Faa’iidooyinka substrate aluminium PCB

a. Kala-baxa kulaylka ayaa si weyn uga wanaagsan qaabka caadiga ah ee FR-4.

b. Dielectric-ka la isticmaalo ayaa inta badan 5 ilaa 10 jeer ka ah kulaylka kuleyliyaha galaas dhaqameedka epoxy-ga iyo 1/10 dhumucda.

c. Tusmada wareejinta kulaylku way ka waxtar badan tahay PCB-ga adag ee dhaqameed.

d. Waxaad isticmaali kartaa miisaanyo naxaas ah oo ka hooseeya kuwa lagu muujiyay shaxda IPC ee lagula taliyay.

Aluminium PCB

Codsiga aluminium substrate PCB

1. Qalabka maqalka ah: cod-weyneyaasha soo-gelinta iyo soo-saarka, cod-weyneyaal dheellitiran, cod-weyneeyeyaal, hor-u-qaadayaal, cod-weynayaal, iwm.

2. Qalabka korantada: maamulaha beddelka, beddelka DC/AC, SW regulator, iwm.

3. Qalabka elektaroonigga ah ee isgaarsiinta: cod-weyneeye-sare wareegga warbixinta.

4. Qalabka iswada ee xafiiska: matoorada, iwm.

5. Baabuurka: nidaamiyaha elektarooniga ah, dab-damiya, kontaroolka, iwm.

6. Kumbuyuutar: guddida CPU ‘floppy disk drive’ unugga korantada, iwm.

7. Module korantada: inverter “Relay state adag” buundada hagaajinta, iwm.

Aluminium substrates ayaa si weyn loo isticmaalaa. Qalabka guud ee maqalka, qalabka korontada, iyo qalabka elektaroonigga ah ee isgaarsiinta, waxaa jira aluminium substrate PCBs, qalab xafiiseed, baabuur, kombiyuutaro iyo qaybo koronto.

Waxaa jira saddex farqi oo u dhexeeya guddiga fiberglass-ka iyo aluminium substrate PCB

A. Qiimaha

Qaybaha muhiimka ah ee tube fluorescent LED waa: looxa wareegga, chip LED iyo sahayda korantada. Looxyada wareegga caadiga ah waxay u qaybsan yihiin laba nooc: aluminium substrates iyo looxyada fiberglass. Marka la barbardhigo qiimaha guddiga fiberglass-ka iyo substrate aluminium, qiimaha guddiga fiberglass wuxuu noqon doonaa mid aad u jaban, laakiin waxqabadka substrate aluminium ayaa ka fiicnaan doona kan looxa fiberglass.

B. Dhinacyada farsamada

Sida laga soo xigtay qalabyada kala duwan iyo hababka wax soo saarka, looxyada fiberglass waxaa loo qaybin karaa saddex nooc: looxyada fiberglass-ka naxaasta ah ee laba-geesoodka ah, looxyada fiberglass-ka ee daloolsan, iyo looxyada fiberglass-ka naxaasta ah ee hal dhinac ah. Dabcan, qiimaha looxyada fiberglass-ka ee laga sameeyay alaab kala duwan ayaa noqon doona mid kala duwan. Qiimaha muraayadaha fiberglass-ka ee laga sameeyay agabyo iyo teknooloji kala duwan sidoo kale way kala duwan yihiin. Saamaynta kulaylka ee tuubada fluorescent LED iyo guddiga fiber galaas uma fiicna sida tuubada fluorescent LED ee ka kooban substrate aluminium.

C. Waxqabad

Sida aynu wada ognahay, substrate-ka aluminiumku wuxuu leeyahay waxqabadka kulaylka wanaagsan, iyo waxqabadkeeda kuleylka kuleylka ayaa aad uga fiican guddiga fiberglass-ka. Sababtoo ah substrate-ka aluminiumku wuxuu leeyahay kulaylka kulaylka wanaagsan, substrate aluminiumku wuxuu door muhiim ah ka ciyaaraa nalalka LED-ka.
