ʻO Rogers PCB vs FR4 PCB: He hoʻohālikelike o nā waiwai a me nā mea waiwai

He mea koʻikoʻi ka ʻike ʻana i ka ʻokoʻa ma waena o nā ʻano like ʻole i ke koho ʻana i ka papa kaapuni paʻi pono (PCB) no kāu mea uila. ʻElua mau koho kaulana ma ka mākeke i kēia lā ʻo Rogers PCB a me FR4 PCB. ʻOiai he mau hana like nā mea ʻelua, loaʻa iā lākou nā waiwai like ʻole a me nā haku mele, hiki ke hoʻopilikia nui i kā lākou hana. Ma ʻaneʻi e hana mākou i kahi hoʻohālikelike hohonu o Rogers PCBs a me FR4 PCB e kōkua iā ʻoe e hoʻoholo i ka ʻike no kāu papahana aʻe.

1. Mea haku mele:

ʻO ka papa PCB Rogers he mau laminates piha piha piha i ka nui me nā waiwai uila maikaʻi loa e like me ka haʻahaʻa haʻahaʻa dielectric a me ke kiʻekiʻe thermal conductivity. Ma ka ʻaoʻao ʻē aʻe, ʻo FR4 PCB papa, ʻike ʻia ʻo Flame Retardant 4, i hana ʻia me ke aniani fiber reinforced epoxy resin material. Ua ʻike ʻia ʻo FR4 no kāna hoʻokaʻawale uila maikaʻi a me ke kūpaʻa mechanical.

2. Dielectric mau a me ka dissipation kumu:

ʻO kekahi o nā ʻokoʻa nui ma waena o ka papa kaapuni ʻo Rogers a me ka papa kaapuni FR4 ʻo kā lākou dielectric mau (DK) a me ka dissipation factor (DF). Loaʻa i nā Rogers PCB nā DK a me DF haʻahaʻa i kūpono no nā noi alapine kiʻekiʻe kahi koʻikoʻi ka hōʻailona hōʻailona. Ma ka ʻaoʻao ʻē aʻe, ʻo ka papa kaapuni paʻi FR4 he DK kiʻekiʻe a me DF, ʻaʻole kūpono paha ia no nā kaapuni kiʻekiʻe e koi ana i ka manawa kūpono a me ka hoʻouna ʻana.

3. Kiʻekiʻe alapine hana:

Hoʻonohonoho pono ʻia nā papa kaapuni paʻi Rogers e mālama i nā hōʻailona alapine kiʻekiʻe a mālama i ko lākou kūpaʻa. ʻO kona poho dielectric haʻahaʻa e hōʻemi i ka nalowale o ka hōʻailona a me ka distortion, e lilo ia i koho maikaʻi loa no nā noi microwave a me RF. ʻO nā kaʻapuni FR4 PCB, ʻoiai ʻaʻole i hoʻopaʻa ʻia no nā alapine kiʻekiʻe e like me ka papa kaapuni ʻo Rogers PCBs, ua kūpono no nā noi maʻamau a me nā noi waena.

4. Hooponopono wela:

Ma ke ʻano o ka hoʻokele wela, ʻoi aku ka maikaʻi o Rogers PCB ma mua o FR4 paʻi kaapuni. Hiki i kāna conductivity thermal kiʻekiʻe ke hoʻopau i ka wela, kūpono ia no nā noi mana a i ʻole nā ​​​​mea hana e hoʻohua ai i ka wela. He haʻahaʻa ka haʻahaʻa haʻahaʻa o nā PCB FR4, hiki ke alakaʻi i nā mahana hana kiʻekiʻe a koi aku i nā mīkini hoʻomaha hou.

5. Nā kumu kūʻai:

He mea koʻikoʻi ke kumukūʻai e noʻonoʻo ai i ke koho ʻana ma waena o nā kaapuni paʻi Rogers a me nā PCB FR4. ʻOi aku ka nui o ke kumukūʻai o Rogers PCB ma muli o kā lākou haku mele kūikawā a me ka hoʻonui ʻana i ka hana.

6. Mechanical ikaika a me ka lōʻihi:

ʻOiai ʻo Rogers PCB a me FR4 PCB ka ikaika mechanical a me ka lōʻihi, ʻoi aku ka kiʻekiʻe o Rogers PCB ma muli o kāna laminate i hoʻopiha ʻia. ʻO kēia ka mea e emi ai ka deform a i ʻole ke pio ma lalo o ke kaomi. He koho paʻa ka FR4 PCB no ka hapa nui o nā noi, ʻoiai e koi ʻia ka hoʻoikaika hou ʻana no nā kaiapuni ʻoi aku ka paʻakikī.
Ma muli o ka loiloi ma luna, hiki ke hoʻoholo ʻia ʻo ka koho ma waena o Rogers PCBs a me FR4 PCB ma muli o nā koi kikoʻī o kāu papahana. Inā ʻoe e hana nei i nā noi alapine kiʻekiʻe e koi ai i ka hōʻailona hōʻailona maikaʻi a me ka hoʻokele wela, ʻoi aku ka maikaʻi o Rogers PCBs, ʻoiai ke kumu kūʻai kiʻekiʻe. Ma ka ʻaoʻao ʻē aʻe, inā ʻoe e ʻimi nei i kahi hopena kumu kūʻai no ke kumu nui a i ʻole nā ​​​​kaulike waena, hiki i nā FR4 PCB ke hoʻokō i kāu mau koi ʻoiai e hāʻawi ana i ka ikaika mechanical maikaʻi. ʻO ka mea hope loa, ʻo ka hoʻomaopopo ʻana i nā waiwai a me nā mea i haku ʻia o kēia mau ʻano PCB e kōkua iā ʻoe e hana i nā hoʻoholo ʻike e kūpono i kāu mau pono papahana.
