I-Highleap Electronics ikhiqiza imidwebo ye-PCB yamathebhulethi e-graphics akhishwe amakhasimende amathebhulethi epeni anezintambo, ama-pad okudweba angenantambo, amathebhulethi emfundo/asayina kanye namadivayisi okufaka angahlelwa. I-PCBA ingahlanganisa ama-elekthronikhi okuzwa i-digitizer, i-MCU, i-USB noma ukuxhumana okungenantambo, okhiye/ama-dial, ama-LED kanye nokuphathwa kwamandla; ubuchwepheshe bepeni, ikhono lokucindezela/ukuthambekela, ifomethi yombiko kanye nokuziphatha komshayeli we-host kusalokhu kuchazwa umklamo we-OEM kanye ne-firmware.

Izinhlobo Zomkhiqizo Wethebhulethi Yezithombe kanye Nezinhlobo Zehadiwe

Ithebhulethi yehluzo akuyona isakhiwo esisodwa sikagesi. Umndeni womkhiqizo usukela kumathebhulethi epeni le-USB elincane anebhodi elilodwa le-digitizer kuya kumathebhulethi angenantambo asebenza ngebhethri anomsakazo, okhiye, ama-dial kanye nezibonisi zendawo. Amanye asebenzisa ama-digitizer e-electromagnetic-resonance, kanti eminye imikhiqizo isebenzisa izakhiwo zokuzwa ezisebenzayo noma ezizimele. Imibhalo yokukhiqiza kumele ihlonze ubuchwepheshe kanye nesilawuli sangempela senzwa kunokuphatha "ukuzwela kwengcindezi" njengesici se-PCB.

Imindeni Yomkhiqizo Wethebhulethi Yezithombe

Amathebulethi ezithombe kanye nemikhiqizo ye-PCB yegundane ingase ixhumane njengamadivayisi e-interface yomuntu, kodwa izingozi zokukhiqiza zihlukile. I-RFQ yethebhulethi yezithombe kumele ilawule inzwa noma iphaneli ye-digitizer, i-front end yesilawuli/i-analog, ubuchwepheshe bepeni, isitaki sesembozo kanye ne-backback, izilawuli zezinqamuleli, i-interface ye-host kanye ne-firmware njengohlelo lokufaka oluhambisanayo.

Inzwa ye-Digitizer, i-Analog Front End kanye ne-Pen-Input Electronics

I-digitizer iyisistimu eyinhloko yokukhiqiza. Emiklamo ye-EMR, isakhiwo senzwa sidala futhi sithole insimu ye-electromagnetic; kwezinye izakhiwo, ama-electrode okuzwa kanye nesilawuli ziziphatha ngendlela ehlukile. Umhlinzeki we-PCB akufanele ashintshe i-geometry yenzwa, izindiza zokubhekisela, i-pinout yokuxhuma noma ukuhlunga kwe-analog ngaphandle kokuthi i-OEM ivuma ushintsho.

Izilawuli Zokukhiqiza Idijithali

• I-geometry yenzwa: gcina iphethini yekhoyili/i-electrode ekhishwe, ukugcinwa kanye nesakhiwo sesendlalelo. Izinguquko zobukhulu noma zethusi zingathinta ukufana kokuzwa ngisho nalapho ukuhlolwa okujwayelekile kokuqhubeka kudlula.
• Ingaphambili le-analog: gcina amandla omsindo ophansi, ukuhlunga, amanani ezingxenye kanye nokusekelwa kusukela kumklamo wereferensi okhishwe. Lawa masekethe azwela kakhulu ekushintsheni okungabuyekezwanga kunokufakwa kwezinkinobho okuvamile.
• Iwashi lomlawuli kanye ne-firmware: Ukuziphatha kokuskena kwe-digitizer kuncike kumlawuli kanye ne-firmware. Ukubuyekezwa kohlelo kumele kuxhunywe kusibuyekezo sehadiwe kanye nephaneli yesenzwa.
• Izimangalo zepeni: Ukusebenza okungenabhethri, amazinga okucindezela, ukuthambekela, ukujikeleza noma imisebenzi yerabha kuncike kubuchwepheshe kanye ne-firmware. Kufanele kuqinisekiswe kusukela ekucacisweni kwe-OEM kunokukopishwa kusuka emndenini wethebhulethi ohlukile.
• Ukusebenzisana kwesivikelo/kwesivikelo: Amapuleti ensimbi, amabhethri, izibonisi kanye nezintambo kungathonya ukuzwa. Ukufana kokugcina kanye nokunemba kudinga ukuqinisekiswa kwezinga lesistimu ngesitaki esihlosiwe semishini.

Uma umklamo uhlanganisa izizinda ze-analog nezedijithali ezibucayi, izinto ezicatshangelwayo zokukhiqiza i-PCB yesignali exubile ye-Highleap zibaluleke kakhulu kunemithetho ejwayelekile "ye-PCB enesivinini esikhulu".

Ukwakhiwa Kwethebhulethi Engenantambo ye-USB, i-Bluetooth kanye ne-2.4 GHz

Isixhumi esibonakalayo sethebhulethi yepeni singaba yi-USB, i-Bluetooth, isixhumanisi esingenantambo esizimele, noma inhlanganisela. Imininingwane ye-USB HID ichaza uhlaka olujwayelekile lwedivayisi yokufaka oluzichazayo, kodwa ithebhulethi ye-OEM ingadinga nemibiko ethile yomthengisi kanye nomshayeli. Ngokufanayo, ithebhulethi enamandla e-Bluetooth ingasebenzisa i-HID ngaphezu kwe-GATT kuphela uma i-firmware/iphrofayili ekhishwe yaklanywa ngaleyo ndlela.

Ukuxhumana kanye Nezinketho Zamandla

Kumadizayini angenantambo, ukucaciswa kwe-antenna, i-geometry yomhlabathi kanye nezingxenye ezifanayo kufanele kulandele ukwakheka kwe-RF okukhishwe. Ukwakhiwa kungasebenzisa izilawuli zokuklama ze-antenna ze-Bluetooth PCB kanye ne -PCB , kuyilapho ububanzi bomkhiqizo oqediwe, ukuhlala ndawonye kanye nesitifiketi somsakazo kusalokhu kuyizinto zokuqinisekiswa kwezinga lomkhiqizo.

Okhiye Abasheshayo, Ama-Dials, Ama-LED kanye Nokulawula Kwabasebenzisi Bemishini

Amaphilisi okudala avame ukuhluka ngezinkinobho ezisheshayo, imichilo yokuthinta, ama-dial ajikelezayo kanye nezinkomba. Lezi zingxenye zisebenza ngogesi ngesivinini esiphansi, kodwa ukubekezelela kwazo imishini kungadala inani elingalingani lezinkinga zokuhlola. Iswishi esebenza kahle ngogesi kodwa engeyi-0.4 mm phakathi nendawo ingazwakala ingalungile uma ihlanganiswe ngaphansi kwe-keycap.

Uhlu Lokuhlola Lokuhlanganiswa Kokulawula Komsebenzisi

• Ukuphakama kokushintsha kanye nokuhamba: fanisa i-mechanical stack kanye ne-keycap design evunyiwe.
• Isishumeki esijikelezayo: qinisekisa ukuphakama komgodi, indlela yokubopha/yokugcina kanye nokubalwa kwezinkomba esivivinyweni sokusebenza.
• I-strip yokuthinta noma indawo yokuthinta yesibili: gcina i-geometry yenzwa kanye nokuhlela isilawuli; qinisekisa ngohlelo lokusebenza lokuhlola ikhasimende.
• I-LED / isibonisi: hlola i-polarity, izimo zokukhanya kanye nokuqondaniswa kwepayipi lokukhanya; ungasebenzisi umbala/ukukhanya njengepharamitha yokufaka esikhundleni engalawulwa.
• Indawo yokuxhuma: Indawo yokuphuma ye-USB-C noma ikhebula kufanele ihlolwe ngokuhambisana nendawo ebiyelwe, hhayi nje kuphela ngokuhlolwa ngamehlo.

Laba bangabalungele ukubuyekezwa komklamo wokuhlanganisa ngaphambi kokuba amathuluzi aqandiswe, ngoba ukufinyelela ngomshini, ukulandelana kokugoqa kanye nokulingana kwe-enclosure ngokuvamile kungathuthukiswa ngaphandle kokushintsha ama-electronics e-digitizer.

Ukuhlolwa kwe-Digitizer, Umkhawulo Wokulinganisa kanye noLawulo lwe-NPI

Ukuhlolwa kokufaka ipeni kudinga okungaphezu "kokudlula" kukagesi. Ifektri ingaqinisekisa ihadiwe ekhishwe kanye ne-firmware ngokumelene negridi echazwe yikhasimende, kodwa akufanele isungule imininingwane yayo yokunemba. Uhlelo lwe-NPI olungcono kakhulu luhlukanisa ukuhlolwa kwe-PCBA ekulinganisweni kokugcina kwethebhulethi kanye nokuqinisekiswa kwesofthiwe yomsingathi.

Izendlalelo Zokuhlola Ukukhiqiza

1. Ugesi we-PCBA: ama-power rails, ama-short/open, izinhlelo kanye nezixhumi eziyisisekelo.
2. Impendulo ye-Digitizer: qinisekisa ukutholwa kwepeni kuzo zonke izindawo zokuhlola ezichaziwe noma ezindaweni usebenzisa ipeni elivunyiwe kanye nesofthiwe.
3. Izilawuli: qinisekisa izinkinobho, ukudayela, ama-LED nanoma yimuphi umucu wokuthinta nge-firmware yomkhiqizo.
4. Ukuxhumana: Imibiko ye-USB kanye/noma ukubhanqa okungenantambo, kuye nge-SKU.
5. Ibhethri/ukushaja: Ukuhlolwa kwesimo sokushaja kanye nokwamanje kwezinguqulo ezingenantambo ngokuya ngomklamo wamandla akhishwe.
6. Ukuqinisekiswa kwesistimu: amajika okucindezela/ukuthambekela, ukubambezeleka, ukunemba, ukusebenzisana kwesandla kanye nokuziphatha komshayeli kuhlala kuyizinto zokwamukelwa kwezinga lomkhiqizo we-OEM ngaphandle kokuthi kunikezwe imikhawulo ethile yokukhiqiza kanye nezinto ezifakiwe.

I-Highleap ingahlanganisa i-prototyping esheshayo kanye nomklamo wokubuyekezwa kokuhlolwa ngakho-ke ama-test pad, ukufinyelela kohlelo kanye nezinto zokufaka izinzwa endaweni enkulu kuhlelwe ngaphambi kokwakhiwa kokuhlolwa.

Indawo Enkulu Yenzwa, Ukuthamba kanye Nokwakhiwa Kwephaneli

Njengoba amaphilisi ehluzo eba makhulu, ibhodi lezinzwa lingaba nzima kakhulu ngokwemishini ngisho noma izinto zikagesi zihlala zishesha kancane. Ukugoba nokusonta, ukujiya okunamathelayo, ukuthamba kwepuleti elingemuva kanye ne-torque yesikulufu kungashintsha ibanga phakathi kwepeni kanye nesakhiwo sokuzwa. Umdwebo wokukhiqiza kufanele ucacise i-mechanical stack kanye nokuthamba kwebhodi/inhlangano okwamukelekayo lapho kubalulekile khona ukuzwa; umthengisi we-PCB akufanele acabange ukuthi imikhawulo ejwayelekile yokugoba/ukusonta yanele ngokuzenzakalelayo ku-digitizer enkulu.

• Ukusekelwa kwephaneli yenzwa: sebenzisa isibambo esikhishwe, ipuleti noma isekelo lokuvala ukuze inzwa ingaguquguquki ngaphansi kwengcindezi yokubhala.
• I-torque ye-Fastener: i-torque eningi noma engalingani ingagoba ibhodi elikhulu noma iguqule isikhala endaweni yokubhala.
• Ingcina kanye ne-foam: ukujiya kanye nokucindezelwa kuyimingcele yokusebenza kwemishini lapho kusungula isikhala senzwa esisuka kusimbozo.
• Ukucindezeleka kwesixhumi: Amathebulethi amakhulu avame ukubeka izixhumi ze-USB noma ezigobile eduze komphetho; umthwalo wekhebula akufanele uphazamise indiza yesensa.
• Indlela ye-ESD: Izindawo zokubhala eziveziwe kanye nezixhumi eziseceleni kungadala izindlela zokukhipha izinto okufanele zilandele isu lokuvikela elikhishwe kanye ne-chassis.

Ngakho-ke ibhodi elibukeka lilula ngogesi lingadinga ukukhiqizwa kwe-PCB okuqinile ngokucophelela kanye nokulawulwa kokuhlanganiswa kwe-ESD . Isihloko sokuqala kufanele sihlolwe epuletini lokugcina elingemuva kanye nesembozo sangaphezulu, hhayi ebhentshini eliyisicaba kuphela.

Izindlela Zokwehluleka Kokukhiqiza Ngaphandle kokuthi “Ipeni Ayitholakali”

Uhlelo lokuhlola lwethebhulethi oluwusizo luhlukanisa ukwehluleka okuphelele kokukhubazeka kwendawo noma kokucushwa. Izindawo ezifile zingabonisa ukuvulwa kwenzwa, izinkinga zesixhumi noma izinguquko zejiyometri yendawo; ama-mirrored axes angabonisa ukuqondiswa kwesixhumi noma imephu ye-firmware; ama-coordinates angazinzile angavela emsindweni wamandla noma izinguquko zesitaki semishini; imibiko engalungile ye-express-key ingaba yinkinga ye-SKU/firmware. Ukuthwebula lezi zigaba zokwehluleka kulogi yokuhlola kunikeza ubunjiniyela indlela esheshayo eya embangweni wempande kunenkambu eyodwa yokudlula/yokwehluleka.

Ukuhlela Umugqa Womkhiqizo Osekelwe Kuzintambo, Ongenantambo kanye Nokwamukeli

Ipulatifomu yethebhulethi ingaklanywa njenge-USB kuphela, i-Bluetooth kuphela, engenantambo eyimfihlo enesamukeli se-USB, noma umkhiqizo wemodi embaxambili. Ukusebenzisa kabusha i-PCB eyodwa kuzo zonke izinguqulo kunganciphisa i-NRE kodwa kungashiya i-RF engasetshenziswanga noma isekethe yokushaja kuma-SKU ashibhile. Amabhodi ahlukene anganciphisa izindleko zamayunithi kodwa andise inani lokubuyekezwa kanye nenani lezinto ezifakiwe. Ukuthengwa kanye nobunjiniyela kufanele kunqume isu lepulatifomu ngaphambi kokwakhiwa kokuhlola, bese kubhalwa phansi izinketho ze-DNI, isithombe se-firmware kanye nokubhanqa kwezesekeli ze-SKU ngayinye.

Kumikhiqizo engenantambo eyimfihlo, isamukeli se-USB kufanele siphathwe njenge-PCBA yesibili yedivayisi yokufaka, hhayi nje isesekeli sokupakisha. Sidinga i-BOM yaso, ukwakheka kwe-antenna/USB, i-firmware, ubuwena kanye nokuhlolwa kokusebenza. Ithebhulethi ingadlula ekuzweleni kwepeni ngenkathi isamukeli esithunyelwe singahambisani, ngakho-ke i-firmware ehambisanayo kanye nokulawula ukubhanqa kufanele kube yingxenye yokupakishwa kokugcina lapho i-OEM idinga isamukeli.

Izinhlobo ze-Shortcut-Key kanye ne-Creative-Control

Amathebulethi ezithombe abelana ngezici eziningi ngezindawo zokulawula zokudala: amasongo ajikelezayo, imichilo yokuthinta, ama-dial omshini, amalebula e-OLED kanye namaqoqo okhiye angahlelwa. Lezo zengezo zandisa umndeni womkhiqizo futhi zingavumela amabhodi ahlukene noma imigqa egobile. Ngokombono wokukhiqiza, izinkinga ezibalulekile ukuphakama kokushintsha, i-eksisi yokuqopha ikhodi, ukugcinwa kwesixhumi sesibonisi/i-FPC, ukulungiswa kwe-LED/ipayipi yokukhanya kanye nokumapha kwe-firmware—hhayi igama lokumaketha lokulawula.

Okokufaka kwe-RFQ kanye nokulawula okuhlukile kwe-Graphics Tablet PCBA

I-RFQ yethebhulethi yehluzo kufanele ichaze ngokucacile uhlelo lwenzwa kanye nohlobo lomkhiqizo. “Ithebhulethi engenantambo engu-10 intshi” ayanele ngoba usayizi ofanayo ungasebenzisa ubuchwepheshe obuhlukene bepeni, izakhiwo zomsakazo, amabhethri kanye nezakhiwo zezihluthulelo. Lezi zinketho zithinta izindleko ze-PCB, ukutholakala kwezingxenye kanye nesikhathi sokuhlola.

Iphakheji ye-RFQ
