1. He aha ka COB soft package
E ʻike paha ka poʻe netizen makaʻala he mea ʻeleʻele ma kekahi mau papa kaapuni, no laila he aha kēia mea?No ke aha ia ma ka papa kaapuni?He aha ka hopena?ʻOiaʻiʻo, he ʻano pūʻolo kēia.Kāhea pinepine mākou iā ia he "pack soft".Ua ʻōlelo ʻia he "paʻakikī" maoli ka pūʻolo palupalu, a ʻo kāna mea i hana ʻia he epoxy resin., ʻIke mākou i ka loaʻa ʻana o ka ʻili o ke poʻo hoʻokipa no kēia mea, a aia ka chip IC i loko.Kapa ʻia kēia kaʻina hana "ka hoʻopaʻa ʻana", a kapa mākou iā ia he "paʻa".
He kaʻina hana hoʻopaʻa uea kēia i ke kaʻina hana chip.ʻO kona inoa Pelekania ʻo COB (Chip On Board), ʻo ia hoʻi, chip ma luna o ka pahu pahu.ʻO kēia kekahi o nā ʻenehana hoʻokomo puʻupuʻu.Hoʻopili ʻia ka chip me ka resin epoxy.Kau ʻia ma ka PCB i paʻi ʻia ka papa kaapuni, no ke aha i loaʻa ʻole ai kēia ʻano pūʻolo i kekahi mau papa kaapuni, a he aha nā ʻano o kēia ʻano pūʻolo?
2. Nā hiʻohiʻona o ka pūʻolo palupalu COB
ʻO kēia ʻano ʻenehana paʻa paʻakikī no ka uku pinepine.E like me ka mea maʻalahi loa e kau ana i ka puʻupuʻu, i mea e pale ai i ka IC kūloko mai ka pōʻino, pono maʻamau kēia ʻano paʻi i ka hoʻoheheʻe ʻana i hoʻokahi manawa, i kau ʻia ma ka ʻili keleawe keleawe o ka papa kaapuni.He poepoe a he eleele ke kala.Loaʻa i kēia ʻenehana hoʻopihapiha nā mea maikaʻi o ke kumu kūʻai haʻahaʻa, mālama wahi, māmā a lahilahi, hopena wela wela maikaʻi, a me ke ʻano hoʻopili maʻalahi.Nui nā kaapuni hoʻohui, ʻoi aku ka nui o nā kaapuni haʻahaʻa haʻahaʻa, pono e hoʻohui ʻia i kēia ʻano.Alakaʻi ʻia ka chip kaapuni me nā uea metala hou aʻe, a laila hāʻawi ʻia i ka mea hana e kau i ka chip ma ka papa kaapuni, e kūʻai aku me ka mīkini, a laila e hoʻopili i ke kāpili e paʻa a paʻakikī.
3. Nā manawa noi
No ka loaʻa ʻana o kēia ʻano pūʻolo i kāna mau hiʻohiʻona ponoʻī, hoʻohana ʻia ia i kekahi mau kaʻa kaapuni uila, e like me nā mea pāʻani MP3, nā mea uila, nā kiʻi kamepiula, nā consoles pāʻani, a me nā mea ʻē aʻe, i ka ʻimi ʻana i nā kaapuni haʻahaʻa.
ʻO ka ʻoiaʻiʻo, ʻaʻole i kaupalena ʻia ka ʻeke palupalu COB i nā chips, ua hoʻohana nui ʻia ia i nā LED, e like me ke kumu kukui COB, kahi ʻenehana kumu kukui i hoʻohui ʻia i hoʻopili pololei ʻia i ke aniani metala substrate ma ka chip LED.
