Luv qhia txog cov teeb meem ntawm CCL LED
May 28, 2018

Ua ke nrog cov khoom siv hluav taws xob rau lub teeb, thin, me me, qhov siab, ntau qhov kev ua hauj lwm, luam tawm kev sib koom tes thiab muaj kev sib koom ua ke, kev siv hluav taws xob ntau dua thiab ntau dua, lub PCB substrate heat dissipation yuav tsum ua ntau dua ceev nrooj, radiating substrate tsis zoo, yuav ua rau cov khoom ntiag tug daim npav luam tawm khoom ua rau overheating, yog li ntawd qhov kev ntseeg ntawm poob. Nyob rau hauv qhov ntsiab lus lub hnub yug high heat dissipation hlau PCB substrate.

 

Aluminium base tooj liab clad laminate yog qhov feem ntau siv PCB hlau substrate, qhov khoom yog nyob rau hauv 1969 los ntawm cov Japanese Sanyo lub teb chaws tsim, xyoo 1974 pib siv nyob rau hauv cov qauv STK series zog amplifier hybrid integrated circuit. Thaum pib ntawm 80's hlau theem tooj liab-clad phaj hauvChinais tsuas yog siv rau hauv cov tub rog cov khoom, PCB hlau substrate cov khoom yog kiag li ntawm imports, tus nqi kim. Nyob rau hauv lub lig 80's, nrog rau kev nthuav dav ntawm aluminium puag tooj tooj liab clad laminate nyob rau hauv lub tsheb, maus taus hluav taws xob khoom nyob rau hauv ib tug ntau ntawm kev siv thiab tshuaj, los txhawb txoj kev loj hlob ntawm Tuam Tshoj lub hlau substrates rau PCB tshawb thiab tsim technology thiab nws cov ntaub ntawv uas nws kim heev hluav taws xob, kev sib txuas lus, hluav taws xob thiab lwm yam hauj lwm.

Cov neeg sawv cev rau lub teb chaws hlau substrate cov tub lag luam Japan, Japanese Electric Sumitomo Panasonic, DENKA HITY PLATE, USA Beggs tuam txhab. Nyiv Sumitomo hlau PCB substrate muaj peb series (xws li txhuas lub hauv paus tooj lauj kaub laminate, tooj liab clad hlau hlau, tooj liab clad laminate). Aluminium puag tooj tooj liab laminate, tooj liab clad steel hlau, tooj liab clad laminate cov khoom muag tau ALC-1401 thiab ALC-1370, ALC-5950 thiab ALC-3370 thiab ALC-2420. Ib qho ntawm cov khoom lag luam uas tau tsim tau tsim muaj hlau ua qauv tooj liab-clad laminate ntau lawm yog lub xeev 704th Hoobkas, lub lig 90's muaj ntau ntau yam tseem muaj kev tsim kho thiab kev tsim cov khoom txhuas tooj hlau tooj sib txig laminate. Cov hlau substrate 704 tseem muaj peb hom, namely aluminium puag copper clad laminate, tooj liab clad laminate, hlau puag tooj liab clad laminate. Aluminium puag tooj tooj liab lub lad xwm Hoobkas 704 raws li nws tus cwj pwm txawv yog faib ua ntau hom thiab siab kub dissipation thiab siab zaus Circuit Court siv peb cov qauv. Raws li kwv yees, lub ntiaj teb cov hlau raws li PCB tus nqi ntawm kwv yees li $ 2000000000 hauv 1991, cov Japanese hlau raws li PCB tus nqi rau 2500000000 Yen, nyob rau hauv 1996 rau 6000000000 yen hauv 20
