Metal base copper clad plate ndi FR-4 ndi magawo awiri omwe amagwiritsidwa ntchito kwambiri pamakampani amagetsi. Amasiyana mu kapangidwe kazinthu, mawonekedwe amachitidwe ndi magawo ogwiritsira ntchito. Lero, Fastline ikupatsirani kuwunika kofananira kwa zida ziwirizi kuchokera pamalingaliro aukadaulo:

Chitsulo chovala chachitsulo chachitsulo: Ndizinthu zachitsulo za PCB, nthawi zambiri zimagwiritsa ntchito aluminiyamu kapena mkuwa ngati gawo lapansi. Mbali yake yaikulu ndi yabwino matenthedwe madutsidwe ndi kutentha dissipation mphamvu, choncho ndi otchuka kwambiri ntchito amafuna mkulu matenthedwe madutsidwe, monga kuwala kwa LED ndi converters mphamvu. Gawo lachitsulo lachitsulo limatha kuyendetsa bwino kutentha kuchokera kumalo otentha a PCB kupita ku bolodi lonse, motero kuchepetsa kutentha ndi kupititsa patsogolo ntchito yonse ya chipangizocho.

FR-4: FR-4 ndi laminate chuma ndi galasi CHIKWANGWANI nsalu monga kulimbikitsa zinthu ndi epoxy utomoni monga binder. Pakali pano ndi gawo laling'ono la PCB lomwe limagwiritsidwa ntchito kwambiri, chifukwa cha mphamvu zake zamakina abwino, zida zotchinjiriza zamagetsi komanso zoletsa moto ndipo zimagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zamagetsi. FR-4 ili ndi UL94 V-0 yobwezeretsanso moto, zomwe zikutanthauza kuti imayaka pamoto kwakanthawi kochepa kwambiri ndipo ndiyoyenera kugwiritsidwa ntchito pazida zamagetsi zomwe zili ndi chitetezo chachikulu.

kusiyana kwakukulu:

Zida zam'munsi: Zitsulo zovala zamkuwa zimagwiritsa ntchito zitsulo (monga aluminiyamu kapena mkuwa) ngati gawo lapansi, pomwe FR-4 imagwiritsa ntchito nsalu za fiberglass ndi epoxy resin.

Thermal conductivity: Thermal conductivity of the iron clad sheet ndi apamwamba kwambiri kuposa a FR-4, omwe ndi oyenera ntchito zomwe zimafuna kutayika kwabwino kwa kutentha.

Kulemera ndi makulidwe: Mapepala amkuwa ovala zitsulo nthawi zambiri amakhala olemera kuposa FR-4 ndipo amatha kukhala owonda.

Kuthekera kwa njira: FR-4 ndiyosavuta kuyikonza, yoyenera pamapangidwe a PCB osanjikiza ambiri; Chitsulo chovala mbale yamkuwa ndizovuta kukonza, koma ndizoyenera kusanjikiza chimodzi kapena zingapo zosavuta kupanga.

Mtengo: Mtengo wa pepala lovala zitsulo nthawi zambiri umakhala wokwera kuposa FR-4 chifukwa chamtengo wapamwamba wachitsulo.

Ntchito: Zitsulo zovala zamkuwa zimagwiritsidwa ntchito makamaka pazida zamagetsi zomwe zimafuna kutentha kwabwino, monga magetsi amagetsi ndi kuyatsa kwa LED. FR-4 ndi yosunthika kwambiri, yoyenera pazida zamagetsi zambiri komanso mapangidwe a PCB amitundu yambiri.

Nthawi zambiri, kusankha kwachitsulo chovala kapena FR-4 makamaka kumadalira zosowa zamafuta azinthu, zovuta zamapangidwe, bajeti yamtengo wapatali komanso zofunikira zachitetezo.
