ʻO nā PCB metala kumu i kapa ʻia ʻo MCPCBs, nona ka papa substrate he kumu metala. ʻO nā metala maʻamau o nā MCPCB i hoʻohana ʻia he aluminika, keleawe, a me ke kila kila. ʻO nā PCB ma muli o ka alumini ka mea kūʻai nui loa; Loaʻa lākou i ka conductivity wela maikaʻi a me ka hiki ke hoʻopau wela i nā kumu kūʻai haʻahaʻa. ʻOi aku ka maikaʻi o nā PCB e pili ana i ke keleawe ma mua o ka alumini, akā ʻoi aku ka kiʻekiʻe o ke kumukūʻai. ʻOi aku ka paʻakikī o nā PCB ma muli o nā mea mua ʻelua, ʻoiai me ka conductivity wela haʻahaʻa. Ua ʻike ʻia nā PCB metala e like me ko lākou maikaʻi thermal dissipation.I nā makahiki i hala iho nei, ua hoʻomohala wikiwiki ʻia ka ʻoihana LED, akā ʻo ka pilikia o ka hoʻopau ʻana i ka wela ua puzzling i ka noi a me ka hoʻomohala ʻana o LED, ʻoi aku ka mana kiʻekiʻe LED ma ke kahua o ke kukui. Hāʻawi ka noi ʻana o ka substrate metala i kahi ala hou e hoʻoponopono pono ai i ka hoʻoheheʻe wela o LED.

No ka mea metala kumu kumu, aia nā mea kumu alumini a me keleawe. ʻO ka substrate alumini kahi ʻano o ka pā keleawe i hoʻopaʻa ʻia me ka hoʻoili wela maikaʻi a me ka hana dissipation. ʻOi aku ka maikaʻi o ka hana keleawe ma mua o ka alumini, akā ʻoi aku ka maikaʻi o kona kumukūʻai ma mua o ka alumini.

Ke kauoha pinepine nei nā mea kūʻai aku i nā pcbs aluminika, no ka mea, ʻoi aku ka waiwai o ke kumukūʻai o ka pcb aluminika, hoʻohana ʻia lākou no nā kukui LED, nā mea kani leo a me nā lako uila kamaʻilio.

ʻO kahi papa maʻalahi MCPCB ʻaoʻao hoʻokahi he kumu metala (ʻo ia ka alumini, a i ʻole ke keleawe keleawe), Layer Dielectric (non-conducting) Layer, Copper Circuit Layer, nā ʻāpana IC a me ka mask solder.

ʻO ka hoʻokuʻu ʻana o ka wela maikaʻi o nā PCB metala ʻoi aku ka liʻiliʻi o ka wela kiʻekiʻe, kahi e emi ai ka distortion i ka wā o ka lawe ʻana i nā hōʻailona.

ʻO nā mea maikaʻi i ʻōlelo ʻia ma luna nei e hana i nā PCB metala kumu maikaʻi loa i nā noi he nui, e like me nā mea hoʻololi mana, nā kukui, photovoltaic, nā noi backlight, nā noi LED automotive, nā mea hana home, a pēlā aku. ʻO ka PCB i hoʻokumu ʻia i ka alumini ka ʻano maʻamau o nā PCB koʻikoʻi metala no kāna pono kumukūʻai. ʻOi aku ka nui o nā kukui paʻa, kōkua nā PCB alumini e hoʻokō i nā pae kukui kiʻekiʻe me ka liʻiliʻi o ka LED.

ʻO ka mānoanoa keleawe o ka MCPCB hiki ke 1oz a 10oz, a ʻo ka mānoanoa kumu metala o nā papa he 30mil a 125mil. Hāʻawi ʻo YMS i nā ʻano PCB core metala, a e hoʻokaʻaʻike mai iā mākou inā makemake ʻoe i nā substrates mānoanoa a lahilahi paha. E mālama mau ʻo YMS i kā mākou mau mea hiki a me nā pono hana me ka wikiwiki o nā pae kiʻekiʻe e hāʻawi i nā mea kūʻai aku i nā lawelawe maikaʻi loa o ka PCB prototype, PCB fabrication, component sourcing.
