Kwamitin PCB Electroplating shine samun zinari ta hanyar lantarki, kuma raguwar sinadarai shine samun zinari ta hanyar rage halayen sinadarai. A taƙaice, PCB electroplating zinariya, kamar sauran PCB electroplating, na bukatar iko da gyara. Akwai nau’o’in matakai da yawa, ciki har da tsarin cyanide, wanda ba na cyanide ba, da kuma tsarin da ba na cyanide ba, irin su citric acid da nau’in sulfite. Ana amfani da duk tsarin da ba na cyanide ba a cikin masana’antar PCB.

Sinadarin zinare (electroless gold plating) baya buƙatar samun kuzari, yana sanya zinari akan allo ta hanyar sinadarai a cikin maganin.

Suna da nasu amfani da rashin amfani. Baya ga kunnawa amma ba kunnawa ba, allon PCB na iya yin kauri sosai, idan dai an tsawaita lokacin, ya dace da allunan haɗin gwiwa. Damar yin watsi da PCB kera potion na zinari ya yi ƙasa da na zinare sinadarai. Koyaya, zinaren lantarki na PCB yana buƙatar haɗawa da dukkan allo, kuma bai dace da layukan bakin ciki na musamman ba.

Zinare sinadari gabaɗaya sirara ne (kasa da 0.2 microns), kuma tsarkin zinari ba shi da ƙarfi. Za a iya jefar da ruwan aiki kawai idan aka yi amfani da shi zuwa wani iyaka.

Daya shine PCB electroplating don samar da nickel zinariya

Ɗayan shine amfani da sinadarin sodium hypophosphite na kansa oxidation-reduction reaction don samar da Layer nickel, da kuma wani canji don samar da launi na zinariya (Uemura’s (TSB71 yana tare da zinare da aka rage)), wanda shine hanyar sinadarai.

Ivy: Baya ga bambance-bambancen tsari tsakanin PCB electroplating da zinare nutsewa, akwai bambance-bambance masu zuwa:

PCB electroplating zinariya Layer yana da kauri da wuya, don haka yawanci ana amfani dashi don yawan toshewa da saka sassa masu zamewa, kamar yatsun zinare na katunan canza;

Zinare na nutsewa yana da kyau don hawa saboda shimfidar saman kushin kuma ana amfani dashi don siyar da babu gubar.
