PaPCB, Nickel inoshandiswa seyakajeka yekuvhara simbi dzinokosha uye dzisimbe. PCB yakaderera-kushushikana nickel deposits inowanzoiswa neiyo yakagadziridzwa watt nickel pleting mhinduro uye imwe sulfamate nickel kuisa mhinduro dzinowedzera dzinoderedza kushushikana. Rega Vagadziri vehunyanzvi ngavakuongorore iwe matambudziko iwayo PCB Nickel plating mhinduro kazhinji inosangana nayo kana ichishandisa?

1. Nickel process. Nekushisa kwakasiyana, kupisa kwekushambidza kunoshandiswa zvakare kwakasiyana. Mune iyo nickel inopa mhinduro nekudziya kwakanyanya, iyo nickel yekuisa dura yakawanikwa kune yakaderera kushushikana uye kushushikana kwakanaka. Iyo general inoshanda tembiricha inochengetwa pa55 ~ 60 degrees. Kana tembiricha yakanyanya kukwirira, Nickel Saline Hydrolysis ichaitika, zvichikonzera mumipini mukuvhara uye panguva imwe chete kudzora cathode polization.

2. PH kukosha. Iyo PH Kukosha kweiyo Nickel-yakarongedzwa Electrolyte ine pesvedzero yakakura pane inokonzeresa kuita uye kushanda kweElectrolyte. Kazhinji, iyo PH Kukosha kweiyo nickel plating electrolyte yePCB inochengetwa pakati pe3 kusvika ku4 Asi ph ph yakanyanya kwazvo, nekuti iyo cathode ichiramba ichisvika panguva yemagetsi, kana yakakura kupfuura 6, ichaita kuti mapini ari pachigadziko chekutanga. Nickel Pleting Solution ine Lower PH ine zvirinani ANODE kupaza uye kunogona kuwedzera zvirimo mumunyu weNickel muElectrolyte. Nekudaro, kana iyo pH yakanyanya kuderera, tembiricha yekudziya yekuwana yakajeka denderedzwa denderedzwa richaitwa. Kuwedzera nickel carbonate kana basic kabhoni carbonate inowedzera iyo ph kukosha; Kuwedzera sulfamic acid kana sulfutic acid inoderedza iyo ph kukosha, uye inotarisa uye inogadzirisa iyo pfi kukoshesa kwemaawa mana panguva yebasa.

3. Anode. Iyo yakajairika nickel plating yePCBS iyo inogona kuoneka painogona kuoneka zvese zvinoshandisa mauto, uye zvakajairika kushandisa titanium mabhasikiti seanodi yeiyo nickel kona yemukati nickel. Iyo titanium basket inofanira kuiswa muhombodo yeAnde yeiyo polypropylene zvinhu zvekudzivirira iyo anode madhaka kubva mukupindira mumhinduro, uye inofanira kucheneswa nguva dzose uye yakaongororwa kana ziso rakatsetseka.

4. kucheneswa. Kana paine kusvibiswa kwesimbe mumhinduro yekutanga, inofanira kurapwa neyakagadziriswa kabhoni. Asi nzira iyi kazhinji inobvisa chikamu chekushushikana-kusunungura mumiririri (anoshambadzira), izvo zvinofanirwa kuve zvinowedzerwa.

5. Kuongorora. Mhinduro yekutanga inofanirwa kushandisa pfungwa huru dzemitemo yekuita yakatsanangurwa mune yekuita basa. Nguva nenguva ongorora kuumbwa kwemhinduro yekutanga uye yehukama cell bvunzo, uye kutungamira dhipatimendi rekugadzira kuti rigadzirise paramita emhedzisiro yekugadzirisa maererano neakawanikwa paramita.

6. Kukurudzira. Iyo nickel yekuisa maitiro yakafanana neimwe ma electroplating maitiro. Chinangwa chekukurudzira ndechekukudziridza maitiro mazhinji ekutamisa kuti uderedze shanduko yekudzora uye kuwedzera muganho wepamusoro weiyo inotenderwa dentity density. Pane zvakare kukosha kwakanyanya kwekukurudzira mhinduro yekuisa, iyo ndeyekuderedza kana kudzivirira mapini mune nickel plating layer. Kazhinji inoshandiswa kumanikidzwa kwemhepo, cathode kufamba uye kutenderera kwekutenderera (yakasanganiswa necarbon core uye machira emucheto core filtration) kumutsa.

7. Cathode yazvino density. Cathode yazvino dentity ine mhedzisiro pane cathode ikozvino kugona, kuisirwa mwero uye kubata mhando. Paunenge uchishandisa Electrolyte nePhiza PH kune Nickel Plating, mune yakadzika yazvino nzvimbo yenzvimbo, iyo cathode yekubudirira iripo inowedzera nekuwedzera density yazvino; Mune yakakwira ikozvino density nzvimbo, iyo cathode ikozvino kushanda kwakazvimiririra kwekusimba kwazvino; Nepo kana uchishandisa yakakwira pH kana electroplating Liquid Lick nickel, hukama pakati pematunhu zvinobudirira uye huripo hwazvino hauna kukosha. Semamwe marudzi ekurongedza, huwandu hwekati yekati yazvino density yakasarudzwa kuti nickel plath inofanirwawo kuvimba nekuumbwa, kupisa kwemamiriro ekugadzirisa.
