Abstract: In PCB mai sauri ƙira, ta hanyar ƙirar rami muhimmin abu ne, an haɗa shi da rami, kushin da ke kusa da ramin da yankin keɓewar Layer WOW, yawanci ana raba shi zuwa makahon rami, ramin da aka binne kuma ta rami iri uku. Ta hanyar nazarin ƙarfin parasitic capacitance da parasitic inductance a cikin ƙirar PCB, an taƙaita wasu maki don kulawa a cikin ƙirar PCB mai sauri.

Mahimman kalmomi: ta rami; Parasitic capacitance; Ƙaddamarwa na parasitic; Fasaha rami mara shiga

Babban ƙirar PCB mai sauri a cikin sadarwa, kwamfuta, aikace-aikacen sarrafa hoto, duk ƙirar ƙirar kayan lantarki mai ƙima mai ƙima a cikin bin ƙarancin amfani da wutar lantarki, ƙarancin wutar lantarki, babban abin dogaro, ƙaramin ƙarfi, ƙaramin aiki da sauransu, don cimma waɗannan burin, a cikin ƙirar PCB mai saurin gudu, ta hanyar ƙirar rami muhimmin abu ne.

Ta hanyar rami muhimmin abu ne a cikin ƙirar PCB mai ɗimbin yawa, rami ya ƙunshi sassa uku, ɗayan shine rami; Na biyu shine yankin kushin kusa da ramin; Na uku, yankin kadaici na WUTA Layer. Tsarin ramin shine a ɗora wani ƙarfe a saman silinda na bangon ramin ta hanyar sanya sinadarai don haɗa murfin jan ƙarfe wanda ke buƙatar haɗawa a cikin tsakiyar. Manyan da ƙananan bangarorin ramin an yi su da sifar gama -gari, wanda za a iya haɗa shi kai tsaye tare da babba da ƙananan ɓangarorin layin, ko ba a haɗa su ba. Ta hanyar ramuka ana iya amfani da su don haɗin lantarki, gyarawa ko sakawa na’urori.

PCB mai saurin gudu ta hanyar ƙirar rami

Ta ramuka gabaɗaya an kasu kashi uku: makafi rami, ramin binne da rami.

Makafi rami: rami wanda ke saman saman da kasa na allon da’irar da aka buga tare da wani zurfin don haɗa da’irar farfajiya zuwa da’irar ciki a ƙasa. Zurfin ramin yawanci baya wuce adadin ramin.

Ramin da aka binne: ramin haɗi a cikin layin ciki na allon da’irar da aka buga wanda baya kaiwa zuwa saman allon da’irar da aka buga.

Makafin rami da ramin da aka binne iri biyu na ramuka suna a cikin sashin ciki na allon kewaye, laminating ta amfani da tsarin gyaran rami don kammalawa, a cikin tsarin samuwar kuma yana iya haɗawa da yadudduka da yawa na ciki.

Ramin-ramukan da ke gudana cikin dukkan allon kewaye kuma ana iya amfani da su don haɗin haɗin ciki ko azaman hawa da gano ramuka don abubuwan haɗin gwiwa. Saboda ramin rami a cikin tsari yana da sauƙin cimmawa, farashin ya yi ƙasa, don haka ana amfani da babban allon da’irar da aka buga.
