ʻO ka papa keleawe keleaweʻo Copper Clap Clay a me FR-4 heʻelua mau papa i hoʻohanaʻia i ka papa circuit ʻOkoʻa lākou i nāʻano hana o nā mea hana, nā hiʻohiʻona hana a me nā kahua noi. I kēia lā, e hāʻawi ka wikiwiki iāʻoe me kahi loiloi hoʻohālikelike o kēia mau meaʻelua mai kahiʻano loea.

ʻO ka papa keleawe keleawe,ʻo ia kahi kumu o ka mea hana ma keʻano,ʻo ia ka mea maʻamau ʻO kāna hiʻohiʻona nui he maʻiʻino maikaʻiʻole a me ka wela hoʻomehana wela, Pēlā maikaʻi loa i nā noi i koiʻia, e like me ke kukui ke kukui. Hiki i ka mea hao ke hoʻokō pono i ka wela wela mai nā wahi wela o ka PCB i ka papa holoʻokoʻa, i ka hoʻomaikaʻiʻana i ka hana holoʻokoʻa o ka polokalamu.

FR-4: FR-4 he mea laminate i ka lole o ke aniani me ka mea e hoʻoikaika ai i ka mea e like me ka mea e hoʻopili ai. ʻO kēia ka mea maʻamau i hoʻohana pinepineʻiaʻo PCB ma muli o kāna ikaika manuahi, nā waiwai uila a me nā kīʻaha kīʻaha blame. Ua loaʻa iā FR-4 i kahi helu Rustant Roudant o UL94 V-0

Ke kī nui:

Nā Kūlana Kūʻai: Nā Kūlana Kūʻai Kūʻai-Clap e hoʻohana ai i ka metala (e like me ka alumini a iʻole nā ​​copper a me ka epopy fiberglass a me nā epoxs fiberglass

ʻO keʻano o ka Thermal Condertic

ʻO ke kaumaha a me ka mānoanoa:ʻO nā pahu keleawe clad clad copper copper heʻoi aku ka nui ma mua o fr-4 a malia paha.

ʻO ke kaʻina hana: FR-4ʻO ka maʻalahi ke kaʻina hana, kūpono no ka hoʻolālāʻana o ka pcb pricx He paʻakikīʻo Coop Clap Coop Coppe Platte e hana i ke kaʻina, akā kūpono no ka papa hoʻokahi a iʻole ka papa hana maʻamau.

ʻO ke kumukūʻai:ʻO ke kumukūʻai o ke kumukūʻai clad clad clad clad copper iʻoi aku ka kiʻekiʻe ma mua o fr-4 ma muli o ke kumukūʻai kiʻekiʻe kiʻekiʻe.

Nā noi:ʻO nā papa keleawe clad colper i hoʻohana nuiʻia i nā mea uila e pono ai e koi i ka wehe wela, e like me ka uila uila a me nā kukui uila. ʻO ka FR-4ʻoi aku kaʻoi aku ka nui, kūpono no ka hapa nui o nā mea uila uila a me nā hoʻolālā preser print.

Ma ka laulā,ʻo ke koho o ka clad clad a iʻole fr-4 i hilinaʻi nuiʻia i ka hoʻokele hana
