Ma PCB amatulutsa mafakitale ndi zida zambiri mdera lathu. Pomwe ukadaulo wathu ukusintha, momwemonso kufunikira kwa ma PCB osiyanasiyana. Mukasankha pakati pa ma PCB osanjikiza osanjikiza ndi angapo, zosankhazo zimawoneka zopanda malire. Musanagule PCB yatsopano, ndikofunikira kumvetsetsa zabwino ndi zoyipa za njira iliyonse. Izi ndi zina mwa zabwino zogula Mipikisano PCB pamapangidwe amodzi.

Choyamba, ndikofunikira kumvetsetsa kuti PCB yama multilayer ndi chiyani ndikupanga.

PCB yosanjikiza imodzi yokhala ndi zinthu zosanjikiza. Mudzapeza chithunzi cholumikizira cholumikizira chokwera mbali imodzi ya bolodi ndi zinthu zomwe zidakwezedwa mbali inayo. Ma PCB amtundu umodzi amagwiritsidwa ntchito pazida zosavuta chifukwa kulibe mawaya owolokera kuti dera lizigwira bwino ntchito. Ma PCB omwe ali ndi mbali ziwiri ndi ofanana, okhala ndi ntchito zambiri kuposa ma bolodi amodzi, koma osachepera ma PCB angapo. Ali ndi gawo limodzi lokhala ndi dielectric komanso chitsulo chosanjikiza mbali iliyonse.

Komano matabwa a Multilayer, ndi ovuta kuposa ma PCB amtundu umodzi kapena mbali ziwiri. Multilayer PCB ili ndi zigawo zitatu kapena zingapo zakuthupi. Zigawo zina, nthawi zambiri zojambulazo zamkuwa, zimakhazikika pamwamba pake.

Yambani ndi pachimake. Mzere uliwonse wowonjezedwa kuyambira pamenepo sunachiritsidwe kwathunthu. Mwanjira iyi, wopanga amatha kuwasintha mogwirizana ndi pachimake. Pambuyo pake, zojambulazo zimapitabe patsogolo ndipo zimatha kusinthana ndi zigawo zina ndikutsitsa. Njira zapanikizika ndi kutentha kwambiri ziyenera kugwiritsidwa ntchito kuphatikiza zigawozo ndikuziphatikiza mosamala.

PCB yosakwatira komanso yosanjikiza

Multilayer PCBS ili ndi maubwino ambiri. Ponseponse, ma board awa ndi ocheperako komanso opepuka, omwe amawapangitsa kukhala abwino pama foni am’manja kapena makompyuta, kapena zinthu zina zomwe zimafunikira ma CD osiyanasiyana. Nazi maubwino ena apadera:

Mipikisano wosanjikiza PCB limakupatsani ntchito zambiri.

Kuchuluka kwa msonkhano kumatanthauza kuti mutha kuwonjezera moyo wa bolodi lanu.

Kapangidwe kake ndi kophweka pomwe simufunikira zolumikizira ma PCBS angapo odziyimira pawokha.

Njira zoyeserera za LA pamalo opangira zikutanthauza kuti mudzalandira zinthu zabwino kwambiri.

Makhalidwe amagetsi a PCBS angapo amakhala othamanga kuposa matabwa amodzi.

L Kutengera kuchuluka kwa zigawo zomwe mungasankhe kuwonjezera, ma PCBS angapo amakhala abwino pazinthu zolimba komanso zosinthika.

Mosiyana ndi izi, pomwe ma PCBS osakwatira ali othandiza muntchito zina, amakhalanso ndi zovuta zina zomwe siziyenera kunyalanyazidwa. Nazi zovuta zina za olipira monolayiti:

Chifukwa mawaya sangathe kuwoloka, matumba amodzi amakhala oyenera pamagetsi osavuta ndipo samagwiritsa ntchito magwiridwe antchito ambiri.

L Ngakhale ma PCBS osakwatira ndi otchipa kupanga, satenga nthawi yayitali ngati ma PCBS angapo, kutanthauza kuti ndiopanda ndalama zambiri.

Ma PCBS osakwatira sangathe kukwaniritsa kuthamanga kwa anzawo osiyanasiyana.

L Mabotolo oyenda omwe amakhala ndi gawo limodzi amangokhala ozungulira kapangidwe kake chifukwa amakhala ndi kondakitala m’modzi yekha ndipo mzere uliwonse umafunikira njira yakeyake.

Ngakhale ma PCBS osanjikiza ndi chisankho chovomerezeka pamapangidwe ochepera, mawonekedwe a PCBS angapo amawapangitsa kukhala osankha bwino m’mafakitale ambiri omwe akufuna njira yokhazikika komanso yodalirika.

Ntchito multilayer PCB

Makampani ndi zinthu zambiri zitha kupindula ndi ma PCBS angapo, makamaka chifukwa chokhazikika, magwiridwe antchito, komanso kupepuka. Nazi zinthu zina zomwe nthawi zambiri zimagwiritsa ntchito matabwa awa:

L kompyuta

L Kuwunika mtima

L moto

LGPS ndi ma satellite

L Kuwongolera mafakitale
