwiritsidwa ntchito ndi mitundu ingapo ya magawo, magawo oteteza, ndi zitsulo. Ikagwiritsidwa ntchito ndi magawo awa, imapanga machitidwe osiyanasiyana ozungulira, makamaka pambuyo pa etching. Izi nthawi zonse zimatheka chifukwa cha kuthekera kwa mkuwa kupanga mgwirizano wangwiro ndi zigawo zoteteza zomwe zimagwiritsidwa ntchito popanga PCB.

Nthawi zambiri pamakhala zigawo zisanu ndi chimodzi za PCB zomwe zimapangidwa, zomwe zigawo zinayi zili mu PCB. Zigawo zina ziwiri nthawi zambiri zimawonjezeredwa ku gulu lamkati. Pachifukwa ichi, zigawo ziwirizi ndizogwiritsidwa ntchito mkati, palinso ziwiri zogwiritsira ntchito kunja, ndipo potsiriza, awiri otsala mwa zigawo zisanu ndi chimodzi ndizowonjezera mapanelo mkati mwa PCB.

Mapeto

Chojambula chamkuwandi gawo lofunikira la PCB lomwe limalola kuyenda kwa magetsi amagetsi popanda kusokonezedwa. Iwo ali madutsidwe mkulu ndipo mwangwiro amapanga chomangira amphamvu ndi zipangizo zosiyanasiyana insulating ntchito PCB dera bolodi. Pazifukwa izi, PCB imadalira zojambulazo zamkuwa kuti zigwire ntchito chifukwa zimapangitsa kulumikizana kwa mafupa a PCB kukhala kothandiza.
