Ukutshintsha kweNethiwekhi ngumqolo wonxibelelwano lwanamhlanje, okuqinisekisa ukuhamba kwedatha engenamthungo phakathi kwezixhobo kushishino kunye neendawo zoshishino. Ukuveliswa kwala macandelo abalulekileyo kubandakanya inkqubo enzima kunye neyobuchule edibanisa iteknoloji yokusika, ubunjineli obuchanekileyo kunye nokulawulwa komgangatho ongqongqo ukuhambisa izixhobo ezithembekileyo, eziphezulu zokusebenza. Nantsi imbonakalo ngasemva kwenkqubo yokwenziwa kokutshintsha kwenethiwekhi.
1. Uyilo kunye nophuhliso
Uhambo lokuvelisa lokutshintsha kwenethiwekhi luqala ngokuyila kunye nesigaba sophuhliso. Iinjineli kunye nabaqulunqi basebenza kunye ukwenza iinkcukacha ezicacileyo kunye neeplani ezisekelwe kwiimfuno zemarike, ukuqhubela phambili kwezobuchwepheshe kunye neemfuno zabathengi. Eli nqanaba libandakanya:
Uyilo lwesekethe: Iinjineli ziyila iisekethe, kubandakanya ibhodi yesekethe eprintiweyo (PCB) esebenza njengomqolo wokutshintsha.
Ukukhetha icandelo: Khetha izinto ezikumgangatho ophezulu, ezinje ngeeprosesa, iitshiphu zememori, kunye nezixhobo zombane, ezihlangabezana nemigangatho yokusebenza kunye nokuqina okufunekayo kutshintsho lwenethiwekhi.
Iprototyping: Iiprototypes ziphuhliswa ukuvavanya ukusebenza, ukusebenza, kunye nokuthembeka koyilo. Iprototype iye yavavanywa ngokuqatha ukuchonga naziphi na iimpazamo kuyilo okanye iindawo zokuphucula.
2. Ukuveliswa kwePCB
Nje ukuba uyilo lugqityiwe, inkqubo yokuvelisa ingena kwinqanaba lokwenziwa kwePCB. Ii-PCB ngamacandelo aphambili agcina iisekethe ze-elektroniki kwaye zibonelela ngesakhiwo somzimba sokutshintsha kwenethiwekhi. Inkqubo yemveliso ibandakanya:
Ulwaleko: Ukusebenzisa iileya ezininzi zobhedu oluqhubayo kwi-non-conductive substrate kudala iindlela zombane ezidibanisa amacandelo ahlukeneyo.
I-Etching: Ukususa ubhedu obungeyomfuneko kwibhodi, ukushiya iphethini yesekethe echanekileyo efunekayo ekusebenzeni kokutshintsha.
Ukugrumba nokuPlating: Gqoka imingxuma kwiPCB ukuququzelela ukubekwa kwamacandelo. Le mingxunya ke ifakwe izinto zokuqhuba ukuqinisekisa uqhagamshelo olufanelekileyo lombane.
Isicelo seMaski ye-Solder: Faka i-mask ye-solder ekhuselayo kwi-PCB ukukhusela iisekethe ezimfutshane kunye nokukhusela ukujikeleza kumonakalo wokusingqongileyo.
ISilk Screen Printing: Iileyibhile kunye neziphawuli ziprintwe kwi-PCB ukukhokela ukudibanisa kunye nokusombulula ingxaki.
3. Indibano yeenxalenye
Nje ukuba iPCB ilungile, inyathelo elilandelayo kukudibanisa amacandelo ebhodini. Eli nqanaba libandakanya:
I-Surface Mount Technology (SMT): Ukusebenzisa oomatshini abazenzekelayo ukubeka amacandelo kumphezulu we-PCB ngokuchaneka okugqithisileyo. I-SMT yindlela ekhethwayo yokudibanisa iinqununu ezincinci, eziyinkimbinkimbi ezifana ne-resistors, i-capacitors, kunye neesekethe ezidibeneyo.
NgeTekhnoloji ye-Hole-Hole (THT): Kumacandelo amakhulu afuna inkxaso eyongezelelweyo yomatshini, amacandelo angaphakathi-umngxuma afakwe kwimingxuma esele igrunjwe ngaphambili kwaye ithengiswa kwi-PCB.
I-Reflow soldering: I-PCB edibeneyo idlula kwi-oven yokubuyisela apho i-solder paste inyibilika kwaye iqina, idala uqhagamshelwano olukhuselekileyo lombane phakathi kwezinto kunye ne-PCB.
4. Inkqubo yeFirmware
Nje ukuba udibaniso olubonakalayo lugqityiwe, i-firmware yokutshintsha kwenethiwekhi icwangcisiwe. I-Firmware yisoftware elawula ukusebenza kunye nokusebenza kwehardware. Eli nyathelo libandakanya:
Ukufakwa kweFirmware: I-Firmware ifakwe kwimemori yokutshintsha, ukuyivumela ukuba yenze imisebenzi esisiseko njengokutshintsha ipakethi, ukuhambisa umzila, kunye nolawulo lwenethiwekhi.
Uvavanyo kunye noCalibration: Ukutshintsha kuvavanywa ukuqinisekisa ukuba i-firmware ifakwe ngokuchanekileyo kwaye yonke imisebenzi isebenza njengoko kulindelwe. Eli nyathelo lingabandakanya uvavanyo loxinzelelo lokuqinisekisa ukusebenza kokutshintsha phantsi kwemithwalo yenethiwekhi eyahlukeneyo.
5. Ukulawulwa komgangatho kunye noVavanyo
Ukulawulwa komgangatho yinxalenye ebalulekileyo yenkqubo yokuvelisa, ukuqinisekisa ukuba utshintsho lwenethiwekhi nganye luhlangabezana nemigangatho ephezulu yokusebenza, ukuthembeka kunye nokhuseleko. Eli nqanaba libandakanya:
Uvavanyo olusebenzayo: Iswitshi nganye iyavavanywa ukuqinisekisa ukuba isebenza ngokufanelekileyo kwaye onke amazibuko kunye neempawu zisebenza njengoko kulindelekile.
Uvavanyo lokusingqongileyo: Utshintsho luvavanyelwa ubushushu, ukufuma, kunye nokungcangcazela ukuze kuqinisekiswe ukuba banokumelana neendawo ezahlukeneyo zokusebenza.
Uvavanyo lwe-EMI/EMC: Ukuphazamiseka kwe-Electromagnetic (EMI) kunye nokuhambelana kwe-electromagnetic compatibility (EMC) kwenziwa ukuqinisekisa ukuba iswitshi ayikhuphi imitha eyingozi kwaye inokusebenza nezinye izixhobo zombane ngaphandle kokuphazamiseka.
Uvavanyo lokutshisa: Ukutshintshwa kunikwe amandla kwaye kuqhutywe ixesha elide ukuchonga naziphi na iziphene ezinokuthi zenzeke ngexesha.
6. Indibano yokugqibela kunye nokupakishwa
Emva kokudlula zonke iimvavanyo zokulawula umgangatho, ukutshintshwa kwenethiwekhi kungena kwindibano yokugqibela kunye nesigaba sokupakisha. Oku kuquka:
