1. Tsarin zinari na nutsewa: Manufar tsarin zinari na nutsewa shine don saka suturar nickel-gold tare da barga launi, haske mai kyau, mai laushi mai laushi da mai kyau solderability a saman PCB, wanda za'a iya raba asali zuwa matakai hudu: pretreatment. (Degreeasing, micro-etching, kunnawa, post-dipping), nickel immersion, immersion zinariya, bayan jiyya, (wanke gwal, DI wanka, bushewa).
2. Tin da aka fesa gubar: Zazzaɓin eutectic mai ɗauke da gubar ya yi ƙasa da na alloy maras gubar.Ƙimar ƙayyadaddun adadin ya dogara da abun da ke ciki na gami da ba tare da gubar ba.Misali, eutectic na SNAGCU shine digiri 217.Matsakaicin zafin jiki shine eutectic zazzabi da 30-50 digiri, dangane da abun da ke ciki.Ainihin daidaitawa, eutectic mai jagora shine digiri 183.Ƙarfin injina, haske, da sauransu. gubar sun fi rashin gubar.

(1) Lalacewar gefe.Lalacewar gefe al'amari ne na nutsewa ko nutsewar gefan madugu wanda ke haifar da etching.Matsakaicin lalatawar gefe yana da alaƙa da maganin etching, kayan aiki da yanayin tsari.Karancin lalatar gefen gefe shine mafi kyau.
(2) Rufe yana faɗaɗa.Faɗaɗɗen rufin yana faruwa ne saboda ƙyalli na rufin, wanda ya sa nisa na gefe ɗaya na waya ya wuce nisa na farantin ƙasa da aka gama.
6. Zinariya
Plating na zinari yana da kyakkyawan ƙarfin lantarki, ƙanana da tsayayye juriya da kyakkyawan juriya, kuma shine mafi kyawun kayan plating don bugu na allon kewayawa.A lokaci guda, yana da kyakkyawan kwanciyar hankali da sinadarai, kuma ana iya amfani da shi azaman lalata-resistant, solderable da kariya shafi a saman Dutsen PCBs.
7. Narke mai zafi da matakan iska mai zafi
(1) Narke mai zafi.pcb mai rufi tare da Sn-Pb alloy yana mai zafi zuwa sama da wurin narkewa na Sn-Pb alloy, don haka Sn-Pb da Cu suna samar da fili na karfe, ta yadda Sn-Pb shafi ya kasance mai yawa, mai haske kuma ba tare da pinhole ba, kuma da lalata juriya da solderability na shafi an inganta.jima'i.Hot-narke da aka saba amfani da glycerol hot-narke da infrared zafi-narke.
(2) Matsayin iska mai zafi.Har ila yau, an san shi da feshin kwano, allon da'ira mai rufaffen abin rufe fuska ana daidaita shi da juyi ta iska mai zafi, sannan ya mamaye wurin narkakken solder, sannan ya wuce tsakanin wuƙaƙen iska guda biyu don busa abin da ya wuce gona da iri don samun haske, uniform, santsi. solder shafi.Kullum, yawan zafin jiki na solder bath ana sarrafa shi a 230 ~ 235, ana sarrafa yawan zafin jiki na wuka na iska a sama da 176, lokacin waldawar tsoma shine 5 ~ 8s, kuma ana sarrafa kauri na shafi a 6 ~ 10 microns.
Hukumar da'ira Buga mai gefe Biyu
