Uma kukhulunywa ngezinto zikagesi, amabhodi esekethe aphrintiwe (ama-PCB) ayingxenye ebalulekile yokuklama kanye nenqubo yokukhiqiza.Kalula nje, i-PCB ibhodi elenziwe ngezinto ezingezona e-conductive ezinemizila ye-conductive noma imikhondo exhumanisa izingxenye ze-elekthronikhi ezihlukahlukene ezifana nama-resistors, ama-capacitor nama-transistors.
Idizayini ye-PCB ihlanganisa ukudala ukwakheka kokuxhunywa nezingxenye ebhodini lesekethe, okubalulekile ekuqinisekiseni ukusebenza okufanele nokuthembeka komkhiqizo.Njengoba ubuchwepheshe buqhubeka nokuthuthuka, isidingo sokuklama kwe-PCB ephumelelayo nesezingeni eliphezulu siyaqhubeka nokwanda.
Izinzuzo ze-PCB Design
Idizayini ye-PCB inikezela ngezinzuzo ezimbalwa ngaphezu kwezintambo zendabuko nezindlela zokwakha zamasekethe kagesi.Lokhu kubandakanya:
1. Ukonga isikhala: Ama-PCB aqeda isidingo sezintambo ezinkulu, ngakho-ke amadivaysi kagesi amancane, ahlangene kakhudlwana angadalwa.
2. Ukuqina: Ngenxa yokuthi ama-PCB enziwe ngezinto eziqinile futhi anokuxhumana okuqinile kwemishini, angakwazi ukumelana nezinga lokushisa eliphezulu, umswakama, nokudlidliza.
3. Ukungaguquguquki: Ama-PCB akhiqizwa futhi ahlanganiswe ngaphansi kwemihlahlandlela yokulawula ikhwalithi eqinile, ngaleyo ndlela anikeze ukusebenza okungaguquki.
4. Ukuvumelana nezimo: Idizayini ye-PCB ingenziwa ngendlela oyifisayo ukuze ihlangabezane nezidingo ezithile, okuhlanganisa usayizi, umumo kanye nenani lezendlalelo.
5. Angabizi kakhulu: Ama-PCB anciphisa izindleko zokukhiqizwa kwezinto zikagesi ngoba ayashesha futhi kulula ukuwenza kunezindlela zezintambo ezivamile.
Yini ehilelekile ekwakhiweni kwe-PCB?
Idizayini ye-PCB ibandakanya izigaba eziningi futhi inqubo ingahluka kuye ngobunkimbinkimbi bephrojekthi.Nokho, ezinye izinyathelo ezivamile ezihilelekile zihlanganisa:
1. Ukuthwebula okuhleliwe: Lokhu kuhilela ukudweba umdwebo wedizayini yesekethe ye-elekthronikhi, okuhlanganisa ukuxhumana namavelu engxenye ngayinye.
2. Isakhiwo se-PCB: Yilapho idizayini idluliselwa ebhodini eliphathekayo noma “kukhanvasi” futhi izingxenye kanye nemikhondo kubekwa kahle.
3. Ukwenziwa kwe-PCB: Ngemva kokuqedwa kokuhlelwa, ibhodi lesifunda lizodlula ezinqubweni zomshini eziningana ezihlanganisa ukucwiliswa, ukubhola, ukunamathisela nokuhlola.
4. Umhlangano: Yilapho izingxenye ze-elekthronikhi zixhunywe khona phezulu kwebhodi ngenqubo ebizwa ngokuthi i-Surface Mount Technology (SMT).
5. Ukuhlola Nokuqinisekisa: Uma isihlanganisiwe, ibhodi lingaphansi kokuhlolwa nokuqinisekiswa okuhlukahlukene ukuze kuqinisekiswe ukuthi konke ukuxhumeka kunembile nokuthi umklamo usebenza kahle.
Ekuphetheni
Idizayini ye-PCB iyisici esibalulekile sokukhiqiza idivayisi ye-elekthronikhi.Ngezinzuzo zabo eziningi, akumangazi ukuthi ama-PCB ayisinqumo esidumile phakathi konjiniyela bezinto zikagesi nabakhiqizi emhlabeni jikelele.Njengoba ubuchwepheshe buqhubeka nokuvela, ukwakheka kwe-PCB kuzohlala kuyikhono elibalulekile lochwepheshe kulo mkhakha.Ngokuqeqeshwa okufanele nezisetshenziswa, noma ubani angaba umklami we-PCB onekhono ongakha imikhiqizo ephezulu ye-elekthronikhi ngokuya ngezidingo nezimfuneko ezithile.
