Hauv daim ntawv no, Yongmingsheng, cov chaw tsim tshuaj paus ntawm txhuas txheej substrate PCB , yuav qhia cov ntawv txhuas txhuas PCB. Peb txhua tus paub tias txhuas yog ib hom hlau nrog hluav taws xob nrog kev sib raug zoo. Yuav ua li cas nws siv tau los ua cov khoom siv PCB?

Qhov no yog vim hais tias txhuas txheej txheej txheej muaj peb txheej txheej ntawm cov qauv, uas yog: tooj liab ntawv ci, txheej insulating thiab hlau txhuas.Vim tias muaj txheej insulating, cov hlau txheej yuav siv lwm yam khoom siv dua li txhuas? Xws li tooj liab phaj, stainless hlau, hlau phaj, silicon steel phaj, thiab lwm yam .Qhov khoom siv dab tsi yog siv rau cov hlau txheej, ntxiv rau kev txiav txim siab txog qhov cua sov ua kom zoo, tab sis kuj xav txog lub thermal expansion coefficient ntawm cov hlau substrate, muaj peev xwm ua kom sov, muaj zog, tawv, lub cev, qhov chaw hauv lub xeev thiab tus nqi thiab lwm yam mob.

txhuas tub ntxhais pcb

Dab tsi yog qhov zoo ntawm cov txhuas hauv av?

Zoo tshav kub dissipation kev ua tau zoo

Ua tau raws RoHS ib puag ncig kev xav tau

Ntau tsim rau SMT cov txheej txheem

Siab dua nqa tam sim no

Hauv cov qauv tsim hluav taws xob, cov qauv hluav taws xob tso tawm kom ua tau zoo, yog li txo qhov module ua haujlwm kub, ua kom ntev lub neej kev pab, txhim kho lub zog ceev thiab kev ntseeg tau;

Txo txo ​​lub rooj sib txoos ntawm lub tshuab hluav taws xob thiab lwm yam khoom siv (nrog rau cov khoom siv hluav taws xob ua kom zoo), txo cov khoom ntim, txo cov nqi kho vajtse thiab sib dhos;

Hloov cov pob zeb me me uas tsis tuaj yeem ua kom zoo nkauj rau kev siv dag zog zoo dua.

Kev faib tawm ntawm cov txhuas substrates

Aluminium raws tooj liab clad panels tau muab faib ua peb pawg:

General-lub hom phiaj aluminium puag tooj liab clad phaj, insulating txheej los ntawm epoxy iav daim ntaub tsevneeg ntawv;

Aluminium puag tooj liab clad phaj nrog kub kub dissipation, rwb thaiv tsev txheej yog li ntawm siab thermal conductivity epoxy cob lossis lwm cov resins;

Aluminium puag tooj liab cias clad phaj rau ntau zaus ntawm Circuit Court, insulating txheej los ntawm polyolefin resin los yog polyimide resin iav daim ntaub sib khi daim ntawv.

Lub ntsiab tseem ceeb

Cov khoom teeb, muaj hwj chim siab LED teeb khoom.

Cov cuab yeej kaw suab, khoom siv ua ntej, tshuab ua kom muaj zog, thiab lwm yam.

Cov khoom siv fais fab, DC / AC hloov, tus txuas txuas txuas, txuas lub xeev tso tawm, thiab lwm yam.

Cov khoom sib txuas lus, tso zis tawm ntau zaus, cov cuab yeej lim dej, lub tshuab hluav taws xob xa mus.

Qhov saum toj no yog kev teeb tsa thiab luam tawm los ntawm PCB cov neeg xa khoom ntawm cov txhuas txheej. Yog tias koj tsis nkag siab, txais tos sab laj rau peb ntawm " ymspcb.com "
