HONONGA WAEA

PUKA MŌ TE PŪTAKE MĀTAURANGA

He aha te Here Waea?

Ko te here waea te tikanga e herea ai he waea konganuku ngohengohe iti te diameter ki tētahi mata konganuku hototahi, me te kore e whakamahia he tūhono, he rere, ā, i ētahi wā me te whakamahi i te wera neke atu i te 150 nekehanga Celsius. Ko ngā konganuku ngohengohe ko te Koura (Au), te Parahi (Cu), te Hiriwa (Ag), te Konumohe (Al) me ngā koranu pērā i te Palladium-Silver (PdAg) me ētahi atu.

Te Mārama ki ngā Tikanga me ngā Tukanga Here Waea mō ngā Whakamahinga Huinga Hikohiko Moroiti.
Ngā Tikanga/Tukanga Herenga Wedge: Rīpene, Pōro Thermonic me te Herenga Wedge Ultrasonic
Ko te here waea te tikanga hanga hononga i waenga i tētahi ara iahiko whakauru (IC) me tētahi taputapu haurua-ā-ira rite rānei me tōna kete, anga ārahi rānei i te wā e hangaia ana. E whakamahia whānuitia ana hoki i ēnei rā hei whakarato hononga hiko i roto i ngā huihuinga pākahiko Lithium-ion. Ko te here waea te mea e kiia ana ko te mea tino utu nui me te ngāwari o ngā hangarau hononga hiko iti e wātea ana, ā, e whakamahia ana i roto i te nuinga o ngā kete haurua-ā-ira e hangaia ana i ēnei rā. He maha ngā tikanga here waea, arā: Te Here Waea Thermo-Compression:
Ko te here waea pēhanga-wera (te whakakotahi ki ngā mata pea (te nuinga o te Au) i raro i te kaha kume me ngā pāmahana atanga teitei, he nui ake i te 300°C, hei whakaputa i te whakarewa), i whakawhanakehia tuatahitia i ngā tau 1950 mō ngā hononga hikohiko iti, heoi i tere te whakakapia e te here Ultrasonic me te Thermsonic i ngā tau 1960 hei hangarau hononga matua. Kei te whakamahia tonu te here pēhanga-wera mō ngā tono motuhake i ēnei rā, engari i te nuinga o te wā ka karohia e ngā kaihanga nā te mea he teitei ngā pāmahana atanga (he maha ngā wā ka kino) e hiahiatia ana hei hanga i tētahi hononga angitu. Here Waea Wedge Ultrasonic:
I ngā tau 1960, ko te hononga waea poro Ultrasonic te tikanga matua mō te hononga. Mā te whakamahi i te wiri auau teitei (mā te transducer e whakaoho ana) ki te taputapu hononga me te kaha piri kotahi, ka taea te whakarewa i ngā waea Konumohe me te Koura i te pāmahana rūma. Ka āwhina tēnei wiri Ultrasonic ki te tango i ngā poke (ngā waikura, ngā poke, me ētahi atu) mai i ngā mata hononga i te tīmatanga o te huringa hononga, me te whakatairanga i te tipu intermetallic hei whakawhanake me te whakapakari i te hononga. Ko ngā auau noa mō te hononga ko te 60 – 120 KHz. E rua ngā hangarau tukanga matua o te tikanga poro ultrasonic: Te hononga waea nui (taumaha) mō ngā waea >100µm te whānui Te hononga waea pai (iti) mō ngā waea <75µm te whānui Ka kitea ngā tauira o ngā huringa hononga Ultrasonic noa i konei mō te waea pai me konei mō te waea nui. Ka whakamahia e te hononga waea poro Ultrasonic he taputapu hononga motuhake, he "poro" rānei, he mea hanga mai i te Tungsten Carbide (mō te waea Konumohe) Titanium Carbide rānei (mō te waea Koura) i runga i ngā whakaritenga tukanga me ngā diameter waea; Kei te wātea hoki ngā poro poro uku mō ngā whakamahinga motuhake. Te Herenga Waea Thermosonic:
Mēnā e hiahiatia ana he whakamahana tāpiri (ko te tikanga mō te waea koura, me ngā atanga hononga i te awhe 100 – 250°C), ka kiia te tukanga ko te hononga waea Thermosonic. He nui ngā painga o tēnei i te pūnaha thermo-compression tuku iho, nā te mea he iti ake ngā pāmahana atanga e hiahiatia ana (kua whakahuatia te hononga Au i te pāmahana rūma engari i roto i te mahi kāore e pono me te kore he wera tāpiri). Te Hononga Pōro Thermosonic:
Ko tētahi atu momo hononga waea Thermsonic ko te Ball Bonding (tirohia te huringa hononga pōro i konei). Ka whakamahia e tēnei tikanga he taputapu hononga capillary uku i runga ake i ngā hoahoa wedge tuku iho hei whakakotahi i ngā āhuatanga pai rawa atu i roto i te hononga thermo-compression me te ultrasonic me te kore he ngoikoretanga. Mā te wiri thermosonic ka noho iti te pāmahana o te atanga, ko te hononga tuatahi, ko te hononga pōro kua kōpekehia te wera ka taea te whakanoho i te waea me te hononga tuarua ki tētahi ahunga, kaua ki te rārangi ki te hononga tuatahi, he herenga tēnei i roto i te hononga waea Ultrasonic. Mō te hanga aunoa, nui te rahinga, he tere ake ngā hononga pōro i ngā hononga Ultrasonic / Thermsonic (Wedge), ka waiho te hononga pōro Thermsonic hei hangarau hononga matua i roto i te microelectronics mō ngā tau 50+ kua hipa. Hononga Rīpene:
Ko te here rīpene, mā te whakamahi i ngā rīpene konganuku papatahi, kua roa e whakamahia ana i roto i ngā hikohiko RF me te ngaruiti mō ngā tekau tau (he pai ake te ngaronga o te tohu mā te rīpene [pānga kiri] ki te waea porowhita tuku iho). Ko ngā rīpene koura iti, tae atu ki te 75µm te whānui me te 25µm te matotoru, ka herea mā te tukanga Thermsonic me te taputapu here porowhita mata-papatahi nui. Ka taea hoki te here i ngā rīpene konumohe tae atu ki te 2,000µm te whānui me te 250µm te matotoru me te tukanga porowhita Ultrasonic, nā te mea kua piki ake te hiahia mō ngā hononga porowhita iti, kiato teitei.

He aha te waea here koura?

Ko te here waea koura te tukanga e herea ai te waea koura ki ngā pūwāhi e rua i roto i te huihuinga hei hanga hononga, hei ara kawe hiko rānei. Ka whakamahia te wera, te ultrasonic, me te kaha hei hanga i ngā pūwāhi whakapiri mō te waea koura. Ka tīmata te tukanga hanga i te pūwāhi whakapiri mā te hanganga o te pōro koura i te pito o te taputapu here waea, te capillary. Ka pēhia tēnei pōro ki runga i te mata huihuinga wera me te whakamahi i te nui o te kaha motuhake me te auau o te 60kHz - 152kHz o te nekehanga ultrasonic me te taputapu. Kia oti te hononga tuatahi, ka whakahaerehia te waea i roto i te huarahi tino whakahaere kia hanga te āhua koropiko e tika ana mō te āhua o te huihuinga. Ko te hononga tuarua, e kiia ana ko te tuitui, ka hangaia ki runga i tetahi atu mata mā te pēhi ki raro ki te waea me te whakamahi i te rawhi hei haehae i te waea i te hononga.

Mā te herea waea koura ka taea te hono i roto i ngā takai he tino kawe hiko, tata ki te nui ake i ētahi whakarewa. Hei tāpiri, he nui ake te ātete o ngā waea koura ki te waikura ki ērā atu rauemi waea, ā, he ngawari ake i te nuinga, he mea nui tēnei mō ngā mata tairongo.
Ka rerekē pea te tukanga i runga i ngā hiahia o te huihuinga. Mō ngā rauemi tairongo, ka taea te whakatakoto i tētahi pōro koura ki te wāhi hononga tuarua hei hanga i tētahi hononga kaha ake, me tētahi hononga "ngawari ake" hei ārai i te kino o te mata o te wāhanga. Mō ngā āputa kuiti, ka taea te whakamahi i tētahi pōro kotahi hei tīmatanga mō ngā hononga e rua, ka hanga he hononga āhua "V". Ina hiahia kia pakari ake te hononga waea, ka taea te whakatakoto i tētahi pōro ki runga i tētahi tuitui hei hanga i tētahi hononga haumaru, ka whakanui ake i te pumau me te kaha o te waea. He tata kore mutunga ngā tono me ngā rerekētanga maha ki te hononga waea, ā, ka taea te whakatutuki mā te whakamahi i te pūmanawa aunoa i runga i ngā pūnaha hononga waea a Palomar.
