Hoʻonui ka noi MCPCB i ka hana a me ka hilinaʻi o UV LED

Ma ke kahua o nā LED UV, he mea nui ka noi ʻana o Metal Core Printed Circuit Board (MCPCB) i ka hoʻomaikaʻi ʻana i ka hana, ka hoʻokele wela a me ka hilinaʻi holoʻokoʻa o nā huahana.

Hoʻopau wela maikaʻi

He mea maikaʻi loa ka MCPCB i ka hoʻopau ʻana i ka wela, e hōʻoia ana i ka hana maikaʻi loa a me ka lōʻihi o nā kukui LED UV. ʻO ka mea metala o ka MCPCB ka mea maʻamau i hana ʻia me ka alumini a i ʻole ke keleawe me ka conductivity thermal kiʻekiʻe. ʻO kēia conductivity thermal kūikawā e hiki ai i ka wela i hana ʻia e hoʻopau koke, e pale ana i ka hoʻokumu ʻana o ka wela a me ka hōʻoia i ka hana ʻana o nā mea hana i loko o ka pae wela maikaʻi loa.

Hoʻonui i ka hana wela

ʻO ka conductivity thermal o MCPCB ma kahi o 10 mau manawa ma mua o FR4PCB. Kōkua ʻo MCPCB e hoʻokō i ka hāʻawi ʻana i ka mahana like ʻole a hōʻemi i ka pilikia o nā wahi wela a me ke kaumaha wela ma kaNā kukui LED UV.ʻO ka hopena, mālama nā kukui i kā lākou hana maikaʻi loa a me ka hilinaʻi kiʻekiʻe a hiki i nā wā lōʻihi o ka hana.

Hoʻomaikaʻi i ka hilinaʻi

Hāʻawi ʻo MCPCB i ka ikaika mechanical a me ka paʻa wela. No ka laʻana, hiki ke hoʻohālikelike ʻia ka coefficient o ka hoʻonui wela (CTE) o ka MCPCB me nā LED UV, e hōʻemi ana i ka pilikia o ka hiki ʻole o ka mīkini ma muli o ka like ʻole o ka wela. 

Hoʻokohu Uila

Hāʻawi ka MCPCB i ka pale uila ma waena o ke kumu metala a me nā papa kaapuni e hōʻoia i ka hana palekana a hilinaʻi o nā ʻōnaehana LED UV. Hana ʻia ka papa dielectric i nā mea e like me ka epoxy resin a i ʻole thermally conductive fluid (TCF), ka mea e hāʻawi ai i ka voltage breakdown kiʻekiʻe a me ke kūpaʻa insulation. Hoʻemi ʻia kēia insulation uila i ka pilikia o nā pōkole pōkole a i ʻole ka leo uila, e pale ana i ka ʻōnaehana mai ka pōʻino.

Hoʻonui i ka hana

Ma ka hoʻohui ʻana i ka MCPCB, hiki i nā mea hana ke hoʻoikaika i ka hana o kā lākouNā lako uila UV. ʻO ka hoʻokuʻu ʻana o ka wela a me ka conductivity thermal o MCPCB e ʻae i ka LED UV e hana i ka hana kiʻekiʻe. ʻO kēia hana e hōʻoiaʻiʻo i ka hoʻopuka UV mau, e hana ana i ka MCPCB kūpono no nā ʻano noi UV.
