Cov ntsiab lus zoo ntawm cov tuab - hom tsav tsheb rau LED T8 teeb raj

Cov tuab - hom tsav tshebboard siv PCB substrate ntawm 1.6 hli los yog tuab, ua kom muaj txiaj ntsig zoo ntawm kev tswj xyuas thermal los ntawm cov khoom siv engineering. Kev nce ntawm 20% mus rau 50% nyob rau hauv lub substrate thickness ua rau nce ntau tshaj 30% thermal muaj peev xwm, ua ke nrog ib tug thermal conductivity ntawm 1.5W / mK, tsim ib tug multi-dimensional tshav kub dissipation txoj kev, zoo tshem tawm hauv zos hotspots. Qhov kev tsim no ruaj khov rau kev ua haujlwm kub ntawm cov khoom siv hluav taws xob (xws li MOSFETs, rectifiers, thiab tswj ICs) ntawm qis dua tus nqi tseem ceeb ntawm 70 degree, kom ntseeg tau tias lub neej ntev ntawm 105℃ntsuas electrolytic capacitors ncav cuag 50,000 teev, ua tau raws li cov kev cai nruj ntawm LM-80.

Lub thickened substrate txheej muab qhov chaw txaus rau kev koom ua ke ntawm siab - specifications. Qhov kev tsim no tau sib xws nrog kev lag luam - qib 105℃electrolytic capacitors, nrog rau lawv qhov kev sib txawv ntawm kev tswj nruj nruj hauv ± 10%; nws txhawb nqa daim ntawv thov ntawm TO-220 ntim MOSFETs, txo cov conduction kuj los ntawm 40%; ua ke nrog 2oz copper foil thickness thiab ib txoj kab dav ntawm ntau tshaj 2 hli, nws txo qis impedance poob. Los ntawm kev sim tiag tiag, qhov kev teeb tsa no tau ua rau kev tsav tsheb kom ua tiav qhov nruab nrab lub sijhawm poob qis dua 80,000 teev, thiab kev tiv thaiv kev tiv thaiv tau mus txog 6kV tiv thaiv qib uas xav tau los ntawm IEC 61000-4-5 Qib 4 tus qauv.

Lub tuab substrate tsim raws li cov neeg kho tshuab kev ruaj ntseg yuav tsum nyob rau hauv hnyav ib puag ncig. Nws lub zog dabtsi yog khoov tshaj 400 MPa, ua tau raws li IPC-6012 Class 3 cov qauv kev lag luam; nws ua tiav qhov kev xeem IEC 60068-2-6 kev co (10-500Hz / 1.5mm amplitude rau 72 teev) thiab ISTA-3A tus qauv 100G / 6ms cuam tshuam kev xeem. Kev txheeb xyuas engineering qhia tias cov qauv no txo qis qhov ua tsis tiav ntawm cov pob qij txha nyob rau hauv qhov kub thiab txias ntawm -30℃rau +70℃los ntawm 75%.

Lub rwb thaiv tsev interlayer thickness tshaj 0.4 hli muab lub zog dielectric ntawm tshaj 3kV, ua tau raws li UL 8750 tus qauv kev nyab xeeb. Los ntawm kev ua kom zoo ntawm cov qauv tsim ntawm cov khoom siv, cov hluav taws xob cuam tshuam hluav taws xob raug txo los ntawm 15dBμV / m, thiab kev cuam tshuam ua haujlwm tau ruaj khov nyob rau hauv 30dBμV txwv tau teev tseg hauv EN 55015 Class B. Cov kev daws teeb meem no ib txhij ua raws li qhov yuav tsum tau muaj ntawv pov thawj ntawm cov kev lag luam loj hauv ntiaj teb no MC1 thiab FCC.
