1. PCB kudzera mu dzenje plating
Pali njira zambiri zopangira plating yomwe imakwaniritsa zofunikira pakhoma la dzenje la gawo lapansi. Izi zimatchedwa kutsegula khoma m'mafakitale. Opanga ma board a PCB amagwiritsa ntchito akasinja angapo osungira apakati popanga. Tanki iliyonse yosungiramo thanki ili ndi zofunikira zake zowongolera ndi kukonza. Kupyolera mu-bowo electroplating ndiye njira yofunikira yopangira pobowola. Chobowolacho chikabowola pachojambula chamkuwa ndi gawo lapansi lomwe lili pansipa, kutentha komwe kumapangidwa kumasungunula utomoni wotsekera womwe umapanga maziko a magawo ambiri, utomoni wosungunuka ndi zidutswa zina zobowola Zimayikidwa mozungulira dzenje ndikukutidwa pa dzenje lomwe langowonekera kumene. khoma mu zojambulazo zamkuwa, zomwe kwenikweni zimakhala zovulaza kumtunda wotsatira.
The wosungunuka utomoni adzasiyanso wosanjikiza wotentha olamulira pa dzenje khoma la gawo lapansi, zomwe zimasonyeza osauka kumamatira ambiri activators, zomwe zimafuna chitukuko cha kalasi ya njira zofanana ndi kuchotsa banga ndi etchback umagwirira. Njira imodzi yomwe ili yoyenera kwambiri pazithunzi za matabwa osindikizira ndi kugwiritsa ntchito inki yotsika kwambiri yamakasitomala kuti apange zokutira zomatira komanso zochititsa chidwi kwambiri pakhoma lamkati la aliyense kudutsa dzenje. Mwa njira iyi, palibe chifukwa chogwiritsira ntchito njira zambiri zothandizira mankhwala, sitepe imodzi yokha yogwiritsira ntchito, yotsatiridwa ndi kuchiritsa matenthedwe, ikhoza kupanga ❖ kuyanika mosalekeza mkati mwa makoma onse a dzenje, ikhoza kupangidwa mwachindunji popanda chithandizo china. Inkiyi ndi chinthu chopangidwa ndi utomoni chomwe chimamatira mwamphamvu ndipo chimatha kumangika mosavuta ku makoma ambiri opukutidwa ndi thermally, motero amachotsa njira yobwerera.
2. Reel kugwirizana mtundu kusankha plating
Zikhomo ndi mapini azinthu zamagetsi, monga zolumikizira, mabwalo ophatikizika, ma transistors, ndi ma board osinthika a FPCB, onse amakutidwa kuti apeze kukana kwabwino komanso kukana dzimbiri. Njira yopangira ma electroplating iyi imatha kukhala yamanja kapena yodziwikiratu, ndipo ndiyokwera mtengo kwambiri kusankha pini iliyonse payekhapayekha, kotero kuwotcherera kwa misa kuyenera kugwiritsidwa ntchito. Nthawi zambiri, malekezero awiri a zitsulo zojambulazo adagulung'undisa ku makulidwe ofunikira amakhomeredwa, kutsukidwa ndi njira zamakina kapena zamakina, kenako amasankhidwa ngati faifi tambala, golide, siliva, rhodium, batani kapena tini-nickel alloy, aloyi yamkuwa-nickel, Nickel. -kutsogolera aloyi, etc. kwa plating mosalekeza. Mu njira ya electroplating yosankha plating, choyamba, filimu yotsutsa imakutidwa pambali ya chitsulo chachitsulo chamkuwa chomwe sichiyenera kupakidwa, ndipo gawo lokhalo losankhidwa lamkuwa ndilokutidwa.
3. Kupaka zala
Chitsulo chosowa chimafunika kukutidwa pa bolodi m'mphepete cholumikizira, m'mphepete mwa bolodi lotuluka kapena chala chagolide kuti muchepetse kukana komanso kukana kuvala kwambiri. Njira imeneyi imatchedwa plating ya chala kapena plating part plating. Golide nthawi zambiri amakutidwa pamalumikizidwe otuluka m'mphepete mwa cholumikizira cha nickel chamkati. Chala chagolide kapena mbali yotuluka m'mphepete mwa bolodi imagwiritsa ntchito ukadaulo wamanja kapena wodziwikiratu. Pakadali pano, plating yagolide pa pulagi yolumikizirana kapena chala chagolide chakutidwa ndi agogo ndi lead, mabatani opukutidwa m'malo mwake.
Ndondomekoyi ili motere:

1. Chotsani zokutira kuti muchotse malata kapena zokutira pazitsulo zotulukira.
2. Muzimutsuka ndi madzi ochapira.
3. Tsukani ndi abrasives.
4. Kutsegula kumamizidwa mu 10% sulfuric acid.
5. Kukhuthala kwa nickel plating pazolumikizana zotuluka ndi 4-5μm.
6. Sambani ndi kuchotsa mchere madzi.
7. Chithandizo cha njira yolowera golide.
8. Kupaka golide.
9. Kuyeretsa.
10. Kuyanika.
4. Kupaka burashi
Ndi njira ya electrodeposition, ndipo si zigawo zonse zomwe zimamizidwa mu electrolyte panthawi ya electroplating. Mu njira iyi ya electroplating, malo ochepa okha ndi omwe amapangidwa ndi electroplated, ndipo alibe mphamvu pa ena onse. Nthawi zambiri, zitsulo zosowa zimakutidwa pazigawo zosankhidwa za bolodi losindikizidwa, monga madera monga zolumikizira m'mphepete mwa board. Kupaka burashi kumagwiritsidwa ntchito nthawi zambiri pokonza matabwa a zinyalala m'masitolo ogulitsa pakompyuta. Manga anode yapadera (anode yomwe ili yosagwira ntchito, monga graphite) muzinthu zoyamwa (thonje swab) ndikuigwiritsa ntchito kubweretsa yankho lopaka pamalo pomwe plating ikufunika.
Malingaliro a kampani Fastline Circuits Co., Ltd ndi akatswiri: PCB dera kupanga bolodi wopanga, kukupatsani: PCB proofing, mtanda dongosolo bolodi, 1-34 wosanjikiza PCB bolodi, mkulu TG bolodi, impedance bolodi, HDI bolodi, Rogers bolodi, Kupanga ndi kupanga matabwa PCB dera zosiyanasiyana njira ndi zida monga matabwa a microwave, matabwa a ma radio frequency, ma radar board, matabwa a mkuwa wandiweyani, etc.
