PCBs mune zvidiki-zvigadzirwa chikamu chakakosha chemazuva ano zvigadzirwa zvemagetsi.Ukobvu hwemhangura chinhu chakakosha muPCB kugadzira maitiro.Ukobvu hwakakodzera hwemhangura hunogona kuvimbisa kunaka uye kushanda kwebhodhi redunhu, uye zvakare kunokanganisa kuvimbika uye kugadzikana kwezvigadzirwa zvemagetsi.
Kazhinji, hukobvu hwedu hwemhangura hwakajairika 17.5um (0.5oz), 35um (1oz), 70um (2oz)
Ukobvu hwemhangura hunotaridza kufambiswa kwemagetsi kwebhodhi redunhu.Mhangura yakanakisa conductive zvinhu, uye ukobvu hwayo hunokanganisa zvakananga conductive mhedzisiro yedunhu redunhu.Kana iyo mhangura yemhangura yakanyanya kutetepa, iyo conductive zvivakwa inogona kuderera, zvichikonzera kuderedzwa kwechiratidzo chekufambisa kana kusagadzikana kwezvino.Kana mhangura yemhangura yakanyanyisa, kunyange iyo conductivity ichave yakanaka kwazvo, inowedzera mari uye uremu hwebhodhi redunhu.Kana iyo mhangura yemhangura yakawandisa, inotungamira nyore kune yakakomba glue kuyerera, uye kana iyo dielectric layer yakanyanya kutetepa, kuoma kwekugadzirisa kwedunhu kuchawedzera.Naizvozvo, 2oz mhangura ukobvu kazhinji haukurudzirwe.Mukugadzira PCB, ukobvu hwemhangura hwakakodzera hunoda kusarudzwa zvichibva pane zvinodiwa nedhizaini uye kushandiswa chaiko kwebhodhi redunhu kuti riwane yakanakisa conductive mhedzisiro.
Chechipiri, ukobvu hwemhangura zvakare hune simba rakakosha pakuita kwekupisa kwekupisa kwebhodhi redunhu.Sezvo zvigadzirwa zvemazuva ano zvemagetsi zvinowedzera uye zvakanyanya simba, kupisa kwakanyanya kunogadzirwa panguva yekushanda kwavo.Kushanda kwakanaka kwekupisa kupisa kunogona kuvimbisa kuti kutonhora kwezvikamu zvemagetsi kunodzorwa mukati mehutano hwakachengeteka panguva yekushanda.Iyo mhangura yemhangura inoshanda seyekupisa conductive layer yedunhu redunhu, uye ukobvu hwayo hunosarudza kupisa kwekupisa.Kana iyo mhangura yemhangura yakanyanya kuonda, kupisa hakugone kuitiswa uye kubviswa zvinobudirira, kuwedzera njodzi yezvikamu zvinopisa.
Naizvozvo, ukobvu hwemhangura hwePCB haugone kuonda.Munguva yePCB dhizaini maitiro, isu tinogona zvakare kuisa mhangura munzvimbo isina chinhu kuti tibatsire kupisa kupisa kwePCB board.Mukugadzira PCB, kusarudza kwakakodzera mhangura ukobvu kunogona kuve nechokwadi chekuti redunhu bhodhi rine kunaka kwekupisa kupisa.kushanda kuti kuve nechokwadi chekushanda kwakachengeteka kwezvikamu zvemagetsi.
Mukuwedzera, kukora kwemhangura kunewo zvakakosha pakuvimbika uye kugadzikana kwebhodhi redunhu.Iyo mhangura yemhangura haingoshandi seyemagetsi uye thermally conductive layer, asi inoshanda serutsigiro uye yekubatanidza dhizaini yedunhu bhodhi.Ukobvu hwakakodzera hwemhangura hunogona kupa simba rakakwana remagetsi kudzivirira bhodhi redunhu kubva pakukotama, kutyora kana kuvhura panguva yekushandiswa.Panguva imwecheteyo, ukobvu hwemhangura hwakakodzera hunogona kuve nechokwadi chemhando yewelding yebhodhi redunhu uye zvimwe zvikamu uye kuderedza njodzi yekuremara kwewelding uye kutadza.Naizvozvo, mukugadzira PCB, kusarudza kwakakodzera mhangura ukobvu kunogona kuvandudza kuvimbika uye kugadzikana kwebhodhi redunhu uye kuwedzera hupenyu hwebasa rezvigadzirwa zvemagetsi.
Kupfupisa, kukosha kwemhangura ukobvu muPCB kugadzira hakugone kufuratirwa.Iyo chaiyo mhangura ukobvu hunogona kuve nechokwadi chemagetsi conductivity, kupisa kupisa kuita, kuvimbika uye kugadzikana kwebhodhi redunhu.
Muchiitiko chaicho chekugadzira, zvinodikanwa kuti usarudze hukobvu hwakakodzera hwemhangura zvichibva pazvinhu zvakaita sedhizaini dhizaini zvinodiwa, zvinodiwa zvinoshanda, uye kudzora mutengo kuti uve nechokwadi chemhando uye kushanda kwezvigadzirwa zvemagetsi.Nenzira iyi chete inogona kugadzirwa maPCB emhando yepamusoro kuti asangane nekuita kwepamusoro uye kuvimbika kwepamusoro zvinodiwa zvemidziyo yemagetsi yemazuva ano.
