Ishicilelwe ibhodi yesekethe (I-PCB) yinto ebalulekileyo kuyo yonke imboni ye-elektroniki. Ngemihla yokuqala, ukuveliswa kwePCB yayiyindlela ecothayo, eqhelekileyo. Njengoko itekhnoloji iye yaphucuka, inkqubo iye yakhawuleza, yoyilo ngakumbi kwaye yabanzima nangakumbi. Umthengi ngamnye ufuna utshintsho oluthile kwi-PCB ngaphakathi kwexesha elithile. Ngamanye amaxesha, imveliso ye-PCB yesiko ithatha ukuya kuthi ga kwiyure. Nangona kunjalo, ukuba i-PCB yesiko ivavanywa ngokusebenzayo ekupheleni kwenkqubo kwaye uvavanyo aluphumeleli, umenzi kunye nomthengi abanakho ukubanakho ukulahleka. Yilapho i-PCB prototyping ingena khona. Ukuboniswa kwe-PCB linyathelo elibalulekileyo kwimveliso ye-PCB, kodwa kutheni kubaluleke kangaka? Eli nqaku lixoxa ngokuthe ngqo ukuba zeziphi iiprototypes ekufuneka zibonelele kwaye kutheni zibalulekile.

Umzekelo wePCB Intshayelelo

I-PCB prototyping yinkqubo ephindaphindayo apho i-PCB abayili kunye neenjineli bazama uyilo lwe-PCB kunye neendlela zokuhlanganisa. Injongo yezi zinto ziphindaphindwayo kukuqinisekisa oyilo olululo lwePCB. Kwimveliso ye-PCB, izinto zebhodi yesekethe, izinto ze-substrate, izinto, ubeko lofakelo lwezinto, iitemplate, umaleko kunye nezinye izinto ziqwalaselwa ziphindaphindwe ziinjineli. Ngokudibanisa kwaye uthelekise uyilo kunye nemiba yokuvelisa yezi zinto, eyona ndlela yoyilo yePCB kunye neendlela zokuvelisa zinokuchongwa. Uninzi lwexesha, iiprototypes zePCB zenziwa kumaqonga abonakalayo. Nangona kunjalo, kwizicelo ezomeleleyo, iiprototypes ezibonakalayo zePCB zinokwenziwa ukuvavanya ukusebenza. I-PCB prototype inokuba yimodeli yedijithali, iprototype ebonakalayo, okanye iprototype esebenzayo ngokupheleleyo (efanayo). Ngenxa yokuba ukwenziwa kwezinto ngendlela ephuculweyo yayikukukwamkelwa kwangoko kwe-Manufacture and Design Design (i-DFMA), inkqubo yendibano ye-PCB inezibonelelo ezininzi ekuhambeni kwexesha.

Ukubaluleka prototype lemveliso kwimveliso PCB

Nangona abanye abavelisi bePCB betsiba ukubonisa ixesha lokuvelisa, ukwenza njalo kuhlala kuchasene. Nazi ezinye zezibonelelo zokuprototyping ezenza ukuba eli nyathelo lisebenze okanye libaluleke.

Iprototype ichaza ukuhamba koyilo lokwenziwa kunye nendibano. Oku kuthetha ukuba zonke izinto ezinxulumene nokwenziwa kunye nendibano ziqwalaselwa kuphela ngexesha loyilo lwe-PCB. Oku kunciphisa imiqobo kwimveliso.

Kwimveliso ye-PCB, izixhobo ezifanelekileyo zohlobo oluthile lwe-PCB zikhethwe ngexesha lokuqokelela. Kweli nqanaba, iinjineli zivavanya kwaye zizame izinto ezahlukeneyo ngaphambi kokukhetha efanelekileyo. Ke ngoko, iipropathi zezinto ezinje ngokuchasana nemichiza, ukumelana nerusi, ukuhlala ixesha elide, njl. Kuvavanywa kuphela kumanqanaba okuqala. Oku kugweba ukubakho kokusilela ngenxa yokungahambelani kwezinto kwinqanaba elizayo.

Ii-PCBS zihlala zenziwe ngobunzima. Uyilo olunye lwePCBS lusetyenziselwa imveliso yobunzima. Ukuba uyilo luyisiko, ukubakho kweempazamo kuyilo luphezulu. Ukuba kukho impazamo yoyilo, impazamo enye iyaphindaphindeka kumawakawaka e-PCBS kwimveliso yobuninzi. Oku kungakhokelela kwilahleko ebalulekileyo, kubandakanya izinto ezifakwayo, iindleko zemveliso, iindleko zokusetyenziswa kwezixhobo, iindleko zabasebenzi kunye nexesha. I-PCB prototyping inceda ekuchongeni nasekulungiseni iimpazamo zoyilo kwinqanaba lokuqala ngaphambi kwemveliso.

Rhoqo, ukuba impazamo yoyilo lwe-PCB ifunyenwe ngexesha lokuvelisa okanye lokuhlangana okanye lokusebenza, umyili kufuneka aqale ekuqaleni. Rhoqo, ubunjineli obubuyiswayo buyacelwa ukuba bujonge iimpazamo kwi-PCBS eyenziweyo. Ukuyila ngokutsha kunye nokuzala kwakhona kungachitha ixesha elininzi. Ngenxa yokuba ukuprosesa kusombulula iimpazamo kuphela kwinqanaba lokuyila, ukuphindaphinda kuyagcinwa.

Ziyilelwe kwaye zenziwe ukuba zibonakale kwaye zisebenze ngokufanayo xa kuthelekiswa neemfuno zokugqibela zemveliso. Ke ngoko, ukwenzeka kwemveliso kuyonyuka ngenxa yoyilo lweprototype.
