kodi pcb imatanthauza chiyani

M'dziko lonse la zamagetsi, chidule cha PCB chimagwiritsidwa ntchito kutanthauza bolodi losindikizidwa.Komabe, kwa iwo omwe sakudziwa zovuta zaukadaulo wovutawu, mawuwa amatha kusokoneza ndipo nthawi zambiri amadzutsa mafunso monga "Kodi PCB imatanthauza chiyani?"Ngati mupeza kuti mukufuna kudziwa za ma PCB ndipo mukufuna kumvetsetsa zoyambira zawo, muli pamalo oyenera.Blog iyi ikufuna kukupatsirani mafotokozedwe osavuta kumva okhudza ma PCB, kufunikira kwawo komanso momwe amagwiritsidwira ntchito masiku ano aukadaulo.

Sinthani PCB

Ma board osindikizira (PCBs) ndizofunikira kwambiri pamagetsi amakono.Amakhala ndi mapepala athyathyathya azinthu zopanda ma conductive monga magalasi a fiberglass omwe amakhala ngati maziko oyika zida zosiyanasiyana zamagetsi.Zigawozi zimalumikizidwa ndi netiweki yamayendedwe amkuwa, otchedwa traces, okhazikika pamwamba pa bolodi.

1. Kapangidwe ndi ntchito

Cholinga chachikulu cha PCB ndikupereka chithandizo chamakina ndi kulumikizana kwamagetsi pakati pa zida zamagetsi.Ili ndi udindo wowonetsetsa kulumikizana kolondola ndi kulumikizana pakati pazigawo zosiyanasiyana, kuphatikiza mabwalo ophatikizika (ICs), resistors, transistors, capacitors, ndi zina zambiri.Mayendedwe a trace pama board oyendera amathandizira kuti magetsi aziyenda mosavuta kuti zida zamagetsi zizigwira ntchito moyenera.

2. Ubwino wa PCB

Kuphatikiza ma PCB muzinthu zamagetsi kuli ndi zabwino zingapo.Choyamba, kapangidwe kawo kophatikizika kamathandizira kuti miniaturization, kukhathamiritsa malo mkati mwa zida zamagetsi.Kuphatikiza apo, kugwiritsa ntchito PCB kumachepetsanso mwayi wa zolakwika pamisonkhano, popeza zigawo zimayikidwa pa bolodi, zomwe zimathandizira kupanga.Ma PCB amaperekanso kulimba kwambiri poyerekeza ndi njira zina zamawaya.Zigawo zogulitsidwa zimatsimikizira kulumikizidwa kotetezeka ndikuchepetsa chiopsezo cha mawaya otayirira kapena kulumikizana kolakwika.

3. Mitundu ya ma PCB

Ma PCB amatha kusiyanasiyana movutikira, kapangidwe kake, ndi kuchuluka kwa magawo kuti akwaniritse zosowa za mapulogalamu ena.Mitundu ina yodziwika bwino ya ma PCB ndi ma PCB osanjikiza amodzi, osanjikiza awiri, ndi ma PCB amitundu yambiri.PCB yosanjikiza imodzi imakhala ndi gawo limodzi lamkuwa kumbali imodzi, pomwe PCB yokhala ndi zigawo ziwiri imakhala ndi mkuwa mbali zonse ziwiri.Ma PCB a Multilayer amakhala ndi zigawo zingapo zomwe zimayikidwa ndikulumikizidwa kudzera m'mabowo obowoledwa otchedwa vias, zomwe zimapangitsa kuti zigawo zambiri ziziphatikizidwa ndikuwongolera magwiridwe antchito.

4. Njira yopangira PCB

Kupanga kwa PCB kumaphatikizapo njira zingapo.Poyambirira, miyeso ya bolodi ndi masanjidwe a zigawozo zidapangidwa pogwiritsa ntchito pulogalamu yothandizidwa ndi makompyuta (CAD).Mapangidwewo akamaliza, amasamutsidwa ku bolodi ladera kudzera mufilimu yowonetsa zithunzi kapena chigoba choteteza.Madera a mkuwa oonekera amazimitsidwa pogwiritsa ntchito mankhwala osakaniza, n’kusiya malo amene akufuna.Potsirizira pake, zigawozo zimayikidwa pa bolodi ndi kugulitsidwa, kumaliza ndondomeko ya msonkhano.

Pomaliza

Mwachidule, matabwa osindikizira (PCBs) amagwira ntchito yofunika kwambiri pa zamagetsi, kupereka malumikizano ofunikira a magetsi ndi chithandizo cha makina pazida zosawerengeka.Kumvetsetsa zoyambira za PCB, kuphatikiza kapangidwe kake, ntchito, zopindulitsa, ndi njira zopangira, ndikofunikira kuti timvetsetse zovuta zamagetsi zomwe timakumana nazo tsiku lililonse.Pamene ukadaulo ukupitilirabe patsogolo, ma PCB mosakayikira akhalabe maziko azinthu zatsopano, kusinthika kuti akwaniritse zovuta ndi zosowa zatsopano.
