Hoʻopili i kahi loea e kau i nā ʻāpana like ʻole ma ka ʻili o kahi papa paʻi LED e hoʻohana ana i nā lakohana hana kūikawā.

  1. ʻAha Pūnaewele

Koho, a hoʻohana ʻia nā pono pono / mīkini i kēia ʻano hana. Maʻamau, Hoʻohui ʻia kahi nozī kikoʻī me kahi puʻupuʻu puʻupuʻu e hana i ka hana. Hoʻohana maʻamau no ka ʻenehana mauna i luna.

Nā Luʻi a me ka Hoʻoholo o ke kaʻina Alakaʻi PCB LED

E like me nā kaʻina hana ʻē aʻe, LED PCB Assembly faces challenges that our experts have identified and provided solutions in this guide. ʻO ke poʻo e aʻo hou aʻe.

7 Nā ala e hōʻalo ai i nā LED Setbacks PCB Assembly

Pehea e hōʻalo ai i nā hoʻonohonoho hoʻonohonoho LED
1. ʻ .pala kaapuni
Kū kēia i ka wā i loaʻa iā ʻoe nā pads kiʻekiʻe-kiʻekiʻe, ʻano nui ma ka ʻaoʻao LED. ʻO ka hōʻemi ʻana i ka pitch laina ke ala ʻoi loa e hoʻopuni ai i kēia pilikia mai ka mea e hoʻonui ʻo ia i ka huina ma waena o ka laina a me ka pale.
2. Papa Kuhikuhi Pad
Ke kaulike i nā pads i kahi moena, Loaʻa paha nā lakio hoʻokaʻawale kiʻekiʻe. ʻO ka maʻa e paʻa i ka kaohi kaʻina hana e kaohi i kēia mau hewa.
3. Nā hana hoʻohaʻahaʻa
Hana ʻia kēia ke holo ʻole ka lālani LED āpau i ka matrix. ʻO ke ala ʻoi loa e hoʻonā i kēia ma ka luku ʻana i nā ʻāpana i hoʻopili ʻia a i ʻole ka wehe ʻana i ka aila mask mask.
4. ʻIli ʻaihue maka mask
Kū mau kēia mai ka hōʻike ʻana i ka ikehu. Hiki ke hoʻonā ʻia ma o ka hōʻike lua ʻana (ka mea e hiki ai i ka hopena o ka lawe mask mask).
5. Hana kūpono ʻole i ka waihoʻoluʻu ʻaila mask Solder
ʻO nā kūlana hana koʻikoʻi a me nā mea nui ke kuleana nui i kēia. Hiki ke hōʻalo ʻia e ke koho ʻana i nā palena palena ʻoi loa a me nā ʻenehana.
6. Nā ʻĀina Angle Papa
Kū aʻe ia mai ka loaʻa ʻana o kahi papa me nā ʻaoʻao ʻaoʻao palupalu a i ʻole he mānoanoa kiʻekiʻe. ʻO ka hoʻoponopono ʻana i kēia pilikia he maʻalahi e like me ka hoʻohui ʻana i kahi pā kumu, lawelawe ia ma ke ʻano he pale pale.
7. ʻO Warpage
Kū kēia i ka wā i loaʻa i nā papa nā pads kiʻekiʻena kiʻekiʻe, me ka ʻaoʻao hoʻokele me nā poloka keleawe nui. ʻO ka maʻa e nānā i ka hoʻokō ʻana i ka pālahalaha ma o ka hōʻemi ʻana i ka warpage ma lalo 0.5%

Ke Kūkulu Kumu o LED PCB

ʻO ka hoʻonohonoho, hoʻolālā, a me nā mea hana a ka mea hana e hoʻohana ai no kāu mau papa āpau i ka noi i manaʻo ʻia. ʻO kahi ʻāpana i hiki ke hana a haki paha i kāu papahana LED ke kumu o nā papa kaapuni. Hiki ke hana i nā papa mai nā ʻano nui like ʻole, e komo pū ana:

  • FR-4:e like me kekahi o nā lako papa PCB hoʻohana pinepine ʻia, Aia ka FR-4 i ka epoxy a me ke aniani. ʻOiai he ahi ke ahi, ʻaʻole kūpono i ka hoʻolilo wela.
  • Mīkini-hao:kēia ʻano PCB me nā alumina i hoʻopili ʻia i lamineka ʻia me ke keleawe. Kūpono kēia mau PCB i nā noi e pili ana i ka conductivity mehana, hoʻoili wela, a me / a i ʻole ka uila uila.
  • Epoxies:ʻoiai ʻaʻole kūpaʻa lākou e like me nā mea ʻē aʻe ke pili i ka hoʻopili ʻana iā lākou ma nā papa PCB, ʻoi aku ka uku o kā lākou hana ʻana.

No ka mea he mea nui ka hoʻolilo wela no ka hana o nā papa PCB LED, hoʻohana pinepine ʻia nā metala e like me nā mea nui

ʻO LED Rula Hoʻolālā PCB

ʻElua mau lula e ukali ai i ka hoʻolālā ʻana i nā PCB LED. O ka mea mua loa, e hōʻoia e noho pono nā LED ma nā puka kaapuni a hoʻokomo i nā lua ma ke ʻāpana o ka hoʻolālā. ʻO ka lua, ʻike i ka mamao ma waena o nā lua. Kūpono, i ka mana i ka LED, pono ʻoe i kahi palena iki ma waena o nā terminal maikaʻi ʻole a maikaʻi a me nā lua.

ʻO ka hana hou e mālama i ka faila hoʻolālā i ka faila faila Gerber (ʻoihana maʻamau o ka ʻoihana). Pono ka faila Gerber e hōʻike i nā papa PCB āpau e like me kēlā me kēia papa e hōʻike nei i kahi ʻokoʻa ʻokoʻa. Pono ʻoe e mālama i nā ana a me nā ʻikepili papa o kāu hoʻolālā PCB i kahi faila faila. E hoʻouna i ka faile ʻelua a me ka faila Gerber i ka mea hana pilikino LED PCB āu i koho ai.

Ke kūʻai aku ʻoe i kāu mau LED, hōʻoia e kūlike lākou i kāu kikoʻī. E kū maʻalahi hoʻi nā LED i ka mana a kāu SMD LED PCB papa e hoʻolako ai

He aha nā ʻenehana hoʻolālā i noi ʻia no ka LED PCB Assembling?

  1. Kuʻi

Hoʻohana nui ʻia kēia ala ma nā hōʻike LED, ka mea maʻamau i kahi hoʻolālā waho kūmole. Ma ka papa keleawe, ua hoʻopiha kekahi ʻaoʻao i nā pads i hoʻonohonoho ʻia i loko o kahi moena, i kapa ʻia ʻo ka papa LED. ʻO nā ʻaoʻao ʻē aʻe nā ʻāpana keleawe – i kapa ʻia ʻo ka ʻaoʻao hoʻokele. ʻO kahi pitch LED liʻiliʻi ʻo ia ka hoʻonā a me ka hōʻike ʻoi aku ka maikaʻi. Pili kēia hoʻolālā i nā kikoʻī LED pad.

  1. Nā Laki Hoʻokomo LED

ʻAʻole komo nā lua ma nā papa PCB a loaʻa ke anawaena o ko lākou hoʻomanawanui ʻana ma ka plus / minus 0.05mm. ʻAʻole pono ka hohonu o nā lua ma waho o ka mānoanoa o ka papa i hoʻoliʻiliʻi ʻia 0.5mm me ke ahonui o ka plus / minus 0.2mm. Aia ka ʻanuʻu ʻeli maʻamau i 130 °.

  1. Ka mamao ma waena o nā palena kūwaho a me nā pale

Pono e lawa ka hakahaka ma waena o ka palena i waho a me nā pale palena, a i ʻole e hoʻomohala ka PCB LED e like me ka pā keleawe a me nā hemahema o ka wili ʻana.

ʻO ka hoʻāʻo ʻana o LED PCB

ʻOiai he nui nā mīkini i hoʻohana ʻia i ka pae hoʻāʻo, ʻo ka mīkini i hoʻohana mau ʻia ka mīkini optika automated. Nānā inā aia he mau hewa i hana ʻia i ka hui ʻana o nā papa PCB LED, mai nā pilikia me nā hui solder i nā pilikia me nā mea papa. Hiki i kekahi o kēia mau pilikia ke hopena i ka maikaʻi o ka hoʻopili subpar a i ʻole ʻaʻohe pili i nā hihia ʻoi loa.

Hiki i nā mea kuhi hewa ke hoʻopili maʻalahi i ka ʻāpana o ka papa ʻaʻole lākou e pili pono, ʻo ia ke kumu e pono ai ka hoʻāʻo. ʻO nā ala ʻē aʻe no ka hoʻāʻo ʻana i nā papa PCB no nā kukui LED me nā nānā X-ray automate a me nā loiloi lima.

Packaging kēlā me kēia LED PCB Papa ma hope o ka ʻAha

Hōʻike ka ʻūlū e hoʻopili ʻia nā ʻāpana uila electrolyte me nā LED waho. ʻO nā mea ʻē aʻe ma mua o ka hāʻawi ʻana i ka pale chip, hōʻoia kēia makaʻala i optimised LED luminance kukui. Mālama pū ʻia ka lawe ʻana o ke kukui i ʻike ʻia me ka mālama ʻana i ka hana maʻamau o nā ʻāpana diode.

Mīkini no ka Packaging LED PCB

Ua kapa ʻia ka hāmeʻa e hoʻohana i ka hoʻopili PC ma luna o ka ʻili i kahi mīkini aniani paʻa paʻa. Pono e waiho i nā papa LED i loko o ka pūʻali me ke akahele e hōʻalo i ka hoʻopili luminescence. Hiki i nā hana hōʻiliʻili maikaʻi ʻole ke hopena maʻalahi i nā pilikia me ka ʻōlinolino o ka LED

Nā ʻAno Packaging LED

  • ʻO LED uila kiʻekiʻe
  • LED ʻaoʻao
  • LED Flip chip
  • ʻO LED uila
  • Alakaʻi kukui
  • ʻO LED kiʻekiʻe

He aha nā papa PCBs LED i hoʻopili ʻia a pehea e hana ai?

Pono nā PCB i ka hana o nā kukui LED. ʻO lākou nā papa kahi e hoʻopili ʻia ai nā ʻāpana LED. Hiki iā lākou ke hana mai kahi ākea o nā mea, e like me ka fiberglass a me ka mea hao. ʻO nā mea ʻē aʻe ma mua o ke kākoʻo kino ʻana i nā ipukui LED, ʻo kēia mau papa PCB no nā kukui LED e kōkua i ka hoʻolilo wela mai nā mea uila.

ʻAʻole kēia e pale wale i ko lākou hōʻino akā hoʻonui pū i kā lākou hana. No ka hana kūpono o ka hoʻolālā papa PCB LED, pono ʻoe e hoʻopaʻa i ke kumu pālolo a me ka poho wela mehana me kahi ʻāpana e hana i ka mālamalama ke holo ka uila ma waena o ka papa kaapuni.

Ehia mau kumukūʻai e hoʻolālā ai i kahi PCB?

ʻO ke kumukūʻai o LED PCB e hana ana / e ʻākoakoa ʻokoʻa ana mai kahi mea hana i kekahi. ʻO laki kahi nui o nā helu helu pūnaewele hiki ke kōkua iā ʻoe e helu i ke kumukūʻai o kāu papahana. Kūpono, nā kumu e hoʻopili i ka uku hope loa me ka hana, nui, wā kuhikuhi lawe, a me ka ʻenehana i hoʻohana ʻia.

Kaukaʻi ʻia i kāu helu kūpono o nā anakahi, hiki ke hāʻule ke kumukūʻai o ka hui PCB ma kahi āpau $10 a $50. Eia naʻe, he kuhi kuhi kēia kēia no ka mea ʻokoʻa ke kumukūʻai ma waena o nā mea hana. E waiho wale, ke kiʻi ʻana i kahi ʻōlelo pololei mai ka mea hana ke ala ʻoi loa e koho ai i ke kumukūʻai.

Inā ʻoe e ʻimi ana e ʻoki i kēia kumukūʻai, e noʻonoʻo e ʻae i kahi leeway lawe a hoʻonohonoho i nā nui he nui. ʻOiai hele mai nā kauoha nui me nā uku hōʻemi, hiki i nā manawa kau lōʻihi ke ʻike iā ʻoe i kahi haki kumukūʻai. Ma luna o nā mea āpau, hōʻoia e hoʻāʻo i kāu mau papa kaapuni LED – ʻO nā truf maikaʻi ke kumu kūʻai i kēlā me kēia lā.

He aha ke kukui LED i makemake nui ʻia no kou mau maka?

Pono ka mālama maka inā makemake ʻoe e hoʻonui i kou olakino maka. Kūpono, ʻo nā kukui LED maikaʻi loa no kou mau maka kekahi mea e hoʻohālike i ke ao. Koho i nā ʻūlū LED i kū ka mahana o ke anilā ma 5000-6500K ʻoiai kēia ka wela o ke ao maʻamau. E nānā kūlohelohe nā kala a pau, ʻaʻole e haʻi aku ʻaʻole e luhi ka maka o kou mau maka.

Pehea e koho ai i kahi mea hoʻolako PCB LED

ʻOiai he mea nui ke kumukūʻai i ke koho ʻana i nā mea hoʻolako i ka LED PCB, ʻo ia wale nō ka mea nui e nānā. E kālele ana i ka waiwai i hāʻawi ʻia i kā lākou lawelawe ʻo LED PCB i kāu papahana. O kahi laʻana, ehia mau kālā hoʻopukapuka a lākou i hana ai i mea e ulu ai ka noiʻi? Eia kekahi mau ala e ʻike ai i nā mea hoʻolako nui:

  • E noi i kā lākou mea kūʻai aku ma mua no ka loiloi.
  • Loiloi i ka wikiwiki o kā lākou hui kākoʻo mea kūʻai aku i ka pane ʻana aku i nā mea kūʻai aku.
  • E hoʻāʻo i ka maikaʻi o kā lākou mau papa kaapuni
  • E nīnau e pili ana i nā manawa maʻamau e hoʻouna ai e like me kāu.
  • E nīnau inā hiki iā lākou ke hāʻawi maʻalahi i ka nui o kāu ʻoka PCB LED.
  • E kamaʻilio me lākou e pili ana i nā uku hōʻemi a me nā haʻihaʻi kumukūʻai.

E hāʻawi i kāu mea kūʻai aku i kahi maluhia o ka noʻonoʻo me nā kukui LED

ʻAʻohe palena i ka mea a nā kukui LED e hiki ai ke hana, mai ka hoʻomālamalama ʻana i nā ʻohana e kōkua i ka ulu ʻana o nā mea kanu. Me ka pono e hāʻawi ai nā kukui LED, lōʻihi kēia mau kukui. ʻO ko lākou ʻano kūlohelohe kūpono iā lākou e kūpono no ka hoʻohana ʻana i ka honua e mālama nei i ka mālama ʻana i ke kaiapuni.

No ke aha e koho ai iā mākou no ka LED PCB Assembly

Me ʻoi 14 makahiki o ka ʻike i ka hana PCB a me ka ʻoihana hui, hiki iā ʻoe ke hilinaʻi iā mākou e hāʻawi i kekahi mea ʻoi iki i nā papa kaapuni LED paʻi kiʻekiʻe, hālāwai i kāu kumukūʻai a me nā kikoʻī a hāʻawi i kāu PCB i ka manawa ma kahi āu e makemake ai. Hāʻawi mākou i nā lawelawe papa alakaʻi PCB nui. Over ka makahiki, ua hana mākou i nā PCB he nui ʻole me nā hoʻolālā ʻokoʻa no nā mea kūʻai aku ʻokoʻa. Hoʻokomo pū lākou iā UV LED PCBA no ka mīkini lapaʻau, UV LED PCBA no ka mea paʻi 3D, AC220V driverless LED PCBA, AC110V driverless LED PCBA, ʻO LED PCBA no ke kukui alanui, ʻO LED PCBA no ke kukui Tube, ʻO LED PCBA no ka mālamalama o ka panela, ʻO COB RGB LED PCBA no ke kukui wai, ʻO RGB LED PCBA no ka kukui pixel, ʻO LED PCBA no ke kukui kaupaku, ʻO LED PCBA no ke kukui kalepa, a me nā mea hou aku.

He loea mākou i nā ʻano hana like ʻole o LED PCB Assembly me nā pono hana a me nā pono hana e hōʻoia i ka maikaʻi o ka LED PCB a ʻoi aku ka lōʻihi..

Kāhea aku iā MOKOLight i kēia lā no ke kōkua me kāu pono PCB LED.
