Ukukhiqizwa Nokuhlanganiswa Kwe-PCB Ye-Hard Drive Yangaphandle

I -PCB ye-hard drive ebiyelwe ingaphumelela ukuhlolwa kokutholwa kwe-USB ebhentshini kodwa yehluleke uma i-HDD yangempela ijikeleza. Ibhodi lesibili lingase libe namajoyinti aqinile kodwa lihluleke ukulingana ne-ebiyelwe ngoba isixhumi sayo se-SATA sihlala endaweni engalungile.

Ngakho-ke, kwi- PCB ebiyelwe ye-hard drive yangaphandle , ukulungela ukukhiqiza kuhilela okungaphezu kwesekethe yebhuloho elisebenzayo. Ibhodi kumele lifane nedrayivu ehlosiwe, isikhombimsebenzisi somsingathi, umthombo wamandla kanye nokuhlanganiswa komshini.

I-Highleap Electronics yakha futhi ihlanganise amabhodi ebhuloho akhishwe ngamakhasimende, ama-PCBA anamandla kanye nama-drive-interface assembly ngezinsizakalo zayo zokukhiqiza nge-elekthronikhi . Ukuthengwa kwezingxenye okuvunyiwe, i-SMT/through-hole assembly kanye nokuhlolwa okuchazwe ngamakhasimende kungafakwa ngokuya ngamafayela akhishwe kanye nobubanzi bokukhiqiza obuvunyelwene ngabo.

Yimaphi Ama-HDD Enclosure PCB Assemblies Owa-odayo?

Imikhiqizo emithathu ingachazwa njenge-HDD enclosure, kodwa ihlanganisa ama-oda ahlukene kakhulu okuhlanganisa ama-PCB:

• I-USB evalwe ephathekayo engu-2.5-intshi: Ngokuvamile i-PCBA yebhuloho elincane enesixhumi se-USB, isitho se-SATA kanye nesekethe yamandla endawo. Izidingo zayo zokukhiqiza zincike endaweni yesixhumi kanye nesabelomali samandla okusingatha.
• I-enclosure enamandla engu-3.5-intshi: Kungahlanganisa ibhuloho kanye nesigaba samandla ebhodini elilodwa noma kusetshenziswe i-PCBA yamandla ehlukile. I-RFQ kumele ibhekele i-adaptha yangaphandle, i-drive supply rails kanye nesixhumi se-DC-input.
• I-Dual-bay dock noma i-multi-bay DAS: Kungabandakanya ibhodi lokulawula, i-drive-connector/i-backplane PCB, ukusatshalaliswa kwamandla okwabiwe kanye ne-interface encane noma ibhodi lesikhombisi. Le misebenzi ingafakwa futhi emabhodini ambalwa.

Kumikhiqizo enamabhodi amaningi, umenzi udinga ubuningi kanye nokubuyekezwa kwe-PCBA ngayinye ngeyunithi eqediwe , kanye nanoma yiziphi izintambo noma ukuxhumana okufakiwe ku-oda. Ifayela le-Gerber lebhodi lebhuloho lodwa alichazi indawo ebiyelwe esebenza ngogesi ephelele.

Futhi hlukanisa ama-electronics avaliwe ne -PCB ye-hard drive exhunywe kwi-HDD uqobo. Ahlukene ngokuhlanganiswa okunemisebenzi ehlukene kanye nezidingo zokuthola ulwazi.

I-PCB ye-USB-to-SATA Bridge: Izingxenye kanye ne-Firmware Okumele Ihlale Ihambisana

Ibhuloho le-USB-to-SATA lilawula indlela idrayivu enamathiselwe ebonakala ngayo kumphathi. Amadivayisi amabili anezincazelo ezifanayo—noma ngisho nezinyathelo ezihambisanayo—angahluka ku-firmware, isitoreji sokucushwa kanye nemisebenzi esekelwayo.

Ngaphambi kokuhlanganisa okuphindaphindiwe, vala inombolo yengxenye yebhuloho, ezinye izindlela ezivunyiwe, i-firmware noma ifayela lokucushwa (uma kudingeka), kanye nokubuyekezwa kwehadiwe. Ukushintsha ibhuloho akuyona nje isinqumo sokuthenga izingxenye.

Ungasho ukusebenza kwebhuloho ngesokhethi ye-USB kuphela

Isitsha se-USB-C asiqinisekisi isivinini sedatha ye-USB, ukulethwa kwamandla e-USB noma ukwesekwa kwe-UASP. Lokho kuncike kusilawuli, ukwakheka kukagesi, i-firmware kanye nomsingathi. Kwi -PCB ye-USB-C hard drive enclosure , bhala phansi ukusetshenziswa kwe-USB kwangempela ngokuhlukile kohlobo lwesixhumi.

Okufanele kugcinwe kungaguquki ngesikhathi sokukhiqiza

• Idivayisi yebhuloho: isilawuli esivunyiwe kanye nanoma iyiphi inkumbulo yokucushwa.
• Ukuhlela: isithombe esikhishwe, ubunikazi be-USB obulindelekile kanye nenqubo yokuhlela, lapho kufanele khona.
• Izingxenye ezihlobene: ama-oscillator acacisiwe, imemori kanye namadivayisi esigaba samandla alawulwa yi ukutholakala kwezingxenye ze-elekthronikhi izimvume.
• Ukwamukela: ukubalwa okulindelekile kanye nokuziphatha kwesitoreji ngokusethwa kwereferensi okuvunyelwene ngakho.

Uma kuvela ubunikazi bedivayisi obungalungile noma ukuziphatha okulindelekile kwesitoreji kungabikho, ukucushwa kanye ne-firmware kufanele kuhlolwe ngaphambi kokushintsha izingxenye ezihlanganiswe kahle. Akuzona zonke izindawo ezivalekile ezidinga ukuhlelwa kwefektri.

Amabhodi Amandla Okufaka I-HDD: Hlola Idrayivu ku-Spin-Up

Ukuhlolwa kwe-voltage ngaphandle kwediski efakiwe akukwazi ukuthola ukuthi i-enclosure izoqala yini i-HDD yayo ehlosiwe. Ama-SATA drive amaningi angu-2.5-intshi asebenzisa i-5V supply futhi angase asebenze kusuka ku-USB lapho i-host kanye nekhebula kunganikeza amandla anele. Ama-SATA drive ajwayelekile angu-3.5-intshi avame ukudinga kokubili i-5V kanye ne-12V, ngokuvamile avela emthonjeni wangaphandle.

Uhlu lwe-supported-drive kanye nama-datasheet e-drive—hhayi igama lokumaketha le-enclosure—kunquma isabelomali samandla.

Linganisa ukuthi i-HDD ithola kuphi amandla

Kwibhodi lamandla le-HDD elingu-3.5-intshi , i-adaptha yokufaka, imephu yesitimela, izilinganiso zesixhumi, amadivayisi okuvikela kanye nomthwalo wokuqalisa kudingeka kuchazwe. Iphuzu lokulinganisa eliwusizo yi- drive connector ngesikhathi sokujikeleza , hhayi nje kuphela umphumela wokulawula ongenawo umthwalo.

I-DC jack engezansi, i-MOSFET engalungile noma indlela yethusi ephikisayo ingabangela ukusetha kabusha kuphela lapho injini iqala. Imikhiqizo ye-multi-bay idinga ukuthi ukuziphatha kokuqala okuhlosiwe ngesikhathi esisodwa noma okuhleliwe kuchazwe kunokuba kucatshangelwe.

Izimo ezimbili zokusebenza zidinga ukuhlolwa okuhlukile

• Isiqalo: Sebenzisa idrayivu yokubhekisela evunyiwe noma umthwalo ochaziwe ukuqinisekisa ukuziphatha kwesitimela okwamukelekayo ngenkathi i-HDD iqala futhi ibhuloho lihlala lisebenza.
• Ukufinyelela okuqhubekayo: Sebenzisa umthwalo womsebenzi wokufunda/ukubhala okuvunyelwene ngawo ukuze uhlole ukungazinzi okubonakala kuphela ngemva kokuba idrayivu isebenza.

Kumamodeli asebenzisa ibhasi, faka i-host ecacisiwe noma ukunikezwa kanye nekhebula. Kumamodeli asebenzisa amandla angaphandle, faka i-adaptha evunyiwe. Isikhathi sokuhlola kanye nemikhawulo yokupasa/yokwehluleka kumele kuvunyelwane ngayo ngaphambi kokuba kuqedwe ukulungiswa.

Ukulungiswa Kwesixhumi se-SATA: Ukuhlolwa Kwesihloko Sokuqala Okubalulekile

Isixhumi se-SATA esisongiwe kahle sisengabekwa ngendlela engafanele ngaphakathi kwe-enclosure. I-receptacle, imigodi yokufaka i-PCB kanye neziqondiso ze-housing kumele zibhekisele kuma-datam ahambisanayo omshini. Ngaphandle kwalokho, ukufaka i-HDD kungagoba i-PCB noma kulayishe isixhumi.

Hlola ibhodi elihlanganisiwe ngedrayivu ehlosiwe

Esihlokweni sokuqala, sebenzisa idrayivu kanye ne-enclosure—noma i-fixture emele—ukuqinisekisa:

• I-geometry yokuhlangana: Ukuphakama kwesixhumi se-SATA, i-axis yokufaka kanye nezihlalo zokushayela.
• Ukusekelwa kwebhodi: izinsika zokufaka, izikulufo kanye nezindawo zokugcina ezithwala imithwalo yemishini ehlosiwe.
• Ukususa: isikhala sezingxenye eziseduze, ikesi kanye nanoma yiziphi izintambo.
• Izingxenye ezivunyiwe: imidwebo yokuxhumanisa kanye nobukhulu, hhayi nje inani le-pin noma indawo yokuhamba.

Izixhumi ze -PCB ezivunyelwe amakhasimende zidinga ukuhlolwa okufanayo kokulingana lapho umhlinzeki eshintshwa.

I-PCB yesiteshi sokufaka i-HDD esilayisha phezulu nayo ihlukile esikhaleni esivaliwe: abasebenzisi bangafaka futhi basuse ama-drive ngokuphindaphindiwe. Isokhethi layo lidinga ukwesekwa okuchazwe ekwakhiweni komkhiqizo, kuyilapho ukugoqa kwesixhumi se-post-SMT kumele kugcine ukuhambisana.

Ama-Dual-Bay Docks, Iziteshi Zokuklonisa kanye nama-DAS PCBAs

Ukwengeza i-bay yesibili kushintsha ukwakheka kwesilawuli, ukusatshalaliswa kwamandla, ukuhlelwa kwesixhumi kanye nokuhlolwa kokukhiqiza. Kodwa ama-bay amabili awasho ngokuzenzakalelayo i-RAID noma i-cloning engaxhunyiwe ku-inthanethi; lezo zici zidinga isilawuli esifanele kanye ne-firmware.

Ukuze uthole i-dual-bay docking noma i-cloning PCBA

Khomba i-Bay A ne-Bay B kokubili enkambisweni yokudweba kanye nokuhlola. Uma isilawuli kanye nezisekelo zokushayela zihleli emabhodini ahlukene, ikhebula noma ukubuyekezwa kwe-backplane nakho kumele kulawulwe.

Lapho kunikezwa khona i-cloning engaxhunyiwe ku-inthanethi, ukuhlolwa kufanele kuqinisekise ukukhethwa komthombo/indawo kanye nokuziphatha kwesimo. Sebenzisa kuphela amadrayivu angasetshenziswa aqokiwe kunoma yimuphi umsebenzi obhala noma okopisha idatha.

Ukuze uthole indawo yokuvala i-DAS enama-bay amaningi

Uhlelo lwe-PCB olunezindawo eziningi ze-DAS enclosure lungaba ne-backplane ehlukene yokushayela, ukusatshalaliswa kwamandla, ukupholisa kanye nama-PCBA ephaneli langaphambili. Ibhodi ngalinye kufanele liphumelele ukuhlolwa kwalo okufanele, kulandelwe ukuhlolwa okuvunyelwene ngakho kwesethi yebhodi ehlanganisiwe kanye nayo yonke indlela yokushayela ehlosiwe.

I-DAS ne-NAS azifani ngendlela yokwakha: isitoreji esinamathiselwe kunethiwekhi sethula imisebenzi yenethiwekhi kanye nekhompyutha okungafanele ithathwe njenge-enclosure enamathiselwe ngqo ku-USB.

Kusukela ku-Prototype kuya ku-Production: Ukuhlolwa kwe-HDD Enclosure PCBA kanye ne-RFQ

I-prototype esebenzayo iwusizo, kodwa ukukhiqiza okuphindaphindiwe kudinga nereferensi ecacile: ukubuyekezwa kwe-PCB ne-BOM, izinombolo zezingxenye zesixhumi, ukucushwa kwebhuloho, idrayivu esekelwayo, umthombo wamandla, ikhebula lomsingathi kanye nenqubo yokuhlola.

Guqula izimpawu ezivamile zibe ukuhlolwa okuqondiwe kwefektri

Lezi izindlela zokwehluleka ezingaba khona kunokuthola ukuthi iphrojekthi ethile yamakhasimende iyasebenza yini:

• Kutholwe ibhuloho le-USB; i-HDD ayikho: Hlola ukuhlangana kwe-SATA, amandla edrayivu kanye nokucushwa kwesilawuli ngedrayivu yokubhekisela eyaziwayo.
• Nqamula ukuxhumana ngesikhathi sokujikeleza: Kala amandla kusixhumi se-HDD bese uhlola ukuthi ibhuloho liyasetha kabusha yini.
• Amaphutha okufunda/ukubhala ngezikhathi ezithile: Phinda ukuhlolwa kokudlulisa okuchaziwe nge-fixed drive, ikhebula, i-host kanye nezimo zamandla.
• I-dock bay eyodwa kuphela esebenzayo: Hlola ubunikazi be-bay, ukubuyekezwa kwe-socket/backplane kanye nendlela ngayinye yokushayela ecacisiwe.

I-Highleap ingaxoxa ngokuhlolwa okusebenzayo uma i-fixture, isofthiwe, i-reference drive kanye nemikhawulo yokwamukelwa inikezwa noma kuvunyelwana ngayo. Ukuhlola nge-drive eyodwa akuqinisekisi ukuhambisana kwe-HDD noma uhlelo lokusebenza.

Okufanele ukuthumele ukuze uthole ikhotheshini ewusizo ye-PCB/PCBA

• Amafayela e-PCB kanye nomhlangano: I-Gerber/ODB++, imidwebo yokwenziwa, i-BOM evunyiwe kanye nolwazi lokubekwa.
• Imininingwane yebhuloho: inombolo yengxenye yesilawuli, izidingo ze-USB interface kanye nanoma yimaphi amafayela e-firmware/okucushwa.
• Imininingwane yemishini: Imidwebo yesixhumi se-SATA/USB/DC, ama-enclosure datums kanye nezintambo zokuhlanganisa, uma zifakiwe.
• Amandla nokuhlolwa: i-HDD esekelwayo/ebhekisela kuyo, imininingwane yokuhlinzeka, ukuqala okulindelekile kanye nokuhlolwa kokudluliswa kwedatha.
• Ububanzi bamabhodi amaningi: amafayela ebhodi lamandla, inani le-PCBA ngayinye ngeyunithi ngayinye kanye nanoma yiziphi izingxenye ezithunyelwe.

Uma ezinye izakhi zomklamo zingakakhishwa, zichaze ngokucacile ukuze ikhotheshini ingakhiphi buthule imisebenzi edingekayo. Ukuhlanganiswa kwe-PCB ye-turnkey ye-Highleap kungabhekwa ngokuphathelene nokwakhiwa kwe-PCB okuvunyiwe, izingxenye kanye nezinhlangano ezinabantu abaningi. Ama-reference drive, izinto ezifakiwe, ukufakwa kwe-enclosure kanye nokuqinisekiswa okwengeziwe kufanele kuxoxwe ngakho ngokwehlukana uma kudingeka.
