Te raupapa whakaata SMD/SMT a Leader Micro Electronicmōtini wiri itiHe kōwhiringa pai rawa atu ēnei mō te hanga papatipu aunoa, tere-teitei mā te whakamahi i ngā mīhini tiki me te whakanoho. Koinei anake te raupapa motuka wiri e wātea ana i runga i te rīpene me te rīra. Mena ka whakapiri ā-ringa te motuka ki te PCB (arā, te hanga tauira), kaua e whakamahi i te rere, nā te mea ka uru pea tēnei ki te motuka ka pakaru. Kāore e taea te horoi i tēnei raupapa motuka i muri i te tukanga whakahoki.
Tō mātoumōtini wiri itiKo ngā motuka wiri SMD, he mea tākai ki runga i te rīpene/rīra, 1000 ngā wahi mō ia rīra, ā, kua hangaia kia tangohia tika mai i te rīra. He kōwhiringa pai rawa atu ēnei mō te whakaputa papatipu nui. He "uho" tō rātou e āhei ai rātou ki te tu atu i ngā pāmahana teitei e pā ana ki te tukanga whakapiringa whakawhiti. Ka taea e ēnei motuka wiri SMD te pakaru i te wera nui. Kia mahara ki te whai i te kōtaha pāmahana oumu whakawhiti kei roto i te pepa raraunga motuka. Mena ka whakapirihia ā-ringa ēnei motuka (arā, te hanga tauira), kaua e whakamahi i te rere, engari whakamahia he rino iti te mana mō te wā poto rawa. Kia mahara ko ēneingā motuka wiriKāore e taea te horoi.
Whakapā mai o te Kōangamōtini wiri smt:
He kōwhiringa pai rawa atu tēnei raupapa o ngā motuka wiri mata, me ngā hononga puna, mō ngā take maha. Kāore i rite ki ā mātou motuka SMT Reflow, kāore ēnei motuka i hangaia kia whakapirihia ki te PCB. Ka hono noa ngā puna whakapā o ēnei motuka ki ngā papa whakapā o te PCB. He maha ngā painga motuhake o tēnei momo motuka e whai ake nei:
Utu Iti: He iti iho te utu o tēnei raupapa motuka i te 10% i ngā motuka wiri SMT reflow.
Te Whakawhiti Pūngao Wiri Whai Hua: Ka taea te whakamau i ēnei motuka ki roto i te pouaka kirihou o te whare hua, kia māmā ake ai te rongo, kia iti ake ai hoki te makuku, pērā i ngā motuka kua whakamau ki runga i te PCB.
Te Pūmautanga Nui Ake: E mōhiotia ana ka whai wāhi te wiri ki ngā rahunga o te hua. Mā te whakaiti i te nui o taua whakawhiti pūngao ki te PCB ka āwhina i tēnei āhuatanga.
Te Āhua Pai o te Ratonga: I ngā tono e pāngia ana te motuka e ngā huringa mahi tino nui, e nui ake ana i te roa o te ora kua whakaritea mō ngā motuka, ka puta pea te pakaru wawe o te motuka. He tere, he whai hua hoki te whakakapi i tēnei momo motuka wiri, ahakoa i te parae, nā te mea kāore he hononga e hiahiatia ana hei tango me te whakakapi. (kei raro tonu)
