Electroplated hole sealing ndi njira yodziwika bwino yopanga ma board board omwe amagwiritsidwa ntchito kudzaza ndi kusindikiza pamabowo (kupyolera m'mabowo) kuti apititse patsogolo mphamvu zamagetsi ndi chitetezo. M'magawo osindikizira a board board, dzenje lodutsa ndi njira yomwe imagwiritsidwa ntchito kulumikiza zigawo zosiyanasiyana. Cholinga cha kusindikiza kwa electroplating ndikupanga khoma lamkati la dzenje lodzaza ndi zinthu zopangira zinthu popanga chitsulo kapena ma conductive zinthu mkati mwa dzenje, potero kumapangitsa kuti magetsi aziyenda bwino komanso kusindikiza bwino.
1.the circuit board electroplating kusindikiza ndondomeko yabweretsa ubwino wambiri pakupanga mankhwala:
a) Kupititsa patsogolo kudalirika kwa dera: njira yosindikizira yosindikiza ma electroplating imatha kutseka mabowo ndikuletsa magetsi afupikitsa pakati pa zigawo zachitsulo pa bolodi yozungulira. Izi zimathandiza kukonza kudalirika ndi kukhazikika kwa bolodi ndikuchepetsa chiopsezo cha kulephera kwa dera komanso kuwonongeka
b) Kupititsa patsogolo kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake ka magetsi. Bowo lodzazira la Electroplate litha kupereka kulumikizana kokhazikika komanso kodalirika kwa dera, kuchepetsa vuto la kutayika kwa ma sign ndi kusagwirizana kwa impedance, motero kumapangitsa kuti magwiridwe antchito azigwira ntchito komanso zokolola.
c) Sinthani mtundu wowotcherera: njira yosindikizira yosindikiza ma electroplating imathanso kupititsa patsogolo mtundu wa kuwotcherera. Kusindikiza kungathe kupanga malo osalala, osalala mkati mwa dzenje, kupereka maziko abwino opangira kuwotcherera. Izi zitha kusintha kudalirika ndi mphamvu zowotcherera ndikuchepetsa kupezeka kwa zolakwika zowotcherera komanso zovuta zowotcherera.
d) Limbikitsani mphamvu zamakina: Njira yosindikizira ma electroplating imatha kupititsa patsogolo mphamvu zamakina komanso kulimba kwa bolodi yozungulira. Kudzaza mabowo kumatha kukulitsa makulidwe ndi kulimba kwa bolodi lozungulira, kuwongolera kukana kwake kupindika ndi kugwedezeka, komanso kuchepetsa chiwopsezo cha kuwonongeka kwamakina ndikusweka pakagwiritsidwa ntchito.
e) Kusonkhana kosavuta ndi unsembe: dera bolodi electroplating kusindikiza ndondomeko akhoza kupanga msonkhano ndi unsembe ndondomeko yabwino ndi kothandiza. Kudzaza mabowo kumapereka malo okhazikika komanso malo olumikizirana, kupangitsa kukhazikitsa kwa msonkhano kukhala kosavuta komanso kolondola. Kuphatikiza apo, kusindikiza dzenje la electroplated kumapereka chitetezo chabwino komanso kumachepetsa kuwonongeka ndi kutayika kwa zigawo panthawi ya unsembe.
Nthawi zambiri, njira yosindikizira yosindikiza ma electroplating imatha kusintha kudalirika kwa dera, kukulitsa magwiridwe antchito a dera, kuwongolera mtundu wa kuwotcherera, kulimbitsa mphamvu zamakina, ndikuthandizira msonkhano ndi unsembe. Ubwinowu ukhoza kupititsa patsogolo kwambiri khalidwe la mankhwala ndi kudalirika, pamene kuchepetsa chiopsezo ndi mtengo pakupanga
2.Ngakhale njira yosindikizira yosindikiza ma electroplating ili ndi zabwino zambiri, palinso zoopsa zina kapena zolakwika, kuphatikiza izi:
f) Kukwera kwamitengo: Njira yotsekera dzenje lotsekera imafuna njira zowonjezera ndi zida, monga zodzaza ndi mankhwala omwe amagwiritsidwa ntchito popanga. Izi zikhoza kuonjezera ndalama zopangira zinthu komanso zimakhudza chuma chonse cha malonda
g) Kudalirika kwanthawi yayitali: Ngakhale njira yosindikizira ma electroplating imatha kusintha kudalirika kwa bolodi ladera, pakagwiritsidwe ntchito kwanthawi yayitali komanso kusintha kwa chilengedwe, zinthu zodzaza ndi zokutira zimatha kukhudzidwa ndi zinthu monga kukulitsa kwamafuta ndi kuzizira. contraction, chinyezi, dzimbiri ndi zina zotero. Izi zitha kupangitsa kuti zinthu zotayirira, kugwa, kapena kuwonongeka kwa plating, kuchepetsa kudalirika kwa bolodi.
h) 3Njira zovuta: The dera bolodi electroplating kusindikiza ndondomeko ndi zovuta kuposa ndondomeko ochiritsira. Zimaphatikizapo kulamulira masitepe ambiri ndi magawo monga kukonzekera dzenje, kudzaza zinthu zosankhidwa ndi zomangamanga, kuwongolera njira ya electroplating, ndi zina zotero. Izi zingafunike luso lapamwamba la ndondomeko ndi zipangizo kuti zitsimikizire kuti ndondomekoyi ndi yolondola komanso yokhazikika.
i) Wonjezerani ndondomekoyi: onjezani ndondomeko yosindikiza, ndikuwonjezera filimu yotsekera pamabowo okulirapo kuti muwonetsetse kuti kusindikiza kumatheka. Pambuyo kusindikiza dzenje, m'pofunika fosholo mkuwa, akupera, kupukuta ndi njira zina kuonetsetsa flatness wa kusindikiza pamwamba.
j) Kukhudza chilengedwe: Mankhwala omwe amagwiritsidwa ntchito posindikiza ma electroplating akhoza kukhala ndi zotsatira zina pa chilengedwe. Mwachitsanzo, zinyalala zamadzi zonyansa ndi zamadzimadzi zitha kupangidwa panthawi ya electroplating, zomwe zimafunikira chithandizo choyenera ndi chithandizo. Kuonjezera apo, pakhoza kukhala zigawo zowononga zachilengedwe muzinthu zodzaza zomwe ziyenera kuyang'aniridwa ndi kutayidwa bwino.
Poganizira njira yosindikizira ma electroplating board board, ndikofunikira kuganizira mozama zowopsa kapena zofooka zomwe zingachitike, ndikuyesa zabwino ndi zoyipa malinga ndi zosowa zenizeni ndi zochitika zogwiritsa ntchito. Pokhazikitsa ndondomekoyi, njira zoyenera zoyendetsera khalidwe ndi kayendetsedwe ka chilengedwe ndizofunikira kuti zitsimikizire zotsatira zabwino za ndondomeko ndi kudalirika kwa mankhwala.
3.Miyezo yovomerezeka
Malinga ndi muyezo: IPC-600-J3.3.20: Electroplated copper plug microconduction (wakhungu ndi kukwiriridwa)
Sag and bulge: Zofunikira za bulge (bump) ndi kukhumudwa (dzenje) lakhungu lakhungu kudzera pabowo zimatsimikiziridwa ndi maphwando omwe amaperekedwa ndikufunidwa kudzera pazokambirana, ndipo palibe chofunikira pakuphulika ndi kukhumudwa kwa micro -kupyolera mu dzenje lamkuwa. Zolemba zenizeni zogulira makasitomala kapena miyezo yamakasitomala ngati maziko a chiweruzo.
