Mabhodhi Edunhu Anoshanda Sei

Mabhodhi edunhu, anowanzo kunzi Printed Circuit Boards (PCBs), ndiwo ekutanga zvinhu mumidziyo yemagetsi yemazuva ano. Aya mabhodhi anoshanda semapuratifomu emuviri panoiswa zvinhu zvakasiyana-siyana zvemagetsi uye zvakabatana. Chaizvoizvo, ivo vanogadzira 'uropi' hwechero mudziyo wemagetsi, zvichiita kuti kubatanidzwa kwezvikamu zvakasiyana zvishande pamwechete zvisina musono. Kubva pamagajeti emazuva ese sema smartphones nemakomputa kusvika kune yakaoma masisitimu mumaindasitiri emotokari uye aerospace, mabhodhi edunhu akakosha pakupa zvivakwa zvinodiwa zvekubatanidza magetsi uye kushanda.

Chimiro Chikuru cheDare Redunhu

Chimiro chebhodhi redunhu chakakosha pakushanda kwayo. Papakati payo pane substrate, inowanzo gadzirwa nezvinhu zvakaita sefiberglass, inopa rutsigiro rwemuchina. Pane iyi substrate, maitirwo emhangura anoitisa akaiswa kugadzira nzira dzezviratidzo zvemagetsi. Aya maronda anobatanidza zvikamu zvakasiyana-siyana pabhodhi, zvichivabvumira kutaurirana uye kushanda pamwe chete. Pamusoro pezvo, mabhodhi edunhu anogona kunge aine akaturikidzana akawanda, kunyanya mumagetsi akaomarara, ane zvidimbu zvemukati zvekugovera simba uye chiratidzo chekufambisa. Dhizaini yeaya maronda uye akaturikidzana akarongwa zvine hungwaru kuti ave nechokwadi chekushanda kwakakwana kwechigadzirwa chemagetsi.

Zvikamu Zvinokosha paBhodhi Redunhu

Resistors

Resistors inodzora kuyerera kwemagetsi emagetsi mukati medunhu, kudzivirira kukuvadzwa kwezvinhu zvinonzwisisika nekudzikamisa ikozvino.

Capacitors

Macapacitors anochengetedza uye anoburitsa simba remagetsi, achibatsira kudzikamisa voltage uye magetsi mukati medunhu.

Yakabatanidzwa Matunhu (ICs)

ICs, inozivikanwawo semamicrochips, masekete akaomarara akave akadhindwa padiki chip. Vanogona kuita mabasa akasiyana-siyana, zvichienderana nekugadzirwa kwavo, kubva pakugadzirisa data kusvika kukusimudzira zviratidzo.

Diodes uye Transistors

Diodes inobvumira ikozvino kuyerera munzira imwe chete, nepo transistors ichiita sema switch kana amplifiers mudunhu.

Zvibatanidza uye Sockets

Izvi zvikamu zvinoshandiswa pakubatanidza bhodhi redunhu kune zvigadzirwa zvekunze kana zvitubu zvemagetsi.

Sei Circuit Boards Channel Magetsi

Mabhodhi edunhu anoshanda semikoto yemagetsi mumidziyo yemagetsi. Matekisheni emhangura anoitisa akaiswa pabhodhi anogadzira nzira dzinotungamira mafambiro emagetsi. Idzi nzira dzakagadzirwa zvine hungwaru kuti dzibatanidze zvinhu zvakasiyana-siyana senge resistors, capacitors, uye microchips mune chaiyo kurongeka uye maitiro. Uku kuyerera kwemagetsi kwakarongeka ndiko kunobvumira bhodhi redunhu kuita mabasa akaomarara, kubva pakugadzirisa data mukombuta kusvika pakudzora microwave mukicheni yako. Chaizvoizvo, bhodhi redunhu rinoona kuti magetsi anosvika pazvikamu zvakafanira panguva chaiyo, zvichiita kuti mudziyo ushande sezvaunotarisirwa.

Maitiro Ekugadzira Dare Redunhu

Dhizaini uye Kurongeka

Nhanho yekutanga kugadzira dhizaini bhodhi marongero uchishandisa CAD software. Izvi zvinosanganisira kuisa zvikamu uye nzira dzekufambisa kuti dzigadzire kubatanidza magetsi.

Kugadzira Bhodhi

Iyo dhizaini inozoendeswa kune yemhangura-yakapfeka substrate, uye iyo isingadiwe mhangura inoiswa kure kuti igadzire traces. Multiple layers inogona kuve yakashongedzwa pamwe chete kana iri multilayer board.

Chikamu Gungano

Zvigadzirwa zvemagetsi zvakaiswa pabhodhi, kungave kuburikidza nepamusoro-mounzi tekinoroji (SMT) kana kuburikidza-gomba tekinoroji, zvichienderana nedhizaini.

Kuedzwa uye Kuvimbiswa Kwemhando

Pakupedzisira, bhodhi redunhu rakapedzwa rinoedzwa kushanda uye kunaka, kuve nechokwadi kuti rinosangana nezvose zvakatemwa.

Mabhodhi edunhu akakosha mumagetsi emazuva ano, akanyatso kugadzirwa kuti atarise uye atungamirire magetsi ekushanda kwemidziyo yemagetsi.

Mhando dzeMabhodhi Edunhu uye Mashandisirwo Awo

Kune marudzi akati wandei emabhodhi edunhu, rimwe nerimwe rakagadzirirwa maapplication chaiwo. Mhando dzinonyanyozivikanwa dzinosanganisira:

Single-Layer PCBs

Aya ndiwo marudzi akareruka emapuranga ematunhu, ane zvikamu zvakasungirirwa kune rumwe rutivi uye mitsara yemhangura kune imwe. Iwo anoshandiswa zvakanyanya mumutengo wakaderera wevatengi zvemagetsi sema calculator uye ma LED ekuvhenekesa masisitimu.

Multilayer PCBs

Multilayer PCBs ine akawanda akaturikidzana e substrate nemhangura, yakamisikidzwa pamwechete. Iwo anoshandiswa mumagetsi akaomarara akadai sema smartphones, maseva, uye maindasitiri emidziyo nekuda kwekugona kwavo kutsigira yakakwirira-density dhizaini uye yakakwirira-yekumhanya chiratidzo chekufambisa.

Rigid-Flex PCBs

Kubatanidza matekinoroji ebhodhi rakaomarara uye rinochinjika, maPCB anochinjika-chinjika akagadzirirwa mashandisirwo anoda kugara kwenguva refu uye kuchinjika, senge mumidziyo yekurapa, makamera, uye zvishandiso zvemuchadenga.

Nei Circuit Board Dhizaini Inobata Mukuita Kwechigadzirwa

Dhizaini yebhodhi redunhu inodarika zvikamu zvekubatanidza; zvinokanganisa zvakananga kuvimbika kwechigadzirwa, kuita, uye hupenyu. Yakashata PCB dhizaini inogona kukonzeresa kukanganiswa kwechiratidzo, kupisa, kana kutadza zvachose system.

Semuyenzaniso, kutadza kutevedza nzira kunogona kukonzera kuderedzwa kwechiratidzo mumaseketi ekumhanya edhijitari. Mumagetsi emagetsi, kusakwana kwemhangura ukobvu kana kushata kwemafuta ekupisa kunogona kutungamirira kunzvimbo dzinopisa, kuderedza kushanda uye kuchengetedzeka kwechigadzirwa.

Naizvozvo, kuinjiniya bhodhi redunhu nekutarisa kurongeka, kutungamira kwekupisa, uye kutendeseka kwechiratidzo kwakakosha, kunyanya kune-yakakosha mashandisiro akaita seaerospace, mota, uye michina yekurapa.
