Foiri yemhangura yePCB

Nekuda kwekushandiswa kwakawanda kwemidziyo yemagetsi, kudiwa kwemidziyo iyi kwagara kuri kukuru pamusika. Midziyo iyi parizvino yakatikomberedza sezvo tichivimba nayo zvakanyanya kune zvinangwa zvakasiyana. Nekuda kweizvi, ndinofunga kuti wakasangana nemudziyo wemagetsi kana kuti unowanzoishandisa kumba. Kana ukashandisa michina iyi, ungashamisika kuti zvikamu zvemidziyo yemagetsi zvakagadzirwa sei netambo, kuti zvinoshanda sei, uye kuti mudziyo wacho ungabatanidzwa sei nezvimwe zvinhu. Midziyo yemagetsi yatinoshandisa kumba yakagadzirwa nezvinhu zvisingafambise magetsi. Ine nzira dzakacherwa nezvinhu zvemhangura zvinofambisa magetsi pamusoro payo, zvichibvumira chiratidzo kuti chifambe mukati memudziyo kana uchishanda.

Saka, tekinoroji yePCB yakavakirwa pakunzwisisa mashandiro emidziyo yemagetsi. PCB inogara ichishandiswa zvakanyanya mumidziyo yemagetsi yakagadzirirwa midhiya. Zvisinei, muchizvarwa chemazuva ano, inoshandiswa mumidziyo yese yemagetsi. Nekuda kweizvi, hapana mudziyo wemagetsi unogona kushanda pasina PCB. Iyi blog inotarisa pane copper foil yePCB, uye basa rinoitwa nefoil yemhanguramuindasitiri yebhodhi redunhu.

Tekinoroji yePrinted Circuit Board (PCB)

MaPCB ndiwo nzira dzinofambisa magetsi dzakadai sematracks nematracks, ayo akafukidzwa necopper foil. Izvi zvinoita kuti abatane uye atsigire zvimwe zvikamu zvemagetsi zvakabatana nekanika kune mudziyo. Nekuda kweizvi, basa guru remaPCB aya mumidziyo yemagetsi nderekutsigira nzira. Kazhinji, zvinhu zvakaita sefiberglass nemapurasitiki zvinobata copper foil zviri nyore mucircuit. Copper foil iri muPCB inowanzo sungirirwa ne non-conductive substrate. MuPCB, copper foil inoita basa rakakosha mukubvumira kufamba kwemagetsi pakati pezvikamu zvakasiyana zvemudziyo, nokudaro zvichitsigira kutaurirana kwavo.

Masoja anogara achibatanidza zvinobudirira pakati pePCB nemidziyo yemagetsi. Ma solder aya anogadzirwa nesimbi inoita kuti ive namati yakasimba; saka, akavimbika mukupa rutsigiro rwemakanika kuzvikamu zvacho. Nzira yePCB inowanzo sanganiswa nezvinhu zvakasiyana-siyana zvakaita se silkscreen nesimbi dzakanamirwa ne substrate kuti dzive PCB.

Basa re copper foil muindasitiri ye circuit board

Tekinoroji itsva iri kufarirwa mazuva ano zvinoreva kuti hapana mudziyo wemagetsi unogona kushanda usina PCB. PCB, kune rumwe rutivi, inovimba zvakanyanya nemhangura kupfuura zvimwe zvikamu. Izvi zvinodaro nekuti mhangura inobatsira kugadzira madonhwe anobatanidza zvikamu zvese muPCB kuti zvibvumire kufamba kwechaja mukati memudziyo. Madonhwe acho anogona kutsanangurwa setsinga dzeropa dziri mumafupa ePCB. Saka PCB haigone kushanda kana madonhwe acho asipo. Kana PCB ikatadza kushanda, mudziyo wemagetsi unorasikirwa nepfungwa yawo, zvichiita kuti usashande. Naizvozvo, mhangura ndiyo chikamu chikuru chekufambisa simba chePCB. Foil yemhangura iri muPCB inoita kuti zviratidzo zvirambe zvichifamba pasina kukanganiswa.

Zvinhu zvemhangura zvinogara zvichizivikanwa kuti zvine simba rekufambisa mhepo kupfuura zvimwe zvinhu nekuda kwemaerekitironi akasununguka ari mugoko rayo. Maerekitironi akasununguka kufamba pasina kupikiswa neatomu chero ipi zvayo inoita kuti mhangura ikwanise kutakura magetsi anofamba zvakanaka pasina kurasikirwa kana kukanganiswa kwezviratidzo. Mhangura, iyo inogadzira electrolyte isina kunaka yakakwana, inogara ichishandiswa mumaPCB sechikamu chekutanga. Nekuti mhangura hainyanyi kukanganiswa neokisijeni yepamusoro, inogona kushandiswa nemhando dzakasiyana dzesubstrates, insulating layers, uye simbi. Kana ikashandiswa nesubstrates idzi, inoumba mapatani akasiyana mudunhu, kunyanya mushure mekuchekwa. Izvi zvinogoneka nguva dzose nekuda kwekugona kwemhangura kuita chisungo chakakwana neinsulating layers dzinoshandiswa kugadzira PCB.

Kazhinji pane zvikamu zvitanhatu zvePCB zvinogadzirwa, uye zvikamu zvina zviri muPCB. Zvimwe zvikamu zviviri zvinowanzowedzerwa kune inner panel. Nekuda kweizvi, zvikamu zviviri izvi ndezvekushandisa mukati, kunewo zviviri zvekushandisa kunze, uye pakupedzisira, zvikamu zviviri zvasara kubva pamatanhatu ese ndezvekuvandudza mapaneru mukati mePCB.

Mhedziso

Foyi yemhangurachikamu chakakosha chePCB chinobvumira kuyerera kwemagetsi pasina kukanganiswa. Ine conductivity yakakwira uye inogadzira chisungo chakasimba nezvinhu zvakasiyana-siyana zvinodzivirira zvinoshandiswa mubhodhi rePCB. Nekuda kweizvi, PCB inoshandisa foil yemhangura kuti ishande sezvo ichiita kuti kubatana kwePCB skeleton kushande.
