Izinto zikagesi zanamuhla zinesidingo esikhulayo sama-PCB anezingqimba eziningi

Emhlabeni wezogesi, Amabhodi Esifunda Aphrintiwe (ama-PCB) adlala indima ebalulekile ekuxhumaniseni izingxenye ezihlukahlukene nokuqinisekisa ukusebenza kahle.Isidingo semishini ye-elekthronikhi emincane, esebenza kahle kakhulu, ethuthuke kakhulu siholele ekukhuleni okukhulu kobuchwepheshe be-PCB eminyakeni edlule.Enye intuthuko enjalo i-PCB enezingqimba eziningi, eqhubeka idume kakhulu kuma-electronics wanamuhla.Le bhulogi ihlose ukuveza ukubaluleka kanye nezinzuzo zama-PCB anezingqimba eziningi endaweni yobuchwepheshe ehlala ishintsha.

Funda mayelana nama-PCB amaningi.
Ukuze uqonde ukubaluleka kwe-PCB enezingqimba eziningi, umuntu kufanele aqonde ukwakheka kwayo okuyisisekelo.Ngokungafani nama-PCB endabuko anengqimba eyodwa noma ekabili, ama-PCB anezingqimba eziningi akhiwa izendlalelo eziningi zezinto eziqhutshwayo ezihlukaniswa ngezinto ezisetshenziswayo ze-dielectric.Lezi zingqimba zixhunywe nge-vias, okuvumela amasignali kagesi ukuthi ageleze ngaphandle komthungo ebhodini lesekethe.Inani lezendlalelo lingasukela kwezine kuye kwezingamashumi, kuye ngobunkimbinkimbi besekhethi kanye nezidingo zedivayisi.

Izinzuzo zeI-PCB ye-multilayer:

1. Idizayini ehlangene: Ama-PCB amaningi anika amandla abaklami ukuthi bakhe izinto zikagesi ezihlangene nezincane ngaphandle kokuphazamisa ukusebenza kwazo.Ikhono lokupakisha izendlalelo eziningi ziqonde mpo livumela ukusetshenziswa kahle kwendawo futhi lilungele imikhiqizo efana nama-smartphone, izinto ezigqokwayo namadivayisi ezokwelapha.

2. Ukuthuthukiswa komsebenzi: Izendlalelo eziningi ku-PCB enezingqimba eziningi zinendawo eyengeziwe yokuhlanganisa izingxenye eziningi namasekhethi ayinkimbinkimbi.Lokhu kuvumela ukufakwa kwezici ezithuthukile njengamandla angenantambo, amasistimu okuphatha amandla, ukudluliswa kwedatha okunesivinini esikhulu, nokuningi.Ukusebenza okuthuthukisiwe okunikezwa ama-PCB amaningi kwenza abakhiqizi bahlangabezane nezidingo ezikhulayo zemakethe.

3. Ubuqotho besignali kanye ne-EMI encishisiwe: Njengoba isivinini sedatha siqhubeka nokwanda futhi kudingeka ukudluliswa kwesignali yekhwalithi ephezulu, ama-PCB anezingqimba eziningi ahamba phambili ekuqinisekiseni ubuqotho besignali nokunciphisa ukuphazamiseka kwe-electromagnetic (EMI).Ngokuhlukanisa amandla nezindiza eziphansi ezindizeni zesignali, lawa mabhodi anciphisa i-crosstalk futhi agcine ubuqotho bezimpawu ezithambile.Lokhu kwandisa izilinganiso zokudluliswa kwedatha futhi kunciphisa amathuba amaphutha noma ukuphazamiseka.

4. Ukuthembeka okuthuthukisiwe: Uma kuqhathaniswa ne-PCB enesendlalelo esisodwa noma enezingqimba ezimbili, i-PCB enezingqimba eziningi inokwethembeka okungcono.Ukusatshalaliswa kanye nomzila wezingxenye kuzo zonke izendlalelo eziningi kunciphisa ubungozi bephoyinti elilodwa lokuhluleka.Ukwengeza, ukucwenga ngembobo kanye ne-vias kuthuthukisa ukwakheka okuphelele futhi kwenza ibhodi likwazi ukumelana nokucindezeleka okushisayo nokudlidliza, okulenze lifanelekele ukusetshenziswa emikhakheni yezimoto, i-aerospace kanye nezimboni.

5. Ukuguquguquka kwedizayini: Ukuhlukahluka kwama-PCB anezingqimba eziningi kwenza abaklami bakwazi ukusebenzisa izakhiwo eziyinkimbinkimbi, ukuhlanganisa amasekhethi e-analog nedijithali.Lokhu kuvumelana nezimo kunikeza onjiniyela inkululeko eyengeziwe yokusungula nokwenza lula inqubo yokuklama.Ukwengeza, ukuguqulwa komklamo wesifunda kanye nezinguquko kungenziwa ngaphandle kokuthinta ukuhlelwa kwebhodi lonke, ukunciphisa isikhathi sokuthuthukiswa kanye nezindleko.

Hlangana nezidingo zesimanje zikagesi:

Isidingo esikhulayo semishini kagesi emincane, ehlakaniphile sidinga ukusetshenziswa kwama-PCB anezingqimba eziningi.Ikhono labo lokwamukela ukusebenza okwengeziwe, ukuhlinzeka ngobuqotho besignali okuthuthukisiwe, ukuthuthukisa ukwethembeka kanye nokunikeza ukuguquguquka kwedizayini kubenza babe ukukhetha okuhlakaniphile kubakhiqizi abafuna ukuhlala ngaphambi komkhakha wezobuchwepheshe othuthukayo ngokushesha.

Ama-PCB ama-Multilayer aguqule imboni yezogesi ngokunikeza izinzuzo eziningi ngaphezu kwamabhodi esekethe endabuko.Njengoba isidingo semishini ye-elekthronikhi edidiyelwe kakhulu, ehlangene futhi ethuthukisiwe iqhubeka nokukhula, ukubaluleka kwama-PCB anezingqimba eziningi kuya ngokuya kubonakala.Ngokwamukela lobu buchwepheshe, abakhiqizi bangahlangabezana nesidingo sabathengi semikhiqizo emisha kuyilapho beqinisekisa ukwethembeka, ukusebenza kanye nokwaneliseka kwamakhasimende kukonke.
