ThePCB redunhu bhodhiinogara ichichinja nekufambira mberi kweiyo tekinoroji tekinoroji, asi musimboti, yakazara PCB redunhu bhodhi inoda kudhinda bhodhi redunhu, wobva wacheka bhodhi redunhu, gadzira mhangura yakavharwa laminate, kuendesa redunhu bhodhi, Corrosion, kuchera, pretreatment, uye welding inogona chete kugoneswa mushure meaya maitiro ekugadzira.Izvi zvinotevera kunzwisiswa kwakadzama kwePCB redunhu bhodhi kugadzira maitiro.
Gadzira dhiyabhorosi dhizaini zvinoenderana nedunhu basa rinodiwa.Iyo dhizaini yedhizaini dhizaini inonyanya kuenderana nekushanda kwemagetsi kwechikamu chimwe nechimwe kuti ivakwe zvine musoro sezvinodiwa.Dhiagiramu inogona kunyatsoratidza mabasa akakosha ePCB redunhu bhodhi uye hukama pakati pezvikamu zvakasiyana.Dhizaini yedhizaini dhizaini inhanho yekutanga muPCB kugadzira maitiro, uye zvakare inhanho yakakosha.Kazhinji software inoshandiswa kugadzira dhizaini schematics ndeye PROTEl.
Mushure mekunge dhizaini yapera, zvinodikanwa kuti uwedzere kurongedza chikamu chimwe nechimwe kuburikidza nePROTEL kugadzira uye kuona grid ine chitarisiko chakafanana uye saizi yezvikamu.Mushure mekugadzirisa chikamu pasuru, ita Rongedza/Seta Zvaunoda/pini 1 kuseta iyo pasuru yekunongedza papini yekutanga.Wobva waita Report/Component Rule tarisa kuti uise mitemo yese kuti itariswe, uye OK.Panguva ino, iyo package inotangwa.
Gadzira iyo PCB zviri pamutemo.Mushure mekunge network yagadzirwa, chinzvimbo chechikamu chimwe nechimwe chinoda kuiswa zvinoenderana nehukuru hwePCB pani, uye zvinodikanwa kuve nechokwadi kuti zvinotungamira zvechikamu chimwe nechimwe hazviyambuki pakuisa.Mushure mekuiswa kwezvikamu kwapera, kuongororwa kweDRC kunozoitwa kubvisa pini kana kutungamira kukanganisa kwechikamu chimwe nechimwe panguva yewaya.Kana zvikanganiso zvese zvabviswa, yakakwana pcb dhizaini dhizaini inopedzwa.
Dhinda bhodhi redunhu: Dhinda bhodhi redunhu rakadhonzwa nebepa rekufambisa, teerera kune inotsvedza yakatarisana newe, kazhinji dhinda mapuranga maviri edunhu, ndiko kuti, dhinda mapuranga maviri edunhu pabepa rimwe.Pakati pavo, sarudza iyo ine yakanakisa kudhinda maitiro kuita bhodhi redunhu.
Cheka iyo copper clad laminate, uye shandisa iyo photosensitive ndiro kugadzira iyo yese dhizaini yedhizaini redunhu.Copper-clad laminates, kureva, mapuranga edunhu akafukidzwa nefirimu yemhangura kumativi ose maviri, akacheka mhangura-akapfeka laminates muhukuru hwebhodhi redunhu, kwete yakakura zvikuru, kuchengetedza zvinhu.
Preatment of copper clad laminates: shandisa yakanaka sandpaper kupukuta oxide layer pamusoro pemhangura yakapfeka laminates kuti uone kuti toner iri pabepa rekutamisa rinopisa rinogona kudhindwa zvakasimba pamhangura yakapfeka laminates paunenge uchiendesa bhodhi redunhu.Shiny kupera pasina mavara anooneka.
Shandura yakadhindwa redunhu bhodhi: Cheka iyo yakadhindwa yedunhu bhodhi kuita saizi yakakodzera, isa rakadhindwa redunhu bhodhi parutivi pamhangura yakashongedzwa laminate, mushure mekurongeka, isa iyo yemhangura yakashongedzwa laminate mumuchina wekutamisa wekupisa, uye simbisa kuchinjisa kana uchiisa muPepa. haina kurongeka.Kazhinji, mushure mekutamisa 2-3, bhodhi redunhu rinogona kutamirwa zvakasimba kune copper clad laminate.Muchina wekufambisa wekupisa wakafanopiswa, uye tembiricha inoiswa pa160-200 degrees Celsius.Nekuda kwekushisa kwakanyanya, ndapota teerera kune chengetedzo paunenge uchishanda!
Corrosion circuit board, reflow soldering machine: tanga kutarisa kana kuendeswa kwapera pabhodhi redunhu, kana pane nzvimbo shomanana dzisina kutamiswa zvakanaka, unogona kushandisa peni yakasviba-based peni kugadzirisa.Ipapo inogona kuve yakasvibiswa.Kana iyo firimu yemhangura yakafumurwa pabhodhi redunhu yakasvibiswa zvachose, bhodhi redunhu rinotorwa kubva mumvura inoparadza uye rinocheneswa, kuitira kuti bhodhi redunhu riparadzwe.Kuumbwa kwechigadziriso chinopisa chinogadziriswa hydrochloric acid, yakanyanyisa hydrogen peroxide, uye mvura muchiyero che1: 2: 3.Paunenge uchigadzira mushonga unoparadza, wedzera mvura kutanga, wobva wawedzera concentrated hydrochloric acid uye concentrated hydrogen peroxide.Kana iyo concentrated hydrochloric acid, concentrated hydrogen peroxide kana corrosive solution isingaiti Ngwarira kumwaya paganda kana zvipfeko woigeza nemvura yakachena nenguva.Sezvo mushonga wakasimba wekuora uchishandiswa, iva nechokwadi chekuteerera kuchengetedzwa kana uchishanda!
Circuit board drilling: Bhodhi redunhu nderekuisa zvinhu zvemagetsi, saka zvakakosha kudhiza bhodhi redunhu.Sarudza madhiri akasiyana zvichienderana nehupamhi hwepini yezvigadzirwa zvemagetsi.Paunenge uchishandisa chibooreso chekuboora makomba, bhodhi redunhu rinofanira kudzvanywa zvakasimba.Iko kumhanya kwechibooreso hakufanirwe kunge kuchinonoka.Ndapota nyatsotarisa mushandisi.
Circuit board pretreatment: Mushure mekuchera, shandisa sandpaper yakanaka kupuruzira kubva kune toner yakavhara bhodhi redunhu, uye chenesa bhodhi redunhu nemvura yakachena.Mushure mokunge mvura yaoma, shandisa mvura yepine kudivi nedunhu.Kuti tikurumidze kusimba kwe rosin, tinoshandisa mhepo inopisa inopisa kupisa bhodhi redunhu, uye rosin inogona kusimba mumaminitsi 2-3 chete.
Welding electronic components: Mushure mekunge basa rekushongedza rapera, ita bvunzo yakazara pabhodhi rese redunhu.Kana pane dambudziko panguva yekuedzwa, zvinodikanwa kuti uone nzvimbo yedambudziko kuburikidza nedhiyabhorosi dhizaini yakagadzirwa mudanho rekutanga, uye wozotengesazve kana kutsiva chikamu.mudziyo.Kana bvunzo yapasa zvinobudirira, bhodhi rese redunhu rinopera.
