Iibhodi yesekethe PCBitshintsha rhoqo kunye nenkqubela phambili yeteknoloji yenkqubo, kodwa ngokomgaqo, ibhodi yesekethe ye-PCB epheleleyo idinga ukuprinta ibhodi yesekethe, emva koko unqumle ibhodi yesekethe, ukucubungula i-laminate yobhedu, ukudlulisa ibhodi yesiphaluka, i-Corrosion, i-drilling, i-pretreatment, kunye ne-welding inokunikwa amandla kuphela emva kwezi nkqubo zemveliso.Oku kulandelayo kukuqonda okunzulu kwenkqubo yokuvelisa ibhodi yesekethe yePCB.
Yila umzobo weskim ngokweemfuno zomsebenzi wesekethe.Uyilo lomzobo weskimu lusekelwe ikakhulu ekusebenzeni kombane wecandelo ngalinye ukuba lakhiwe ngokufanelekileyo njengoko kufuneka.Umzobo unokubonisa ngokuchanekileyo imisebenzi ebalulekileyo yebhodi yesekethe yePCB kunye nobudlelwane phakathi kwamacandelo ahlukeneyo.Uyilo lomzobo weskimu linyathelo lokuqala kwinkqubo yokuvelisa iPCB, kwaye linyathelo elibaluleke kakhulu.Ngokuqhelekileyo isoftwe esetyenziselwa ukuyila i-schematics yesekethe yi-PROTEl.
Emva kokuba uyilo lweskimu lugqityiwe, kuyimfuneko ukuqhubela phambili ukupakisha icandelo ngalinye nge-PROTEL ukuvelisa kunye nokuqonda igridi enenkangeleko efanayo kunye nobukhulu bamacandelo.Emva kokuguqula ipakethe yecandelo, phumeza Hlela/Setha Okukhethwayo/iphini 1 ukuseta indawo yereferensi yephakheji kwiphini lokuqala.Emva koko uphumeze iNgxelo/yeCandelo loMgaqo wokujonga ukuseta yonke imigaqo ekufuneka ijongwe, kwaye Lungile.Ngeli xesha, iphakheji isekiwe.
Yenza ngokusesikweni iPCB.Emva kokuba uthungelwano luveliswe, indawo yecandelo ngalinye kufuneka ibekwe ngokuhambelana nobukhulu bephaneli yePCB, kwaye kuyimfuneko ukuqinisekisa ukuba iinkokeli zecandelo ngalinye azinqumli xa zibeka.Emva kokuba ukubekwa kwamacandelo kugqityiwe, uhlolo lwe-DRC luye lwaqhutywa ekugqibeleni ukuze kupheliswe iimpazamo zephini okanye ukuwela okukhokelela kwilungu ngalinye ngexesha locingo.Xa zonke iimpazamo zisusiwe, inkqubo yoyilo pcb epheleleyo igqityiwe.
Shicilela ibhodi yesekethe: Shicilela ibhodi yesekethe ezotyiweyo ngephepha lokudlulisa, nikela ingqalelo kwicala elityibilikayo elijongene nawe, printa ngokubanzi iibhodi zeesekethe ezimbini, oko kukuthi, printa iibhodi zeesekethe ezimbini kwiphepha elinye.Phakathi kwabo, khetha enye enefuthe elihle lokushicilela ukwenza ibhodi yesiphaluka.
Sika i-laminate ye-copper clad, kwaye usebenzise ipleyiti ye-photosensitive ukwenza yonke inkqubo yomzobo webhodi yesekethe.I-laminates ene-Copper-clad, oko kukuthi, iibhodi zeesekethe ezigutyungelwe ngefilimu yobhedu kumacala omabini, zinqumle i-laminates ene-copper-clad kubukhulu bebhodi yesiphaluka, kungekhona enkulu kakhulu, ukugcina izinto.
Ukulungiswa kwangaphambili kweelaminates ezigqunywe ngobhedu: sebenzisa i-sandpaper ecikizekileyo ukugudisa umaleko we-oxide kumphezulu we-laminates ezigqunywe ngobhedu ukuze uqinisekise ukuba i-toner kwiphepha lokudlulisa i-thermal inokuprintwa ngokuqinileyo kwi-laminates yobhedu xa uhambisa ibhodi yesekethe.Ukugqiba ngokukhazimla ngaphandle kwamabala abonakalayo.
Ukutshintshela ibhodi yesekethe eprintiweyo: Sika ibhodi yesekethe eprintiweyo kwisayizi efanelekileyo, unamathisele icala lebhodi yesekethe eprintiweyo kwi-laminate ye-copper clad, emva kokulungelelaniswa, faka i-copper clad laminate kumatshini wokutshintshwa kwe-thermal, kwaye uqinisekise ukutshintshwa xa ubeka kwiPhepha. ayilungiswanga kakuhle.Ngokuqhelekileyo, emva kokudluliselwa kwe-2-3, ibhodi yesiphaluka inokudluliselwa ngokuqinileyo kwi-laminate yobhedu.Umatshini wokudlulisa i-thermal ufuduselwe kwangaphambili, kwaye ubushushu bubekwe kwi-160-200 degrees Celsius.Ngenxa yobushushu obuphezulu, nceda uqaphele ukhuseleko xa usebenza!
Ibhodi yesiphaluka ye-Corrosion, i-reflow soldering machine: jonga kuqala ukuba ukuhanjiswa kugqityiwe kwibhodi yesiphaluka, ukuba kukho iindawo ezimbalwa ezingadluliswanga kakuhle, ungasebenzisa ipeni elimnyama elisekelwe kwioli ukulungisa.Emva koko inokugqwala.Xa ifilimu yobhedu evezwe kwibhodi yesekethe ihlanjululwe ngokupheleleyo, ibhodi yesiphaluka ikhutshwe kwi-liquid corrosive kwaye ihlanjululwe, ukwenzela ukuba ibhodi yesekethe ihlanjululwe.Ukubunjwa kwesisombululo sokutshabalalisa kugxininiswe i-hydrochloric acid, i-hydrogen peroxide edibeneyo, kunye namanzi kwisilinganiselo se-1: 2: 3.Xa ulungiselela isisombululo sokutshabalalisa, yongeza amanzi kuqala, uze udibanise i-hydrochloric acid edibeneyo kunye ne-hydrogen peroxide.Ukuba i-hydrochloric acid egxininisiweyo, i-hydrogen peroxide egxininisiweyo okanye isisombululo esinomsoco asiyi kuqaphela ukutshiza esikhumbeni okanye kwimpahla kwaye uyihlambe ngamanzi acocekileyo ngexesha.Ekubeni kusetyenziswa isisombululo esinamandla e-corrosive, qiniseka ukuba ubeke ingqalelo kukhuseleko xa usebenza!
Ukugaya ibhodi yesekethe: Ibhodi yesekethe kukufaka amacandelo e-elektroniki, ngoko ke kuyimfuneko ukubetha ibhodi yesekethe.Khetha iidrill ezahlukeneyo ngokobunzima bezikhonkwane zezinto zombane.Xa usebenzisa i-drill yokubhoboza imingxuma, ibhodi yesiphaluka kufuneka icinezelwe ngokuqinileyo.Isantya se-drill akufuneki sicothe kakhulu.Nceda ujonge umsebenzisi ngononophelo.
Ukunyangwa kwebhodi yesekethe: Emva kokugrumba, sebenzisa i-sandpaper entle ukupolisha i-toner egqume ibhodi yesekethe, kwaye ucoce ibhodi yesekethe ngamanzi acocekileyo.Emva kokuba amanzi omile, sebenzisa amanzi epineyini kwicala kunye nesekethe.Ukuze ukhawuleze ukuqina kwe-rosin, sisebenzisa i-heat blower ukutshisa ibhodi yesiphaluka, kwaye i-rosin inokuqina kwimizuzu emi-2-3 kuphela.
I-Welding electronic components: Emva kokuba umsebenzi we-welding ugqityiwe, qhuba uvavanyo olubanzi kwibhodi yesekethe yonke.Ukuba kukho ingxaki ngexesha lovavanyo, kuyimfuneko ukugqiba indawo yengxaki ngokusebenzisa umzobo oqingqiweyo owenziwe kwinqanaba lokuqala, uze uphinde uthengise okanye utshintshe inxalenye.isixhobo.Xa uvavanyo luphumelele ngempumelelo, ibhodi yesekethe yonke igqityiwe.
