PCB Gungano: Mwoyo Wemagetsi Zvishandiso
Yakadhindwa Circuit Board (PCB) musangano inzira yekugadzira michina yemagetsi nekuisa zvinhu zvemagetsi pabhodhi nekuzvitengesa panzvimbo.Iyo PCB gungano maitiro akakosha pakushanda kwemidziyo yemagetsi, kubva kumafoni kusvika kumidziyo yekurapa, uye inhanho yakawanda-nhanho inosanganisira akati wandei matanho akakosha.
Kugadzira iyo PCB
Nhanho yekutanga muPCB gungano rekugadzira kugadzira bhodhi redunhu pacharo.Izvi zvinosanganisira kugadzira schematic inoratidza kuti zvese zvezvikamu zvichabatanidzwa sei uye kugadzira marongerwo anotsanangura kuiswa kwemuviri kwezvikamu pabhodhi.Iyo yakagadzirwa inofanira kufunga nezvehukuru uye chimiro chezvikamu, zvinodiwa nemagetsi zvedunhu, uye nzira yekugadzira iyo ichashandiswa kuunganidza bhodhi.
Kutsvaga the Components
Kana iyo PCB dhizaini yapera, danho rinotevera nderekutsvaga zvikamu izvo zvichashandiswa mukuita gungano.Izvi zvinosanganisira ese ari maviri maficha anoshanda, senge microprocessors uye memory machipi, uye passive zvikamu, senge resistors uye capacitors.Zvikamu zvinogona kuwanikwa kubva kune vakasiyana vatengesi, kusanganisira vanogadzira zvinhu, vanogovera, uye misika yepamhepo.
Kugadzirira PCB Nhanho inotevera muPCB gungano maitiro ndeyekugadzirira bhodhi rekuiswa kwechikamu.Izvi zvinosanganisira kuchenesa bhodhi kuti ubvise chero tsvina uye kushandisa soldermask kuchengetedza mitsara yemhangura uye mapedhi.Bhodhi rinobva radhirwa kugadzira maburi ekuisa chikamu uye kubvumira chikamu chinotungamira kuti chitengeswe kubhodhi.
Kuisa Zvikamu
Kana PCB ichinge yagadzirwa, nhanho inotevera ndeyekuisa zvikamu pabhodhi.Izvi zvinowanzoitwa pachishandiswa pikicha-ne-nzvimbo muchina, iyo yakarongedzwa kuti iise zvikamu nemazvo uye nemazvo.Izvo zvikamu zvinoiswa pabhodhi uye zvakabatwa panzvimbo neine adhesive yenguva pfupi. 
Soldering the Components Nhanho yekupedzisira muPCB gungano rekuita ndeyekutengesa zvikamu kubhodhi.Izvi zvinowanzoitwa uchishandisa reflow oven, iyo inoshandisa kupisa kunyungudutsa solder uye kugadzira chisungo chisingaperi pakati pechikamu chinotungamira nebhodhi.Izvo zvakatengeswa zvinoongororwa kuti zvionekwe kuti zvakanamirwa zvakachengeteka uye kuti hapana chakaremara kana anomalies mukugadzirisa.
Kuedza PCB Assembly Kana chirongwa chePCB chapera, bhodhi rakaunganidzwa rinoedzwa kuti ive nechokwadi chekuti rinoshanda sezvaitarisirwa.Izvi zvinogona kusanganisira kumhanyisa nhevedzano yebvunzo dzekushanda kuona kuti zvikamu zviri kushanda nemazvo uye kuti dunhu riri kushanda sezvakarongwa.Bhodhi rinogona zvakare kuedzwa kwezvakatipoteredza, senge tembiricha uye humidity kuyedzwa, kuti ive nechokwadi chekuti ichaita nekuvimbika mumamiriro epasirese.
Mhedziso PCB gungano inhanho yakakosha mukugadzirwa kwemidziyo yemagetsi, uye maitiro anogona kuve nemhedzisiro yakakura pakuita uye kuvimbika kwechigadzirwa chakapedzwa.Kubva pakugadzira PCB kusvika kuzvinhu zvekutsvagisa, kugadzirira bhodhi, kuisa zvikamu, kutengesa, uye kuyedza, nhanho imwe neimwe yemaitiro acho inofanirwa kunyatsoitwa kuti ive nechokwadi chekuti mhedzisiro ndeyemhando yepamusoro, inoshanda mudziyo.Ungave uri mugadziri, mugadziri, kana hobbyist, kunzwisisa PCB gungano maitiro chikamu chakakosha pakugadzira zvigadzirwa zvemagetsi zvinoshanda uye kuita sezvakarongwa.
