I te wā e keri ana i te PCB miihini, me uru tonu te keri-iti kotahi ki roto i ngā rauemi maha, tae atu ki te pepa parahi, te kapia, te muka karāhe me ngā whakakī mahi. Ahakoa te āhua nei he keri auau noa iho te tukanga, ka pāngia tonutia ngā taha tapahi o te keri-iti e te kakahu whakakoi mai i ngā matūriki mārō, te wera waku me ngā kawenga miihini hurihuri.
I te whanaketanga tonu o te hanga PCB ki te kiato ara iahiko teitei ake, te maha o ngā paparanga me ngā āhuahanga pai ake, kei te iti haere te whānui o ngā kōhao kua keria. I taua wā, kei te whānui haere te whakamahinga o ngā paparanga uaua ki te mīhini, tae atu ki ngā rauemi Tg teitei me ngā rauemi whakakī nui. Ina koa ka heke te whānui o te keria moroiti ki raro iho i te 0.1 mm, ka nui ake ngā whakaritenga mō te kaha o te pito keria, te ātete ki te kakahu hou, te tango maramara me te pumau o te keria whānui.
Kia nui te pakaru, ka horapa te pānga ki tua atu i te roa o te ora o te taputapu. Tērā pea ka piki ake te taratara o te pakitara kōhao, ngā kōhao tomo me te puta, te iti o te matotoru o te kōhao, tae atu ki te pakaru o te keri.
Nō reira, ko te whakapai ake i te ātete ki te kakahu o ngā keri moroiti me te whakaiti i te waku mā roto i ngā paninga mata kei te noho hei huarahi hangarau nui hei whakarei ake i te kounga o te keri PCB.
1. He nui ake ngā pānga o te kakahu o te wiri iti i te roanga o te taputapu
Ko ngā paparanga PCB he mea hanga i te pepa parahi, te kapia, te muka karāhe me ngā momo whakakī mahi. I te wā e keri tere ana, me tapahi tonu te keri-iti i ngā rauemi he rerekē ngā āhuatanga miihini me te wera. Ko ngā muka karāhe me ētahi whakakī mārō ka puta tonu te pakaru o te pūwāhi keri me ngā taha tapahi, engari ka piri pea te kapia ki te pūwāhi keri, ki ngā putorino porowhita rānei i raro i ngā pānga o te waku me te wera tapahi, ka pā kino ki te tangohanga maramara i muri mai.
I te piki haere o te maha o ngā kōhao kua keria, ka pōturi haere ngā taha tapahi o te keri-iti. Ka piki ake te pana tuaka e hiahiatia ana hei uru ki te raima, ā, ka kaha ake te waku me te whakaputa wera. I raro i ēnei āhuatanga, ka heke haere te mahi tapahi i runga i te pepa parahi, te kapia me te muka karāhe, ka hua ake he pēhitanga, he waru, he haehae rānei, kaua ki te tango rauemi ma. Tērā pea ka piki ake te taratara o te pakitara kōhao, ka puta ake he kohao urunga me te putanga, ā, ka whakaiti i te ōritetanga o te whānui o te kōhao. Mō ngā PCB raina-pai me ngā papa hononga-kiato teitei, HDI rānei, ka piki ake pea te uaua o te whakarewa kōhao me te whakahaere kounga i muri mai i ēnei hapa.
Hei tāpiritanga, ko te iti o te diameter o te keri-iti, ko te iti ake o te kaha o ngā putorino porowhita ki te noho ki ngā maramara. Ina kohia ngā maramara, ina piri rānei te kapia ki te pūwāhi keri, ki ngā taha tapahi, ki ngā putorino maramara rānei, ka rerekē pea te ātete keri. Ina honoa ki te kakahu o te keri-iti, te oma o te porowhita, ngā tawhā keri kāore i te tika, ka piki ake pea ngā kawenga piko me te torsional e pā ana ki te keri-iti, ā, ka piki ake te mōrearea o te piko me te pakaru o te keri.
2. Me pēhea te whakapai ake a ngā paninga keri-iti i te keri PCB?
Ka taea te whakatakoto i ngā paninga mārō pēnei i te ta-C, AlTiN, AlCrN me te CrN ki runga i ngā keri-iti PCB. I roto i ēnei rauemi, ko te waro kore-āhua tetrahedral, te ta-C rānei, e whakakotahi ana i te mārō teitei me te tauwehenga waku iti, e āwhina ana ki te whakaiti i te kakahu mata hou me te ātete keri me te tiaki i te pūwāhi keri me ngā taha tapahi. I roto i ngā tono mahi, ka whakapai ake ngā paninga keri-iti i te mahi keri mā te whakaroa i te kakahu mata hou, te whakaiti i te ātete waku me te tango maramara, me te whakaū i te kounga o te kōhao.
Ka whakaitihia e ngā paninga pakeke-teitei te pa atu tika i waenga i ngā muka karāhe, ngā whakakī mārō me te papa sima-carbide. Ka āwhina tēnei i te puhoi o te pakaru o te pūwāhi keri, ngā taha tapahi tuatahi me ngā tawhā, ka taea ai e te keri-iti te pupuri i te āhua mata tapahi pumau i roto i te maha o ngā huringa keri.
Mā ngā paninga iti-waku ka āwhina i te whakaiti i te waku i waenga i te wiri-iti, te papa PCB me ngā maramara kua hangaia. Tērā pea ka whakaitihia te piri o ngā maramara me te kapia ki te pūwāhi wiri me ngā putorino porowhita, ka hangaia he āhua mata pai ake mō te tango maramara.
Ina whakahaeretia te tere o te pakaru o ngā mata tapahi, ka taea te whakaiti i ngā rerekētanga o te āhua o ngā mata tapahi i ngā wāhanga rerekē o te miihini. Ka āwhina tēnei ki te whakapai ake i te kounga o te pakitara kōhao me te ōritetanga o te whānui o te kōhao, me te whakawhāiti hoki i te hanganga o ngā kōhao tomo me te putanga.
Heoi, kāore e taea e ngā paninga te whakakore katoa i te pakaru o te wiri. E pā ana hoki te pakaru o te wiri ki te whānui o te wiri moroiti, te momo raima, te teitei o te puranga, te āhua o te porowhita me ngā tawhā keri. Mā te whakaroa i te kakahu, te whakaiti i te waku me te whakapai ake i te tango maramara, ka taea e te paninga kua hangaia tika te whakaiti i ngā kawenga tapahi rerekē, ā, nō reira ka whakaiti i te tūponotanga o te pakaru o te wiri.
3. Ko ngā Wiri-Iti Iti ake e hiahia ana ki ngā Tukanga Paninga Tika Ake
Ki te whakaritea ki ngā taputapu tapahi tuku iho, he iti ake ngā āhua o ngā keri-iti PCB, ā, he ātaahua ake ngā pito keri-iti me ngā āhua hou. Nō reira, kāore e taea e ngā paninga keri-iti te arotahi anake ki te whakatutuki i te pakeketanga teitei. Me āta tirotiro hoki te matotoru o te kiriata, te kounga o te mata me te piri o te paninga-papa.
Mena he angiangi rawa te paninga, kāore pea e ranea tōna parenga ki te kakahu whakakoi. Mena he matotoru rawa, ka rerekē pea te āhua moroiti o te mata tapahi, ā, ka porowhita, ka pōturi rānei te mata. Ko te iti o te diameter o te wiri moroiti, ka nui ake te aro o tana mahi tapahi ki te matotoru o te paninga.
Tērā pea ka puta ake ngā matūriki nui i te whakatakotoranga pewa katotika tuku iho. Mēnā ka whakatakotorangahia ēnei matūriki nui ki te taha o te pūwāhi keri, te mata tapahi, te taha rānei, ka piki ake pea te taratara o te mata paninga, ka whakararu hoki i te koi o te mata tapahi. Mō ngā keri moroiti tino pai me ngā diameter kei raro iho i te 0.1 mm, ka nui ake te pānga o ngā matūriki o te rahi tino rite ki te āhua tapahi.
Kei roto hoki i ngā keri-iti ngā āhuatanga matatini e toru-ahu, tae atu ki te pū keri, ngā taha tapahi, ngā tawhā me ngā putorino maramara porowhita. Nō reira, me arotau katoa te hoahoa o ngā taputapu, te kiato uta me te nekehanga o te papa kia eke ki te kapi paninga e tika ana mō ngā wāhi mahi rerekē, me te pupuri tonu i te ōritetanga i waenga i ngā keri-iti takitahi.
