Nyika yetekinoroji inogara ichishanduka uye pamwe nayo kudiwa kwemamwe epamberi uye akaomesesa akadhindwa edunhu mabhodhi (PCBs). PCBs chikamu chakakosha chemidziyo yemagetsi uye inoita basa rakakosha mukuona kushanda kwayo.Kuzadzisa kudiwa kuri kukura, vagadziri vanofanirwa kuongorora akakosha maitiro uye matekinoroji, senge bofu kuburikidza nemavharo emhangura, kuwedzera PCB mashandiro. Mune ino blog post, isu tichaongorora mikana yekushandisa aya akakosha maitiro muPCB kugadzira.
MaPCB anonyanya kugadzirwa uchishandisa zvidimbu zvemhangura dzakamisikidzwa kune isiri-conductive substrate, iyo inowanzo umbwa nefiberglass-reinforced epoxy.Aya maturu akaiswa kuti agadzire anodiwa magetsi ekubatanidza uye zvikamu pabhodhi. Nepo iyi yechinyakare gadziriro yekugadzira inoshanda kune akawanda maapplication, mamwe mapurojekiti angangoda mamwe maficha uye mashandiro asingagoneke kuburikidza nemaitiro echinyakare.
Imwe nzira yakasarudzika ndeyekubatanidza mapofu kuburikidza nemavharo emhangura muPCB.Mapofu vias vari vasiri-kuburikidza nemakomba kuti chete kuwedzera kune chaiwo kudzika mukati bhodhi pane zvachose kuburikidza bhodhi. Aya mabhofu vias anogona kuzadzwa nemhangura kuumba yakachengeteka yakabatana kana kuvharira zvinosiririsa zvinoriumba. Iyi tekinoroji inonyanya kubatsira kana nzvimbo ishoma kana nzvimbo dzakasiyana paPCB dzinoda mazinga akasiyana ekuita kana kudzivirira.
Imwe yemabhenefiti makuru emapofu kuburikidza nemhangura zvivharo ndeyekuwedzera kuvimbika.Iyo copper filler inopa yakagadziridzwa mekiniki rutsigiro kumadziro egomba, ichidzikisa njodzi yemaburrs kana yakadhirowa kukuvara kwegomba panguva yekugadzira. Uyezve, iyo mhangura yemhangura inopa yakawedzera kupisa conductivity, ichibatsira kubvisa kupisa kubva muchikamu, nekudaro ichiwedzera kuita kwayo kwese uye hupenyu hurefu.
Kune mapurojekiti anoda mapofu kuburikidza nemavhavha emhangura, hunyanzvi hwekushandisa uye tekinoroji inodiwa panguva yekugadzira.Uchishandisa michina yekuchera yepamusoro, maburi mapofu ehukuru hwakasiyana uye maumbirwo anogona kucherwa nemazvo. Michina iyi yakashongedzerwa nemasisitimu ekudzora echokwadi ayo anovimbisa mhedzisiro uye inovimbika. Pamusoro pezvo, maitiro acho angangoda matanho ekuchera akawanda kuti uwane kudzika kwaunoda uye chimiro chegomba rebofu.
Imwe nzira yakasarudzika mukugadzira PCB ndeyekuitwa kwekuvigwa vias.Akavigwa vias maburi anobatanidza akawanda akaturikidzana ePCB asi asingaendere kune ekunze akaturikidzana. Iyi tekinoroji inogona kugadzira yakaoma akawanda-layer maseketi pasina kuwedzera bhodhi saizi. Kuvigwa vias kunowedzera kushanda uye kuwanda kwePCBs, zvichiita kuti ive yakakosha kune zvemazuva ano zvigadzirwa zvemagetsi. Zvisinei, kushandisa vias akavigwa kunoda kunyatsoronga uye kugadzirwa chaiko, sezvo maburi anofanirwa kunyatsoenderana uye kudhirwa pakati pematanho chaiwo.
Iko kusanganiswa kwemaitiro akakosha mukugadzira PCB, senge bofu kuburikidza nemhangura inovhara uye yakavigwa vias, pasina mubvunzo inowedzera kuoma kwemaitiro ekugadzira.Vagadziri vanofanirwa kuisa mari mumidziyo yepamusoro, kudzidzisa vashandi muhunyanzvi hwehunyanzvi, uye kuona kuti matanho ekudzora emhando yepamusoro aripo. Nekudaro, mabhenefiti uye kugona kwakakwidziridzwa kunopihwa neaya maitiro anoita kuti atsoropodze kune mamwe maapplication, kunyanya ayo anoda yepamusoro wedunhu uye miniaturization.
Muchidimbu, maitiro akakosha ekugadzira PCB, akadai semapofu kuburikidza nemakapisi emhangura uye vias akavigwa, hazvigoneke chete asi zvinodiwa kune mamwe mapurojekiti.Aya maitiro anowedzera PCB mashandiro, kuvimbika, uye kuwanda, zvichiita kuti ive yakakodzera kune epamberi zvigadzirwa zvemagetsi. Kunyange ivo vachida imwe mari yekudyara uye yakasarudzika michina, ivo vanopa mabhenefiti anopfuura matambudziko. Sezvo tekinoroji ichienderera mberi, vagadziri vanofanirwa kufambirana neaya maitiro ehunyanzvi kusangana nekuchinja kuri kuita indasitiri.
