ʻO Waht ka SMD LED BT Substrate:

Pili ka SMD LED BT Substrate i ka PCB i hana ʻia me nā Pono BT a noi ʻia i nā huahana SMD LED. ʻOkoʻa mai ka PCB maʻamau , hoʻopili ʻia nā mea BT i MD LED BT Substrate, kahi huahana nui na Mistubishi Gas Chemical Co., Inc. ʻO nā mea hana BT i hana ʻia ʻo B (Bismaleimide) a me T (Triazine) resin i loaʻa nā pōmaikaʻi o ke kiʻekiʻe TG (255 ~ 330 ° C), ke kūpale ʻana i ka wela (160 ~ 230 ° C), ke kūpikū o ke kūpikipiki, ka hoʻomau dielectric haʻahaʻa (DK) a me ka hoʻoliʻiliʻi haʻahaʻa kumu (Df). ʻO SMD LED kahi pae hou e kau ana i ka semiconductor light-emitting device, me kahi huina liʻiliʻi e lūlū ana, nui ka mālamalama, hilinaʻi nui, nā kala kukui me nā kala keʻokeʻo, hoʻohana nui ʻia ia i nā ʻano uila. ʻO ka papa PCB kekahi o nā mea hana SMD LED nui.

Ka waena o SMD a me COB LED

Kuhi ʻo SMD i ka huaʻōlelo "LED Mounted Device" LEDs, ʻo ia nā LED i kaʻana like ʻia i ka mākeke. Hoʻohui mau ʻia ka ipukukui LED i kahi papa kaapuni i paʻi ʻia (PCB), a he mea makemake nui ʻia ia no ka maʻalahi o ka maʻalahi. kūkulu ʻia ʻo PCB ma luna o ka huinahā, ʻano pālahalaha, ʻo ia ka mea a mākou e ʻike maʻamau ma ke ʻano he SMD. Inā ʻoe e nānā pono iā SMD LED, hiki iā ʻoe ke ʻike i kahi kiko ʻeleʻele liʻiliʻi ma waena pono o ka SMD; ʻo ia ka ʻāpana LED. Hiki iā ʻoe ke loaʻa iā ia i nā ipukukui kukui a me nā kukui a me nā kukui a me ke kukui hoʻolaha ma kāu kelepona paʻalima.

ʻO kekahi o nā hanana hou loa i ka ʻoihana LED ʻo COB a i ʻole ʻenehana "Chip on Board" kahi ʻanuʻu i mua no ka hoʻohana ikehu ʻoi aku ka maikaʻi. ʻIke like me SMD, loaʻa i nā ʻāpana COB nā diode he nui ma ka ʻaoʻao like. Akā ʻo ka ʻokoʻa ma waena o ke kukui COB a me SMD, ʻoi aku ka nui o nā diode COB.

Nā pōmaikaʻi o SMD LED

1) ʻOi aku ka maʻalahi o ka SMD, a hoʻoholo ʻia ka hōʻike o kāna ʻāpana e like me ka hoʻonohonoho ʻana o ka papa kaapuni, a hiki ke hoʻololi ʻia e kū i nā ʻenekini ʻokoʻa.

2) Loaʻa i kahi kumu kukui SMD kahi kihi hoʻomālamalama nui aʻe o 120 & Phi; 160 kekelē, ka liʻiliʻi a me ka māmā o nā huahana uila, ka hoʻohuihui kiʻekiʻe a me ka nui a me ke kaumaha o nā ʻāpana uhi e pili wale ana i 1/10 o nā mea plug-in maʻamau.

3) He kūlana kiʻekiʻe kona a me ka hiki i ka anti-vibration ikaika.

4) Hōʻemi haʻahaʻa solder hui kīnā a hoʻomaikaʻi i ka hana ʻana i ka pono.
