Pākuʻi-nui PCBi ke kamaʻilio ʻana, ka lāʻau lapaʻau, ka mana ʻoihana, palekana, kaʻa, mana uila, mokulele, pūʻali koa, kamepiula peripheral a me nā ʻano ʻē aʻe e like me ka "core force", ʻoi aku ka nui o nā hana huahana, ʻoi aku ka nui o nā laina paʻa, no laila, ʻoi aku ka paʻakikī o ka hana. ʻoi aku ka nui aʻe.
I kēia manawa, kaNā mea hana PCBHiki i ka hui ke hana i nā papa kaapuni multilayer ma Kina e hele pinepine mai nā ʻoihana ʻē aʻe, a he liʻiliʻi wale nō nā ʻoihana kūloko i loaʻa ka ikaika o ka hui.Multi-layer kaapuni papa hana 'aʻole wale pono kiʻekiʻe 'enehana a me ka lako waiwai hoʻopukapuka kālā, 'oi aku ka 'ike hana a me ka 'ike loea kanaka, i ka manawa like, e loaʻa multi-layer papa mea kūʻai mai palapala hōʻoia, koʻikoʻi a me ka luuluu kaʻina hana, no laila, multi-layer kaapuni papa komo paepae. ʻoi aku ka kiʻekiʻe, ʻoi aku ka lōʻihi o ka hoʻokō ʻana i ka pōʻai hana ʻoihana.ʻO ke kikoʻī, ʻo nā pilikia kaʻina hana i loaʻa i ka hana ʻana o ka papa kaapuni multilayer ʻo ia ka nui o nā ʻano ʻehā.ʻO ka papa kaapuni multilayer i ka hana a me ka hana ʻana i nā pilikia ʻehā.
1. Paʻakikī i ka hana ʻana i ka laina i loko
Loaʻa nā koi kūikawā o ka wikiwiki kiʻekiʻe, ke keleawe mānoanoa, ke alapine kiʻekiʻe a me ka waiwai Tg kiʻekiʻe no nā laina papa multilayer.Ke piʻi aʻe nei nā koi o ka wili o loko a me ka mana kiʻi nui.No ka laʻana, ʻo ka papa hoʻomohala ARM he nui nā laina hōʻailona impedance i ka papa o loko, no laila paʻakikī ke hōʻoia i ka pono o ka impedance i ka hana laina i loko.
Nui nā laina hōʻailona ma ka ʻaoʻao o loko, a ʻo ka laulā a me ka spacing o nā laina ma kahi o 4mil a i ʻole.ʻO ka hana lahilahi o ka pā multi-core he maʻalahi ke wrinkle, a ʻo kēia mau mea e hoʻonui ai i ke kumukūʻai hana o ka papa o loko.
2. Paʻakikī i ke kamaʻilio ʻana ma waena o nā papa o loko
Me ka nui o nā papa o ka pā multilayer, ʻoi aku ka kiʻekiʻe o nā koi o ka ʻaoʻao o loko.E hoʻonui a emi ke kiʻiʻoniʻoni ma lalo o ka mana o ka wela a me ka haʻahaʻa i loko o ka hale hana, a e like ka hoʻonui ʻana a me ka emi ʻana o ka pā kumu i ka wā i hana ʻia ai, ʻoi aku ka paʻakikī o ka hoʻoponopono ʻana i ka pololei o loko.
3. Paʻakikī i ka hana kaomi
ʻO ka superposition o ka multi-sheet core plate a me ka PP (semi-solidified sheet) e maʻalahi i nā pilikia e like me ka waiho ʻana, paheʻe a me ke koena pahu i ke kaomi ʻana.Ma muli o ka nui o nā papa, ʻaʻole hiki ke hoʻomau ka hoʻonui a me ka hoʻohaʻahaʻa ʻana a me ka uku coefficient nui.ʻO ka insulation lahilahi ma waena o nā papa e alakaʻi maʻalahi i ka hemahema o ka hoʻāʻo hilinaʻi ma waena o nā papa.
4. Paʻakikī i ka hana ʻana
Hoʻohana ka pā multi-layer i ka Tg kiʻekiʻe a i ʻole nā palapala kūikawā ʻē aʻe, a ʻokoʻa ke ʻano o ka wili ʻana me nā mea like ʻole, kahi e hoʻonui ai i ka paʻakikī o ka wehe ʻana i ka slag glue i loko o ka lua.ʻO ka PCB multi-layer kiʻekiʻe he kiʻekiʻe ka nui o ka puka, haʻahaʻa haʻahaʻa hana pono, maʻalahi e wāwahi i ka pahi, ʻokoʻa pūnaewele ma o ka lua, kokoke loa ka ʻaoʻao o ka puka e alakaʻi i ka hopena CAF.
No laila, i mea e hōʻoia ai i ka hilinaʻi kiʻekiʻe o ka huahana hope loa, pono i ka mea hana ke hoʻokō i ka mana kūpono i ke kaʻina hana.
