Ukushintsha kwenethiwekhi kuwumgogodla wamanethiwekhi esimanjemanje okuxhumana, aqinisekisa ukugeleza kwedatha okungenazihibe phakathi kwamadivayisi ezindaweni zebhizinisi nezimboni. Ukukhiqizwa kwalezi zingxenye ezibalulekile kuhilela inqubo eyinkimbinkimbi futhi ecophelelayo ehlanganisa ubuchwepheshe obusezingeni eliphezulu, ubunjiniyela obunembayo kanye nokulawulwa kwekhwalithi okuqinile ukuze kuhanjiswe imishini ethembekile, esebenza kahle kakhulu. Nakhu ukubheka ngemuva kwenqubo yokukhiqiza yokushintsha kwenethiwekhi.
1. Ukuklama nokuthuthukiswa
Uhambo lokukhiqiza lokushintsha kwenethiwekhi luqala ngesigaba sokuklama nesokuthuthukiswa. Onjiniyela nabaklami basebenza ndawonye ukuze bakhe ukucaciswa okuningiliziwe namapulani ngokusekelwe ezidingweni zemakethe, intuthuko yezobuchwepheshe kanye nezidingo zamakhasimende. Lesi sigaba sihlanganisa:
Idizayini yesiyingi: Onjiniyela baklama amasekhethi, okuhlanganisa nebhodi lesekethe eliphrintiwe (PCB) elisebenza njengomgogodla weswishi.
Ukukhetha izingxenye: Khetha izingxenye zekhwalithi ephezulu, njengamaphrosesa, ama-memory chips, nezinto ezisetshenziswayo zikagesi, ezihlangabezana nezindinganiso zokusebenza nokuqina ezidingekayo kumaswishi enethiwekhi.
I-Prototyping: Ama-Prototypes athuthukiswa ukuhlola ukusebenza, ukusebenza, nokuthembeka komklamo. I-prototype ihlolwe kanzima ukuze ihlonze noma yimaphi amaphutha edizayini noma izindawo okufanele zithuthukiswe.
2. Ukukhiqizwa kwe-PCB
Uma umklamo usuqediwe, inqubo yokukhiqiza ingena esigabeni sokwenziwa kwe-PCB. Ama-PCB ayizingxenye ezibalulekile ezigcina amasekhethi e-elekthronikhi futhi ahlinzeke ngesakhiwo esibonakalayo sokushintshwa kwenethiwekhi. Inqubo yokukhiqiza ihlanganisa:
Ukwendlalela: Ukusebenzisa izendlalelo eziningi zethusi eliqhubayo ku-substrate engaphenduki kudala izindlela zikagesi ezixhuma izingxenye ezihlukahlukene.
I-Etching: Ukukhipha ithusi elingadingekile ebhodini, kushiya iphethini yesekethe enembile edingekayo ekusebenzeni kokushintsha.
Ukubhola nokuPlating: Geza izimbobo ku-PCB ukuze kube lula ukubekwa kwezingxenye. Lezi zimbobo zibe sezigqitshwa ngezinto ezihambisa ugesi ukuze kuqinisekiswe ukuxhumana kahle kukagesi.
Isicelo Semaski ye-Solder: Faka imaski evikelayo ku-PCB ukuvikela amasekhethi amafushane futhi uvikele ukujikeleza ekulimaleni kwemvelo.
Ukuphrinta kwesikrini sikasilika: Amalebula nezihlonzi ziphrintwa ku-PCB ukuze ziqondise ukuhlanganisa nokuxazulula izinkinga.
3. Ukuhlanganiswa kwezingxenye
Uma i-PCB isilungile, isinyathelo esilandelayo ukuhlanganisa izingxenye ebhodini. Lesi sigaba sibandakanya:
I-Surface Mount Technology (SMT): Ukusebenzisa imishini ezenzakalelayo ukubeka izingxenye endaweni ye-PCB ngokunemba okukhulu. I-SMT iyindlela ekhethwayo yokuxhuma izingxenye ezincane, eziyinkimbinkimbi njengama-resistors, ama-capacitor, nama-circuits ahlanganisiwe.
I-Thry-Hole Technology (THT): Ezingxenyeni ezinkulu ezidinga ukwesekwa okwengeziwe kwemishini, izingxenye zembobo zifakwa emigodini ebhojwe ngaphambili futhi zidayiselwe ku-PCB.
I-Reflow soldering: I-PCB ehlanganisiwe idlula kuhhavini wokugeleza kabusha lapho inhlama ye-solder incibilika futhi iqine, idale uxhumano oluvikelekile lukagesi phakathi kwezingxenye ne-PCB.
4. Uhlelo lwe-Firmware
Uma ukuhlanganisa okungokoqobo sekuqediwe, i-firmware yeswishi yenethiwekhi iyahlelwa. I-Firmware isofthiwe elawula ukusebenza nokusebenza kwehadiwe. Lesi sinyathelo sihlanganisa:
Ukufakwa kwe-Firmware: I-Firmware ifakwe kumemori yeswishi, ukuyivumela ukuthi yenze imisebenzi eyisisekelo njengokushintshwa kwephakethe, umzila, nokuphathwa kwenethiwekhi.
Ukuhlola Nokulinganisa: Iswishi ihlolwe ukuze kuqinisekiswe ukuthi i-firmware ifakwe ngendlela efanele futhi yonke imisebenzi isebenza ngendlela elindelekile. Lesi sinyathelo singase sifake ukuhlolwa kwengcindezi ukuze kuqinisekiswe ukusebenza kweswishi ngaphansi kwemithwalo ehlukahlukene yenethiwekhi.
5. Ukulawula Ikhwalithi Nokuhlola
Ukulawulwa kwekhwalithi kuyingxenye ebalulekile yenqubo yokukhiqiza, ukuqinisekisa ukuthi ukushintsha kwenethiwekhi ngayinye kuhlangabezana namazinga aphezulu kakhulu okusebenza, ukwethembeka nokuphepha. Lesi sigaba sibandakanya:
Ukuhlola Okusebenzayo: Iswishi ngayinye ihlolwa ukuze kuqinisekiswe ukuthi isebenza kahle nokuthi zonke izimbobo nezici zisebenza njengoba kulindelekile.
Ukuhlolwa kwemvelo: Amaswishi ahlolelwa izinga lokushisa, umswakama, nokudlidliza ukuze kuqinisekiswe ukuthi angakwazi ukumelana nezinhlobonhlobo zezindawo zokusebenza.
Ukuhlolwa kwe-EMI/EMC: Ukuhlolwa kwe-electromagnetic interference (EMI) kanye ne-electromagnetic comppatibility (EMC) kwenziwa ukuze kuqinisekiswe ukuthi iswishi ayikhiphi imisebe eyingozi futhi ingasebenza namanye amadivaysi kagesi ngaphandle kokuphazamiseka.
Ukuhlolwa kokushiswa: Iswishi ivuliwe futhi isebenza isikhathi eside ukuze kuhlonzwe noma yikuphi ukukhubazeka okungenzeka noma ukwehluleka okungenzeka ngokuhamba kwesikhathi.
6. Ukuhlanganiswa kokugcina nokupakishwa
Ngemva kokudlula zonke izivivinyo zokulawula ikhwalithi, ukushintshwa kwenethiwekhi kungena esigabeni sokugcina sokuhlanganisa nokupakisha. Lokhu kuhlanganisa:
I-Enclosure Assembly: I-PCB kanye nezingxenye kufakwe ngaphakathi kwendawo ebiyelwe isikhathi eside eklanyelwe ukuvikela iswishi ekulimaleni ngokomzimba nasezicini zemvelo.
Ukulebula: Iswishi ngayinye ifakwe ilebula yolwazi lomkhiqizo, inombolo yomkhiqizo, kanye nokumaka ukuthobela imithetho.
Ukupakisha: Iswishi ipakishwe ngokucophelela ukuze inikeze ukuvikeleka ngesikhathi sokuthunyelwa nokugcinwa. Iphakheji ingase futhi ifake imanuwali yomsebenzisi, ukunikezwa kwamandla, nezinye izisetshenziswa.
7. Ukuthumela kanye Nokusabalalisa
Uma isihlanganisiwe, isishintshi senethiwekhi sesilungele ukuthunyelwa nokusabalalisa. Zithunyelwa ezindaweni zokugcina izimpahla, abasabalalisi noma ngokuqondile kumakhasimende emhlabeni jikelele. Ithimba lezokuthutha liqinisekisa ukuthi amaswishi alethwa ngokuphepha, ngesikhathi, futhi alungele ukuthunyelwa ezindaweni ezihlukahlukene zenethiwekhi.
Ekuphetheni
Ukukhiqizwa kokushintshwa kwenethiwekhi kuyinqubo eyinkimbinkimbi ehlanganisa ubuchwepheshe obuthuthukisiwe, ubuciko obunamakhono kanye nokuqinisekiswa kwekhwalithi okuqinile. Zonke izinyathelo ezisuka ekuklanyweni nasekukhiqizeni i-PCB ukuya ekuhlanganiseni, ekuhlolweni nasekupakishweni kubalulekile ekuletheni imikhiqizo ehlangabezana nezidingo eziphezulu zengqalasizinda yenethiwekhi yanamuhla. Njengomgogodla wamanethiwekhi ezokuxhumana esimanje, lezi zinguquko zidlala indima ebalulekile ekuqinisekiseni ukugeleza kwedatha okuthembekile nokusebenza kahle kuzo zonke izimboni nezinhlelo zokusebenza.
