Wopanga gulu lozungulira: kusanthula kwa oxidation ndi njira yopititsira patsogolo kumiza golide pcb board?

1. Chithunzi cha Immersion Gold Board yokhala ndi Poor Oxidation:

2. Kufotokozera za Kumizidwa kwa Golide Plate Oxidation:
The makutidwe ndi okosijeni wa golide-mizedwe dera bolodi wa dera wopanga bolodi ndi kuti pamwamba pa golide zaipitsidwa ndi zosafunika, ndi zosafunika zomangika pamwamba golide ndi oxidized ndi discolored, zomwe zimabweretsa makutidwe ndi okosijeni wa pamwamba golide kuti ife. nthawi zambiri kuyimba.M'malo mwake, mawu akuti golide pamwamba pa okosijeni siwolondola.Golide ndi chitsulo chosagwira ntchito ndipo sadzakhala oxidized pansi pazikhalidwe zabwino.Zonyansa zomwe zimayikidwa pamwamba pa golide monga ma ion amkuwa, ma nickel ions, tizilombo tating'onoting'ono, ndi zina zambiri.Zinthu.

3. Kupyolera mu kuyang'ana, akupezeka kuti makutidwe ndi okosijeni wa kumizidwa golide dera bolodi makamaka ali ndi makhalidwe awa:
1. Kugwira ntchito molakwika kumapangitsa kuti zonyansa zimamatire pamwamba pa golide, monga: kuvala magolovesi onyansa, machira a zala okhudzana ndi golide, mbale ya golide yokhudzana ndi zolembera zonyansa, mbale zothandizira, ndi zina zotero;Mtundu uwu wa okosijeni ndi waukulu ndipo ukhoza kuchitika nthawi imodzi Pa mapepala angapo oyandikana nawo, maonekedwe amawoneka opepuka komanso osavuta kuyeretsa;
2. Bowo la theka la pulagi, makutidwe ndi okosijeni ang'onoang'ono pafupi ndi dzenje;Mtundu uwu wa okosijeni umachitika chifukwa cha madzi awo omwe ali mu dzenje kapena dzenje la pulagi kuti asatsukidwe kapena mpweya wotsalira wamadzi mu dzenje, madzi awo amafalikira pang'onopang'ono pakhoma la dzenje panthawi yosungiramo zinthu zomalizidwa. amapangidwa pamwamba pa golidi;
3. Kusakwanira kwa madzi kumapangitsa kuti zonyansa za m'madzi ziwonongeke pamwamba pa golide, monga: kutsuka pambuyo pomira golide, kutsuka ndi wothira mbale yomalizidwa, malo otsekemera oterewa ndi ochepa, nthawi zambiri amawonekera m'makona a mapepala a munthu aliyense. zowonekera kwambiri Madzi madontho;mbale ya golide ikatsukidwa ndi madzi, padzakhala madontho a madzi pa pad.Ngati madziwo ali ndi zonyansa zambiri, madontho amadzi amasungunuka mwachangu ndikuchepera mpaka kumakona pomwe kutentha kwa mbale kukukulira.Madzi atatha, zonyansazo zidzalimba Pangodya za pad, zowonongeka zazikulu zotsuka pambuyo pa kumizidwa mu golidi ndikutsuka muzitsulo zomalizidwa ndi tizilombo toyambitsa matenda.Makamaka thanki yokhala ndi madzi a DI ndiyoyenera kufalitsa bowa.Njira yabwino yoyendera ndikungogwira pamanja.Onani ngati pali poterera pakona yakufa ya khoma la thanki.Ngati alipo, ndiye kuti madziwo aipitsidwa;
4. Kupenda bolodi lobwerera kwa kasitomala, apeza kuti pamwamba pa golide ndi wocheperako, nickel pamwamba ndi dzimbiri pang'ono, ndipo malo oxidation ali ndi abnormal element Cu.Chinthu chamkuwa ichi chimakonda kwambiri chifukwa cha kusachulukira kwa golidi ndi faifi tambala komanso kusamuka kwa ayoni amkuwa.Mtundu uwu wa okosijeni ukachotsedwa, umakulabe, ndipo pamakhala chiopsezo cha re-oxidation.
