1. Hoʻolauna
Hāʻawi nā Pandawill Circuits i ka maikaʻi o ke alumini a me FR4 i ka papa kaapuni no nā kukui LED a me nā noi hōʻike LED.
Hoʻohana ʻia lākou i:
ʻO nā kukui kukui linear laina
Uila kaʻa
Nā noi moana
Nā noi uila
Kaʻa / Alanui Alanui
Nā Scoreboards / pale pale wikiō a pēlā aku
Me nā makahiki he 10 i ka LED PCB, hiki iā mākou ke hāʻawi i ke koho maikaʻi loa o nā mea, nā hoʻopau solderable a me nā paona keleawe e hālāwai a ʻoi aku i ka hana a me nā pae hilinaʻi wā lōʻihi e pono ai no nā ʻenehana hoʻokumu LED. ʻO kā Pandawill hoʻokokoke ʻana i nā noi uila LED e nānā i kēlā me kēia ʻano o ka hoʻolālā a me ka hoʻohui ʻana o ka papa kaapuni.
1. He aha nā mea pono ke kūʻai aku e hāʻawi aku i nā kikoʻī like a i ʻole kiʻekiʻe no ka uku haʻahaʻa?
2. Pehea e hoʻopili ʻia ai nā papa e hana i ka hua nui mai ka papa hana?
3. Pehea e hoʻohana ai i ka hoʻokele a me ka helu ʻana i ka panal i nā papa e hāʻawi i ka ʻoi aku ka paʻakikī no ka paneli hana a hoʻemi i ka nui o ka hana ma hope o ka hoʻopau ʻana?
4.Which kahi i hoʻopau ai e hāʻawi i ka hana maikaʻi loa no kāu kaʻina hālāwai i koho ʻia.
5.Wa aha ke kaupaona keleawe maikaʻi e hāʻawi i ka hilinaʻi lōʻihi e koi ʻia e kūlike i ke ola i manaʻo ʻia o ka huahana kukui LED.
6. He aha ke kala, ka hoʻopau (gloss a i ʻole ka matte) a me ka kikoʻī o ka pale solder e pono ai e hoʻohana a hoʻopau i ka nui o ke kukui ākea / ka wela, a i ʻole mālama i ka ʻōlinolino o ke keʻokeʻo e hōʻike i ka mālamalama e like me ka hiki ke loaʻa ʻole ka discoloration?
7. Ka maikaʻi o ka pale silika a me ka hoʻopau ʻana i hōʻike maikaʻi ʻia nā kuhikuhi a ka mea hoʻonoho.
Mīkini Kora PCB
ʻO kahi Papa Kālā Kī Kī KīWī (MCPCB), a i ʻole PCB pumehana, kahi ʻano o PCB i loaʻa kahi mea hao e like me ke kumu no ka ʻāpana pāhana wela o ka papa. ʻO ke kumu o ke kumu o ka MCPCB e hoʻohuli hou i ka wela mai nā mea papa koʻikoʻi a i nā wahi liʻiliʻi e like me ke kākoʻo heatsink metala a i ʻole ke kumu kila. Hoʻohana ʻia nā metala ma MCPCB ma ke ʻano he koho i nā papa FR4 a i ʻole CEM3.
Nā Mea Pono PCB Metal Core a me ka mānoanoa
Hiki i ke kinikini metala o ka PCB pumehana ke aluminika (aluminika core PCB), keleawe (PCB keleawe keleawe a i ʻole PCB keleawe kaumaha) a i ʻole ka huikau o nā ʻāpana kūikawā. ʻO ka mea maʻamau ka PCB kumu alumini.
ʻO ka mānoanoa o nā metala metala ma nā pā waihona PCB he 30 mil - 125 mil ka nui, akā hiki ke ʻoi aku ka lahilahi a me ka lahilahi o nā pā.
MCPCB keleawe pepa kini mānoanoa hiki i 1 - 10 oz.
Nā pōmaikaʻi o MCPCB
Hiki i nā MCPCB ke keu pono e hoʻohana no ko lākou hiki ke hoʻohui i kahi papa polymer dielectric me kahi conductivity wela kiʻekiʻe no kahi pale kūpanaha haʻahaʻa.
Hoʻololi nā PCB kumu nui i ka wela 8 a 9 mau manawa wikiwiki ma mua o FR4 PCB. MCPCB laminates hoʻopau i ka wela, mālama i ka hoʻomehana ʻana i nā ʻenehana i nā hopena i hoʻonui ʻia ka hana a me ke ola.
