Wake wacabanga ukuthi ibhodi lakho lesifunda se-elekthronikhi lihlangane kanjani?Futhi yiziphi izindlela ezisetshenziswa kakhulu ekuhlanganiseni kwe-PCB?Lapha, uzofunda kabanzi mayelana nendlela yokuhlanganisa ekuhlanganiseni kwe-PCB.
Incazelo ye-SMT
I-SMT(I-Surface Mount Technology) iwuhlobo olulodwa lwendlela yokuhlanganisa ibhodi le-PCB, indlela yokukhiqiza amasekhethi kagesi, lapho ezinye izingxenye zifakwa phezu kwawo.Ibizwa nge-SMT (Surface Mount Technology).Ithathele indawo ubuchwepheshe be- through-hole lapho izakhi zazixhunywana ngezintambo ezidlula emigodini ebhontshiwe.
Cishe zonke izingxenye ze-elekthronikhi ezikhiqizwa ngobuningi zanamuhla zenziwa kusetshenziswa ubuchwepheshe bokukhweza phezulu, i-SMT.Imishini yokukhweza engaphezulu ehlotshaniswayo, ama-SMD ahlinzeka ngezinzuzo eziningi ngaphezu kwabanduleli bawo abaholayo ngokuya ngokwenziwa kanye nokusebenza ngokuvamile.
Umehluko phakathi kwe-SMT ne-THT
Ngokuvamile kunezinhlobo ezimbili zendlela yokuhlanganisa i-PCB, i-SMT ne-THT
Ingxenye ye-SMT ivamise ukuba yincane ngosayizi kunobuchwepheshe be- through- hole ngoba ayinawo umkhondo wokuthatha yonke indawo ekhululekile.Kodwa-ke, inamaphini amancane ezitayela ezahlukene, i-matrix yamabhola e-solder, nokuxhumana okuyisicaba lapho umzimba wengxenye uphela khona ukuze uyibambe ngokuqinile.
Kungani i-SMT isetshenziswa kabanzi?
Amabhodi esekethe enziwe nge-elekthronikhi akhiqizwe ngobuningi adinga ukwakhiwa ngendlela enemishini eminingi ukuze kuqinisekiswe izindleko eziphansi zokukhiqiza.Izingxenye ze-elekthronikhi ezihamba phambili aziziboleki kule ndlela.Nakuba umshini othile wawungenzeka, umkhondo wengxenye kwakudingeka usungulwe kusengaphambili.Futhi lapho izintambo zifakwa emabhodini ngokuzenzakalelayo izinkinga zazivame ukuhlangatshezwana nazo njengoba izintambo zazivame ukungangeni kahle amazinga okukhiqiza anciphisa kakhulu.
I-SMT isetshenziswa cishe kuphela ekwenzeni amabhodi esekethe kagesi kulezi zinsuku.Zincane, ngokuvamile zinikeza izinga elingcono lokusebenza futhi zingasetshenziswa nomshini wokukhetha nendawo ozenzakalelayo okuthi ezimweni eziningi konke kususe isidingo sokungenelela okwenziwa ngesandla enqubweni yokuhlanganisa.
I-PHILIFAST inikezelwe emhlanganweni we-SMT kanye ne-THT iminyaka engaphezu kweyishumi, banethimba lonjiniyela abaningi abanolwazi futhi basebenza ngokuzinikezela.Konke ukudideka kwakho kuzoxazululwa kahle kakhulu ku-PHILIFAST.
