Chifukwa chiyani amatero PCB electroplating golide wosanjikiza kukhala wakuda?

1. Potion status ya electroplated nickel thanki

Ndiyeneranso kulankhula za thanki ya nickel. Ngati mafuta a faifi tanki sakusungidwa bwino kwa nthawi yayitali, ndipo chithandizo cha kaboni sichikuchitika munthawi yake, nickel wosanjikiza pambuyo pa electroplating imatulutsa makhiristo osalala, kuuma kwa plating kumawonjezeka, komanso kuwonongeka kwa brittleness. kupaka kudzawonjezeka. Pazovuta kwambiri, kuyanika kwakuda kudzachitika. Izi ndichifukwa choti anthu ambiri amakonda kunyalanyaza mfundo zazikuluzikulu zowongolera. Komanso nthawi zambiri ndi chifukwa chachikulu cha mavuto. Chifukwa chake, chonde yang’anani mosamala momwe mzere wopangira fakitale yanu ulili, fufuzani mofananiza, ndikuchita bwino kwambiri pakanthawi kochepa kuti mubwezeretse ntchito ya potion ndikuyeretsa njira ya electroplating.

2. Makulidwe kuwongolera kwa electroplated nickel wosanjikiza

Aliyense ayenera kulankhula zakuda kwa electroplated golide wosanjikiza, zingakhale bwanji makulidwe a electroplated nickel wosanjikiza. M’malo mwake, PCB yopaka golide wosanjikiza nthawi zambiri imakhala yopyapyala kwambiri, kuwonetsa kuti mavuto ambiri omwe amakhala pamwamba pa golide wopaka golide amayamba chifukwa cha kusagwira bwino ntchito kwa faifi tambala ya electroplating. Nthawi zambiri, kupatulira kwa nickel ya electroplated kumapangitsa kuti zinthu ziwonekere kukhala zoyera komanso zakuda. Chifukwa chake, uku ndiye kusankha koyamba kwa akatswiri opanga fakitale ndi akatswiri kuti awone. Nthawi zambiri, makulidwe a nickel wosanjikiza amafunikira electroplated mpaka pafupifupi 5 mam kuti akhale okwanira.

3. Kuwongolera kwa silinda yagolide

Tsopano zikubwera ku ulamuliro wa silinda yagolide. Nthawi zambiri, bola mutakhalabe ndi kusefera kwabwino kwa potion ndi kubwezeretsanso, kuyipitsa ndi kukhazikika kwa silinda yagolide kudzakhala kwabwinoko kuposa kwa silinda ya nickel. Koma muyenera kusamala kuti muwone ngati mbali zotsatirazi ndi zabwino:

(1) Kodi zowonjezera za silinda yagolide ndizokwanira komanso zochulukirapo?

(2) Kodi mtengo wa PH wa potion umayendetsedwa bwanji? (3) Nanga bwanji mchere wa conductive?

Ngati palibe vuto ndi zotsatira zoyendera, gwiritsani ntchito makina a AA kuti mufufuze zonyansa zomwe zili mu yankho. Tsimikizirani momwe thanki yagolide ilili. Pomaliza, musaiwale kuyang’ana ngati pakatikati pa zosefera zagolide sizinasinthidwe kwa nthawi yayitali.
