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, he ʻano o ka hoʻohana ʻana i nā mea insulating ma ke ʻano he substrate, e like me: polyimide a i ʻole polyester film, a laila ma o kahi kaʻina hana kūikawā i hana ʻia i ka papa kaapuni paʻi. 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 paʻa, ʻoihana kamepiula, ʻoihana TV, ʻoihana kiʻi kiʻi kiʻi kiʻi a me nā mea liʻiliʻi liʻiliʻi.

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.

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.

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 (moʻa 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 ka elasticity kiʻekiʻe, ʻano like ʻole 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 ka mākeke, ʻoi aku ka kiʻekiʻe o ka mākeke e pili ana i ka maikaʻi o ka papa, a ke piʻi mau nei ka makemake o ka mea kūʻai aku no nā papa kaapuni TG kiʻekiʻe.

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 (ke aupuni Ruber).

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 thermal expansion, ʻoi aku hoʻi i nā papa PCB me ʻewalu a ʻoi aku paha nā papa, ʻoi aku ka maikaʻi o ka hana ʻana o ka plated ma nā lua 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.
