He aha te rerekētanga i waenganui i te AOI me te SPI20240904?
Te Mārama ki te Tirotiro SPI: He Kī ki te Hanganga Hiko Pono
I roto i te ao hanga hikohiko, he mea nui te tika me te pono. Kua hurihia e te Hangarau Maunga Mata (SMT) te umanga, ka taea ai te hanga i ngā taputapu hikohiko kiato me te tino whai hua. Heoi, i te mea kua piki haere te uaua o ngā ara iahiko me ngā wāhanga, kua uaua ake te whakarite i te kounga me te mahi o ēnei huihuinga hikohiko. Koinei te wāhi e whai wāhi mai ai te Tirotiro Whakapiri Konukō (SPI). Ko te tirotiro SPI he tukanga whakahaere kounga nui i roto i te SMT e āwhina ana ki te pupuri i ngā paerewa teitei i roto i te hanga hikohiko. I roto i tēnei tuhinga, ka rukuhia e mātou ngā taipitopito oTirotiro SPI, tōna hiranga, ngā tikanga mahi, me tōna pānga ki te kounga whānui o ngā huihuinga hiko.
He aha te tirotiro SPI?
Ko te Tirotiro Whakapiri Whakarewa (SPI) e pā ana ki te tukanga aromatawai i te whakamahinga o te whakapiri whakarewa ki runga i te papa ara iahiko tā (PCB) i mua i te whakatakotoranga o ngā wāhanga hiko. Ko te whakapiri whakarewa he ranunga o te rerenga whakarewa me te paura whakarewa e whakamahia ana hei hanga hononga whakarewa i waenga i ngā wāhanga hiko me te PCB. He mea nui te whakamahinga tika o te whakapiri whakarewa nā te mea ka pā ki te pono me te mahi o te hua whakamutunga. Mā te SPI ka whakarite kia tika te whakamahinga o te whakapiri whakarewa, i te rahinga tika, me ngā wāhi tika, ka whakaiti i te tūponotanga o ngā hapa i te huihuinga whakamutunga.
He aha i whakamahia ai te tirotiro SPI i roto i te hanga hikohiko?
1. Te Ārai i ngā Hapa: He mea nui te mahi a te SPI ki te ārai i ngā hapa noa pēnei i ngā piriti honohono, te koretake o te honohono, me te kore e tika te tūnga o ngā wāhanga. Mā te kite wawe i ēnei take i roto i te tukanga hanga, ka āwhina te SPI ki te karo i te utu nui o te mahi anō me te whakatika.
2. Whakapai Ake i te Pono: He mea nui te paninga tika o te whakapiri whakarewa hei hanga hononga whakarewa pono e tu atu ana i te ahotea miihini me ngā huringa wera. Ka whakarite te SPI kia ōrite te paninga o te whakapiri whakarewa, kia tika hoki, kia pai ake ai te pono me te roa o te wā e whakamahia ana te taputapu hiko.
3. Te Whai Hua o te Utu: He pai ake te kimi me te whakatika i ngā raruraru o te whakapiri whakarewa i ngā wāhanga tōmua o te hanga i te whakatika i ngā raruraru i muri i te whakatakotoranga, te whakarewa rānei i ngā wāhanga. Ka āwhina te SPI ki te whakaiti i te wā kore mahi whakaputa me te whakaiti i te para rauemi.
4. Te Whakatutuki i ngā Paerewa: He maha ngā ahumahi e hiahia ana kia piri ki ngā paerewa kounga me ngā ture motuhake. Ka āwhina te SPI i ngā kaihanga kia tutuki i ēnei paerewa mā te whakarite kia tutuki i te tono whakapiri whakarewa ngā whakaritenga e tika ana.
He aha ngā tikanga tirotiro SPI?
Ka taea te whakahaere i te SPI mā te whakamahi i ngā tikanga maha, he rerekē ngā painga me ngā whakamahinga o ia tikanga. Ko ngā tikanga matua ko:
1.Tirotiro Whatu Aunoa (AOI)Koinei te tikanga SPI tino noa, e whakamahi ana i ngā kāmera taumira teitei me ngā rauropi tukatuka whakaahua hei tirotiro i te tono whakapiri whakarewa. Ka taea e ngā pūnaha AOI te kite i ngā hapa pēnei i te nui rawa, te kore rānei o te whakapiri whakarewa, te he o te tūnga, me te hononga. He tino whai hua ēnei pūnaha, ā, ka taea te tukatuka tere i te nui o ngā PCB.
2.Tirotiro X-rayKa whakamahia te tirotiro hihi-X hei kimi i ngā take kāore e kitea e te kanohi tahanga, mā roto rānei i ngā tikanga whatu paerewa. He tino whai hua mō te tirotiro i ngā hanganga o roto o ngā PCB paparanga-maha, me te kimi i ngā take pēnei i ngā piriti honohono huna, ngā āputa rānei.
3. Tirotiro ā-Ringa: Ahakoa kāore i te tino kitea i roto i ngā mahi hanga nui, ka taea te whakamahi i te tirotiro ā-ringa i roto i ngā mahi hanga iti, hei tikanga tāpiri rānei. Ka tirotirohia e ngā kaitirotiro whai mātauranga te paninga whakapiri whakarewa, ā, ka whakamahia ngā taputapu pēnei i ngā karu whakanui hei tautuhi i ngā hapa.
4. Tirotiro Taiaho: Ka whakamahia e ngā pūnaha SPI e hangai ana ki te taiaho ngā taiaho hei ine i te teitei me te rōrahi o ngā putunga whakapiri whakarewa. Mā tēnei tikanga ka taea te ine tika, ā, he whai hua hoki ki te kite i ngā take e pā ana ki te rōrahi me te ōritetanga o te whakapiri.
He aha ngā tawhā matua i roto i te Tirotiro SPI?
He maha ngā tawhā matua ka arotakehia i te wā tirotiro SPI hei whakarite kia tika te paninga o te whakapiri whakarewa. Kei roto i ēnei tawhā:
1. Te Rōrahi o te Whakapiri Hononga: Me noho te nui o te whakapiri honohono i whakatakotoria ki ia papa i roto i ngā rohe kua tohua. Ki te nui rawa, ki te iti rawa rānei te whakapiri, ka raru pea ngā hononga honohono.
2. Matotoru o te Whakapiri: Me ōrite te matotoru o te paparanga whakapiri honohono kia tika ai te mākū me te piri o ngā wāhanga. Ka pāngia te kounga o te hononga honohono e ngā rerekētanga o te matotoru o te whakapiri.
3. Whakaritenga: Me whakarite tika te whakapiri honohono ki ngā papa PCB. Ki te hē te whakarite, ka ngoikore te hanganga o te hononga honohono, ā, ka raru pea te whakatakotoranga o ngā wāhanga.
4. Te Tohatoha o te Whakapiri: He mea nui te tohatoha ōrite o te whakapiri whakapiri puta noa i te PCB kia rite ai te whakapiri. Ka aromatawaihia e ngā pūnaha SPI te ōritetanga o te tohatoha whakapiri hei ārai i ngā take pēnei i te korenga o te whakapiri whakapiri, te hononga rānei.
Me pēhea te whakamana i te kounga o te tānga whakapiri whakarewa?
● Tere o te WhakamātautauKo te tere o te pēhi e whakatau ana i te roa o te wā e wātea ana mō te whakapiri honohono kia "hurihuri" ki roto i ngā pūaha o te tauira me runga i ngā papa o te PCB. Ko te tikanga, he 25mm ia hekona te tautuhinga e whakamahia ana engari he rerekē tēnei i runga i te rahi o ngā pūaha i roto i te tauira me te whakapiri honohono i whakamahia.
● Te Pēhanga o te KaitātariI te wā tānga, he mea nui kia pēhia te roanga o te mata pēhi kia horoia ai te tauira. Mēnā he iti rawa te pēhanga, ka "pani" te whakapiri ki te tauira, ka kore e pai te whakatakoto, ā, ka kore e taea te whakawhiti ki te PCB. Mēnā he nui rawa te pēhanga, ka "kohia" te whakapiri mai i ngā kōhao nui ake, ka nui rawa te pakaru o te tauira me ngā mīhini horoi, ā, ka "toto" te whakapiri i waenganui i te tauira me te PCB. Ko te tautuhinga noa mō te pēhanga mīhini horoi he 500 karamu te pēhanga mō ia 25mm o te mata mīhini horoi.
● Koki PēhiKo te koki o te squeegee e whakatakotoria ana ki te 60° e ngā kaipupuri e mau ana. Mēnā ka whakanuia te koki, ka "koko" pea te whakapiri o te kaipupuri mai i ngā kōhao o te tauira, ā, ka iti ake te whakapiri honohono e whakatakotoria ana. Mēnā ka whakaitihia te koki, ka waiho pea he toenga whakapiri honohono ki runga i te tauira i muri i te tānga o te pēhi.
● Tere Wehenga o te TāngaKoinei te tere o te wehenga o te PCB mai i te tauira i muri i te tānga. Me whakamahi he tautuhinga tere tae atu ki te 3mm ia hekona, ā, ka whakahaerea e te rahi o ngā kōhao i roto i te tauira. Ki te tere rawa tēnei, ka kore e tino tukuna te whakapiri whakarewa mai i ngā kōhao, ā, ka puta he taha teitei huri noa i ngā putunga, e mōhiotia ana ko ngā "taringa-kuri".
● Te Horoi i te TāngaMe horoi tonu te tauira i te wā e whakamahia ana, ā, ka taea te mahi ā-ringa, ā-aunoa rānei. He pūnaha tō te mīhini tā aunoa ka taea te whakarite kia horoia te tauira i muri i te maha o ngā tānga kua whakaritea mā te whakamahi i te rauemi kore-miro kua pania ki te matū horoi pērā i te Isopropyl Alcohol (IPA). E rua ngā mahi a te pūnaha, ko te tuatahi ko te horoi i te taha raro o te tauira hei aukati i te paru, ā, ko te tuarua ko te horoi i ngā kōhao mā te whakamahi i te korehau hei aukati i ngā aukati.
● Āhua o te Stencil me te SqueegeeMe ata penapena me te tiaki i ngā tauira me ngā tauira squeegee, nā te mea ka puta he hua kino mēnā ka pā mai he kino ki tētahi o ēnei. Me tirotirohia ngā mea e rua i mua i te whakamahinga, ā, me horoi pai i muri i te whakamahinga, ko te mea pai ko te whakamahi i tētahi pūnaha horoi aunoa kia tangohia ai ngā toenga whakapiri whakarewa. Mēnā ka kitea he kino ki te squeegee, ki ngā tauira rānei, me whakakapi kia tika ai te tukanga, kia taea ai te mahi anō.
● Tānga TāngaKoinei te tawhiti e haerehia ana e te squeegee puta noa i te tauira, ā, e taunakihia ana kia 20mm te iti rawa i tua atu i te kōhao tawhiti rawa. He mea nui te tawhiti i tua atu i te kōhao tawhiti rawa kia nui ai te wāhi mō te whakapiri kia huri i te whiunga whakahoki i te mea e huri ana i te pītiti whakapiri honohono e whakaputa ana i te kaha ki raro e pana ana i te whakapiri ki roto i ngā kōhao.
He aha te momo PCB ka taea te tā?
Ahakoa pēheapūmau,IMS,piko-mārōrāneiPCB whakangāwari(tirohia tā mātouTe Hanga PCB), mēnā kāore e ranea te kaha o te PCB ki te tautoko i te PCB kia papatahi rawa atu i runga i ngā rēri o ngā raina SMT, ka tono te kaihanga huihuinga PCB kia whakariteaKaikawe SMTte kawe rānei (i hangaia ki te Durostone).
He mea nui tēnei hei whakarite kia papatahi te PCB ki te tauira i te wā e tā ana. Mēnā kāore te PCB i te tino tautokona, ahakoa he pakari, he IMS, he pakari-piko, he piko rānei, ka arahi pea ki ngā hapa tā, pērā i te koretake o te whakapiri me te paru. Ko ngā tautoko PCB e tukuna ana me ngā mīhini tā he teitei pumau, ā, he tūranga ka taea te whakarite kia rite tonu te tukanga. Kei reira anō hoki ngā PCB whakarerekē, ā, he pai mō te huihuinga taha-rua.
PTirotiro i te Whakapiri Konukōre kua tāia (SPI)
Ko te tukanga tā whakapiri whakapiri tētahi o ngā wāhanga tino nui o te tukanga huihuinga mata. Ko te wawe o te tautuhi i tētahi hapa, ko te iti ake o te utu hei whakatika – he ture whai hua hei whakaaro ko te hapa i kitea i muri i te whakahounga ka 10 ngā wā te nui o te utu hei mahi anō i tērā i kitea i mua i te whakahounga – ko te hapa i kitea i muri i te whakamātautau ka 10 ngā wā anō te utu hei mahi anō. E mārama ana he nui ake ngā tūponotanga mō ngā hapa i roto i te tukanga tā whakapiri whakapiri i tētahi atu mea.Ngā Tukanga Hanga Hangarau Maunga Mata (SMT)Hei tāpiritanga, ko te whakawhiti ki te whakapiri whakarewa kore-mata me te whakamahinga o ngā wāhanga iti, kua piki ake te uaua o te tukanga tā. Kua whakamātauhia kāore ngā whakapiri whakarewa kore-mata e horapa, e "māku" rānei pērā i ngā whakapiri whakarewa mata tine. I te nuinga o te wā, me whai tukanga tā tika ake i roto i te tukanga kore-mata. Nā tēnei i akiaki te kaihanga ki te whakatinana i tētahi momo tirotiro i muri i te tānga. Hei manatoko i te tukanga, ka taea te whakamahi i te tirotiro whakapiri whakarewa aunoa hei tirotiro tika i ngā putunga whakapiri whakarewa. I RICHFULLJOY, ka taea e mātou te kite i ētahi hapa o te whakapiri whakarewa kua tāia, ngā putunga kāore i te ranea te rārangi, ngā putunga nui rawa, te whakarerekētanga āhua, te whakapiri ngaro, te whakapiri taupatupatu, te paninga, te hononga me te maha atu.
