He aha nā mea i hoʻohana ʻia i nā Papa paʻa paʻa?

ʻO kekahi ʻano papa kaapuni e ulu nui nei i ka ʻoihana uila ʻo ia kapapa ʻoʻoleʻa.

I ka pili ʻana i nā mea uila e like me nā smartphones a me nā kamepiula, ʻo ka hana o loko e like me ka mea nui e like me ke ʻano o waho. ʻO nā ʻāpana e hana i kēia mau mea hana e hūnā pinepine ʻia ma lalo o nā papa kaapuni e hōʻoia i kā lākou hana a me ka lōʻihi. Akā he aha nā mea i hoʻohana ʻia i kēia mau papa kaapuni hou?

ʻO ka PCB paʻa-pololeihoʻohui i nā pono o nā papa kaapuni paʻa a maʻalahi, e hāʻawi ana i kahi hopena kūikawā no nā mea pono e pono ai ka hui pū ʻana o ka ikaika mechanical a me ka maʻalahi. Pono pono kēia mau papa i nā noi e pili ana i nā hoʻolālā ʻekolu-dimensional paʻakikī a i ʻole nā ​​​​mea hana e koi ai i ka pelu pinepine ʻana a i ʻole ke kulou ʻana.

E nānā pono kākou i nā mea i hoʻohana mau ʻia i ka hana PCB rigid-flex:

1. FR-4: ʻO FR-4 kahi mea epoxy laminate i hoʻopaʻa ʻia i ka lapalapa ahi i hoʻohana nui ʻia i ka ʻoihana uila. ʻO ia ka mea hoʻohana maʻamau i hoʻohana ʻia ma nā PCB rigid-flex. Loaʻa iā FR-4 nā waiwai insulation uila maikaʻi a me ka ikaika mechanical maikaʻi, kūpono ia no nā ʻāpana paʻa o nā papa kaapuni.

2. Polyimide: ʻO ka Polyimide he polymer kū'ē i ka wela i hoʻohana pinepineʻia ma keʻano he mea hoʻololi maʻalahi i nā papa paʻa. Loaʻa iā ia ke kūpaʻa wela maikaʻi loa, nā waiwai insulation uila a me ka maʻalahi mechanical, e ʻae iā ia e pale i ka piʻo pinepine ʻana a me ka kuʻi ʻana me ka ʻole o ka hoʻopaʻapaʻa ʻana i ka pono o ka papa kaapuni.

3. Copper: ʻO Copper ka mea conductive nui i nā papa paʻa-flex. Hoʻohana ʻia ia e hana i nā ala conductive a me nā pilina e hiki ai ke kahe uila ma waena o nā ʻāpana ma kahi papa kaapuni. ʻOi aku ka maikaʻi o ke keleawe ma muli o kona conductivity kiʻekiʻe, maikaʻi solderability a me ke kumu kūʻai.

4. Adhesive: Hoʻohana ʻia ka mea hoʻopili e hoʻopaʻa i nā ʻāpana paʻa a me ka maʻalahi o ka PCB. He mea koʻikoʻi ke koho ʻana i kahi adhesive hiki ke kū i nā koʻikoʻi wela a me nā mīkini i loaʻa i ka wā o ka hana hana a me ke ola o nā lako. Hoʻohana mau ʻia nā mea hoʻopili Thermoset, e like me ka epoxy resins i nā PCB rigid-flex ma muli o ko lākou mau waiwai paʻa maikaʻi a me ke kūpaʻa wela kiʻekiʻe.

5. Coverlay: ʻO Coverlay kahi pale pale i hoʻohana ʻia e uhi i ka ʻāpana maʻalahi o ka papa kaapuni. Hana ʻia ia mai ka polyimide a i ʻole kekahi mea maʻalahi like ʻole a hoʻohana ʻia e pale i nā ʻāpana palupalu a me nā ʻāpana mai nā mea kūlohelohe e like me ka wai a me ka lepo.

6. Solder mask: ʻO ka solder mask he papa pale i uhi ʻia ma ka ʻaoʻao paʻa o ka PCB. Kōkua ia i ka pale ʻana i ka solder bridging a me nā pōkole uila me ka hāʻawi ʻana i ka insulation a me ka pale corrosion.

ʻO kēia nā mea nui i hoʻohana ʻia i ka hana PCB paʻa.Eia nō naʻe, pono e hoʻomaopopo ʻia e ʻokoʻa paha nā mea kikoʻī a me kā lākou mau waiwai ma muli o ka noi o ka papa a me ka hana i makemake ʻia. Hoʻopili pinepine nā mea hana i nā mea i hoʻohana ʻia i nā PCB rigid-flex e hoʻokō i nā koi kikoʻī o ka hāmeʻa a lākou e hoʻohana ai.

I ka hōʻuluʻulu manaʻo,ʻO nā PCB rigid-flex he mea hou i ka ʻoihana uila, hāʻawi i kahi hui kūʻokoʻa o ka ikaika mechanical a me ka maʻalahi. ʻO nā mea i hoʻohana ʻia e like me FR-4, polyimide, copper, adhesives, overlays, a me solder masks he mea nui i ka hana a me ka lōʻihi o kēia mau papa. Ma ka hoʻomaopopo ʻana i nā mea i hoʻohana ʻia i loko o nā PCB rigid-flex, hiki i nā mea hana a me nā mea hoʻolālā ke hana i nā mea uila kiʻekiʻe a hilinaʻi e hoʻokō i nā koi o ka honua i alakaʻi ʻia e ka ʻenehana.
