Nezvikonzero zvakawanda, kune akawanda akasiyana marudzi ePCB ekugadzira mapurojekiti anoda chaiwo huremu hwemhangura. Isu tinogashira mibvunzo kubva kune vatengi vasina kujairana nepfungwa yehuremu hwemhangura nguva nenguva, saka chinyorwa ichi chine chinangwa chekugadzirisa matambudziko aya. Mukuwedzera, zvinotevera zvinosanganisira ruzivo pamusoro pemigumisiro yezviyero zvakasiyana-siyana zvemhangura pamusangano wePCB, uye tinotarisira kuti ruzivo urwu ruchabatsira kunyange kune vatengi vanotoziva nezvepfungwa. Kunzwisisa kwakadzama kwemaitiro edu kunogona kuita kuti iwe ugone kuronga zvirinani chirongwa chekugadzira uye mutengo wakazara.
Iwe unogona kufunga nezvehuremu hwemhangura sehupamhi kana kukwirira kwemhangura yemhangura, iyo ndiyo yechitatu iyo iyo mhangura yemhangura data yeGerber file haina kufunga. Chiyero chechiyero maounces paskweya tsoka (oz / ft2), apo 1.0 oz yemhangura inoshandurwa kuita hukobvu hwe140 mils (35 μm).
Heavy copper PCBs inowanzo shandiswa mumagetsi emagetsi emagetsi kana chero midziyo inogona kutambura kubva munzvimbo dzakaomarara. Mateki akakora anogona kupa kusimba kwakakura, uye anogona zvakare kugonesa iyo trace kutakura yakawanda ikozvino pasina kuwedzera hurefu kana hupamhi hweiyo trace kusvika padanho risinganzwisisike. Kune rumwe rutivi rweequation, huremu hwemhangura hwakareruka dzimwe nguva hunotsanangurwa kuti uwane imwe trace impedance pasina kudiwa kwehurefu hwakanyanya hudiki kana hupamhi. Nokudaro, kana uchiverenga hupamhi hwekutsvaga, "huremu hwemhangura" inzvimbo inodiwa.
Iyo inonyanya kushandiswa huremu hwemhangura ndeye 1.0 ounce. Yakwana, yakakodzera kune akawanda mapurojekiti. Muchinyorwa chino, zvinoreva kuisa huremu hwemhangura hwekutanga kune yakakwira kukosha panguva yePCB yekugadzira maitiro. Paunenge uchitsanangura iyo inodiwa huremu hwemhangura kune timu yedu yekutengesa, ndapota ratidza iyo yekupedzisira (yakapfatwa) kukosha kwehuremu hunodiwa hwemhangura.
Makobvu emhangura maPCB anoonekwa sePCB ane kunze uye mukati memhangura ukobvu kubva pa3 oz/ft2 kusvika 10 oz/ft2. Huremu hwemhangura yePCB inorema yemhangura yakagadzira kubva pamaonzi mana paskweya tsoka kusvika pamakumi maviri paskweya tsoka. Iyo yakagadziridzwa huremu hwemhangura, yakasanganiswa neyakakora yeplating layer uye yakakodzera substrate mune kuburikidza negomba, inogona kushandura isina simba redunhu bhodhi kuita yakasimba uye yakavimbika wiring chikuva. Heavy copper conductor ichawedzera zvakanyanya kukora kwePCB yese. Ukobvu hwemhangura hunofanira kugara uchitariswa panguva yedunhu rekugadzira danho. Ikozvino kutakura kugona kunotarirwa nehupamhi uye ukobvu hwemhangura inorema.
Huremu hwepamusoro hwemhangura haizongowedzera mhangura pachayo, asiwo inokonzera humwe huremu hwekutakura uye nguva inodiwa yekushanda, maitiro ekugadzira, uye kuvimbiswa kwehutano, zvichiita kuti kuwedzerwa mari uye nguva yekuendesa. Kutanga, aya matanho ekuwedzera anofanirwa kutorwa, nekuti iyo yekuwedzera copper yemhangura pane laminate inoda nguva yakawanda yekuisa uye inofanirwa kutevedzera chaiyo DFM nhungamiro. Huremu hwemhangura hwebhodhi redunhu hunokanganisawo mashandiro ayo ekupisa, zvichiita kuti bhodhi redunhu ritore kupisa nekukurumidza panguva yereflow soldering nhanho yePCB musangano.
Kunyangwe pasina tsananguro yakajairwa yemhangura inorema, inogamuchirwa kuti kana 3 ounces (oz) kana kupfuura yemhangura yakashandiswa mukati nekunze kwemukati medhindi redunhu bhodhi, inonzi PCB inorema yemhangura. Chero dunhu rine hukobvu hwemhangura hunodarika 4 ounces paskweya tsoka (ft2) zvakare inorongedzerwa sePCB inorema yemhangura. Mhangura yakanyanyisa inoreva 20 kusvika ku200 ounces paskweya tsoka.
Kubatsira kukuru kwemapuranga emhangura inorema ndiko kugona kwavo kutsungirira kutarisana nemhepo yakawandisa, tembiricha yakakwira uye inodzokororwa kutenderera kwemafuta, izvo zvinogona kuparadza akajairika edunhu mabhodhi mukati memasekondi mashoma. Iyo inorema mhangura ndiro ine yakakwirira kutakura simba, iyo inoita kuti ienderane nezvikumbiro pasi pemamiriro akaomarara, akadai sekudzivirira uye aerospace indasitiri zvigadzirwa. Mamwe mabhenefiti einorema mhangura yedunhu mabhodhi anosanganisira:
Nekuda kwehuremu hwakawanda hwemhangura pane imwechete yedunhu layer, saizi yechigadzirwa inokwana
Mhangura inorema yakaputirwa nemakomba inopfuudza yakakwira ikozvino kuburikidza nePCB uye inobatsira kuendesa kupisa kune yekunze kupisa singi.
Airborne high power density planar transformer
Heavy mhangura akadhindwa redunhu mapuranga anogona kushandiswa nokuda kwezvinangwa zvakawanda, zvakadai semapurani emagetsi, kupisa kupisa, kugovera simba guru, magetsi ekushandura, nezvimwewo. Kudiwa kwemapuranga anorema emhangura akavharidzirwa mumakombiyuta, motokari, mauto, uye kutonga kwemaindasitiri kuri kuramba kuchikura. Heavy copper yakadhindwa edunhu mabhodhi anoshandiswawo kune:
Magetsi
Kuendeswa kwemagetsi
Welding midziyo
Automobile industry
Vagadziri ve solar panel, nezvimwe.
Zvinoenderana nezvinodiwa nedhizaini, mutengo wekugadzira wePCB inorema yemhangura wakakwira kupfuura yeyakajairika PCB. Naizvozvo, iyo yakanyanya kuoma dhizaini, inokwira mutengo wekugadzira inorema yemhangura PCB.
