Amabhodi wesifundayizici ezibalulekile zeimikhiqizo kagesi.Ake sibheke izingxenye zamabhodi wesifunda:
1. Iphedi:
Amaphedi yizimbobo zensimbi ezisetshenziselwa ukuthengisa izikhonkwane zengxenye.
2 isendlalelo:
Ngokuya ngokwakhiwa kwebhodi lesifunda, kuzoba nezinhlangothi ezimbili, ungqimba olu-4, ungqimba olu-6, ungqimba lwe-8, njll. Inani lezendlalelo ngokuvamile liphindwe kabili.Ngaphezu kwesendlalelo sesignali, kunezinye izendlalelo ezisetshenziselwa ukuchaza ukucubungula.
3. Nge:
Incazelo ye-vias ukuthi uma isifunda singakwazi ukusebenzisa yonke iminonjana yesignali ezingeni elilodwa, imigqa yesignali kufanele ixhunywe kuzo zonke izendlalelo ngokusebenzisa.I-Vias ngokuvamile ihlukaniswe yaba izinhlobo ezimbili, enye insimbi nge, enye ingeyona eyensimbi.I-Metal via isetshenziselwa ukuxhuma izikhonkwane zengxenye phakathi kwezendlalelo.Ifomu nobubanzi be-via kuncike ezicini zesignali kanye nezidingo zesikhungo sokucubungula.
4. Izingxenye:
Izingxenye zithengiswa ku-PCB.Inhlanganisela yesakhiwo phakathi kwezingxenye ezihlukene ingafinyelela imisebenzi eyahlukene, okuphinde kube indima ye-PCB .
5. Isakhiwo:
Isakhiwo sibhekisela kulayini wesignali oxhuma izikhonkwane zocingo.Ubude nobubanzi besakhiwo buncike kumvelo yesiginali, njengosayizi wamanje, isivinini, njll.
6. Ukuphrinta Isikrini:
Isikrini sokuphrinta singaphinda sibizwe ngokuthi isendlalelo sokuphrinta isikrini, esisetshenziselwa ukumaka ulwazi oluhlukahlukene oluhlobene nezingxenye.Ukuphrinta kwesikrini kuvamise ukuba mhlophe, futhi ungakhetha nombala ngokwezidingo zakho.
7. Imaski ye-solder:
Umsebenzi oyinhloko we-mask solder ukuvikela ubuso be-PCB, ukwakha ungqimba oluvikelayo olunogqinsi oluthile, nokuvimbela ukuthintana phakathi kwethusi nomoya.Imaski ye-solder ngokuvamile iluhlaza, kodwa kukhona futhi okubomvu, okuphuzi, okuluhlaza okwesibhakabhaka, okumhlophe, nokumnyama.
8. Imbobo yokubeka:
Imbobo yokubeka iyimbobo ebekwe kalula ukuze ifakwe noma ilungiswe.
9. Ukugcwalisa:
Ukugcwalisa kuyithusi elisetshenziswe kunethiwekhi yomhlabathi, enganciphisa ngempumelelo impedance.
10. Imingcele kagesi:
Umngcele kagesi usetshenziselwa ukunquma ubukhulu bebhodi lesifunda, futhi zonke izingxenye ebhodini lesifunda akufanele zidlule lo mngcele.
Izingxenye ezingenhla eziyishumi ziyisisekelo sokubunjwa kwebhodi lesifunda, futhi ukugcwaliseka kwemisebenzi eminingi kusadingeka kuhlelwe ku-chip ukuze kuzuzwe.
