Qhov zoo ntawm aluminium substrate PCB

a. Lub tshav kub dissipation yog qhov zoo dua li tus qauv FR-4 qauv.

b. Cov dielectric siv feem ntau yog 5 mus rau 10 npaug ntawm thermal conductivity ntawm cov iav epoxy thiab 1/10 lub thickness.

c. Qhov ntsuas kub hloov pauv tau zoo dua li cov txheej txheem nruj PCB.

d. Koj tuaj yeem siv qhov hnyav tooj liab qis dua cov uas pom hauv IPC daim ntawv pom zoo.

Aluminium PCB

Daim ntawv thov ntawm aluminium substrate PCB

1. Cov khoom siv suab: input thiab output amplifiers, balanced amplifiers, audio amplifiers, preamplifiers, power amplifiers, etc.

2. Cov khoom siv fais fab: hloov regulator, DC / AC converter, SW regulator, thiab lwm yam.

3. Cov khoom siv hluav taws xob sib txuas lus: lub suab nrov nrov qhia Circuit Court.

4. Cov khoom siv hauv chaw ua haujlwm automation: lub cev muaj zog tsav, thiab lwm yam.

5. Tsheb: hluav taws xob regulator, igniter, fais fab tswj, thiab lwm yam.

6. Khoos phib tawj: CPU board ‘floppy disk drive’ fais fab mov chav tsev, thiab lwm yam.

7. Fais fab module: inverter “khoom lub xeev relay” rectifier choj, thiab lwm yam.

Aluminium substrate yog dav siv. Hauv cov khoom siv suab, cov cuab yeej siv hluav taws xob, thiab cov khoom siv hluav taws xob sib txuas lus, muaj cov khoom siv hluav taws xob txhuas, cov khoom siv hluav taws xob hauv chaw ua haujlwm, tsheb, khoos phis tawj thiab cov khoom siv hluav taws xob.

Muaj peb qhov sib txawv ntawm fiberglass board thiab aluminium substrate PCB

A. Nqe

Cov khoom tseem ceeb ntawm LED fluorescent raj yog: Circuit Court board, LED nti thiab tsav tsheb fais fab mov. Cov kab hluav taws xob sib txuas tau muab faib ua ob hom: aluminium substrates thiab fiberglass boards. Sib piv cov nqi ntawm fiberglass board thiab aluminium substrate, tus nqi ntawm fiberglass board yuav pheej yig dua, tab sis kev ua tau zoo ntawm aluminium substrate yuav zoo dua li ntawm fiberglass board.

B. Technical yam

Raws li cov khoom sib txawv thiab cov txheej txheem tsim khoom, fiberglass boards tuaj yeem muab faib ua peb hom: ob-sided tooj liab ntawv ci fiberglass boards, perforated tooj liab foil fiberglass boards, thiab ib leeg-sab tooj liab ntawv fiberglass boards. Tau kawg, tus nqi ntawm fiberglass boards ua los ntawm cov khoom sib txawv yuav txawv. Tus nqi ntawm fiberglass panels ua los ntawm cov khoom sib txawv thiab cov thev naus laus zis kuj txawv. Lub tshav kub dissipation nyhuv ntawm LED fluorescent raj thiab iav fiber board tsis zoo li cov LED fluorescent raj uas muaj txhuas substrate.

C. Kev ua tau zoo

Raws li peb txhua tus paub, aluminium substrate muaj qhov ua tau zoo thaum tshav kub kub dissipation, thiab nws cov cua kub dissipation kev ua tau zoo dua li fiberglass board. Vim tias aluminium substrate muaj thermal conductivity zoo, aluminium substrate plays lub luag haujlwm tseem ceeb hauv thaj chaw ntawm LED teeb.
