Ukwakhiwa kwe-PCB ye-NAS Enclosure kanye ne-Backplane Assembly

I-PCB ye-NAS enclosure kufanele ilingane ne-chassis yokugcina njengoba ixhumanisa ama-drive. Eplanini elingemuva elinama-multi-bay, isixhumi ngasinye se-drive kumele sihlangane nethreyi yaso endaweni ethile nokuphakama okucacisiwe. Ngakho-ke, uhlaka lwebhodi, izindawo zemigodi, ukulungiswa kwesixhumi kanye nekhwalithi yokunamathisela kuyingxenye yomsebenzi ofanayo wokukhiqiza—hhayi imininingwane ehlukile yemishini engeziwe ngemva kokwenziwa.

Leli khasi ligxile kumabhodi wesekethe afakwe ngaphakathi kwezindawo zokugcina isitoreji ze-NAS: ama-PCB e-drive backplane, amabhodi okusabalalisa amandla kanye nama-PCBA amancane okulawula noma amaphaneli angaphambili. I-Highleap Electronics inikeza ukwenziwa kwe-PCB ngokwezifiso, ukutholakala kwezingxenye okuvunyiwe kanye nokuhlanganiswa kwe-PCB kwalawa kanye namanye ama-elekthronikhi e-OEM. Ukuxhumeka kwe-SATA, SAS kanye ne-PCIe/NVMe kwenziwa ngokwedizayini ekhishwe yikhasimende; akuzona izinguqulo ezishintshashintshayo zebhodi le-NAS elijwayelekile.

Yimaphi Ama-PCB Assemblies Ahlala Ngaphakathi Kwe-NAS Enclosure?

Akukho ukwakheka kwebhodi lesekhethi elilodwa elabelwana ngalo yiyo yonke indawo yokugcina enamathiselwe kwinethiwekhi. Umkhiqizo omncane onezindawo ezimbili ungabeka izixhumi zedrayivu ebhodini lawo eliyinhloko. I-chassis enama-bay amane noma ayisishiyagalombili ingasebenzisa i-backplane ehlukile yokugcina, kuyilapho indawo enkulu ingangeza amandla ngamanye, ifeni noma amabhodi e-I/O angaphambili. Isethi yangempela ye-PCB ivela ekwakhiweni kwemishini kanye nogesi komkhiqizo wokugcina.

Ku -oda lokukhiqiza i-PCB ye-NAS enclosure eyenziwe ngokwezifiso , izinhlobo zokuhlanganisa ezifanele kakhulu yi-drive backplane ehambisana nama-HDD noma ama-SSD, ibhodi elisabalalisa amandla okushayela, kanye nama-PCBA asizayo ama-LED esimo, izinkinobho, izimpawu zokuba khona noma abalandeli. Ibhodi lomama lokulawula i-NAS liyi-assembly ehlukile ye-elekthronikhi futhi kufanele lihlonzwe ngokwehlukana uma liyingxenye ye-oda.

Izinsizakalo zokukhiqiza izinto zikagesi ze-Highleap zamabhodi wesekethe e-OEM zingamboza ama-PCB angenalutho ngamanye noma amasethi amabhodi anabantu abaningi. Ububanzi bokuhlanganisa bubonakala ngenombolo yengxenye yebhodi kanye nokubuyekezwa, ngakho-ke i-oda le-backplane alisho ukuthi ngephutha ukuthengwa kwama-drive, ibhodi leprosesa le-NAS noma ithuluzi lokugcina eliphelele.

Ama-Backplanes amaningi: I-Connector Pitch, i-Board Flatness kanye ne-Tray Fit

I-PCB ye-backplane ye-NAS enama-bay amane inezixhumi ze-SATA eziphindaphindwayo ezingaphezu kwezine. Isikhala ngasinye sokushayela singesephethini yomshini esungulwe yi-chassis kanye neziqondiso zayo zethreyi. Iphutha elincane ekuphakameni kwesixhumi, ukuphakama kwezihlalo noma indawo yokufaka ibhodi linganqwabelana kulo lonke umugqa, ikakhulukazi eplanini ende ye-backplane enama-drive amaningi.

Idatha yeshasi ifanele iphakheji yokwenziwa nokuhlanganiswa

Umdwebo okhishwe kufanele ucacise imigqa ephakathi yesixhumi, ukubekezelelana kwemigodi yokufakwa, indawo yebhodi, i-warp evunyelwe kanye nezindawo zokubhekisela ezisetshenziswa ukuvumelanisa i-backplane ne-chassis. Ukukhetha isixhumi kubalulekile futhi: izitayela eziqondile, ze-engeli yesokudla kanye ne-press-fit noma ezihlanganisiwe zinezinyathelo ezahlukene kanye nezidingo zokufaka. Izinto okufanele zenziwe kanye nokuhlanganiswa kwe-PCB ye-backplane kufanele zibuyekezwe maqondana nomklamo wangempela wesixhumi kanye ne-drive-tray, hhayi inani elilinganiselwe le-bay.

Kumabhodi agcwele abantu, ukuhlolwa kwenhlangano kungaqinisekisa izihlalo zesixhumi kanye nokulingana kanye ne-polarity, amajoyinti e-solder kanye nokugcinwa kwemishini. Uma i-OEM inikeza ithreyi yokubhekisela noma i-gauge yokulinganisa, ukuhlolwa kwengxenye yokuqala kungafaka zonke izikhundla ze-bay kunesixhumi esisodwa esiphakathi esisebenziseka kalula. Lokhu kuyindlela ewusizo yokuhlola isihloko sokuqala kwenhlangano ye-PCB ngaphambi kokukhiqizwa okuphindaphindiwe.

Amandla okushintshana ngokushisa awadalwa ngokufaka isixhumi esithile sodwa. Uchungechunge lokuxhumanisa isixhumi olucacisiwe, isekethe yokulawula amandla, ukwesekwa kwesilawuli kanye ne-firmware yomkhiqizo kumele konke kuhambisane nomklamo ovunyiwe. I-Highleap yakha futhi ihlanganise ihadiwe ekhishwe; noma yikuphi ukufaneleka kokujikeleza kwe-hot-plug noma amandla okufaka kufakwa kuphela uma kutholakala inqubo yokwamukela kanye nenqubo evunyelwene ngayo.

Ama-Backplane e-SATA, SAS kanye ne-NVMe adinga imininingwane ehlukene ye-PCB

Isixhumi sedrayivu kanye nesixhumi esibonakalayo kunquma ukuthi izimpawu zesitoreji zihamba kanjani ebhodini. I -SATA NAS backplane PCB isebenzisa izixhumanisi ze-SATA ezivunyiwe kanye nokucushwa kwesixhumi. I-SAS storage backplane ingeyesilawuli se-SAS esifanele kanye nendawo yokushayela. I -PCIe/NVMe NAS backplane ingasebenzisa izixhumi ezahlukene, amalungiselelo emizila kanye nezakhiwo zesivinini esiphezulu; ilebula ye-SSD iyodwa ayibonisi isixhumi esibonakalayo sikagesi.

Khipha ukwakhiwa kwesiteshi sangempela, hhayi isibalo esijwayelekile se-impedance

Idatha yokukhiqiza i-PCB kufanele ibone ukunqwabelana, ukuvinjelwa okudingekayo yi-interface, i-geometry yethusi, izindiza zokubhekisela, ukuguqulwa kwe-differential-pair kanye nanoma yiziphi izidingo zezinto ezihlobene nokulahlekelwa. Kumadizayini asekelwe ku-PCIe, umzila wemizila kanye nokushintsha okukhethwayo noma ama-retimer kuchazwa yisekethe. Kuma-backplane e-SATA noma e-SAS, ukuqhekeka kwesixhumi kanye nobude besiteshi kanye ne-geometry kusadingeka kulandele ukwakheka okuvunyelwe yi-OEM. Akulungile ukucabanga ukuthi yonke indawo ebiyelwe ye-NAS idinga i-HDI, i-RF laminate ebizayo noma inani lezingqimba ezihleliwe.

Izinhlobo zokukhiqiza nazo zithinta indawo. Uhlaka oluvamile lungakhishwa ngezixhumi ezahlukene, amadivayisi okuphatha noma imiphakathi ye-drive-bay. Idatha yokuhlanganisa idinga i-BOM evunyelwe yohlobo ngalunye, okuhlanganisa izikhundla zokungagcwalisi, izinombolo zezingxenye zesixhumi kanye ne-firmware noma izinto zokucushwa ezifanele. Lokhu kuvimbela i-SATA backplane kanye nomklamo we-PCIe/NVMe ukuthi kungaphathwa njengokushintshisana ngoba kusebenzisa isikhala esifanayo se-chassis.

Umhlangano we-PCB we-Drive Power, Fan kanye ne-Front-Panel

Ukusatshalaliswa kwamandla kuvame ukuhlanganiswa ne-drive backplane, yize ezinye izimbobo ze-NAS zisebenzisa i-PCB yamandla ehlukile. Umklamo okhishwe unquma ukuthi yimaphi ama-rails namadivayisi okuvikela adla i-bay ngayinye. Ukuziphatha kokuqala kwe-Multi-HDD kungahluka ku-all-SSD enclosure, ngakho-ke ukwehla kwamandla kagesi, ukwehla kwamandla kagesi kanye nokulandelana kwamandla kumele kuhlolwe ngokumelene nama-drive acacisiwe kanye nomklamo wesistimu, hhayi inani lomthwalo we-NAS elijwayelekile.

Kwi -PCB yokusatshalaliswa kwamandla ye-NAS , izilawuli zokukhiqiza zifaka ububanzi bethusi, ama-via anomoya ophezulu, izilinganiso zokuxhuma, izingxenye zokuvikela kanye namadivayisi okushintsha amandla avunyiwe. Indawo enendawo efanayo ingase ibe nokumelana okuhlukile, izici zamanje noma zokushisa. Izinto okufanele zicatshangelwe ngomklamo wokusatshalaliswa kwamandla e-PCB zibaluleke kakhulu lapho i-backplane ende inikeza izindawo eziningana ezinabantu abaningi.

Amabhodi amancane achaza nokuthi indawo ebiyelwe isebenza kanjani

Ukulawula abalandeli, i-LED yephaneli yangaphambili kanye namabhodi e-drive-status angase abe lula ngogesi, kodwa ukuqondiswa kwezixhumi kanye nokulingana kwemishini kubalulekile. Izintambo zazo kumele zifinyelele ezihlokweni ezifanele ngaphandle kokuvimbela amathreyi noma ukuhamba komoya. Ibhodi le-LED yesimo elifakwe ngemuva kwephaneli yangaphambili lidinga izikhundla zesikhombisi ezivunyiwe; ibhodi le-fan lidinga i-pinout yalo echaziwe, ukugcinwa kwesixhumi kanye nokucushwa.

Lapho i-oda lihlanganisa ukuhlanganiswa kwekhebula, ifeni noma i-chassis, ukuhlanganiswa kwebhokisi le-elekthronikhi kungaxoxwa ngakho njengesevisi echazwe ngokwehlukile. Ukuthola nokuhlanganisa i-PCB ye-turnkey ye-Highleap nakho kunikeza inketho yokuxhumanisa ukwenziwa kwebhodi okuvunyiwe, izingxenye ezithengiwe kanye nokukhiqizwa kwe-PCBA ngaphandle kokusho ukuthi kufakiwe uhlelo lokusebenza lwe-NAS oluqediwe.

Hlola Yonke I-Bay Ngaphambi Kokuthi i-NAS PCBA Ishiye Ukukhiqizwa

Iphethini yokuxhuma ephindaphindwayo yenza i-NAS backplane ifaneleke kakhulu kumarekhodi okukhiqiza aqondene nendawo. Esikhundleni somphumela owodwa we-PASS ongahlukanisiwe, i-fixture evunyelwene ngayo ingahlobanisa ukuhlolwa kukagesi ne-Bay 1, i-Bay 2 kanye nezindawo ezisele. Lokhu kungenza kube lula ukuthola isixhumi noma iphutha lokuhlangana futhi kuvimbele ukuhlolwa okuphumelelayo endaweni eyodwa ukuthi kume esikhundleni sezinye.

Ukuhlolwa kwebhodi okuhlukile kokuqinisekiswa kwesistimu ye-NAS okuphelele

Ububanzi bokuhlola bungafaka phakathi ukuqhubeka kwesixhumi kanye nama-shorts, ukuphuma kwamandla e-bay ngaphansi kwezimo ezichaziwe, izimpawu zokuba khona noma zesimo, kanye nokuhlolwa kwedatha okucacisiwe kusetshenziswa idrayivu yokubhekisela noma i-fixture evunyiwe. Amabhodi asebenzayo angadinga ukuqinisekiswa kwe-firmware noma i-management-interface. I-Highleap ingacaphuna ukuhlolwa kokusebenza kwe-PCBA okuchazwe amakhasimende lapho indlela, imishini yokuhlola kanye nemikhawulo yokwamukelwa kuvunyelwene.
