ENIG Pahu-nui   FR4 PCB Hoʻolauna

--Wehewehe

ʻO FR ke ʻano o ka "pale-ahi," ʻo FR-4 (a i ʻole FR4) kahi papa inoa NEMA no nā mea laminate epoxy i hoʻoikaika ʻia i ke aniani, kahi mea i haku ʻia me i ulana lole fiberglass me ka epoxy resin binder ʻo ia ka substrate kūpono no nā mea uila ma ka papa kaapuni paʻi.

- ʻO nā pono a me nā pōʻino o FR4 PCB

• He mea kaulana loa ka mea FR-4 ma muli o kona mau ʻano maikaʻi e hiki ai ke pōmaikaʻi i nā papa kaapuni paʻi.Ma waho aʻe o ke kumukūʻai a me ka maʻalahi o ka hana ʻana, he insulator uila me ka ikaika dielectric kiʻekiʻe loa.Eia hou, ʻo ia paʻa, kūpaʻa i ka maʻu, kūpaʻa wela a māmā.

• ʻO FR-4 kahi mea pili ākea, kaulana loa no kona kumu kūʻai haʻahaʻa a me ka paʻa ʻana o ka mīkini a me ka uila.ʻOiai e loaʻa ana kēia mea waiwai i nā pōmaikaʻi nui a loaʻa i nā ʻano mānoanoa a me nā nui, ʻaʻole ia ke koho maikaʻi loa no kēlā me kēia noi, ʻoi aku ka nui o nā noi kiʻekiʻe e like me RF a me nā hoʻolālā microwave.

- Hoʻolālā PCB papa nui

Hoʻonui hou ka Multilayer PCB i ka paʻakikī a me ka nui o nā hoʻolālā PCB ma o ka hoʻohui ʻana i nā papa ʻē aʻe ma mua o nā papa luna a me lalo i ʻike ʻia i nā papa ʻaoʻao ʻelua. Kūkulu ʻia nā PCB multilayer e ka laminating i nā papa like ʻole.ʻO ka ʻO nā papa i loko, nā papa kaapuni ʻaoʻao ʻelua maʻamau, hoʻopaʻa pū ʻia, me nā papa insulating ma waena a ma waena o ke keleawe-foil no nā papa-waho.ʻO nā puka i wili ʻia ma ka papa (vias) e hoʻopili ai me nā papa like ʻole o ka papa.

ʻO nā mea maikaʻi a me nā pōʻino o Ka Immersion Nickel Uila ʻole (ENIG)

E ʻO NIG ka he ʻāpana metala ʻelua, me ka nickel e hana ana ma ke ʻano he pale i ke keleawe a me ka ʻili kahi i kūʻai ʻia ai nā ʻāpana.Mālama kahi papa gula i ka nickel i ka wā e mālama ai.

Pono:

• Nā ʻili palahalaha
• Ikaika
• Ke alakaʻi ʻole
• Maikaʻi no PTH

Cons:

• ʻO ka maʻi ʻeleʻele
• Pipiʻi
• ʻAʻole maikaʻi no ka hana hou

No hea mai ka mea resin ma ABIS?

ʻO ka hapa nui o lākou mai Shengyi Technology Co., Ltd. (SYTECH), ʻo ia ka lua o ka mea hana CCL nui loa o ka honua e pili ana i ka nui o ke kūʻai aku, mai 2013 a 2017. Ua hoʻokumu mākou i nā pilina lōʻihi o ka launa pū ʻana. mai 2006. ʻO ka mea resin FR4 ( Hoʻohālike S1000-2, S1141, S1165, S1600 ) hoʻohana nui ʻia no ka hana ʻana i nā papa kaapuni paʻi hoʻokahi a me nā ʻaoʻao ʻelua a me nā papa multi-layer.Eia nā kikoʻī no kāu kuhikuhi.

• No FR-4: Sheng Yi, King Board, Nan Ya, Polycard, ITEQ, ISOLA

• No CEM-1 & CEM 3: Sheng Yi, Papa Alii

• No ke alapine kiʻekiʻe: Sheng Yi

• No ka ho'ōla UV: Tamura, Chang Xing ( * Loaʻa kala: ʻOmaomao) Solder no ka ʻaoʻao hoʻokahi

• No ke kiʻi wai wai: Tao Yang, pale (kiʻiʻoniʻoni wet)

• Chuan Yu ( * Loaʻa nā kala: Keʻokeʻo, Imaginable Solder Yellow, Purple, Red, Blue, Green, Black)

ʻOi aku ka mana hana PCB

Ua ʻike ʻo ABIS i ka hana ʻana i nā mea kūikawā no ka PCB paʻa, e like me: CEM-1/CEM-3, PI, Tg Kiʻekiʻe, Rogers, PTEF, Alu/Cu Base , etc. Aia ma lalo iho kahi ʻike pōkole FYI.

Ke Kaʻina Hana Hana PCB-nui

• Hoʻomaka ke kaʻina hana me ka hoʻolālā ʻana i ka Layout o ka PCB me ka hoʻohana ʻana i kekahi polokalamu hoʻolālā PCB / CAD Tool ( Proteus, Eagle, a i ʻole CAD ).

• ʻO ke koena o nā ʻanuʻu o ka Hana Hana ʻana o kahi Papa Kaapuni Paʻi Paʻi ʻia e like me ka PCB ʻaoʻao hoʻokahi a i ʻole PCB ʻaoʻao ʻelua a i ʻole PCB multi-layer.

ʻO ka PCB papa-nui Ka manawa o waena o ka hoʻomaka a i ka wā pau

- Hoomakaukau Puka

Ke wehe pono nei i ka ʻōpala a me ka hoʻoponopono ʻana i nā ʻāpana mīkini drill: ma mua o ka hoʻopaʻa ʻia ʻana me ke keleawe, e nānā nui ka abis i nā puka āpau ma kahi fr4 pcb i mālama ʻia e wehe i nā ʻōpala, nā hewa ʻole o ka ʻili, a me ka epoxy smear. .no hoi, i ka hoomaka ana o ke kaʻina hana, drill machine parameter ua hoʻoponopono pololei.

- S Ka hoʻomākaukau ʻana o ka urface

Hoʻopau me ke akahele: e ʻike mua kā mākou poʻe ʻenehana loea ʻo ke ala wale nō e pale aku ai i kahi hopena maikaʻi ʻole ʻo ka manaʻo ʻana i ka pono o ka lawelawe kūikawā a me ka hana ʻana i nā hana kūpono e hōʻoia i ka hana pono a me ka pololei.

- Ua ʻōlelo ʻo T Nā Uku Hoʻonui Hermal

Maʻa i ka hana ʻana i nā mea like ʻole, hiki i ka abis ke nānā i ka hui ʻana e hōʻoia i ke kūpono.a laila mālama i ka hilinaʻi lōʻihi o ka cte (coefficient of thermal expansion), me ka cte haʻahaʻa, ʻoi aku ka liʻiliʻi o ka pale ʻana i nā lua mai ka hoʻololi pinepine ʻana o ke keleawe e hoʻopili ai i nā pilina o loko.

- Ka hoʻonui ʻana

Hoʻonui ʻia ka mana ʻo Abis i ka circuitry e nā pākēneka i ʻike ʻia i ka kali ʻana i kēia nalowale i hiki ai i nā papa ke hoʻi i ko lākou mau ana i hoʻolālā ʻia ma hope o ka pau ʻana o ka pōʻai lamination.no hoi, ka hoʻohana 'ana i ka baseline scaling paipai 'ana i ka hui 'ana me i loko o ka hale helu kaʻina hana hoʻomalu 'ikepili, e dial-i ka unahiʻole mea e e kūlike i ka manawa i loko o kēlā wahi manufacturing.

 

- Mīkini

Ke hiki mai ka manawa e kūkulu ai i kāu pcb, e ʻike pono ʻoe e koho i nā lako kūpono a me ka ʻike e hana pono ai i ka hoʻāʻo mua.

Puke a me ka lawe ʻana

ʻAʻole hoʻāʻo wale ʻo ABIS CIRCUITS Company e hāʻawi i nā mea kūʻai aku i kahi huahana maikaʻi, akā e hoʻolohe pū i ka hāʻawi ʻana i kahi pūʻolo piha a palekana.Eia kekahi, hoʻomākaukau mākou i kekahi mau lawelawe pilikino no nā kauoha āpau.
