Pepa parahiHe iti te tere o te hāora o te mata, ā, ka taea te tāpiri ki ngā momo papa rerekē, pērā i te konganuku, ngā rauemi whakamahana. Ā, ko te pepa parahi te nuinga o te wā e whakamahia ana hei parepare hikohiko me te ārai-patū. Hei whakanoho i te pepa parahi kawe ki runga i te mata o te papa, me te whakakotahi ki te papa whakarewa, ka whakaratohia he pai te haere tonu me te parepare hikohiko. Ka taea te wehewehe ki: te pepa parahi piri-ake, te pepa parahi taha kotahi, te pepa parahi taha rua me ērā atu.

I tēnei kōrero, ki te mea kei te hiahia koe ki te ako atu mō te pepa parahi i roto i te tukanga hanga PCB, tirohia, pānuihia hoki ngā kōrero kei raro nei mō ētahi atu mōhiotanga ngaio.

He aha ngā āhuatanga o te pepa parahi i roto i te hanga PCB?

Pepa parahi PCBKo te matotoru parahi tuatahi e whakamahia ana ki ngā paparanga o waho, o roto hoki o tētahi paparanga PCB maha-apa. Ko te taumaha parahi e tautuhia ana ko te taumaha (i roto i ngā auneke) o te parahi kei roto i te kotahi putu tapawha o te horahanga. E tohu ana tēnei tawhā i te matotoru katoa o te parahi i runga i te paparanga. Ka whakamahia e MADPCB ngā taumaha parahi e whai ake nei mō te hanga PCB (pre-plate). Ngā taumaha e inehia ana i roto i te auneke/putu2. Ka taea te whiriwhiri i te taumaha parahi e tika ana kia uru ki te whakaritenga hoahoa.

· I roto i te hanga PCB, ko ngā pepa parahi he rōra, he karaehe hiko me te parakore o te 99.7%, me te matotoru o te 1/3oz/ft2 (12μm, 0.47mil rānei) – 2oz/ft2 (70μm, 2.8mil rānei).

· He iti ake te tere o te hāora o te mata o te pepa parahi, ā, ka taea e ngā kaihanga paparanga te tāpiri i mua ki ngā rauemi turanga, pērā i te matua whakarewa, te polyimide, te FR-4, te PTFE me te uku, hei hanga paparanga kua whakakikoruatia ki te parahi.

· Ka taea hoki te whakauru ki roto i tētahi papa paparanga maha hei pepa konukōre parahi i mua i te pēhi.

· I roto i te hanga PCB tuku iho, ko te matotoru parahi whakamutunga o ngā paparanga o roto ka toe tonu mai i te pepa parahi tuatahi; I ngā paparanga o waho ka peretihia e mātou he parahi 18-30μm tāpiri ki runga i ngā ara i te wā e peretihia ana te panera.

· Ko te parahi mō ngā paparanga o waho o ngā papa paparanga maha he rite ki te pepa parahi, ā, ka pēhia ngātahitia ki ngā prepregs, ki ngā matua rānei. Mō te whakamahi me ngā microvias i roto i te HDI PCB, kei runga tika te pepa parahi i te RCC (te parahi pania ki te kapia).

He aha te take e hiahiatia ai te pepa parahi i roto i te hanga PCB?

Ko te pepa parahi hiko (neke atu i te 99.7% te parakore, 5um-105um te matotoru) tētahi o ngā rauemi taketake o te umanga hikohiko. Kei te tere te whanaketanga o te umanga mōhiohio hikohiko, ā, kei te tipu haere te whakamahinga o te pepa parahi hikohiko, ā, he whānuitia te whakamahinga o ngā hua i roto i ngā tātaitai ahumahi, ngā taputapu whakawhitiwhiti kōrero, ngā taputapu QA, ngā pākahiko lithium-ion, ngā pouaka whakaata ā-iwi, ngā taputapu hopu ataata, ngā kaitākaro CD, ngā mīhini tārua, ngā waea, ngā hauhautanga, ngā hikohiko motuka, me ngā papatohu kēmu.

Pepa parahi ahumahiKa taea te wehewehe kia rua ngā wāhanga: te pepa parahi hurihuri (pepa parahi RA) me te pepa parahi pūwāhi (pepa parahi ED), he pai te ngāwari o te pepa parahi maramataka me ētahi atu āhuatanga, ko te pepa parahi ngohengohe te tukanga tuatahi i whakamahia, ko te pepa parahi hiko te mea iti ake te utu o te hanga pepa parahi. I te mea he rauemi mata nui te pepa parahi hurihuri mō te papa ngohengohe, he pānga anō hoki ngā āhuatanga o te pepa parahi maramataka me ngā huringa utu i runga i te umanga papa ngohengohe.

He aha ngā ture hoahoa taketake mō te pepa parahi i roto i te PCB?

E mōhio ana koe he mea tino noa te whakamahi i ngā papa hiko tā? E tino mōhio ana ahau kei roto i te taputapu hiko e whakamahia ana e koe i tēnei wā tētahi. Heoi, he mahi noa anō hoki te whakamahi i ēnei taputapu hiko me te kore e mārama ki tā rātou hangarau me te tikanga hoahoa. Kei te whakamahi te tangata i ngā taputapu hiko i ia hāora engari kāore rātou e mōhio ki tā rātou mahi. Nō reira, anei ētahi wāhanga matua o te PCB kua whakahuatia hei āwhina i a koe ki te mārama tere ki te mahi a ngā papa hiko tā.

· He papa kirihou noa iho te papa hiko tā, he karāhe anō hoki te tāpiri. Ka whakamahia te pepa parahi hei whai i ngā ara, ā, ka taea te rere o ngā utu me ngā tohu i roto i te taputapu. Ko ngā tohu parahi te huarahi hei whakarato hiko ki ngā wāhanga rerekē o te taputapu hiko. Engari ko ngā tohu parahi te arataki i te rere o ngā utu i roto i ngā PCB, ko ngā tohu parahi te mea hei utu mō ngā waea hiko.

· Ka taea te whakamahi i ngā PCB hei paparanga kotahi, hei paparanga rua hoki. Ko ngā PCB paparanga kotahi ngā mea māmā. He pepa parahi kei tētahi taha, ā, ko tētahi taha te wāhi mō ngā wāhanga kē atu. Mō te PCB paparanga-rua, e rua ngā taha e rāhuitia ana mō te pepa parahi. Ko ngā PCB paparanga-rua ngā PCB uaua he tohu uaua mō te rere o ngā utu. Kāore he pepa parahi e whiti tetahi ki tetahi. E hiahiatia ana ēnei PCB mō ngā taputapu hiko taumaha.

· E rua ngā paparanga o ngā tūhono me te mata hiraka i runga i te PCB parahi. Ka whakamahia he kopare tūhono hei wehewehe i te tae o te PCB. He maha ngā tae o ngā PCB e wātea ana pērā i te kakariki, te papura, te whero, me ētahi atu. Ka tohua hoki e te kopare tūhono te parahi mai i ētahi atu konganuku hei mārama i te uauatanga o te hononga. Ahakoa ko te mata hiraka te wāhanga tuhinga o te PCB, ka tuhia ngā reta me ngā tau rerekē ki runga i te mata hiraka mō te kaiwhakamahi me te miihini.

Me pēhea te whiriwhiri i te rauemi tika mō te pepa parahi i roto i te PCB?

E ai ki te kōrero i mua ake nei, me mātaki koe i te huarahi taahiraa-i-te-taahiraa hei mārama ki te tauira hanga o te papa hiko tā. He rerekē ngā paparanga o te hanganga o ēnei papa. Kia mārama tātou ki tēnei mā te raupapa:

Rauemi papa:

Ko te turanga matua i runga i te papa kirihou e whakamahia ana te karāhe ko te papa. Ko te papa he hanganga hiko-kore o te rau e hangaia ana i te nuinga o te wā mai i ngā kapia epoxy me te pepa karāhe. Kua hangaia te papa kia tutuki ai ngā whakaritenga, pērā i te pāmahana whakawhiti (TG).

Whakarārangi:

E mārama ana i te ingoa, he huarahi anō hoki te whakarārangi hei whiwhi i ngā āhuatanga e hiahiatia ana pērā i te whakawhānui wera, te kaha kutikuti, me te wera whakawhiti (TG). Ka mahia te whakarārangi i raro i te pēhanga teitei. He mea nui te whakarārangi me te papa i roto i te rere o ngā utu hiko i roto i te PCB.
