PCB Ingqikelelo yokwenziwa: Ukwenziwa kwePCB kuqala ngePCB “substrate” eyenziwe ngeGlass Epoxy okanye izinto ezifanayo. Inyathelo lokuqala lokwenziwa kukuyila i-wiring ye-PCB ye-intanethi phakathi kwamacandelo ngokusebenzisa indlela yokudluliselwa kwe-Subtractive ukuya “kuprinta” umgca ongalunganga webhodi ye-PCB eyiliweyo kwi-conductor yesinyithi.

Ubuqhetseba kukusasaza umaleko omncinci wobhedu wobhedu ngaphezulu kobuso bonke kwaye ususe nakuphi na ukugqitha. Ukuba wenza iPCB yeepaneli ezimbini, ifoyile yobhedu iya kugubungela omabini amacala e-substrate. Kwaye ndifuna ukwenza ibhodi ye-multilayer ukuze ndikwazi ukwenza ipleyiti yobuso obuphindwe kabini ngomsonto onamathelayo “cofa ukuvala” ukunyuka kuye.

Emva koko, ukubhola kunye nesingxobo esifunekayo sokuplahla izinto kunokwenziwa kwibhodi ye-PCB. Emva kokugrunjwa ngumatshini njengoko kufuneka, imingxuma kufuneka iPlated ngaphakathi (Plated through-hole Technology, PTH). Emva kokwenza unyango lwesinyithi ngaphakathi komngxuma, imigca yangaphakathi yoluhlu ngalunye inokudityaniswa komnye nomnye.

Imingxuma kufuneka icocwe inkunkuma phambi kokuba kuqaliswe ukucwenga. Kungenxa yokuba i-resin epoxy iya kuvelisa utshintsho lweekhemikhali emva kokufudumeza, kwaye iya kugubungela ungqimba lwangaphakathi lwePCB, ke kufuneka isuswe kuqala. Ukucoca kunye nesingxobo kwenziwa kwinkqubo yemichiza. Okulandelayo, ipeyinti ye-solder (i-inki ye-solder) isetyenziswe kwi-wiremost yoyilo lwe-PCB engaphandle ukwenzela ukuba i-PCB yoyilo lwe-wiring ingachukumisi inxalenye yokucwenga.

Iileyibhile zamacandelo ahlukeneyo ziye ziprintwe kwibhodi yesekethe ukubonisa indawo yecandelo ngalinye. Akufunekanga igqunywe kuyo nayiphi na i-PCB yoyilo lweingcingo okanye umnwe wegolide, kungenjalo inokunciphisa ukuqina okanye ukuzinza koqhagamshelo lwangoku. Ukongeza, ukuba kukho uqhagamshelo lwentsimbi, icandelo “lomnwe” lihlala lifakwe igolide ukuqinisekisa unxibelelwano oluphezulu lwangoku xa ufakwa kwisakhiwo sokwandisa. Ekugqibeleni, kukho uvavanyo. Ukuvavanya i-PCB yesekethe emfutshane okanye isekethe evulekileyo, uvavanyo lwe-optical okanye lwe-elektroniki lunokusetyenziswa. Uvavanyo lwe-Optical lusebenzisa ukuskena ukufumana iziphene kumaleya, ngelixa iimvavanyo zekhompyuter zisebenzisa i-flyprobe ukukhangela lonke unxibelelwano. Uvavanyo lwe-elektroniki luchaneke ngakumbi ekufumaneni iisekethe okanye ikhefu elifutshane, kodwa uvavanyo lwamehlo lunokufumana ngokulula ngakumbi iingxaki ngezikhewu ezingachanekanga phakathi kwabaqhubi.

I-PCB substrate kakuhle, emva kokuba iqhekeza eligqityiweyo lebhodi ephambili likwi-PCB substrate isixhobo ngokwemfuno ezahlukeneyo zamacandelo amakhulu kunye amancinci – sebenzisa umatshini wokubeka we-SMT ngokuzenzekelayo kuqala i-IC chip kunye namacandelo e-SMD “welding, iplagi ye-manual abanye oomatshini benza umsebenzi, ngenkqubo yokuthengiswa kwamaza/yokuqukuqela kwakhona amacandelo e-splice amiswe ngokuqinileyo kwi-PCB, Kwaveliswa i-motherboard. Indlela yoNyango: Iklasi yoMgangatho:

I-1, ukugcinwa komgangatho: gcina umgangatho wokhuni, kufuneka ukhusele ifilimu yepeyinti yobuso bayo ngaphezu kwayo yonke into, ayinako ukulimaza “imbonakalo” yayo, nangona kunjalo, ngenxa yefilimu yepeyinti yokhuni ngalunye oluhlukeneyo, gcina indlela ngokunjalo. azifani.

Umgangatho we-Nitro we-varnish floor: sula ngokungathandekiyo ngelaphu elimanzi okanye ngamanzi, hleze uphulukane nobumnandi kunye neqokobhe. Wonke ubuxoki phakathi kwesiqingatha sonyaka okanye iinyanga ezimbalwa, xuba nge-wax ekhazimlayo besmear, phinda usebenzise i-cotton gauze ecocekileyo elandelayo. Sebenzisa itawuli ethambileyo okanye intambo yomqhaphu ngamaxesha aqhelekileyo sula uthuli kwitoti yepeyinti yepeyinti. Nika ingqalelo ukuthintela ukuvezwa kunye nomsi.

I-lacquer ebanzi kunye nomgangatho we-lacquer: awukwazi ukusula rhoqo ngamanzi acacileyo we-brush ephantsi yokushisa.

Hlanganisa ibhodi yomgangatho we-ammonia fat lacquer: Sula ngokungathandekiyo ngamanzi, hleze usule amanqatha angaphezulu kunomgangatho, kwaye unciphise ukubengezela komphezulu. I-Alcohol acerbity varnish floor: ilaphu elimanzi okanye itawuli ethambileyo ingasetyenziswa xa usebenzisa ukosula, into engathandekiyo yokudlula eshushu kolu hlobo lomgangatho, ayinakugquma umphezulu ngephepha leplastiki okanye into yohlobo lwephepha. Okwesibini, ulondolozo lomgangatho wokhuni kufuneka luqwalasele ukuthintela izixhobo ezibukhali zentsimbi, iithayile zeglasi, isikhonkwane kunye nezinye izinto ezilukhuni ezikrwela umgangatho, musa ukuhambisa ifanitshala kumgangatho womphezulu wokurhuqa intshukumo; Kuphephe ukugxotha iimpundu zecuba phantsi kwaye ubeke izinto ze-asidi kunye ne-alkali; Musa ukubeka ngqo iketile, isitovu kunye nezinye izinto zobushushu obuphezulu.

Umgangatho wokhuni emva kokusebenzisa ixesha elide, ubonakala ngathi yinto endala, kufuneka inyuke ngexesha le-lacquer. Indlela ye-Lacquer ineentlobo ezimbini: uhlobo olulodwa lokunyuka ngokuthe ngqo kwe-lacquer kunye nombala, indlela yayo kunye nefenitshala yokuchwela iyafana, umgangatho we-wax kwi-besmear emva kokulinda owomileyo, 2 kukuba awufuni nawuphi na umbala ukwenza umbala wesiseko, kufuneka kwakhona. hayi nayiphi na ipeyinti, ibhrashi nge wax umgangatho ngqo kunjalo. Ngenxa yokuba umgangatho wamaplanga luhlobo lwemathiriyeli yendalo, nxiba kakuhle hayi kuphela, kwaye usenako ukulibazisa njengoko ixesha ngosuku ngalunye oludlulayo ngokugqibeleleyo, indalo engaphezulu, ngakumbi umgangatho ococekileyo we-wax womthi, iya kuba yinto eqaqambileyo ngakumbi, egudileyo, entle.

2, ukugcinwa komgangatho we-laminate

Ukusetyenziswa komgangatho womthi we-aggrandizement ugcina ulula, ufuna ukuqaphela amanqaku alandelayo kuphela ekusebenziseni imihla ngemihla, unokuqinisekisa ukusetyenziswa okuqhelekileyo komgangatho.

(1) Yonke imigangatho eyenziwe ngomthi iyakutshintsha ukufuma kwayo ngokonyuka nokuhla kokufuma okanye utshintsho lobushushu, okuchaphazela ukwandiswa komgangatho. Isizathu kufuneka sifane ukukhusela ulusu efanayo, gcina umgangatho ukufuma efanelekileyo emgangathweni.

(2) Umgangatho ngokuqhelekileyo awufuni ukufakwa kwe-wax kunye nokupeyinta. Musa ukusebenzisa sandpaper ukupolisha.

(3) Kunconywa ukubeka i-MATS yokuxubha emnyango ukuze kuthintelwe amasuntswana othuli ukuba angangeni kwaye wonakalise umgangatho.

(4) Amabala namabala e-oyile kumphezulu womgangatho afanele acocwe ngezicoci zendlu. Musa ukusebenzisa amanzi amaninzi ukucoca umgangatho.

(5) imimandla eyomileyo esemantla, ebusika kufuneka inikele ingqalelo ekunyuseni ukufuma komgangatho womgangatho, kunye ne-mop mop efumileyo, inyuse ngokufanelekileyo ukufuma komhlaba, inokusombulula ngokufanelekileyo umsantsa womgangatho kunye nokuqhekeka. Ukuba iintanda zenzeka kwizikhundla ezithile, nceda wazise iyunithi yokuthengisa ngexesha kwaye ugcwalise iindawo. Emva kokuzalisa, ukwandisa ukufuma komhlaba ukuze kube lula ukubuyiswa komgangatho.

Ngexesha lemvula, nceda uvale iiWindows ngononophelo hleze kunethe.

(7) Nceda unike ingqwalasela kugcino lwezifudumezi, umoya womoya kunye nezinye izixhobo zangaphakathi ukuze uthintele ukuvuza kwamanzi omgangatho omanzi. Kwimeko apho kufunyaniswe amanzi eqamza emgangathweni, kufuneka ukrazule umgangatho omanziswe ngamanzi ngokukhawuleza, kwindawo emthunzini umoya womile okanye iyunithi yokuthengisa isaziso ngexesha elifanelekileyo iqhuba.

(8) Kumnyango wendlu yangasese kunye nekhitshi, ingqalelo kufuneka ihlawulwe ekucocweni kwamanzi ngexesha elifanelekileyo.

(9) Musa ukurhuqa xa uphethe ifanitshala. Kuyacetyiswa ukuba uyiphakamise.
