He aha ka COB LED hōʻike ʻoiaʻiʻo?
Ma muli o ka ʻimi kanaka i ka hōʻike alakaʻi ultra-high definition, ke emi mau nei ka pitch pixel o nā hōʻike LED.
ʻOiai ʻo ka hanauna mua o ka ʻenehana hōʻike, ua oʻo loa ka hōʻike SMD kuʻunamahope o ka umi makahiki ohooulu ana.
No laila, ʻo ke ala ʻenehana e makemake nui ai i ka wā o ka hōʻike alakaʻi micro?
Me ka hoʻomohala ʻana o ka ʻenehana hōʻike LED, puka mai nā ala ʻenehana e like me COB (ʻo ia ka pōkole no Chip On Board).
Eia kekahi, hiki ke hoʻohālikelike ʻia nā ala hoʻopili like ʻole me nā ʻano hana chip like ʻole.
ʻO SMD, e like me ka mea i ʻike ʻia he mau mea i kau ʻia ma luna, e pili ana i ka hoʻohana ʻana i ka ʻenehana mauna i luna e hoʻopaʻa i nā huahana LED.
Hiki iā ia ke hoʻopili i ke kīʻaha kukui, bracket, crystal element, a me nā mea ʻē aʻe i nā kikoʻī like ʻole o nā pahu kukui.
I ka hana ʻana i ka ʻāpana hōʻike me nā ʻokoʻa ʻokoʻa no nā pale hōʻike LED liʻiliʻi, ua hoʻopili ʻia ka pahu kukui i ka papa kaapuni e ka mīkini SMT kiʻekiʻe me ka hoʻoheheʻe hou ʻana i ka wela.
Ke noʻonoʻo nei i ka paʻakikī ʻenehana i ka wā encapsulation, makemake nā mea hana i ka SMD e hana i ka pale hōʻike LED kikohoʻe liʻiliʻi.
ʻO SMD ka ʻenehana mua no nā pale hōʻike micro LED me ka spacing pixel ma lalo o 10mm ma ka mākeke.
Ma ka ʻaoʻao ʻē aʻe, ʻo COB, pōkole no Chip On Board, he ʻenehana hōʻano hou e hoʻopili ana i nā chips LED, ma mua o nā kukui LED, pololei i kahi PCB.
No laila, e hoʻokuʻu ʻia ka COB-LED mai ka nui kino o ka SMD no ka hoʻonā kiʻekiʻe e like me P0.9375.
KikohoʻeLoaʻa nā pale hōʻike micro led i P0.9375mm, P1.25mm, P1.5625 mm a me P1.875 me COB.
Eia kekahi, ʻaʻole hiki ke hōʻole ʻia he ʻoi aku ka maikaʻi o nā waiwai kino o COB.
ʻAʻole ʻoi aku ka māmā o nā modula i hoʻopili ʻia me COB ma mua o ka SMD akā ʻoi aku ka nui o ka ʻike.
Hoʻohālikelike ʻia me SMD, he aha ka COB alakaʻi hōʻike hiki ke lawe mai i ka pōmaikaʻi iā ʻoe e like me lalo:
1; Hoʻopau wela maikaʻi
ʻO kekahi o nā pahuhopu o kēia ʻenehana ʻo ia ka hoʻoponopono ʻana i ka pilikia o ka dissipation wela o SMD a me DIP.
Hāʻawi ka hana maʻalahi iā ia ma mua o nā ʻano ʻelua o ka pāhawewe wela.
2; He kūpono no ka hōʻike LED pitch pitch haiki
No ka pili pono ʻana o nā chips i ka papa PCB, ua haiki ka mamao ma waena o kēlā me kēia ʻāpana i mea e hōʻemi ai i ka pitch pixel e hāʻawi i nā mea kūʻai aku i nā kiʻi ʻoi aku ka maopopo.
3; E hoʻomaʻamaʻa i ka ʻeke
E like me kā mākou i ʻōlelo ai ma luna, ʻoi aku ka maʻalahi o ke ʻano o COB LED ma mua o SMD a me GOB, no laila maʻalahi ke kaʻina hana hoʻopihapiha.
4; ʻOi aku ka wai wai kiʻekiʻe
Me ka puʻupuʻu hou ma luna o ka module glued, hiki iā ia ke pale pono i ka LED ma ka module LED mai ka wai a i ʻole ka haʻahaʻa.
5; ʻOi aku ka maikaʻi o Anti-collision
ʻO ka hoʻolālā modular kūikawā me ka anti-collision gluing hiki ke loaʻa ka hana hōʻike haʻalulu, hāʻawi i ka pale kiʻekiʻe loa no nā LED i nā hopena like ʻole.
6; ʻOi aku i ka pale lepo.
Me ka hana hoʻopaʻa kiʻekiʻe o nā mea hou, ʻo ka COB LED panel panel mai YONWAYTECH LED he lepo ʻole me ka mālamalama maikaʻi loa a hāʻawi i ka hana ʻike maikaʻi loa me ka helu hoʻomaha kiʻekiʻe a me ke kala like.
ʻO ke kumu o ka hilinaʻi kiʻekiʻe e hiki i ka ʻenehana COB ke hoʻopau i ka loulou mana i ke kaʻina hana kukui hoʻokahi.
Eia kekahi, hoʻoneʻe pū ia i ka pahu kukui ma luna o ke kaʻina hana hoʻoheheʻe reflow, i ʻole e hoʻopilikia ka wela kiʻekiʻe ma ke ʻano kuʻuna i ka chip LED a me ka laina kuʻi.
ʻO ka hoʻoheheʻe wela maikaʻi a me ke kūpaʻa oxidation e kōkua pū i ka hilinaʻi kiʻekiʻe.
ʻO ka mea hou aʻe, hoʻohana ʻo COB i ka ʻenehana uhi maʻamau kiʻekiʻe e pale ai i ka hāʻule ʻana o ka hōʻike LED i hoʻokumu ʻia e ka wai, ka wai, ka UV, a me nā pōʻino ʻē aʻe.
Kākoʻo ia i ka hana o ka wā āpau a hiki ke hana i nā mahana wela ma -30 a +80 degere.
ʻO ke kaʻina hana hoʻomalu āpau e pale ai i nā kuʻi ʻana a i ʻole nā ʻōpala.
Hiki ke hoʻomaʻemaʻe ʻia nā pale hōʻike mini LED me kahi lole pulu inā haumia.
Me ka ʻike ma luna, ʻike paha ʻoe ʻoi aku ka ʻenehana COB ma mua o ka ʻenehana SMD ma ka pale hōʻike LED.
A inā ʻoe e ʻimi neiNā hōʻikeʻike LED micro, hiki iā ʻoe ke kuhikuhi i kekahi mau huahana o YONWAYTECH LED DISPLAY.
E kamaʻilio me YONWAYTECH LED DISPLAY kime no nā kikoʻī hou aku e ʻoluʻolu.
