Kazhinji, ukobvu hwemhangura hwePCB yakajairwa ndeye 1oz kusvika 3oz. Makobvu-mhangura PCBs kana heavy-mhangura PCBs ndiwo marudzi PCBs kuti rakapedzwa mhangura uremu kupfuura 4oz (140μm) .Ikobvu mhangura inobvumira hombe PCB-muchinjika-zvikamu nokuda mukuru zvino mitoro uye anokurudzira kupisa dissipation. Madhizaini akajairika akawanda kana maviri-mativi. Neiyi tekinoroji yePCB zvinogoneka zvakare kusanganisa zvimiro zvakanaka zvemarongedzero pane ekunze akaturikidzana uye makobvu emhangura akaturikidzana mukati memukati.
Iyo gobvu-yemhangura PCB ndeyemhando yakakosha yePCB. ayo conductive zvinhu, substrate zvinhu, kugadzirwa muitiro, kushandiswa minda zvakasiyana kubva kwakajairika PCBs. Kuiswa kwemaseketi emhangura gobvu kunobvumira vagadziri vePCB kuti vawedzere huremu hwemhangura kuburikidza nemadziro emadziro uye maburi akaiswa, izvo zvinogona kuderedza nhamba yedhivha uye tsoka. Gobvu-mhangura plating inobatanidza yakakwirira-ikozvino uye kutonga maseketi, kuita yakakwirira-density ine nyore bhodhi zvimiro zvinogona kuwanikwa.
Kuvakwa kwe-heavy-copper circuits kunopa maPCBs anotevera:
1.Kuwedzera simba remazuva ano zvakanyanya
2.Kutsungirira kwepamusoro kune zvinopisa zvinopisa
3.Zviri nani kupisa kupisa
4.Kuwedzera simba remagetsi pazvibatanidza uye maburi
ePTH 5.Deredzai saizi yechigadzirwa.
Iko kushandiswa kwePCB dzakakora-mhangura
Pamwe chete nekuwedzera kwezvigadzirwa zvemagetsi, kudiwa kwePCB dzakakora-mhangura kunowedzerwa zvakanyanya. Vagadziri vePCB vanhasi vanotarisisa kushandisa bhodhi gobvu remhangura kugadzirisa kupisa kwemagetsi emagetsi emagetsi.
Iwo gobvu-mhangura PCBs anonyanya kukura azvino substrate, uye maPCB makuru aripo anonyanya kushandiswa mumagetsi module uye mota dzemagetsi zvikamu. Mota dzechinyakare, magetsi, uye magetsi emagetsi maapplication anoshandisa nzira dzekutanga dzekufambisa senge tambo yekugovera uye simbi pepa. Iye zvino mapuranga akakora-mhangura anotsiva fomu rekufambisa, iro risingagone kuvandudza zvibereko uye kuderedza nguva yemutengo we wiring, asiwo kuwedzera kuvimbika kwezvigadzirwa zvekupedzisira. Panguva imwecheteyo, mapuranga makuru emazuva ano anogona kuvandudza rusununguko rwekugadzira wiring, nokudaro kuona miniaturization yechigadzirwa chose.
Gobvu-mhangura redunhu PCB inoita basa risingadzokerike mumashandisirwo ane yakakwirira-simba, yakakwira ikozvino, uye yakanyanya kutonhora kudiwa. Iyo yekugadzira maitiro uye zvinhu zveheavy-mhangura PCBS zvine zvakanyanya kukwirira zvinodiwa kupfuura standard PCBs. Iine michina yemhando yepamusoro uye mainjiniya ehunyanzvi, YMS inopa gobvu-mhangura maPCB ane yepamusoro-soro kune vatengi vanobva kumba nekune dzimwe nyika.
