4 Layer ENIG FR4 Heavy Copper PCB
Heavy Copper PCB
Heavy copper PCB mabhodhi anogona kugadzirwa zviri nyore nekubatanidzwa kwemaitiro maviri makuru, electroplating uye etching.Kusiyana nemamwe maPCBS, dunhu rakagadzirwa nehutete hwakatsetseka hwemhangura foil.
Iyo inorema yemhangura maPCB akafananidzwa laminated neFR4 kana imwe epoxy-based material.Huwandu hwehuremu hwePCB dzemhangura dzinorema hunogona kuita maounzi mana (140μm), iri reshiyo iri nani pane imwe PCB yemhangura yakajairika.
Iyo yekuwedzera yemhangura ukobvu inobvumira bhodhi kuti riite yakakwira mafungu, kuwana yakanaka kugovera kupisa, uye kugonesa kuchinjika kwakaoma munzvimbo shoma.Zvimwe zvakanakira zvinosanganisira kuwedzera simba remagetsi panzvimbo dzekubatanidza, kugona kugadzira zvidiki zvidiki zvechigadzirwa nekubatanidza huremu hwakawanda muchikamu chimwe chete chedunhu, uye kugona kushandisa zvigadzirwa zvine hunyanzvi zvine njodzi shoma yekutadza kwedunhu.
Benefits Of Heavy Copper PCB
Kugadzirwa kwePCB yemhangura inorema kunosanganisira kushandiswa kweplating kana etching, sezvo ichiwedzera ukobvu hwemhangura PCB mumadziro emadziro uye maburi ekuisa.Uye zvakare, inorema mhangura PCBS inoiswa electroplated panguva yekugadzira PCB.Izvi zvinobatsira kuomesa madziro ePTH paPCB.Mamwe maitiro ePCBS gobvu yemhangura akasiyana kubva kune mamwe maPCBS anosanganisira:
Huremu hweMhangura:
Ichi ndicho chokwadi chinhu chikuru chePCB inorema yemhangura.Rinoreva huremu hwemhangura hunoshandiswa paskweya tsoka mumaonzi.
Cover
Outer copper foil.Huremu hwemhangura hwekunze kwekunze ndeye dhizaini yakagadzikwa pamberi.
Inner Layer
Hunhu hwemhangura uye dielectric ukobvu hwemukati wemukati zvinhu zvakafanotsanangurwa zvakajairwa.Nekudaro, ivo vanogona kuchinjirwa kune zvakajairwa zvinodiwa zvepurojekiti.
Kushandiswa kweHeavy Copper PCB
Heavy copper PCBs anoshandiswa mumhando dzakasiyana-siyana, dzakadai seflat transformers, kupararira kwekushisa, kupararira kwemasimba makuru, kushandura kushandura, nezvimwewo. MuPC, motokari, mauto uye mechanical control, kufarira mumhangura yakawanda yakaputirwa ndiro iri kukura.Heavy copper yakadhindwa edunhu mabhodhi anoshandiswawo zvakanyanya:
1. Simba rekupa uye control converter
2. Chiremera chemari
3. Welding zvishandiso kana midziyo
4. Indasitiri yemotokari
5. Vagadziri vemagetsi ezuva, nezvimwewo
