Izingxenye zebhodi lesifunda eliphrintiwe(PCB)

1. Ungqimba

Ibhodi Lesifunda Eliphrintiwe(PCB) ungqimba ihlukaniswe ungqimba zethusi futhi non-ithusi ungqimba, ngokuvamile wathi izingqimba ezimbalwa ibhodi ukukhombisa inombolo ungqimba ungqimba zethusi.Ngokuvamile, ama-welding pads kanye nemigqa ibekwe phezu kwe-copper coating ukuze kuqedelwe uxhumano lukagesi.Beka uhlamvu lwencazelo yesici noma uhlamvu lwamazwana kunamathela okungelona ithusi;Ezinye izendlalelo (njengezendlalelo ezisetshenziswayo) zisetshenziselwa ukubeka ulwazi olubonisayo mayelana nokwakhiwa kwebhodi nendlela yokuhlanganisa, njengomugqa wobukhulu bebhodi, ukumaka ubukhulu, idatha yedatha, ngolwazi lwembobo, imiyalelo yokuhlanganisa, njll.

2.Nge

Ngembobo ingenye yezingxenye ezibalulekile ze-PCB ye-multilayer.Izindleko zokumba imbobo ngokuvamile zingu-30% kuya ku-40% wezindleko zebhodi lesifunda eliphrintiwe(PCB).Ngamafuphi, yonke imbobo ku-PCB ingabizwa ngokuthi i- through-hole.Ngokombono wokusebenza, imbobo yokudlula ingahlukaniswa ngezigaba ezimbili: eyodwa isetshenziswa njengokuxhumana kukagesi phakathi kwesendlalelo ngasinye;Eyesibili isetshenziselwa ukulungisa noma ukuthola amadivaysi.Ngokwenqubo yezobuchwepheshe, izimbobo ngokuvamile zihlukaniswa izigaba ezintathu, okungukuthi, impumputhe nge.Ingcwatshwe nge.

3. Iphedi

Iphedi isetshenziselwa izakhi zokushisela, ukuqaphela ukuxhumana kukagesi, ukulungisa izikhonkwane zezingxenye noma izintambo zokudweba, imigqa yokuhlola, njll. Ngokusho kohlobo lwephakheji yezingxenye, iphedi ingahlukaniswa izigaba ezimbili: i-pad yokufaka inaliti kanye nendawo. iphedi ye-patch.Iphedi yokufaka inaliti kufanele ibhojwe, kuyilapho iphedi engaphezulu ingadingeki ukuthi ibhojwe.Ipuleti lokushisela lezingxenye zohlobo lokufakwa kwezinaliti lisethwe ku-multi-layer, futhi ipuleti lokushisela lezingxenye zohlobo lwe-SMT lisethwe kungqimba olufanayo nezingxenye.

4.Ithrekhi

I-Copper film wire iwucingo olusebenza ku-PCB ngemva kokuthi ipuleti le-copper clad licutshunguliwe.Ibizwa ngokuthi i-wire ngamafuphi.Ngokuvamile isetshenziselwa ukubona ukuxhumana phakathi kwamaphedi futhi iyingxenye ebalulekile yebhodi lesifunda eliphrintiwe(PCB).Impahla eyinhloko yocingo ububanzi bayo, okuncike enanini lokuthwala okwamanje kanye nobukhulu be-foil yethusi.

5. Iphakheji Yengxenye

Iphakheji lengxenye lisho ukushisela ingxenye yangempela ebhodini lesekethe ephrintiwe(PCB) ukuholela izikhonkwane ngaphandle.Khona-ke iphakheji engaguquki iba yinto ephelele.Izinhlobo ze-encapsulation ezijwayelekile ziyi-plug-in encapsulation kanye ne-surface mounted encapsulation.
