Yakazara PCB electroplating maitiro inosanganisira post-kurapwa kwe electroplating. Zvakare kutaura, ese electroplating anotorwa-mushure mushure mekusarudzwa. Iyo yakapusa post-kurapwa inosanganisira inopisa mvura yekuchenesa uye kuomesa. Uye kupfeka kwakawanda kunodawo passivation, kuchenesa, kudhaya, kuisa chisimbiso, kupenda uye kumwe kugadzirwa kwepamberi, kuitira kuti iko kupfekedza kuita kuve nani kutamba uye kusimbisa.

Maitiro ekuita nePCB mushure me electroplating

Post-raresi yekurapa nzira dzinogona kukamurwa muzvikamu gumi nezviviri zvinotevera:

1, kuchenesa;

2, yakaoma;

3, kubviswa kwehydrogen;

4, makorari (zvemaziso makorari uye electrochemical makorari);

5, kufambisa;

6, kupenda;

7, kudhaya;

8, yakavharwa;

9, dziviriro;

10. Kupenda;

11, isina kukodzera kupfeka kubviswa;

12, bhati kupora.

Zvinoenderana nekushandiswa kana dhizaini yesimbi kana isiri-yesimbi zvigadzirwa zvemagetsi, kurapwa kunotevera kunogona kugoverwa muzvikamu zvitatu, zvinoti kuvandudza kana kuwedzera kuchengetedza, kushongedza uye kushanda.

(1) Inodzivirira mushure mekurapa

Kunze kwe chrome yakanamirwa pamadziro, zvimwe zvese zvinodzivirira, kana zvichishandiswa sekupfeka kwepamusoro, zvinofanirwa kurapwa zvakanaka mushure mekuchengetedza kana kuwedzera hunhu hwavo hwekudzivirira. Iyo yakajairika post-kurapwa nzira ndeye passivation. Kuchengetedza zvakakwirira zvinodiwa zvepamusoro pekuputira kugadzira, semuenzaniso, kufukidza mwenje yekugadzirisa, kubva pakudzivirirwa kwezvakatipoteredza uye mutengo wekufunga, inogona kushandisa mvura yakajeka yekupfeka.

(2) yekushongedza post kurapwa

Kunoshongedza post – kurapwa chiitiko chakajairika mune isiri – simbi yakanamirwa pamadziro. Semuenzaniso, kuisirwa kwegoridhe rekunyepedzera, kutevedzera sirivheri, mhangura yekare, kukwesha, kuchenesa kana kudaya uye kumwe kurapwa kwounyanzvi. Aya marapirwo anodawo kuti pamusoro pacho pakafukidzwa neakajeka kupfeka. Dzimwe nguva shandisa chromatic yakajeka yekupfeka kunyangwe, semuenzaniso kuteedzera aureate, tsvuku, girini, yepepuru kumirira kupenda kwemavara.

(3) Inoshanda post-kugadzirisa

Mimwe isiri-yesimbi electroplating zvigadzirwa zvakagadzirirwa zvinoshanda zvinoshanda, uye kumwe kurapwa kunoshanda kunodiwa mushure meelectroplating. Semuyenzaniso, sezvo pamusoro unhani pamusoro rinobva kudzivirirwa rukoko, sezvo pemvura solder unhani pamusoro nomoto unhani, etc.
