Ziziphi iimfuno zomgangatho wokwenziwa kwePCB?

Uphuhliso lwesayensi kunye nethekhnoloji yecandelo loshishino lubonakala ngakumbi nangakumbi, ishishini lombane lelona candelo licokisekileyo ngoku, umanyano lwehlabathi, urhwebo, kunye nokusukela itekhnoloji entsha ephezulu kunye neendleko eziphantsi yindlela engenakuthintelwa yophuhliso lwe-elektroniki. ishishini, elinomgangatho ophezulu kuphela kunye nenzuzo yexabiso eliphantsi,Ukwenziwa kwePCBumgangatho ngumgangatho wenqanaba lemveliso, yingqokelela yomgangatho, isidima, uxanduva kunye nenkcubeko, Yinjongo ebesisoloko siyisukela.

Xa kuziwa kumgangatho, nokuba yibhodi yesekethe enamacala amabini okanye ibhodi yesekethe ye-4-layer PCB okanye enye.multi-layer PCB eprintiweyo ibhodi yeseketheimiba yomgangatho enxulumene namava abathengi.Abathengi bakhathazeke kakhulu malunga nomgangatho we-PCB, ke, zithini iimfuno eziqhelekileyo zomgangatho weefektri zebhodi yesekethe yePCB?

Ingaba abathengi banelisekile ngumgangatho weemveliso zokwenziwa kwe-PCB kunye nokuba iimveliso ziyahlangabezana neemfuno zabathengi ngumgangatho kuphela wokulinganisa umgangatho weemveliso.Ibhodi yesekethe eprintiweyo luhlobo lwemveliso ekhethekileyo yezixhobo zombane, umthengi omnye, uhlobo olunye, uhlobo olunye lwebhodi.Ngokwenkqubo yoxwebhu olukhethekileyo lomthengi, akukho ndawo yonke.Xa ibhodi ye-PCB enamacala amabini iyalelwa ngumthengi ekhatywayo, ibhodi yethu yesiphaluka esinamacala amabini inokuchithwa kuphela, akuyi kubakho omnye umthengi owamkelekileyo, kodwa nangona zonke iintlobo zemizobo yomgca webhodi eprintiweyo zihlukile, ubukhulu besakhiwo esahlukileyo, kodwa kwakhona babe eqhelekileyo, eqhelekileyo iimfuno zayo ezisisiseko.Iimfuno zomgangatho wefektri yebhodi yesekethe zidla ngokulandelayo:

(1) Iimfuno zembonakalo

Ababoneleli bokwenziwa kwePCB badla ngokufuna inkangeleko engqongqo ngakumbi, engadingi kungcoliseka, ukufakwa, ukuprintwa kweminwe kunye ne-oxidation kumphezulu, ukuze kungachaphazeli ukuwelda kunye nokugquma.Umbala kunye nombala wepateni yokumelana ne-welding iyahambelana, ngaphandle kokuxubha, ukungabikho okanye ukuphambuka, i-oyile ibona, xa ichaphazela i-welding.Umphetho we-PCB ugudile kwaye ucocekile, ngaphandle kwe-bump okanye i-burr, kwimeko yokuchaphazela ubungakanani bendibano kunye nokugquma.I-uniform wire, akukho corrosion, notch, i-copper eseleyo, ukukhusela impembelelo yokusebenza kombane.Uphawu uphawu lucacile, alunakuncamathisela olufundekayo, ukuthintela impembelelo yokudibanisa kunye nokugcinwa.Akukho mikrwelo kumphezulu ukuphepha ukuchaphazela indibano ye-welding kunye nokusebenza kombane.Akukho gwebu okanye delamination phakathi kwe-conductor okanye i-insulating layers, ngakumbi ii-PCB ze-multilayer, ukunqanda ukuchaphazela iimpawu zoomatshini nezombane.

(2) Iimfuno zokusebenza kombane

Kubaluleke kakhulu ukuseta umsantsa ofanelekileyo wombane phakathi kweengcingo zebhodi yeesekethe ezininzi.Isithuba esifanelekileyo somgca sinokuthintela ukukhanya kunye nokwaphuka phakathi kwabaqhubi abafanelekileyo kumsebenzi weemveliso zokucubungula i-PCB, kwaye banokuphumelela ngempumelelo uphicotho lwemigangatho yokhuseleko lwemveliso efanelekileyo.Kwimigangatho yoshishino kunye nokhuseleko lwebhodi yesekethe kunye neemveliso ze-PCB, ii-voltages ezahlukeneyo zokusebenza, iimeko ezahlukeneyo zesicelo kunye nezinye izinto zinemimiselo eyahlukileyo kwi-gap yombane kunye nomgama we-creepage phakathi kwabaqhubi.

(3) Iimfuno zokusebenza koomatshini

Ibhodi yesekethe ifuna ukuba ipleyiti yobhedu kufuneka ibhakwe ngaphambi kokuvulwa ukuze kuqinisekiswe ukuba i-resin ye-vapor volatilization resin kwi-plate iphiliswa ngokupheleleyo;xa uvula izinto eziphathekayo, sebenzisa ngokungqongqo ngokuhambelana ne-warp kunye nolwalathiso lwe-weft kumyalelo wokuvula;ngexesha le-laminating kunye ne-typesetting, i-laminating kunye ne-typesetting iya kuqhutywa ngokuhambelana ne-warp kunye ne-weft imiyalelo yeepleyiti ezicutshungulweyo ze-PCB.Umkhomba-ndlela we-warp kunye ne-weft uya kwahlulwa kuqala kwaye ukusetha ngohlobo kuya kuqhutywa ngokuhambelana ne-warp eyahlukileyo kunye nezalathiso ze-weft zokuqinisekisa ukuba umkhombandlela we-warp kunye ne-weft uyahambelana.Akukho ukulungiswa kwangasese kwexesha elibandayo eliya kuvunyelwa, kwaye iirekhodi ziya kwenziwa ukuze kuqinisekiswe ukuba uxinzelelo kwiiplate lukhululwe ngokupheleleyo kwaye i-resin iphiliswe ngokupheleleyo.Xa umlingiswa webhodi yesekethe yebhodi yesiphaluka ibhakwa kwiqondo lokushisa eliphezulu, ishelufu kufuneka ilungiswe ngokobukhulu bebhodi.Ibhodi ayivumelekanga ukugoba okanye ukujija xa i-socket ifakwe.Ubungakanani abufani nesokhethi esahlukileyo sokubhaka.

(4) Ukumelana nokusingqongileyo kunye nezinye iimfuno zokusebenza

Ibhodi yesekethe ye-multi-layer inokumelana nokusingqongileyo, ukuxhathisa ukubola, ukuxhathisa ukufuma, ukumelana nokupheka, ukuxhathisa impembelelo yeqondo lokushisa kunye nezinye iimpawu.

Ukwenziwa komgangatho wemveliso ye-PCB ye-allegro ihamba kuyo yonke inkqubo yokwenziwa kwemveliso, kwaye umgangatho wemveliso we-PCB unxulumene nayo yonke inkqubo yokuvelisa.Wonke umzi-mveliso webhodi yesekethe kufuneka uhlawule ngokukodwa umgangatho, umgangatho uveliswa, ungahlolisiswa.Zicinge njengomthengi wenkqubo yangaphambili kunye nenkqubo elandelayo njengomthengi wakho.Emva kwebhodi yesekethe nganye liqela labasebenzi bokuqinisekisa umgangatho abathe cwaka beqhuba uhlolo lomgangatho, inkqubo egqibeleleyo yolawulo lomgangatho iyafuneka kuyo yonke imveliso yokwenziwa kwePCB.
