mawonekedwe athunthu a pcb ndi chiyani

PCB ndi chidule chomwe mungakumane nacho pokambirana zamagetsi kapena ma boardboard.Koma, kodi munayamba mwadzifunsapo kuti mawonekedwe athunthu a PCB ndi chiyani?Mu blog iyi, tikufuna kumvetsetsa bwino tanthauzo la mawu ofupikitsawa komanso tanthauzo lake pazamagetsi.

Kodi Printed Circuit Board ndi chiyani?

PCB imayimira "Printed Circuit Board".M'mawu osavuta, PCB ndi bolodi yozungulira yopangidwa ndi zinthu zopanda ma conductive ndi njira zowongolera zomwe zidakhazikikamo.Njirazi zimakhazikitsa kulumikizana pakati pazigawo zosiyanasiyana zamagetsi ndikulola gululo kuti lizigwira ntchito ngati gawo lathunthu.Ma PCB amagwiritsidwa ntchito pazida zosiyanasiyana zamagetsi, kuyambira zoseweretsa zosavuta ndi zida mpaka zida zapamwamba zachipatala ndi makompyuta.

Ubwino wa PCB

Ma PCB amapereka maubwino angapo kuposa njira zakale zolumikizira zida zamagetsi.Choyamba, iwo ndi ang'onoang'ono kwambiri, kuwapanga kukhala abwino kwa timagetsi tating'onoting'ono.Chifukwa cha kukula kwake, ma PCB nawonso ndi opepuka komanso osavuta kunyamula kuposa njira zachikhalidwe zamawaya.Chachiwiri, popeza njira zoyendetsera zimayikidwa mu bolodi, chiopsezo cha kuwonongeka kapena kutsekedwa kumachepetsedwa kwambiri.Izi zimapangitsa ma PCB odalirika kuposa njira zina.

Mitundu ya ma PCB

Pali mitundu yambiri ya PCB yomwe ilipo, iliyonse ili ndi cholinga chake.Nayi mitundu yodziwika kwambiri:

1. PCB ya mbali imodzi ndiye mtundu wofunikira kwambiri, njira zonse zoyendetsera zili mbali imodzi ya bolodi.Izi nthawi zambiri zimagwiritsidwa ntchito m'mabwalo osavuta, kuphatikiza zoseweretsa ndi zida zosavuta.

2. Ma PCB okhala ndi mbali ziwiri ali ndi njira zoyendetsera mbali zonse za bolodi, zomwe zimalola maulendo ovuta kwambiri.Komabe, akadali osavuta poyerekeza ndi zosankha zina.

3. Multilayer PCBs imakhala ndi zigawo zingapo za njira zoyendetsera, zomwe zimapangitsa kuti pakhale maulendo ovuta kwambiri.Izi nthawi zambiri zimagwiritsidwa ntchito pazida zamakono zamakono monga makompyuta ndi mafoni a m'manja.

4. Rigid-Flex PCBs ndi njira yatsopano yomwe imaphatikiza ubwino wa PCBs okhwima ndi osinthasintha.Ndizoyenera kugwiritsidwa ntchito pazida zomwe zimafunikira kukhala zamphamvu koma zosinthika, monga zida zamankhwala.

Pomaliza

Ponseponse, PCB ndi gawo lofunikira pazamagetsi zamagetsi, kupereka njira yodalirika komanso yabwino yolumikizira zida zamagetsi.Amapereka maubwino ambiri kuposa njira zachikhalidwe zamawaya, kuphatikiza kukula kocheperako, kulemera kopepuka, komanso kudalirika kwakukulu.Kudziwa mawonekedwe athunthu a PCB ndi mitundu yosiyanasiyana yomwe ilipo kungakuthandizeni kumvetsetsa bwino ntchito zomwe zigawozi zimagwira pa chipangizo chamagetsi.
