Yini isixhumi?
Izixhumi ziyizingxenye zikagesi ezixhuma ukuhamba kukagesi namasignali kagesi.
Isixhumi ngokuvamile sibhekisela kumqhubi (umugqa) kanye nepheya efanele yezingxenye ezixhunywe ukuze kuzuzwe izingxenye zamanje noma zesignali ezivuliwe noma ezivaliwe ze-electromechanical, kudivayisi nezingxenye, izingxenye nezikhungo, amasistimu namasistimu angaphansi phakathi kokuxhunywa kukagesi nendima yokudlulisa isignali idivayisi.Eyaziwa nangokuthi izixhumi, amapulaki namasokhethi, azalwa ngobuchwepheshe bokukhiqiza izindiza zokulwa.Izindiza ezisempini kufanele zifakwe uphethiloli futhi zilungiswe phansi, futhi isikhathi esichithwa phansi siyisici esibalulekile ekunqobeni noma ekuhlulweni empini.Ngakho-ke, eMpini Yezwe II, iziphathimandla zezempi zase-US zanquma ukunciphisa isikhathi sokugcina phansi, zaqala ukuhlanganisa amathuluzi okulawula ahlukahlukene kanye nezingxenye, bese zixhunywa yizixhumi zibe uhlelo oluphelele.Lapho iyunithi engalungile ilungiswa, iyahlukaniswa futhi esikhundleni sayo kufakwe entsha, futhi indiza isuke ihamba emoyeni ngokushesha.Ngemuva kwempi, ngokukhuphuka kwekhompiyutha, ukuxhumana nezinye izimboni, isixhumi esivela kubuchwepheshe obuzimele sinamathuba amaningi okuthuthukiswa, imakethe iye yanda ngokushesha.
Kusukela endaweni yokubuka umsebenzi wokuxhuma, isixhumi singakwazi ukubona ukuxhumana phakathi kwesekethe ephrintiwe, i-base plate, imishini nokunye.Izindlela zokuqalisa eziyinhloko zihlukaniswe ngezigaba ezine: enye ingxenye ye-IC noma ingxenye ekuxhumaneni kwebhodi lesifunda eliphrintiwe, njenge-IC socket;Okubili yi-PCB ekuxhumekeni kwe-PCB, ngokuvamile njengesixhumi sesekethe esiphrintiwe;Okuthathu ukuhlobana phakathi kwepuleti eliphansi kanye nepuleti elingaphansi, elivamile njengesixhumi sekhabhinethi;Okwesine ukuxhumana phakathi kwemishini nezinto zokusebenza, okujwayelekile njengesixhumi esiyindilinga.Isabelo semakethe esikhulu kunazo zonke siwukuxhumanisa kwebhodi lesifunda eliphrintiwe kanye nemikhiqizo yokuxhumana kwemishini.
