Kune kudzokorora kuvaka, batanidza chimiro chebvunzo neSKU chaiyo kuitira kuti huwandu hwenharembozha, ndangariro kana kamera dzisaedzwe zvichienderana nemaitiro asina kunaka.
Bhodhi guru repiritsi rakatetepa rinowanzo sanganisa zvikamu zvakapfava zvine FPC connectors dzisina kusimba uye mipendero yebhodhi yakaratidzwa ne mechanically. Dhizaini yekuvhura kwestencil, rutsigiro rwebhodhi, kunyatsoiswa kwayo uye reflow profile zvinofanira kuverengerwa musanganiswa uyu. Majoini e connector anotaridzika seanogamuchirwa pamberi pe enclosure assembly anogona kutadza gare gare kana divi rekuisa tambo kana mutoro weimba usina kufungwa nezvawo, saka kuongorora kwekutanga kunofanira kusanganisira mechanic mating kana zvichibvira.
Bvunzo inoshanda inofanira kutevedzera magadzirirwo echigadzirwa kwete chekisheni yePCBA. Kutangisa display, kutaurirana kwekubata, mabhazi ekamera, kukanganiswa kwemasensa, kuchaja, USB, wireless uye odhiyo zvinogona kuda zvigadziriso zvakasiyana kana software. Kazhinji zvinobudirira kutsanangura bvunzo pfupi yekugadzira inobata zvikanganiso zvekuunganidza wobva wasiya kusimbiswa kwechigadzirwa chose kuinjiniya. Chinhu chikuru ndechekutevera: kudzokorora bhodhi rekodhi, firmware, vhezheni yemidziyo uye mhedzisiro yebvunzo saka matambudziko ekubatanidzwa kwenguva pfupi anogona kuenderana nemamiriro chaiwo ekuvaka.
8. Zvinodiwa zveKutsvaga uye RFQ zveMapurogiramu ePCB eTablet Computer
Chiratidzo chePCB cheTablet Computer chinofanira kuratidza kugadziriswa kwehardware, sarudzo yekubatanidza yakaiswa, display/touch interface, bhatiri rinobatanidza, stack-up uye chero zvinodiwa ne controlled-impedance. Zvinotsiva zvikamu zvinoda kutarisirwa zvakanyanya kana zvikamu zvichishanda ne firmware, RF performance, connector fit kana power behavior.
mhedziso
Kugadzirwa kwePCB yemapiritsi kunonyanya kukonzera dambudziko guru rekubatanidza: michina mitete, simba rebhatiri, ma display/touch interconnects uye mabasa eRF akasarudzwa anofanira kudzorwa pamwe chete. Nzira chaiyo yekuunganidza nekusanganisa inofanira kutevedzera dhizaini yakaburitswa pane template ye "tablet board".
Mapiritsi eBOM ane zvikamu zvakawanda zvisingadiwi kana zvisingadzoreki: mapurosesa, memory/storage, maPMIC, ma display/touch controllers, makamera, RF devices, connectors uye power components. Kuenzana kwechimiro nepakeji hakuvimbisi firmware, nguva, thermal kana mechanical equivalence. Kutenga kunofanirwa kutsanangura vagadziri vanotenderwa uye dzimwe nzvimbo dzezvikamu izvi, nepo commodity passives inogona kushandisa AVL yakakura kana zvinodiwa nemagetsi zvichibvumidza.
RFQ yakasimba inoita kuti mutengo uenzane. Isa bhodhi rakaunganidzwa, ukobvu hwakapedzwa, ruzivo rweflex/rigid-flex kana rwukashandiswa, zvinodiwa zve controlled-impedance, nhamba dze display/touch part, bhatiri interface, wireless variant, zvinodiwa zveprogramming uye test coverage inotarisirwa. Highleap inogona kupatsanura kugadzirwa, kuwanikwa, kuunganidza, kuongorora, fixture uye kuyedza mari uye kuona kuti ndeapi madhiri anotungamira nguva. Izvi zvinogadzira nzira yakajeka kubva pa prototype kusvika pakudzokorora kugadzirwa kupfuura kutora kubva kuGerbers neBOM chete.
Poindi yekushandura yeRFQ
Kuti muwane PCB itsva yeTablet Computer , tumirai Gerber/ODB++ yakaburitswa, dhizaini yekugadzira, BOM, CPL, flex/mating drawings uye test expectations pamwe chete. Ongororo yacho inogona kutarisa pa thin-board yield, connector mechanics, BGA process risk uye variant control pachinzvimbo che generic tablet specifications.
