ʻO SMD ka pōkole no Surface Mounted Device, kahi e hoʻopili ai i nā mea e like me nā kīʻaha kukui, brackets, chips, leads, a me ka epoxy resin i loko o nā kikoʻī like ʻole o nā pahu kukui, a laila hana i nā modula hōʻike LED ma ke kūʻai ʻana iā lākou ma kahi papa PCB ma ke ʻano o nā pā.

Pono nā hōʻike SMD e hōʻike ʻia nā pahu LED, ʻaʻole maʻalahi wale ke kumu o ke kamaʻilio ʻana ma waena o nā pika, akā e hopena pū kekahi i ka hana pale maikaʻi ʻole, e pili ana i ka hana kiʻi a me ke ola lawelawe.

Hoʻolālā kiʻi o SMD microstructure

ʻO COB, i hoʻopau ʻia ʻo Chip On Board, e pili ana i ka ʻenehana hōkeo LED e hoʻopaʻa pololei i nā pahu kukui LED ma luna o nā papa kaapuni paʻi (PCB), ma mua o ke kūʻai ʻana i nā pūʻolo LED hoʻokahi i nā PCB.

Loaʻa i kēia ʻano hoʻopihapiha kekahi mau pono i ka hana ʻana a me ka hana pono ʻana, ka maikaʻi o ke kiʻi, ka pale, a me nā noi micro spacing liʻiliʻi.
