Ibhodi PCB Iphini yombane igolide kunye ne-nickel sink igolide umahluko?

Ibhodi ye-PCB yegolide ifunyenwe nge-electrolysis, kwaye igolide ifunyenwe ngokuphendula kwamachiza!

Uthini umahluko phakathi kwe-PCB yegolide yombane kunye negolide etshisiweyo ye-nickel.

Ukubeka ngokulula, i-PCB yokwenza igolide yegolide, njengayo enye i-electroplating ye-PCB, ifuna umbane kunye nesilungisi. Zininzi iintlobo zenkqubo yazo, kubandakanya i-cyanide, non-cyanide system, non-cyanide system kunye ne-citric acid, sulfite njalo njalo. Isetyenziswa kushishino PCB ziinkqubo non-cyanide.

Isingxobo segolide (ikhemikhali yegolide-yesingxobo) ayifuni mbane, kodwa ibeka igolide kumphezulu ngokusebenzisa impendulo yemichiza kwisisombululo.

Banezibonelelo zabo kunye nezinto ezingalunganga. Ukongeza nokuba inikwe amandla okanye hayi, ibhodi yePCB yegolide inokwenziwa ibe nkulu kakhulu. Logama ixesha lisandiswa, kufanelekile ukuba kwenziwe iibhodi ezibhondiweyo. Ithuba lokumosha i-PCB ye-electrogold engamanzi incinci kunaleyo yegolide. Nangona kunjalo, inkqubo ye-PCB ifuna ukuhanjiswa kwebhodi yonke, kwaye ayifanelekanga ukwenza imigca ekhethekileyo.

Ukumbiwa kwezimbiwa ngegolide ngokubanzi kucekeceke kakhulu (kungaphantsi kwe-0.2 micron) kwaye ukusulungeka kwegolide kusezantsi. Ukusebenza kolwelo kunokulahlwa kuphela ukuya kuthi ga kwinqanaba elithile.

Inye yi-PCB Plating ukwenza i-nickel yegolide

Enye kukusetyenziswa kwe-sodium hypophosphite self REDOX yokusabela ukwenza umaleko wenickel, ukusetyenziswa kwempendulo yokubuyisela endaweni yenze umaleko wegolide (i-kamura (i-TSB71 inegolide ezinciphisayo), yindlela yeekhemikhali.

Ivy: Ukongeza kumahluko kwinkqubo ye-electroplating ye-PCB kunye nesingxobo, kukho lo mahluko ulandelayo:

Umaleko we-PCB we-electroplated wegolide ubungqingqwa, ubulukhuni obuphezulu, ke ihlala isetyenziselwa ukuhambisa iplagi rhoqo, njengokutshintsha kwekhadi lomnwe wegolide, njl.

Isetyenziselwa ukuwelda ngaphandle kwelothe ngenxa yomphezulu ogudileyo wephedi.
