ʻO ka Papa SinkPAD (SinkPAD PCB) kahi ʻano kūikawā o ka PCB metala, ʻo ka PAD conductive thermal kahi convexity wahi o ke kumu keleawe / pedestal, i hiki ai i ka PAD thermal o LED ke hoʻopā i ka convexity wahi o ke kumu metala, a laila ka wela. E hoʻopau ʻia ʻo LED i ka lewa me ka wikiwiki a ʻoi aku ka maikaʻi ma mua o ka MCPCB maʻamau, i hiki iā ʻoe ke kiʻi i ka hana wela maikaʻi loa no nā LED mana kiʻekiʻe, a i ʻole no nā ʻāpana ʻē aʻe.


ʻO ke keleawe ka mea kaulana loa i hoʻohana ʻia no SinkPAD metal core, ʻoiai ʻo ka conductivity thermal he 400W/m.K, no laila ua kapa ʻia ka poʻe ma ke ʻano he "SinkPAD copper core board", a i ʻole "SinkPAD copper core PCB". ʻOiai ʻo 1-5W/m.K wale nō ka conductivity thermal o ka Metal Core PCB, no ka mea, ua kaupalena ʻia ka waiwai i ka papa dielectronic ma waena o ke keleawe a me ke kumu metala.


Hāʻawi ka SinkPad i ka hoʻoili wela maikaʻi loa mai ke LED a i ka pā kumu metala/pedestal, ʻoiai e mālama ana i ka hoʻokaʻawale uila maikaʻi loa. Hāʻawi ke kumu keleawe i ka pono mechanical substrate o ka papa, a hāʻawi a hoʻoili i ka wela i kahi wela wela, e kau ana i luna a i ʻole pololei i ka ea ambient.


No ka mea, aia ka papa uila uila i loko o kahi pahu keleawe o ke kumu keleawe, no laila ua kapa mākou i kēlā ʻano papa ʻo "SinkPAD Board (SinkPAD PCB)", a no ka mea ma ka hapa nui o nā hihia, he keleawe ka mea o ke kumu, no laila ua kapa ʻia ʻo ia ʻo " SinkPAD copper core PCB", a i ʻole "SinkPAD copper board".
