Ukwakheka kwe-stencil kanye nokugeleza kabusha kufanele kusalungiswa eduze kwamaphakheji aqediwe phansi, izixhumi ze-FPC nanoma yimaphi amadivayisi omsakazo avikelwe. I-assembler kufanele futhi ilawule izingxenye ezizwela umswakama futhi ivimbele ukuvuselelwa okungadingekile eduze kwezixhumi zesibonisi ezinezingqimba ezincane.
Ububanzi bokukhiqiza bunganikeza ukuhlanganiswa kwe-SMT kanye nokuhlolwa okuqondiwe. Amaphakheji afihliwe angabuyekezwa nge-X-ray uma echaziwe, kuyilapho izingxenye ezibonakalayo zifanelekela i-AOI. Ukusebenza kwamandla aphansi kusadinga ukuhlolwa kukagesi; ukuhlolwa okubonakalayo akukwazi ukuveza ugesi olindile ngokweqile noma ukulandelana kwamandla okungalungile.
Ukulawulwa kwezingxenye zamandla aphansi kubaluleke kakhulu ngesikhathi sokuthola amandla. Ama-regulator, ama-load switch, ama-pull resistors, ama-oscillator namadivayisi ememori angathonya ukuziphatha kwamandla okulala noma ukuvuka ngisho noma ukushintsha kuhambisana ngokusobala. Ngakho-ke i-BOM evunyiwe kufanele ihlukanise ukushintshana kwangempela ezingxenyeni ezidinga ukuqinisekiswa kobunjiniyela. Lena inkinga yokuthengwa kanye nekagesi, ngoba ukushintshana okungagunyaziwe kunganciphisa impilo yebhethri buthule ngaphandle kokudala ukwehluleka kwefektri ngokushesha.
Ukulawulwa kwenqubo yokuhlanganisa kufanele kubonise ingxube yama-IC anamandla aphansi, izixhumi ze-fine-pitch kanye nama-passive amancane. Ukuzwela komswakama, ivolumu yokunamathisela kanye nokuvezwa kokugeleza kabusha kungabaluleka kuma-processor, imemori kanye namadivayisi wamandla aqediwe phansi. Ukubuyekezwa kwengxenye yokuqala kufanele kuqinisekise wonke umuntu ongakhetha kukho ngoba i-pull-up eyengeziwe, isiteshi se-LED noma ingxenye yomsindo ingashintsha i-standby current ngisho noma ingavimbeli ukuqala.
Ukuhlanzeka kungabaluleka kakhulu kumasekethe anomoya ophansi kunasemikhiqizweni yedijithali eqinile. Izinsalela ze-Ionic noma ukungcola okuzungeze ama-node ane-impedance ephezulu kungadala ukuvuza noma ukuziphatha okungenasikhathi okuvela ngaphansi komswakama kuphela. Imfuneko yokuhlanzeka efanele incike ekuhlosweni komklamo nokuthembeka, kodwa kufanele icatshangelwe ngesikhathi sokuhlela inqubo esikhundleni sokucatshangelwa ngemva kokuvela kokwehluleka. I-AOI, i-X-ray eqondiwe kanye nokuhlolwa kokusebenza bese kuhlanganisa amakilasi ahlukene okukhubazeka; akukho okufanele kwethulwe njengokufaka esikhundleni esiphelele sabanye.
7. Ukuqinisekiswa Okusebenzayo Kokuvuselelwa Kwesibonisi, Ukushaja Nokuxhumana
Uhlelo lokuhlola i-e-reader oluwusizo luqinisekisa imisebenzi ethile yomkhiqizo kunokuhlola uhlu olujwayelekile lwe-elekthronikhi. Kuye ngomklamo kanye nezinto ezitholakalayo, lokhu kungafaka phakathi ukuhlela, ukuziphatha kokuvula, isibuyekezo sesibonisi, impendulo yokuthinta, ukulawula ukukhanya kwangaphambili , ukushaja, ukuxhumana kwe-USB, ukuxhumana okungenantambo kanye nokuhlolwa kokusetshenziswa kwamanje.
Ukuhlolwa kokusebenza kufanele kuphinde kukhiqize imisebenzi ebalulekile ekukhishweni komkhiqizo: ukuhlela, ukuvula, ukuqalisa ukubonisa, ukuvuselela ikhasi, ukutholwa kokushaja, ukuxhumana kwe-USB kanye nokuxhumeka okungenantambo lapho kufakwa khona. Ukuthinta, izinkinobho kanye nokukhanya kwangaphambili kungangezwa ngezinhlobo ezifaka zona. Ukuhlolwa kufanele futhi kuhlole izimo zamanje ezivunyelwene ngazo uma ukusebenza kwamandla aphansi kuyinto ebalulekile yokwamukelwa futhi i-fixture ingazilinganisa ngokuphindaphindiwe.
Ukuhlolwa kwesibonisi kufanele kufake ukuziphatha kwangempela kokubuyekezwa ngoba iphutha lesixhumi noma isizinda samandla kungenzeka lingabonakali esikrinini esingaguquki. Ukukhiqiza kungenza ukuhlolwa kokusebenza okuchazwe ngamakhasimende uma i-firmware edingekayo, izimpahla zokuhlola kanye nemikhawulo yokupasa/yokwehluleka inikezwa.
Ukuhlolwa kwesibonisi kudinga umkhawulo ocacile. Ifektri ye-PCBA ingaqinisekisa ukuthi i-electronics command the module iyavela nokuthi amaphethini alindelekile ayavela, kodwa i-ghosting, ukufana kwe-optical, ukufana kwe-front-light kanye nokuhlangenwe nakho kokufunda kokugcina kuthonywa yi-display module kanye ne-mechanical stack. Ukuhlukanisa ukuhlolwa kokusebenza kukagesi ne-final optical qualification kwenza isimangalo sokukhiqiza sibe yiqiniso kakhulu futhi kusiza ukuthengwa kuqhathaniswe izingcaphuno ngobubanzi obufanayo.
Ithuluzi eliwusizo lokusebenza kufanele liqinisekise ukulandelana kwemisebenzi ehlukanisa i-PCBA ye-e-reader: ukulawulwa kwamandla, ukuxhumana kokubonisa, isibuyekezo sesithombe, ukulala/ukuvuka, ukushaja kanye nanoma yimiphi imisebenzi yokuthinta/ukukhanya kwangaphambili/okungenantambo efakiwe. Ukuhlola okulula "kokuvula isikrini" kubuthakathaka ngoba i-flex yesibonisi ephindaphindayo noma isitimela samandla esingaphansi singadlula kanye futhi sehluleke ngesikhathi sokuvuselela okuphindaphindiwe. I-NPI inganquma ukuthi mangaki amaphethini wokuvuselela noma izinguquko zesimo ezidingekayo ukuze kubanjwe amaphutha okuhlanganisa ngaphandle kokwenza ukuhlolwa komugqa kube kude ngokungadingekile.
Ukulinganisa kwamanje kufanele kuchazwe ngendlela yakho yokuhlola. Umshini wokuvuselela osebenzayo, umshini wamanje ongasebenzi kanye nomshini wamanje olele kakhulu yizimo ezahlukene futhi akufanele kuhlanganiswe kube umkhawulo owodwa. Uma ikhasimende lidinga ukuhlolwa kwamanje kokukhiqiza, ukwakheka kwe-firmware, ukubambezeleka kokulinganisa kanye nezinto ezixhunyiwe kufanele kulungiswe. Lokhu kudala isango eliphindaphindwayo elivikela ukusebenza kwamandla aphansi ngenkathi kugwenywa ukwehluleka kwamanga okubangelwa isofthiwe engalawulwa noma umsebenzi wokubonisa.
8. Ukuthola Nokukhetha Abaphakeli Bokukhiqizwa Kwe-PCB Ye-E-Reader
Ukuze uthole i -E-Reader PCB RFQ, thola imojuli yokubonisa, izinketho zokuthinta/ukukhanya kwangaphambili, isikhombikubona sebhethri, ukucushwa okungenantambo, izingxenye ezivunyiwe kanye nemigomo yokuhlola. Lokhu kuvimbela i-assembler ukuthi iphathe ama-SKU amabili e-e-reader afanayo ngendlela efanayo nokwakhiwa kwe-elekthronikhi.
Isiphetho
Inselele enkulu yokukhiqiza kumfundi we-e ukugcina uhlelo olunamandla aphansi oluzungeze isibonisi se-ePaper. Okuqukethwe okunembile kufanele kugcizelele ukuziphatha okulindile, ukuhlanganiswa kwesibonisi, ukuphathwa kwebhethri and optional touch/front-light functions—not copy a tablet-computer PCB isifanekiso.
Ukunikezwa kokubonisa kuvame ukuba yisizinda sohlelo lokuthola ulwazi lwe-e-reader ngoba imojuli, ukwesekwa komshayeli kanye ne-firmware kuhlobene kakhulu. Ngaphambi kokuvuma ezinye izindlela, ukuthengwa kufanele kuqinisekise i-electrical pinout, ukulingana komshini, izidingo ze-waveform/configuration kanye nokutholakala kwesikhathi eside. Isixwayiso esifanayo sisebenza kuma-PMIC, amadivayisi angenantambo kanye nezingxenye zebhethri/zokushaja. Ukushintshaniswa kwezimpahla okungadingi ugesi kungaba banzi kuphela uma i-voltage, ukuvuza, i-coefficient yokushisa kanye nezinye izinhlaka ezifanele zihlala ngaphakathi kwemingcele yokuklama.
Ukuze uthole ikhotheshini, khomba ukuthi yimiphi imisebenzi efakiwe nokuthi yimiphi engekho ngamabomu. Faka izinombolo zezingxenye zemojuli yokubonisa nokuthinta, inketho yokukhanya kwangaphambili, isikhombikubona sebhethri, ukucushwa okungenantambo, i-stack-up, i-BOM/CPL, amafayela ohlelo kanye nemikhawulo yokuhlola. Lokho kuvumela i-Highleap ukuthi yakhe umzila onezindleko zokukhiqiza, ukuhlanganisa kanye nokuqinisekisa ukusebenza kwamandla aphansi. Kuphinde kuvimbele iphutha elivamile lokuphatha ama-SKU amabili e-e-reader njengokufana ngoba abelana nge-enclosure noma uhlaka lwebhodi.
Iphuzu lokuguqulwa kwe-RFQ
Ukuze uthole iphrojekthi entsha ye-E-Reader PCB , thumela imininingwane yemojula ye-ePaper kanye nolwazi lokufanisa nephakheji ye-PCB. I-Highleap ingabuyekeza ingozi yokuxhumanisa ukubonisa, izilawuli zokuhlanganisa amandla aphansi kanye nochungechunge lokuhlola ngaphambi kokuba kuhlanganiswe i-prototype lot.
