Ndi kusintha kwachangu kwa moyo wamakono wamakono womwe umafunikira njira zina zowonjezera zomwe zimakulitsa magwiridwe antchito a matabwa anu ozungulira potengera zomwe akufuna, kapena kuthandizira ndi njira zamagawo osiyanasiyana kuti muchepetse ntchito ndikuwongolera magwiridwe antchito, ANKE PCB ikudzipereka. kukweza chatekinoloje yatsopano kuti ikwaniritse zofuna za kasitomala nthawi zonse.
Cholumikizira cha m'mphepete chikukulira chala chagolide
Cholumikizira cholumikizira m'mphepete chomwe chimagwiritsidwa ntchito mu zala zagolide pama board okhala ndi golide kapena matabwa a ENIG, ndiko kudula kapena kupanga cholumikizira cham'mphepete pamakona ena.Zolumikizira zilizonse za beveled PCI kapena zina zimapangitsa kuti bolodi ikhale yosavuta kulowa mu cholumikizira.Edge Connector bevelling ndi gawo mu dongosolo lomwe muyenera kusankha ndikuwona njirayi ikafunika.
Kusindikiza kwa carbon
Kusindikiza kwa kaboni kumapangidwa ndi inki ya kaboni ndipo kumatha kugwiritsidwa ntchito polumikizira kiyibodi, kulumikizana ndi LCD ndi ma jumper.Kusindikiza kumachitidwa ndi conductive inki ya carbon.
Zinthu za carbon ziyenera kukana kutenthedwa kapena HAL.
Kutentha kwamadzi kapena Carbon m'lifupi sikungachepetse pansi pa 75 % ya mtengo womwewo.
Nthawi zina chigoba cha peelable chimakhala chofunikira kuti muteteze ku ma fluxes omwe amagwiritsidwa ntchito.
Mask opangidwa ndi solder
Peelable soldermask The peelable resist layer imagwiritsidwa ntchito kuphimba madera omwe sayenera kugulitsidwa panthawi ya solder wave.Wosanjikiza wosinthikawu amatha kuchotsedwa mosavuta kuti asiya mapepala, mabowo ndi malo ogulitsidwa bwino kuti azitha kusonkhana komanso kuyika gawo / cholumikizira.
Akhungu & kukwiriridwa vais
Kodi Blind Via ndi chiyani?
Mu akhungu kudzera, ndi kudzera zikugwirizana wosanjikiza kunja kwa zigawo chimodzi kapena zingapo zamkati za PCB ndipo ndi udindo interconnection pakati wosanjikiza pamwamba ndi zigawo zamkati.
Kodi Kukwiriridwa Ndi Chiyani?
M'manda kudzera, zigawo zamkati zokha za bolodi zimagwirizanitsidwa ndi via."Imakwiriridwa" mkati mwa bolodi ndipo sichikuwoneka kuchokera kunja.
Akhungu ndi m'manda vias makamaka opindulitsa HDI matabwa chifukwa konza kachulukidwe bolodi popanda kuwonjezera bolodi kukula kapena chiwerengero cha zigawo gulu chofunika.
Momwe mungapangire ma akhungu & okwiriridwa vias
Nthawi zambiri Sitigwiritsa ntchito kubowola laser mozama popanga ma vias akhungu ndi okwiriridwa.Choyamba, timabowola chikhomo chimodzi kapena zingapo ndikuyika m'mabowowo.Kenako timapanga ndikusindikiza stack.Izi zitha kubwerezedwa kangapo.
Izi zikutanthauza:
1. A Via nthawi zonse amayenera kudula magawo angapo amkuwa.
2. A Via sangathe kutha pamwamba pa pachimake
3. A Via sangayambe pansi pa pachimake
4. Ma Vias akhungu kapena okwiriridwa sangayambe kapena kutha mkati kapena kumapeto kwa Wakhungu/Wokwiriridwa wina kudzera pokhapokha ngati wina atatsekeredwa mkati mwa mzake (izi zidzawonjezera mtengo wowonjezera ngati wowonjezera wosindikizira akufunika).
Kuwongolera kwa Impedans
Kuwongolera kwa Impedans kwakhala chimodzi mwazinthu zofunikira komanso zovuta zazikulu pamapangidwe apamwamba kwambiri a pcb.
M'mapulogalamu apamwamba kwambiri, kuwongolera koyendetsedwa kumatithandiza kuwonetsetsa kuti ma siginecha sakuwonongeka akamayenda mozungulira PCB.
Kukaniza ndi kukhudzidwa kwa dera lamagetsi kumakhudza kwambiri magwiridwe antchito, chifukwa njira zenizeni ziyenera kumalizidwa pamaso pa ena kuti zitsimikizire kugwira ntchito moyenera.
Kwenikweni, kulepheretsa kolamuliridwa ndiko kufananiza kwa zinthu zapansi panthaka yokhala ndi miyeso yolondolera ndi malo kuwonetsetsa kuti kutsekeka kwa chizindikirocho kuli mkati mwamtengo wina wake.
