Sida muraayadda fiber galaaska, substrate aluminium waa xamuul caadi ah oo PCB ah. Farqiga u dhexeeya waa in conductivity ah kaamerada of substrate aluminium waa ka sii badan in ka mid ah guddiga fiber galaas, sidaa daraadeed waxa uu guud ahaan waxaa loo isticmaalaa in qaybaha awooda iyo jeer kale oo u nugul kulaylka, sida nalalka LED, badalato iyo xoogga drives.Here, ee  aluminium pcb keentay kuu sheegaya waxa ku kala duwan substrate-ka aluminium iyo fiberglass-ka.

Farqiga u dhexeeya substrate aluminium iyo fiberglass

Aluminium iyo Fiberglass Fibreglass waa midka ugu badan ee la isticmaalo ee looxyada wareega, sida xaashiyaha inta badan la isticmaalo ee loo yaqaan 'FR4 sheet'. Waxay ku saleysan tahay fiber galaaska oo ah substrate, ka dib marka dusha sare ee maarta ay ku xiran tahay sameynta saxan naxaas ah oo xiran, taxane ka dib dib-u-soo-celinta si loo sameeyo guddiga wareegga daabacan.

Foornada naxaasta ah ee looxa muraayadda muraayadda ah waxaa lagu dhejiyaa looxa muraayadda muraayadda iyada oo loo marayo galka, taas oo guud ahaan ah nooca laydhka. Guddiga muraayadda laftiisa laftiisu waa dahaaran yihiin oo waxay leeyihiin astaamo holac leh, laakiin kuleylka kuleylka ayaa aad u liita. Dhibaatada kuleylka kuleylka ee muraayadda fiber galaaska, qayb ka mid ah qaybaha leh shuruudaha kala-baxa kuleylka guud ahaan waxay qaataan habka loo maro kuleylka iyada oo loo marayo godadka.ka dibna loo maro kuleylka kuleylka kuleylka kuleylka.

Laakiin loogu talagalay LED, maahan xiriir toos ah oo lala yeesho kuleylka kuleylka. Haddii daloolka loo isticmaalo kuleylka kuleylka, saameyntu way ka fog tahay, sidaas darteed LED guud ahaan waxay u isticmaashaa substrate aluminium sida qalabka guddiga wareegga.

Qaab dhismeedka aluminiumku wuxuu asal ahaan la mid yahay kan saxanka maroogga, marka laga reebo in fiber galaaska lagu beddelo aluminium. Sababtoo ah aluminiumka laftiisa ayaa ah mid tabinta, haddii aluminiumku si toos ah u dahaadho naxaas, wuxuu sababi doonaa wareeg gaaban. dhejiska ku jira substrate-ka aluminium marka lagu daro inuu yahay shay isku xidha, laakiin sidoo kale sida qalabka dahaarka u dhexeeya naxaasta iyo saxanka aluminium. Dhumucda giraanta ayaa saamayn gaar ah ku yeelan doonta dahaadhka saxanka, dahaadhka aadka u khafiifka ahi ma fiicna, sidoo kale qaro weyn ayaa saameyn doonta kuleylka kuleylka.

Haddii substrate-ka aluminium ee nalka LED-ka uu yahay mid tabin leh

Sida laga arki karo qaab dhismeedka aluminium-ka kor ku xusan, in kasta oo walxaha aluminiumku yahay tabeelle, dahaadhka u dhexeeya dahaarka naxaasta iyo walxaha aluminium waxaa lagu fuliyaa cusbooneysi. iyo aluminiumka gadaashiisa waxaa loo isticmaalaa sida qalabka kuleylka kuleylka, sidaas darteed looma gudbin foornada naxaasta ee hore.

Aluminium ayaa ka dahaaran biraha naxaasta ah xarkaha, laakiin wuxuu leeyahay kala duwanaansho koronto. Marka lagu daro aluminiumka aluminium, waxaa jira kala-bax kaamera sare oo ka sameysan maadada naxaasta ah, saxankan guud ahaan waxaa loo isticmaalaa qaybaha korantada korontada, qiimahiisa waa aad uga sarreysa substrate-ka aluminium.

Waxyaabaha kor ku xusan waxaa abaabulay oo daabacay alaab-qeybiyeyaasha pcb substrate LED. Haddii aadan fahmin, fadlan nagala tasho " ymspcb.com ".
