Ntchito ya MCPCB Imawonjezera Kuchita ndi Kudalirika kwa UV LED

M'munda wa ma LED a UV, kugwiritsa ntchito Metal Core Printed Circuit Board (MCPCB) kumagwira ntchito yofunika kwambiri pakuwongolera magwiridwe antchito, kasamalidwe kamafuta komanso kudalirika kwazinthu zonse.

Kuwotcha Moyenera

MCPCB ndiyabwino kwambiri pakuchotsa kutentha, kuwonetsetsa kuti magwiridwe antchito ndi moyo wautali wa nyali za UV LED. Zida zachitsulo za MCPCB nthawi zambiri zimapangidwa ndi aluminiyamu kapena mkuwa wokhala ndi matenthedwe apamwamba kwambiri. Kutentha kwapadera kumeneku kumapangitsa kuti kutentha kwapangidwe kuthe msanga, kuteteza kutentha ndikuwonetsetsa kuti zipangizo zimagwira ntchito mkati mwa kutentha koyenera.

Kuwonjezeka kwa Thermal Conductivity

Thermal conductivity ya MCPCB ndi pafupifupi nthawi 10 kuposa FR4PCB. MCPCB imathandizira kukwaniritsa kutentha kofananako ndikuchepetsa chiopsezo cha malo otentha komanso kupsinjika kwamafuta paKuwala kwa UV LED.Chotsatira chake, magetsi amasunga ntchito zawo zabwino kwambiri komanso kudalirika kwakukulu ngakhale kwa nthawi yaitali.

Kudalirika Kwambiri

MCPCB imapereka mphamvu zamakina apamwamba komanso kukhazikika kwamafuta. Mwachitsanzo, coefficient of thermal expansion (CTE) ya MCPCB ikhoza kufananizidwa ndi ma LED a UV, kuchepetsa chiopsezo cha kulephera kwa makina chifukwa cha kusagwirizana kwa kutentha. 

Magetsi Insulation

MCPCB imapereka kutchinjiriza kwamagetsi pakati pa chitsulo pakati ndi zigawo zozungulira kuti zitsimikizire kuti magwiridwe antchito otetezeka komanso odalirika a machitidwe a UV LED. Dielectric wosanjikiza nthawi zambiri amapangidwa ndi zinthu monga epoxy resin kapena thermally conductive fluid (TCF), zomwe zimapereka mphamvu yowononga kwambiri komanso kukana kutchinjiriza. Kutsekemera kwamagetsi kumeneku kumachepetsa chiopsezo cha mafupipafupi kapena phokoso lamagetsi, kuteteza dongosolo kuti lisawonongeke.

Kukhathamiritsa Kwantchito

Pophatikiza MCPCB, opanga amatha kukulitsa magwiridwe antchito awoZida za UV LED. Kutentha kwapang'onopang'ono komanso kutentha kwa MCPCB kumapangitsa kuti UV LED igwire ntchito bwino kwambiri. Kuchita uku kumatsimikizira kutulutsa kwa UV kosasintha, kupangitsa MCPCB kukhala yabwino pazogwiritsa ntchito zosiyanasiyana za UV.
