Uyilo lwe-PCB kunye nenkqubo yemveliso ineenkqubo ezininzi ezinokuba ngama-20,i-tin empofukwibhodi yesekethe inokukhokelela kumgca wesanti, ukuwa kocingo, amazinyo enja yomgca, isekethe evulekileyo, umgca womngxuma wesanti;Pore copper obhityileyo umngxuma olunzulu ngaphandle kobhedu;Ukuba umngxuma ubhedu obhityileyo unzima, umngxuma ubhedu ngaphandle kobhedu;I-Detin ayicocekanga (i-return tin amaxesha iya kuchaphazela i-coating detin ayicocekanga) kunye nezinye iingxaki ezisemgangathweni, ngoko ke ukudibana kwe-tin ehluphekileyo kaninzi kuthetha ukuba imfuneko yokuphinda i-weld okanye ilahle umsebenzi wangaphambili, kufuneka yenziwe kwakhona.Ke ngoko, kushishino lwePCB, kubaluleke kakhulu ukuqonda oonobangela betoti engalunganga
Inkangeleko yetoti ehlwempuzekileyo inxulumene ngokubanzi nococeko lwebhodi engenanto yePCB.Ukuba akukho lungcoliso, ngokusisiseko akuyi kubakho inkonkxa engaphucukanga.Okwesibini, i-solder ngokwayo ihlwempuzekile, ukushisa kunye nokunye.Emva koko ibhodi yesekethe eprintiweyo ibonakala ikakhulu kula manqaku alandelayo:
1. Kukho ukungcola kweengqungquthela kwi-plate coating, okanye kukho amaqhekeza okugaya asele phezu komgca womgca ngexesha lokuvelisa i-substrate.
2. Ibhodi enegrisi, ukungcola kunye nezinye ii-sundries, okanye kukho intsalela yeoli ye-silicone.
3. Umphezulu weplate unephepha lombane kwi-tin, i-plate surface coating inobumdaka obuncinane.
4. Ukwaleka okunokwenzeka okuphezulu kurhabaxa, kukho into evuthayo yepleyiti, icwecwe lomphezulu weplate alinakuba kwitoti..
5. I-oxidation yomphezulu we-tin kunye nobuthuntu komphezulu wobhedu we-substrate okanye iinxalenye zinobuzaza.
6. Elinye icala lokwaleka lugqityiwe, elinye icala lokwaleka libi, icala lomngxuma elinokubakho liphantsi linomphetho oqaqambileyo ocacileyo.
7. Imingxunya enokubakho ephantsi inomphetho oqaqambileyo ocacileyo, ukhuko oluphezulu olunokubakho, kukho into evuthayo yepleyiti.
8. Inkqubo ye-welding ayiqinisekisi ukushisa okwaneleyo okanye ixesha, okanye ukusetyenziswa ngokuchanekileyo kwe-flux
9. Indawo enkulu enokubakho ephantsi ayinakuthotywa, umphezulu webhodi unombala obomvu obomvu okanye obomvu, elinye icala lengubo ligqityiwe, elinye icala lengubo libi.
