Nui nā ʻano papa kaapuni ma ka mākeke, a ʻokoʻa nā huaʻōlelo ʻoihana, a ma waena o ka papa fpc i hoʻohana nui ʻia, akā nui ka poʻe i ʻike ʻole i ka papa fpc, no laila he aha ke ʻano o ka papa fpc?

1, ua kapa ʻia ka papa fpc "papa kaapuni maʻalahi", ʻo ia kekahi o ka PCB i paʻi ʻia ka papa kaapuni, kahi ʻano o ka hoʻohana ʻana i nā mea insulating ma ke ʻano he substrate, e like me: polyimide a polyester film, a laila ma o kahi kaʻina hana kūikawā i hana ʻia. o ka papa kaapuni i paiia. He kiʻekiʻe ke kiʻekiʻe o ka mānoanoa uwea o kēia papa kaapuni, akā māmā ke kaumaha, ʻano lahilahi ka mānoanoa, a maikaʻi hoʻi ka hana maʻalahi, a me ka hana kulou maikaʻi.

2, he ʻokoʻa nui ka papa fpc a me ka papa PCB. ʻO ka substrate o ka papa fpc ka mea maʻamau PI, no laila hiki ke hoʻokuʻu wale ʻia, hoʻololi ʻia, a me nā mea ʻē aʻe, ʻoiai ʻo ka substrate o ka papa PCB ma ke ʻano he FR4, no laila ʻaʻole hiki ke hoʻokuʻu wale ʻia. No laila, ʻokoʻa loa ka hoʻohana ʻana a me ka noi ʻana o ka papa fpc a me ka papa PCB.

3, no ka mea hiki i ka papa fpc ke kulou a hoʻololi ʻia, ua hoʻohana nui ʻia ka papa fpc i ke kūlana e pono e hoʻopili pinepine ʻia a i ʻole ka pilina ma waena o nā ʻāpana liʻiliʻi. 'Oko'a ka papa PCB, no laila ua ho'ohana nui 'ia ma kekahi mau wahi 'a'ole pono e kulou a pa'akikī ka ikaika.

4, ʻo ka papa fpc ka maikaʻi o ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, no laila hiki iā ia ke hōʻemi pono i ka nui o nā huahana uila he liʻiliʻi loa, no laila ua hoʻohana nui ʻia i ka ʻoihana kelepona paʻalima, ʻoihana kamepiula, ʻoihana TV, ʻoihana kiʻi kamepiula a me nā mea ʻē aʻe. liʻiliʻi liʻiliʻi, ʻoihana huahana uila maʻalahi.

5, ʻaʻole hiki ke hoʻokuʻu wale ʻia ka papa fpc, akā hiki ke hōʻeha ʻia a hoʻopaʻa ʻia paha, a hiki ke hoʻonohonoho manuahi ʻia e like me nā pono o ka hoʻolālā ākea. I loko o ke ākea ʻekolu, hiki ke hoʻoneʻe ʻia ka papa fpc a i ʻole telescoped, i hiki ke hoʻokō ʻia ke kumu o ka hoʻohui ʻana ma waena o ka uea a me ka hui ʻāpana.

He aha nā kiʻiʻoniʻoni maloʻo PCB?

1, PCB ʻaoʻao hoʻokahi

Hana ʻia ka papa kumu i ka pepa phenol copper laminated board (pepa phenol ma ke kumu, i uhi ʻia me ka copper foil) a me ka pepa Epoxy copper laminated board. Hoʻohana ʻia ka hapa nui o lākou i nā huahana uila kūloko e like me nā lekiō, nā mea hana AV, nā mea hoʻomehana, nā pahu hau, nā mīkini holoi, a me nā mīkini kalepa e like me nā mīkini paʻi, nā mīkini kūʻai aku, nā mīkini kaapuni, a me nā mea uila.

2, PCB ʻaoʻao ʻelua

ʻO nā mea kumu he Glass-Epoxy copper laminated board, GlassComposite copper laminated board, a me ka pepa Epoxy copper laminated board. Hoʻohana ʻia ka hapa nui o lākou i nā kamepiula pilikino, nā mea kani uila, nā kelepona nui, nā mīkini uila automotive, nā peripherals uila, nā mea pāʻani uila, a me nā mea ʻē aʻe. , nā mīkini hoʻolaha ukali, a me nā mīkini kamaʻilio kelepona ma muli o kā lākou mau hiʻohiʻona kiʻekiʻe kiʻekiʻe, a ʻoiaʻiʻo, he kiʻekiʻe ke kumukūʻai.

3, 3-4 papa o PCB

ʻO ke kumu kumu he Glass-Epoxy a i ʻole benzene resin. Hoʻohana nui ʻia i nā kamepiula pilikino, Me (medical electronics, medical electronics) machines, ana mīkini, semiconductor testing machines, NC (NumericControl, numerical control) machines, electronic switches, communication machines, memory circuit boards, IC cards, etc. ʻO ke aniani synthetic copper laminated board e like me nā mea PCB multi-layer, ʻoi aku ka nui o ka nānā ʻana i kāna mau hiʻohiʻona maikaʻi loa.

4,6-8 papa o ka PCB

Hoʻokumu ʻia ka mea kumu ma GLASS-epoxy a i ʻole Glass benzene resin. Hoʻohana ʻia i nā hoʻololi uila, nā mīkini hoʻāʻo semiconductor, nā kamepiula pilikino liʻiliʻi, EWS (EngineeringWorkStation), NC a me nā mīkini ʻē aʻe.

5, ʻoi aku ma mua o 10 mau papa o PCB

Hana ʻia ka substrate me ke aniani benzene resin, a i ʻole GLASS-epoxy ma ke ʻano he nui-layer PCB substrate material. ʻOi aku ka kūikawā o ka noi ʻana o kēia ʻano PCB, ʻo ka hapa nui o lākou he kamepiula nui, kamepiula kiʻekiʻe, nā mīkini kamaʻilio, a me nā mea ʻē aʻe.

6, nā mea ʻē aʻe PCB substrate

ʻO nā mea ʻē aʻe PCB substrate he alumini substrate, hao substrate a pēlā aku. Hoʻokumu ʻia ke kaapuni ma luna o ka substrate, ʻo ka hapa nui o ia mau mea i hoʻohana ʻia i ke kaʻa hoʻohuli (kaʻa liʻiliʻi). Eia kekahi, aia nā PCB maʻalahi (FlexiblPrintCircuitBoard), ua hoʻokumu ʻia ke kaapuni ma ka polymer, polyester a me nā mea nui ʻē aʻe, hiki ke hoʻohana ʻia e like me ka papa hoʻokahi, papa pālua, i ka papa multi-layer hiki ke. Hoʻohana nui ʻia kēia papa kaapuni maʻalahi i nā ʻāpana hoʻoneʻe o nā kāmela, nā mīkini OA, a me nā mea ʻē aʻe, a me ka pilina ma waena o ka PCB paʻakikī a i ʻole ka hui pili pono ma waena o ka PCB paʻakikī a me ka PCB palupalu, e like me ke ʻano o ka hui ʻana ma muli o ke kiʻekiʻe. elasticity, ʻokoʻa kona ʻano.

ʻO ka papa hana nui a me ka pā TG kiʻekiʻe

ʻO ka mea mua, hoʻohana mau ʻia nā papa kaapuni PCB multi-layer i nā wahi hea?

Hoʻohana pinepine ʻia nā papa kaapuni PCB Multilayer i nā lako kamaʻilio, nā mea lapaʻau, ka mālama ʻana i ka ʻoihana, ka palekana, ka uila uila, ka mokulele, nā kula peripheral kamepiula; E like me ka "koʻikoʻi koʻikoʻi" i kēia mau kahua, me ka hoʻonui mau ʻana o nā hana huahana, ʻoi aku ka nui o nā laina ʻoi aku ka nui o nā laina, ʻoi aku ka kiʻekiʻe o ka mākeke kūpono o ka maikaʻi o ka papa. Ke piʻi mau nei nā papa kaapuni TG.

ʻO ka lua, ʻo ke ʻano o nā papa kaapuni PCB multi-layer

E loaʻa i ka papa PCB maʻamau ka deformation a me nā pilikia ʻē aʻe i nā wela kiʻekiʻe, ʻoiai ʻo nā hiʻohiʻona mechanical a me nā hiʻohiʻona uila hiki ke emi loa, e hōʻemi ana i ke ola lawelawe o ka huahana. ʻO ke kahua o ka hoʻohana ʻana i ka papa PCB multi-layer ma ka ʻoihana ʻenehana kiʻekiʻe, e koi pono i ka papa i ke kūpaʻa kiʻekiʻe, ke kūpaʻa kemika kiʻekiʻe, a hiki ke kū i ka wela kiʻekiʻe, ka haʻahaʻa kiʻekiʻe a pēlā aku.

No laila, hoʻohana ka hana ʻana i nā papa PCB multi-layer ma ka liʻiliʻi loa o TG150 mau papa, i mea e hōʻoia ai e hoʻemi ʻia ka papa kaapuni e nā kumu o waho i ke kaʻina o ka noi a hoʻonui i ke ola lawelawe o ka huahana.

ʻO ke kolu, kiʻekiʻe TG plate type paʻa a me ka hilinaʻi kiʻekiʻe

He aha ka waiwai TG?

Waiwai TG: ʻO TG ka wela kiʻekiʻe loa e paʻa ai ka pepa, a ʻo ka waiwai TG e pili ana i ka mahana i hoʻololi ʻia ai ka polymer amorphous (me ka ʻāpana amorphous o ka polymer crystalline) mai ke kūlana aniani a i ke kūlana elastic kiʻekiʻe (rubber). mokuʻāina).

ʻO ka waiwai TG ka wela koʻikoʻi kahi e hoʻoheheʻe ai ka substrate mai ka paʻa a hiki i ka wai rubbery.

ʻO ke kiʻekiʻe o ka waiwai TG pili pono i ka paʻa a me ka hilinaʻi o nā huahana PCB, a ʻoi aku ka kiʻekiʻe o ka waiwai TG o ka papa, ʻoi aku ka ikaika o ka paʻa a me ka hilinaʻi.

Loaʻa i ka pepa TG kiʻekiʻe nā pono penei:

1) Ke kūpaʻa wela kiʻekiʻe, hiki ke hōʻemi i ka lana ʻana o nā pads PCB i ka wā hoʻoheheʻe wela infrared, hoʻoheheʻe a me ka haʻalulu wela.

2) Hiki ke hoʻemi ʻia ka hoʻonui ʻana o ka wela haʻahaʻa (CTE haʻahaʻa) i ka warping ma muli o nā kumu wela, a hoʻemi i ka haki keleawe ma ke kihi o ka lua i hoʻonui ʻia e ka hoʻonui wela, ʻoi aku hoʻi i nā papa PCB me ʻewalu a ʻoi aku paha nā papa, ka hana o ka plated ma nā lua. ʻoi aku ka maikaʻi ma mua o nā papa PCB me nā koina TG maʻamau.

3) Loaʻa i ke kūpaʻa kemika maikaʻi loa, i hiki ke hoʻomoʻi ʻia ka papa PCB i ke kaʻina hana hoʻomaʻamaʻa pulu a me nā hopena kemika he nui, paʻa mau kāna hana.
