Ko te miihini matua o te whakamātautau tika: te tono o ngā motuka stepper moroiti i roto i ngā urutau whakamātautau ngira hiko

I roto i te mara o te hanga hiko tere-teitei me te tino tika, ka mahi ngā urutau whakamātautau ngira hiko hei kaitiaki tatau hei whakarite i te kounga o ngā PCB, ngā maramara, me ngā kōwae. I te mea ka iti haere te mokowā o ngā pine wāhanga, ka piki haere te uaua o te whakamātautau, kua eke ngā tono mō te tika me te pono i roto i te whakamātautau ki ngā taumata kāore i kitea i mua. I roto i tēnei hurihanga o te ine tika, he mahi nui tā ngā motuka hiko iti hei "uaua tino tika". Ka rukuhia e tēnei tuhinga te mahi tika a tēnei matua hiko iti i roto i ngā urutau whakamātautau ngira hiko, ka akiaki i te whakamātautau hiko hou ki tētahi wā hou.

一.Kupu Whakataki: Ina hiahiatia te tika o te whakamātautau kia tae ki te taumata maikorona

Kua kore e ranea ngā tikanga whakamātautau tuku iho mō ngā hiahia whakamātautau o ngā mōkihi BGA, QFP, me te CSP o ēnei rā. Ko te mahi matua o tētahi urutau whakamātautau ngira hiko ko te taraiwa i ngā tekau, i ngā mano rānei o ngā probe whakamātautau hei whakatū hononga ā-tinana, ā-hiko pono hoki ki ngā pūwāhi whakamātautau i runga i te waeine e whakamatautauria ana. Mēnā he iti noa te tūnga, te pēhanga kāore i te ōrite, te pā kore pumau rānei, ka arahi pea ki te korenga o te whakamātautau, te whakatau hē, te kino rānei o te hua. Ko ngā motuka stepper moroiti, me ō rātou mana mamati ahurei me ngā āhuatanga tino tika, kua noho hei otinga pai hei whakatika i ēnei wero.

一.Te tikanga mahi matua o te motuka stepper moroiti i roto i te urutau

Ehara te whakahaere o te mōta hiko iti i roto i te urutau whakamātautau ngira hiko i te hurihanga noa iho, engari he raupapa o ngā nekehanga tika me te whakahaere. Ka taea te wehewehe i tōna tukanga mahi ki ngā mahi matua e whai ake nei:

1. Te whakarārangi tika me te tūnga tuatahi

Rerenga mahi:

Ngā tohutohu mō te whiwhi:Ka tukuna e te rorohiko manaaki (kaiwhakamātautau) ngā raraunga taunga o te wāhanga hei whakamātautau ki te kāri whakahaere nekehanga, ka hurihia hei raupapa tohu pātere.

Te nekehanga whakawhiti pātere:Ka tukuna ēnei tohu pātere ki te taraiwa o te motuka hiko iti. Mā ia tohu pātere ka akiaki i te rakau motuka kia huri i tētahi koki pumau – he "koki hikoinga". Mā te hangarau taraiwa hikoinga iti matatau, ka taea te wehewehe i tētahi koki hikoinga katoa kia 256, neke atu rānei ngā hikoinga iti, kia tutuki ai te mana whakahaere nekehanga taumata-mikiromita, taumata-iti-mikiromita rānei.

Te tūnga whakatinanatanga:Mā roto i ngā tikanga tuku pēnei i ngā tīwiri mata tika, ngā whitiki wā rānei, ka peia e te motuka te waka kua utaina ki ngā whakamātautau kia neke i runga i ngā papa tuaka-X me te tuaka-Y. Ka nekehia tikatia e te pūnaha te rarangi whakamātautau ki te tūranga i runga ake i te pūwāhi hei whakamātautau mā te tuku i tētahi tau motuhake o ngā pātere.

2. Te whakahaere pēhanga me te pēhanga whakahaere

Rerenga mahi:

Te whakatata ki te tuaka-Z:I muri i te otinga o te tūnga papatahi, ka tīmata te mahi a te mōta hiko iti e kawenga ana mō te nekehanga o te tuaka-Z. Ka whiwhi tohutohu, ka panaia te pane whakamātautau katoa, te waeine tirotiro kotahi rānei kia neke poutū ki raro i te tuaka-Z.

Te whakahaere tika i te haere:Ka pēhi mārie te motuka i ngā takahanga iti, kia tika ai te whakahaere i te tawhiti haere o te mīhini pēhi. He mea nui tēnei, nā te mea ka kore e pai te pā atu mēnā he poto rawa te tawhiti haere, engari mēnā he roa rawa te tawhiti haere, ka pēhia rawatia te puna o te pūwero, ka nui rawa te pēhanga me te kino ki te papa whakarewa.

Te Pupuri i te Taipana hei Pupuri i te Pēhanga:Ina tae te pūwero ki te hohonutanga o te hononga kua whakaritea ki te pūwāhi whakamātautau, ka mutu te hurihuri o te motuka hiko iti. I tēnei wā, ka mau tonu te motuka, me tōna taipana pupuri teitei, kia mau tonu ai te kaha whakaheke pumau me te pono, me te kore e hiahiatia he tuku hiko tonu. Mā tēnei ka mau tonu te hononga hiko puta noa i te huringa whakamātautau katoa. Ina koa mō te whakamātautau tohu auau-tiketike, ko te hononga miihini pumau te tūāpapa o te pono o te tohu.

3. Matawai maha-ira me te whakamātautau ara uaua

Rerenga mahi:

Mō ngā PCB matatini e hiahia ana kia whakamātautauhia ngā wāhanga i ngā wāhi rerekē maha, i ngā teitei rerekē rānei, ka whakauruhia e ngā urutau ngā motuka stepper moroiti maha hei hanga i tētahi pūnaha nekehanga maha-tuaka.

Ka whakarite te pūnaha i te nekehanga o ngā momo motuka e ai ki tētahi raupapa whakamātautau kua whakaritea i mua. Hei tauira, ka whakamātautau tuatahi i te Rohe A, kātahi ka neke ngā motuka XY i roto i te mahi tahi hei neke i te rarangi tirotiro ki te Rohe B, ā, ka pēhi anō te motuka tuaka-Z ki raro mō te whakamātautau. Ka tino whakapai ake tēnei aratau "whakamātautau rere" i te pai o te whakamātautau.

I roto i te tukanga katoa, mā te kaha o te mahara tūnga tika o te motuka ka taea te whakahoki i te tika o te tūnga mō ia nekehanga, ka whakakore i ngā hapa tāpiripiri.

一.He aha i whiriwhiri ai i ngā motuka hiko iti? – Ngā painga o te tikanga mahi

Ko te tikanga mahi tika kua whakahuatia ake nei i ahu mai i ngā āhuatanga hangarau o te motuka stepper moroiti tonu:

Te Whakamatihiko me te Tukutahitanga Pātene:He tino ōrite te tūnga o te mōta ki te maha o ngā pātere whakauru, e āhei ai te whakaurunga maeneene ki ngā rorohiko me ngā PLC mō te whakahaere mamati katoa. He kōwhiringa pai rawa atu mō te whakamātautau aunoa.

Kāore he hapa tāpiripiri:I raro i ngā āhuatanga kore-taumaha, kāore te hapa hikoinga o te mōtini hikoinga e piki haere mārire. Ko te tika o ia nekehanga e whakawhirinaki ana ki te mahi ā-roto o te mōtini me te taraiwa, kia tika ai mō te whakamātautau roa.

Hanganga kiato me te kiato taipana teitei:Mā te hoahoa iti nei ka taea te whakauru ngāwari ki roto i ngā taputapu whakamātautau kiato, me te whakarato hoki i te taipana e ranea ana hei akiaki i te huinga tirotiro, kia tutuki ai te taurite tino pai i waenga i te mahi me te rahi.

一.Te Whakatau i ngā Wero: Ngā Hangarau hei Whakapai ake i te Whai Hua o te Mahi

Ahakoa ōna painga nui, i roto i ngā mahi whaihua, ka pāngia hoki ngā motuka hiko iti e ngā wero pēnei i te haruru, te wiri, me te ngaronga o ngā hiko. Hei whakarite kia pai te mahi i roto i ngā urutau whakamātautau ngira hiko, kua whakamahia e te umanga ēnei tikanga arotau e whai ake nei:

Te tono hōhonu o te hangarau taraiwa hikoi-iti:Mā te micro-stepping, ehara i te mea ka pai ake te taumira anake, engari ko te mea nui ake, ka whakangawarihia te nekehanga o te motuka, ka whakaitihia te wiri me te haruru i te wa e ngoki ana i te tere iti, ka pai ake te hononga o te probe.

Whakataki o te pūnaha whakahaere porowhita-kati:I ētahi tono tino tono nui, ka tāpirihia ngā kaikōwae ki ngā motuka hiko iti hei hanga i tētahi pūnaha whakahaere porowhita-katia. Ka aroturukihia e te pūnaha te tūranga tuturu o te motuka i te wā tūturu, ā, ina kitea he hapa i te takahanga (nā te ātete nui rawa atu, nā ētahi atu take rānei), ka whakatika tonutia, ka whakakotahi i te pono o te whakahaere porowhita-tuwhera me te taurangi haumaru o tētahi pūnaha porowhita-katia.

一.Whakamutunga

Hei whakarāpopototanga, ko te whakahaere o ngā motuka hiko iti i roto i ngā urutau whakamātautau ngira hiko he tauira tino pai mō te huri i ngā tohutohu matihiko ki ngā nekehanga tika i roto i te ao tūturu. Mā te mahi i tētahi raupapa o ngā mahi ka taea te whakahaere tika, tae atu ki te whiwhi pātere, te mahi nekehanga hiko iti, me te pupuri i te tūranga, ka mahia e ia ngā mahi nui o te whakarite tika, te pēhi ka taea te whakahaere, me te matawai uaua. Ehara i te mea he wāhanga whakahaere matua anake mō te whakatutuki i te aunoatanga whakamātautau engari he miihini matua hoki mō te whakarei ake i te tika, te pono, me te whai huatanga o te whakamātautau. I te mea kei te whanake tonu ngā wāhanga hiko ki te whakaitiiti me te kiato teitei, ka haere tonu te hangarau o ngā motuka hiko iti, inā koa ko tana hangarau hiko iti me te whakahaere porowhita kati, ki te akiaki i te hangarau whakamātautau hiko ki ngā taumata hou.
