Circuit Board Thermal Conductivity thiab Heat Dissipation Design Processability Requirements

1. Thaum tshav kub kub dab dej duab, thickness thiab cheeb tsam ntawm tus tsim

Raws li cov txheej txheem thermal tsim ntawm cov khoom siv hluav taws xob yuav tsum tau ua tiav, yuav tsum xyuas kom meej tias qhov sib txuas ntawm cov khoom siv hluav taws xob tsim hluav taws xob, qhov kub thiab txias ntawm PCB kom ua tau raws li cov khoom tsim.

2. Kub dab dej mounting nto roughness tsim

Rau kev tswj xyuas thermal ntawm cov khoom siv hluav taws xob siab, lub dab dej kub thiab cov khoom siv ntawm qhov mounting nto roughness yuav tsum tau lav kom ncav cuag 3.2µm lossis txawm 1.6µm, tau nce qhov chaw sib cuag ntawm cov hlau nto, ua kom tag nrho cov thermal conductivity. ntawm cov yam ntxwv ntawm cov khoom siv hlau, kom txo tau qhov kev sib cuag thermal.Tab sis feem ntau, qhov roughness yuav tsum tsis txhob siab dhau.

3. Sau cov khoom xaiv

Txhawm rau txo cov thermal tsis kam ntawm qhov sib cuag ntawm lub siab-lub zog tivthaiv mounting nto thiab lub dab dej kub, cov ntaub ntawv rwb thaiv tsev thiab thermal conductivity, thermal conductivity muab tub lim cov ntaub ntawv uas muaj thermal conductivity yuav tsum tau xaiv, piv txwv li, rwb thaiv tsev thiab thermal conductivity. cov ntaub ntawv xws li beryllium oxide (los yog txhuas trioxide) ceramic ntawv, polyimide zaj duab xis, mica ntawv, muab cov ntaub ntawv xws li thermally conductive silicone roj, ib tug-tivthaiv vulcanized silicone roj hmab, ob-tivthaiv thermally conductive silicone roj hmab, thermally conductive silicone roj hmab ncoo.

4. Installation tiv tauj nto

Kev txhim kho yam tsis muaj kev rwb thaiv tsev: tivthaiv mounting nto → tshav kub dab dej mounting nto → PCB, ob-txheej sib cuag nto.
Insulated installation: tivthaiv mounting nto → tshav kub dab dej mounting nto → rwb thaiv tsev txheej → PCB (los yog chassis plhaub), peb txheej ntawm kev sib cuag nto.Rwb thaiv tsev txheej ntsia nyob rau hauv uas theem, yuav tsum tau raws li cov khoom mounting nto los yog PCB nto hluav taws xob rwb thaiv tsev yuav tsum tau.

kev kub ceev xaiv thiab qhov chaw tshuab
