Waht ndeye SMD LED BT Substrate:

SMD LED BT Substrate inoreva iyo PBB iyo inogadzirwa neBT Zvishandiso uye inoshandiswa kune SMD LED zvigadzirwa.Zvakasiyana neyakajairwa pcb , BT Zvishandiso zvinoiswa muMD LED BT Substrate, iyo inonyanya kugadzirwa neMistubishi Gasi Chemical Co, Inc. Iyo BT Zvishandiso zvakagadzirwa neB (Bismaleimide) uye T (Triazine) resin ine zvakanakira yakakwira TG (255 ~ 330 ° C), kupisa kupisa (160 ~ 230 ° C), mwando kuramba, yakaderera dielectric nguva dzose (DK) uye yakaderera kuparara chinhu (Df). SMD LED ndiyo nyowani yepamusoro gomo semiconductor mwenje-inoburitsa chishandiso, ine diki yekuparadzira kona yakakura, yakafanana mwenje, kuvimbika kwakakwirira, mavara akareruka anosanganisira machena machena, inoshandiswa zvakanyanya mune akasiyana zvigadzirwa zvemagetsi. Pcb bhodhi ndeimwe yemhando huru yekugadzira SMD LED zvinhu.

Musiyano b etween SMD uye COB LED

SMD inoreva izwi rekuti "Surface Yakakwidziridzwa Midziyo" maLED, ayo ari akanyanya kugovana maLED mumusika. Iyo LED chip inogara nekusanganiswa kune yakadhindwa redunhu bhodhi (PCB), uye inonyanya kufarirwa nekuda kwekuita kwayo kwakawanda. iye PCB yakavakirwa pane chakakona-chakaumbwa, chakatsetseka chinhu, zvinova izvo zvatinowanzoona seSMD. Kana iwe ukatarisa muSMD LED padhuze, unogona kuona diki poindi poindi pakati chaipo peSMD; ndiyo chip ye LED. Unogona kuiwana mune mwenje mabumba uye mafirita mwenje uye kunyangwe mune yekuzivisa mwenje pane yako mbozhanhare.

Imwe yazvino kuitika mune LED indasitiri ndeye COB kana "Chip paBhodi" tekinoroji inova nhanho kumberi yekushandisa simba zvine simba. Zvakafanana neSMD, COB machipisi zvakare ane akawanda diode pane imwechete nzvimbo. Asi mutsauko pakati pechiedza cheLED COB uye SMD ndechekuti ma COB ma LED ane mamwe ma diode.

Zvakanakira SMD LED

1) Iyo SMD inochinja-chinja, uye kuratidzwa kwemachipisi ayo kunotemwa zvinoenderana neakadhindwa wedunhu dhizaini, uye inogona kuchinjwa kusangana akasiyana einjiniya mhinduro.

2) SMD mwenje sosi ine hombe yekuvhenekesa kona inosvika ku120 & Phi; 160 degrees, diki saizi uye huremu huremu hwezvigadzirwa zvemagetsi, kuwanda kwegungano uye saizi uye huremu hwezvinhu zvekuvhara zvinongori zve1 / 10 zveizvo zvakajairika plug-in zvinhu.

3) Ine yakakwirira kuvimbika uye yakasimba anti-vibration kugona.

4) Low solder kwemajoini kuremara mwero uye kugadzirisa kugadzirwa kushanda.
