Ngikholelwa ukuthi abantu abaningi abawazi amabhodi wesifunda we-PCB, futhi bangase bazwakale kaningi ekuphileni kwansuku zonke, kodwa bangase bangazi okuningi nge-PCBA, futhi bangase badideke ne-PCB.Ngakho yini i-PCB?I-PCBA yavela kanjani?Uyini umehluko phakathi kwe-PCB ne-PCBA?Ake sibhekisise.
Mayelana PCB
I-PCB isifinyezo se-Printed Circuit Board, ehunyushwa olimini lwesiShayina ibizwa ngokuthi ibhodi lesifunda eliphrintiwe, ngoba lenziwa ngokuphrinta nge-elekthronikhi, libizwa ngokuthi “ibhodi lesifunda eliphrintiwe”.I-PCB iyingxenye ye-elekthronikhi ebalulekile embonini ye-elekthronikhi, isekela izingxenye ze-elekthronikhi, kanye nesithwali sokuxhunywa kukagesi kwezingxenye ze-elekthronikhi.I-PCB isetshenziswe kabanzi kakhulu ekwenzeni imikhiqizo ye-elekthronikhi.Izici ezihlukile ze-PCB zifinyezwa kanje:
1. Ubuningi bezintambo eziphezulu, usayizi omncane kanye nesisindo esincane, esivumelana ne-miniaturization yemishini kagesi.
2. Ngenxa yokuphindaphinda nokungaguquguquki kwehluzo, amaphutha ekuxhumeni nasekuhlanganiseni ayancishiswa, futhi ukugcinwa kwemishini, ukulungisa iphutha kanye nesikhathi sokuhlola kuyagcinwa.
3. Kuyasiza ekusetshenzisweni kwemishini nasekukhiqizeni okuzenzakalelayo, okuthuthukisa ukukhiqizwa kwabasebenzi futhi kunciphisa izindleko zemishini kagesi.
4. Umklamo ungalinganiswa ukuze kube lula ukushintshashintsha.
MayelanaPCBA
I-PCBA isifinyezo se-Printed Circuit Board +Assembly, okusho ukuthi i-PCBA idlula kuyo yonke inqubo yokukhiqiza ye-PCB engenalutho yebhodi le-SMT bese kuba i-plug-in ye-DIP.
Qaphela: Kokubili i-SMT ne-DIP kuyizindlela zokuhlanganisa izingxenye ku-PCB.Umehluko omkhulu ukuthi i-SMT ayidingi ukubhoboza izimbobo ku-PCB.Ku-DIP, izikhonkwane ze-PIN zezingxenye zidinga ukufakwa emigodini ebhoboziwe.
Ubuchwepheshe bokukhweza phezulu be-SMT (Surface Mounted Technology) busebenzisa izikhwezi ukukhweza izingxenye ezithile ezincane ku-PCB.Inqubo yokukhiqiza ithi: Ukuma kwebhodi le-PCB, ukuphrinta kokunamathisela kwe-solder, ukukhwezwa kwe-mounter, kanye ne-reflow Furnace kanye nokuhlola okuphelile.
I-DIP isho “plug-in”, okungukuthi, ukufaka izingxenye ebhodini le-PCB.Lokhu ukuhlanganiswa kwezingxenye ngendlela yama-plug-in lapho ezinye izingxenye zinkulu ngosayizi futhi zingabufanele ubuchwepheshe bokubeka.Inqubo yokukhiqiza eyinhloko yile: ukunamathela okunamathelayo, i-plug-in, ukuhlola, i-wave soldering, ukuphrinta nokuhlola okuphelile.
*Umehluko phakathi kwe-PCB ne-PCBA*
Kusukela esingenisweni esingenhla, singakwazi ukwazi ukuthi i-PCBA ngokuvamile ibhekisela kwinqubo yokucubungula, engaqondwa futhi njengebhodi lesifunda eliqediwe, okusho ukuthi i-PCBA ingabalwa kuphela ngemva kokuba izinqubo ezisebhodini le-PCB seziqediwe.I-PCB isho ibhodi lesifunda eliphrintiwe elingenalutho elingenazo izingxenye kulo.
Ngokuvamile: I-PCBA iyibhodi eliqediwe;I-PCB iyibhodi elingenalutho.
