Pane pezvakaitwa akawanda pamusoro pemvura akadhindwa redunhu bhodhi : kupfeka PCB bhodhi (hapana pose kurapwa), OSP, Hot Air Nhambo (vatungamirire netini, kutungamirira-isina mugaba), ra goridhe, kunyudza goridhe etc. idzi dzinotipfuura kuoneka.
Kusiyana kunyudza goridhe uye ra goridhe
Kunyudza goridhe inzira kwemakemikari deposition. A kwemakemikari rukoko chakaumbwa makemikari oxidation-rutapudzo kuita. Kazhinji, pakukora achiri gobvu. Zviri mhando kwemakemikari nickel-goridhe-goridhe rukoko deposition nzira, uye anogona kuzadzisa gobvu goridhe rukoko.
Gold yakanamirwa pamifananidzo anoshandisa nheyo electrolysis, rinonziwo electroplating. Most dzimwe simbi pamusoro kurapa vari electroplated. 
In the actual product application, 90% of the gold pcb board is the immersed gold pcb board,because the poor solderability of the plated circuit board is his fatal flaw, and it is also the direct cause of many companies to give up the gold plating process!
Kunyudza goridhe rikurumidze rakachengetedzwa pamusoro pemvura akadhindwa redunhu pamapuranga pamwe kugadzikana ruvara, kupenya zvakanaka, wakatsetseka yakanamirwa pamifananidzo, uye solderability zviri nickel goridhe yakanamirwa pamifananidzo yakanaka. Kumboda inogona rakakamurwa muzvikamu zvina: pre-kurapwa (nokubviswa mafuta, Micro-etching, activation, post-Dip), nickel kwemvura, rinorema goridhe, post-kurapwa (tsvina mvura yokushambidza Di mvura yokushambidza, nokuomesa). Kunyudza goridhe ukobvu iri pakati 0.025-0.1um.
Gold rinoshandisirwa pamusoro Mabatirwo akadhindwa redunhu mapuranga nokuti ayo yakakwirira magetsi conductivity, zvakanaka oxidation nemishonga, uye refu lifespan. Vazhinji kushandiswa mapuranga anokosha, nendarama munwe pcb mapuranga, etc. inokosha musiyano pakati pamapuranga-akaafukidza nendarama uye mapuranga-kunyudzwa ndarama kuti goridhe yakanamirwa pamifananidzo iri rakaoma. Gold (abrasion nemishonga), ndarama dzamutswa goridhe (kwete kupfeka nemishonga). 
1. The crystal structure formed by Immersion Gold and Gold Plating is different. Immersion Gold is much thicker than Gold Plating. Immersion Gold will be golden yellow and yellower than Gold Plating (this is the method of distinguishing between gold plating and heavy gold plating.) a) Gold plating will be slightly white (nickel color).
2. sekristaro mamiriro inoumbwa nokunyudza goridhe uye nendarama yakanamirwa pamifananidzo yakasiyana. Kunyudza ndarama nyore weld pane goridhe yakanamirwa pamifananidzo uye haungavhenekeri nomoto zvakaipa. Kunetseka pamusoro bhodhi immerison ndarama nyore kuzvidzora, uye zvinonyanya zvinoita kuti Muitiro unobatanidza nokuda waakaita zvigadzirwa. Panguva iyoyowo, nekuti ndarama yakawanda goridhe-akaafukidza kupfuura goridhe, iri-neminwe goridhe goridhe munwe hakusi wearable (zvinokanganiswa bwendefa rendarama).
3. Kune chete nickel-goridhe pamusoro ikanyanya iri-kunyudzwa goridhe pcb bhodhi isu takanzwa pamurayiro chiratidzo Kupfuudzwa paganda inoita vasakanganise chiratidzo kwemhangura rukoko.
4. kunyudza goridhe zvinonyanya gobvu kupfuura goridhe yakanamirwa pamifananidzo sekristaro mamiriro, kwete nyore kugadzira oxidation.
5. Nokuwedzera kudiwa akadhindwa redunhu bhodhikubudiswa zvakarurama, mutsetse upamhi, spacing yasvika 0.1mm pazasi. Gold yakanamirwa pamifananidzo asingatani goridhe pfupi redunhu. Ndiro yegoridhe chete ane nickel uye ndarama pamusoro ikanyanya, saka hazvisi nyore kubudisa ndarama pfupi redunhu.
6. kunyudza goridhe chete ane nickel goridhe pamusoro ikanyanya, saka solder muchipikisa pamutsetse iri zvakawanda zvakasimba waakaita kuti yemhangura rukoko. The purojekiti hakumbokanganisi kuti spacing kana muripo.
7. Nokuti yepamusoro zvinodiwa pcb puranga, flatness zvinodiwa nani, mukuru kushandiswa kunyudzwa goridhe , kunyudza goridhe kazhinji asimo pashure paungano dema bonde chinonakidza. The flatness uye basa upenyu hwendefa nendarama nani kupfuura hwendefa goridhe.
Saka Parizvino mafekitari vakawanda vanoshandisa kunyudza goridhe muitiro kubudisa ndarama pcb pepuranga .However, basa kunyudzwa goridhe muitiro iri iyo yaidhura kupfuura ndarama-yakanamirwa pamifananidzo muitiro (more goridhe kugutsikana), saka kuchine vazhinji kuderedzwa akatemerwa mutengo zvigadzirwa kushandisa pezvakaitwa-ra goridhe (akadai kure kuzvidzora ukomba, chitoyi mapuranga).
