Waxaa jira geedi socodka dhowr dushiisa oo ka mid ah daabacay guddiga circuit : guddiga PCB qaawan (daawaynta dusha lahayn), OSP, Hot Air Nigeria (daasadda hogaanka, iyo waxa daasadda keeni-free), dahab dahaadhay, dahab Immersion iwm badan yihiin la arki karo.
Farqiga u dhexeeya dahab Immersion iyo dahab dahaadhay
dahab Immersion waa hab ka mid ah dhigaalka kiimikada. lakabka kiimikada A waxaa la aasaasay by reaction kiimikada lagu qayilo-hoos u. Guud ahaan, oo dhumucdiisuna waa mid yara qaro weyn. Waa nooc ka mid ah habka dhigaalka lakabka nickel-dahab-dahab kiimikada, iyo gaari karo lakabka qaro weyn oo dahab ah.
Dahaadhay dahab isticmaalaa mabda'a electrolysis, sidoo kale loo yaqaan electroplating. Inta kale dusha biraha ayaa sidoo kale 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!
Habka dahab Immersion shubo dushiisa oo ka mid ah loox wareeg daabacan la midab deggan, dhalaalka wanaagsan, dahaadhay siman, iyo solderability wanaagsan oo dahaadhay dahab nickel. Asal ahaan waxa loo qaybin karaa afar marxaladood:-daaweyn pre (saarida saliidda, micro-Iagu, hawlgelinta, post-maquufin), roobab nickel, dahab culus,-daweynta post (qashinka biyo lagu dhaqo, biyo DI dhaqo, qalajiyo). Oo dhumucdiisuna waxay dahab Immersion waa inta u dhaxaysa 0.025-0.1um.
Gold waxaa laga codsadaa in daawaynta dushiisa oo looxyada ku wareeg daabacan ee sababta oo ah conductivity sare korontada, iska caabin ah lagu qayilo wanaagsan, iyo cimri dheer. Waxaa guud ahaan waxaa loo isticmaalaa sida looxyada muhiimka ah, loox PCB farta dahab ah, iwm Farqiga u dhexeeya aasaasiga loox oo loox dahab-Hawiyaha dahab qufilan waa in dahaadhay dahab ah waa ku adag tahay. Gold (abrasion adkaysta), dahab waa dahab jilicsan (inayan xidhan waxa u adkaysta). 
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. Dhismaha crystal ayaa la sameeyey by dahab immersion iyo dahaadhay dahab ah waa ka duwan yahay. dahab Immersion waa u fududahay in Weld badan dahaadhay dahab ah oo aan ka dhigi doonaa in alxanka xun. stress, oo loox dahab immerison waa u fududahay in ay gacanta ku, iyo farabadnaa sahla habka lagala kulmo wax soo saarka addoonsi ah. Isla mar ahaantaana, maxaa yeelay, dahab badan yahay dahab-plated yihiin dahab, farta dahab-fingered dahab ah ma aha wearable (ceebaha of saxan oo dahab ah).
3. Waxaa jira oo keliya nickel-dahab on suufka ee dahabka-Hawiyaha guddiga PCB .Oo gudbinta signal in saamayn maqaarka wax saameyn ah kuma signal ee lakabka copper ah.
4. Immersion dahab ah waa ka badan tahay daar dhismeedka crystal dahaadhay dahab ah, ma fududa in la soo saaro qayilo.
5. Iyadoo baahida sii kordhaysa for daabacay guddiga circuitsax processing, width line, kala dheereynta ay gaareen 0.1mm hoos. Dahaadhay dahab ah waa mid u nugul dahab circuit gaaban. Saxan oo dahab ah waxa uu leeyahay oo kaliya nickel iyo dahab on suufka, sidaas darteed ma fududa in ay soo saaraan dahab circuit gaaban.
6. dahab bilowga ah waxa uu leeyahay oo kaliya dahab nickel on suufka, sidaas Alxan hor joogsada on line waa ka badan si adag addoonsi lakabka copper ah. Mashruucan ayaa wax saamayn ah kuma kala dheereynta marka magdhow.
7. Wixii shuruudaha sare ee guddiga PCB ah, shuruudaha flatness ka khayr, isticmaalka guud oo dahab ah bilowga ah , dahab bilowga guud ahaan uusan ka muuqan ka dib markii shirkii reer ugub ku derin madow. Nolosha flatness iyo hawshii saxan dahab ah ka khayr badan in of saxan oo dahab ah.
Sidaas Waqtigan xaadirka ah warshado badan waxay isticmaalaan habka immersion dahab ah in ay soo saaraan guddiga PCB dahab ah .Si kastaba ha ahaatee, habka dahab-Hawiyaha waa ka qaalisan yihiin habka dahab-dahaadhay ah (content dahab ka badan), sidaa darteed wali waxaa jira tiro badan oo ah waxyaabaha low-hoodu isticmaalaya geedi socodka dahab-dahaadhay (sida darfaha hago, loox toy).
