Copper foil yePCB

Nekuda kwekuwedzera kwekushandiswa kwemidziyo yemagetsi, kudiwa kwemidziyo iyi kwagara kwakakwira pamusika. Midziyo iyi parizvino inotitenderedza sezvo isu tinovimba nayo zvakanyanya nezvinangwa zvakasiyana. Nechikonzero ichi, ini ndinobheja kuti wakasangana nemudziyo wemagetsi kana kuti unowanzo shandisa kumba. Kana iwe ukashandisa midziyo iyi, unogona kushamisika kuti zvikamu zvemagetsi zvemagetsi zvakabatanidzwa sei, kuti zvinoshanda sei, uye kuti mudziyo unogona kubatanidzwa sei kune zvimwe zvinhu. Midziyo yemagetsi yatinoshandisa kumba inogadzirwa nezvinhu zvisingaite magetsi. Ivo vane nzira dzakatemerwa ne conductive mhangura zvinhu pamusoro pavo, zvichibvumira chiratidzo kuti chiyerere mukati memudziyo kana chiri kushanda.

Naizvozvo, tekinoroji yePCB yakavakirwa pakunzwisisa kushanda kwemidziyo yemagetsi. Iyo PCB inogara ichishandiswa zvakanyanya mumidziyo yemagetsi yakagadzirirwa midhiya. Zvisinei, muchizvarwa chemazuva ano, dzinoshandiswa mune zvose zvigadzirwa zvemagetsi. Nechikonzero ichi, hapana mudziyo wemagetsi unogona kushanda usina PCB. Iyi blog inotarisa pane yemhangura foil yePCB, uye basa rinoitwa nefoil yemhanguramuindasitiri yedunhu rebhodhi.

Iyo Yakadhindwa Circuit Board (PCB) Technology

MaPCB ndiwo magwara anofambiswa nemagetsi akadai semakwara nemakwara, ayo akaiswa laminated nefoiri yemhangura. Izvi zvinoita kuti vabatane uye vatsigire zvimwe zvikamu zvemagetsi zvakabatanidzwa nemichina kune mudziyo. Nechikonzero ichi, basa guru rePCB idzi mumidziyo yemagetsi nderekupa rutsigiro kumakwara. Kazhinji, zvinhu zvakaita sefiberglass nemapurasitiki zvinobata zviri nyore foil yemhangura mudunhu. Iyo foil yemhangura muPCB inowanzoiswa laminated ne-non-conductive substrate. MuPCB, foil yemhangura inoita basa rakakosha mukubvumira kuyerera kwemagetsi pakati pezvikamu zvakasiyana zvechigadzirwa, nekudaro vachitsigira kutaurirana kwavo.

Masoja anogara achibatana zvinobudirira pakati pePCB pamusoro uye zvigadzirwa zvemagetsi. Aya masoja anogadzirwa achishandisa simbi inoita kuti inamire yakasimba; saka, ivo vanovimbika mukupa rutsigiro rwemuchina kune zvikamu. Iyo PCB nzira inowanzoitwa compost ine akawanda akaturikidzana ezvakasiyana zvinhu senge silkscreen uye simbi dzakanamwa ne substrate kuti dziite PCB.

Basa remhangura foil mune redunhu bhodhi indasitiri

Tekinoroji nyowani inofamba nhasi zvinoreva kuti hapana mudziyo wemagetsi unogona kushanda usina PCB. Iyo PCB, kune rumwe rutivi, inotsamira pane yakawanda pamhangura kupfuura zvimwe zvikamu. Izvi zvinodaro nekuti mhangura inobatsira kugadzira zviteshi zvinobatanidza zvese zviri muPCB kubvumira kuyerera kwechaji mukati memudziyo. Iwo maronda anogona kutsanangurwa setsinga dzeropa dziri muskeleton yePCB. Saka iyo PCB haigone kushanda kana maronda asipo. Kana PCB ikatadza kushanda, mudziyo wemagetsi unorasa pfungwa, uchiita kuti ushaye basa. Naizvozvo, mhangura ndiyo huru conductivity chikamu chePCB. Iyo foil yemhangura muPCB inova nechokwadi chekugara kuyerera kwezviratidzo pasina kukanganisa.

Iyo mhangura yemhangura inogara ichizivikanwa kuti ine yakakwirira conductivity pane zvimwe zvinhu nekuda kwemahara maerekitironi aripo mugoko rayo. Maerekitironi akasununguka kufamba pasina kupokana nechero atomu inogadzira mhangura inokwanisa kutakura machaji emagetsi anofamba zvakanaka pasina kurasikirwa kana kukanganisa mumasaini. Iyo mhangura, iyo inogadzira yakakwana yakaipa electrolyte, inogara ichishandiswa muPCB seyekutanga layer. Nekuti mhangura hainyanyi kukanganiswa neokisijeni yepamusoro, inogona kushandiswa nemhando dzakasiyana dze substrates, insulating layer, uye simbi. Kana ichishandiswa neaya ma substrates, inoumba mapatani akasiyana mudunhu, kunyanya mushure mekucheka. Izvi zvinogara zvichigoneka nekuda kwekugona kwemhangura kugadzira chisungo chakakwana nematanho anodzivirira anoshandiswa kugadzira PCB.

Panowanzova nezvikamu zvitanhatu zvePCB zvinogadzirwa, kunze kwezvikamu zvina zviri muPCB. Mamwe maviri akaturikidzana anowanzowedzerwa kune yemukati panel. Nechikonzero ichi, iwo maviri akaturikidzana ndeekushandisa mukati, kune zvakare maviri ekushandiswa kwekunze, uye pakupedzisira, maviri asara kubva pamatanho matanhatu ese ndeekuwedzera mapaneru mukati mePCB.

Mhedziso

Copper foilchinhu chakakosha chePCB chinobvumira kuyerera kwemagetsi kuchaja pasina kukanganisa. Iyo ine yakakwirira conductivity uye inonyatso gadzira chisungo chakasimba chine zvakasiyana insulating zvinhu zvinoshandiswa muPCB redunhu bhodhi. Nechikonzero ichi, PCB inovimba nemhangura foil kuti ishande sezvo ichiita kuti kubatana kwePCB skeleton kushande.
