Kei te whakamahia ngā tūtohinga o te hangarau matatika hei whai wāhi i ngā putanga whakapuaki tino pai, mā te whakamahi i ngā hunga hangarau matua pēnei i te CAD (Tuhinga Wāhi Rorohiko) me te CNC (Whakahaere Tauira Rorohiko). E mahi ana ēnei hunga hangarau i ngā whārite tata ki te whakapuaki, e hiahia ana ki te whai i ngā huataki whakapuaki kē, inaianei kei roto i te whenua hanga rorohiko. Mā te whakamahi i ngā moemoeā hangarau ka noho pai ake ngā huataki whakapuaki, ko tēnā ka heke i te nginga o ngā matakuaka. Ko tēnei mahi tino mīharo i te whakapuaki kei te whakangungu i te whanaketanga me te whakanuiwhakapono i ngā momo rorohiko, ka puta he mea hanga e kite ana i te wā e whai mana ana, ka noho pai tonu i te rangatiratanga tuatahi mō te wā o tana ao.
Kei te whakangungu ngā mahere mōhiotanga hua i roto i te hanga i ngā rara moana, e whai ana i ngā whakamātau matihiko me te whakaae ki ngā paerewa katoa o te whenua, pēnei i ēnei tūrite e whakaritea nei e IPC (Tauākī mō ngā Pātai Whirinaki) me ISO (Kāwana Whaimana Mōhiotanga Arotake). E whakarite ana ēnei tūrite i ngā whakahaere moana kia tae atu ki ngā tohu hua kitea ai hei huarahi pai. Ki te whakatika i ngā whakahaere mōhiotanga nui rawa atu, ka whakamana i te rorohiko whakawhitinga me te itinga i ngā mate hanga. Ki te tiimata i ēnei tūnga pai whakahaere, ka whakapono ngā hangaenga i a rātou whakahaere moana kia pai, kia wehe, me te whakamahere pai hoki.
Ki te whakarite i ngā here kai tiaki i te taiao, e hīkohia ana te whakaaro RoHS i ngā matū hāpai. Nui rawa ngā matū hāpai kore-parekura hei āwhina i te iti i ngā uiui hauora me te tiaki i tōna taiao. Ki te pērā ka noho kore i ngā rerekē paihikara pēnei i te parekura, ka iti nei ngā wā kua tae ki te mate i te parekura me te whakawātea i te taiao. Kei te nui ake ngā whakamahi o ngā matū e whakaaro RoHS i roto i te ao o ngā whatunga, kei reira i runga i te 80% o ngā hangaenga kua whakaae kia whakamahia ēnei matū. Ko tēnei whiti kē ka takoto ki ngā tikanga ture, ā, ka whakapai anō hoki i te ingoa hanga o ēnei hangaenga e whai mana ai i te whakahaere me te haumanu.
Te noho āwhi o ngā uku kore-parekura he mea nui, e kīia ana e kāore i te whakarite ki ngā wāhi wehe werawera. E taea ana e ēnei uku whakamana i te werawera kino, mea nui nei mō ngā whenua pūnaha motokā me ngā pūnaha rorohiko, kei reira ngā whatu e kite ana i te werawera roa. Nā ngā hiranga hou i runga i ngā momo hangarau whakamana uku wehe werawera, ka whakapai i te roanga o ngā mahi, e tirotiro ana hei whakatutuki i ngā tūmomo me ngā pūnaha ki runga i ngā wā e roa ana. Hei tauira, i roto i te pūnaha motokā, e nui ana te hē ki te whakamana i ngā hononga uku hei whakatutuki i te whakahaere o ngā mounga e rorohiko ana i te werawera kino, ka whakaiti i te mate me te whakatū ake i te wā o ngā whatu rorohiko.
He tikanga whai take moana ā-matihiko, he mea hiahia te kawe i ngā tūtohi hangi rite ki ngā mahi hangi. E rite ana ngā momo nei ki ngā whakamahi e rahi, e tika ana hei whakamahi mō ngā mahi hangi ā-rite pūnaha me ngā mahi hangi ā-meha. Ko te whiu o ngā tohu hangi me ngā maukuuku neke atu he mea nui, e āheinga ana ki ngā mahi ā-wahitata. Hei tauira, he pai rawa ētahi maukuuku hangi ki te whakamahi i ngā āhuatanga matihiko iti, ahakoa kei runga i ngā wāhi mehemea e hiahia ana ki te tahuri i ngā waewae roa i ngā hononga meha. I te kīno i te whiriwhiria mai ngā maukuuku hangi, ka whakaritea e ngā tohunga ngā āhuatanga pūnaha me ngā wā o te tahuri ki te whakamahi pai rawa.
He wāwāhi āhuarangi rerekē ngā tāwai hāngai me ngā puhipuhi flux hei whakamana i ngā hiahia hāngai kē, pēnei i ngā rorohiko me ngā whakawehenga. Ka hangaia ngā tāwai hāngai mo ngā matatika īnāianei, tonoia ngā huatau rerekē me ngā whakauru whenu ki te paihere i ngā mahi rerekē. He nui te hunga o ngā puhipuhi flux i te whakangungu i te hononga mete me te whakaiti i te whakaputuputu. Kua take noa iho te whiriwhiringa i te tino tāwai hāngai me te flux tōtika mō te kawekeke ake o te mahi. Ko te whakaaro i ngā tikanga tūmatawhiti, pēnei i te momo whenu e hāngai ana me te rangatira o te hono, ka awhina i te whiriwhiringa i te tino tāwai me te flux pai mō ngā mahi hāngai.
Kei te whai aha te toki here lead-free RoHs o Zhengxi i ana āhuatanga nui, inanahi ko tana whiuwhiu ki te uruāki me ana pūkenga moe-ā-hua. Kua hangaia tēnei toki here kia taea te hoki haere i ngā taiao kino, koia nei he pai tōna mō ngā tūranga whakamutunga i roto i ngā pūnaha matihiko me ngā rorohiko. E ai ki ngā tohutohu whenua, kei te whai ake ia i ngā tohutoro whakahaere herehere nui, ka mutu kua pau ngā whakamatakitaki herehere nui, e whakapakari ana i tana tiariaranga me te pai o tana mahi. Ko ngā whakahoki mai i ngā kaiwhakamahi e whakaatu ana i te whaimana me te mahi o enei toki i roto i ngā kaupapa o te ao rēaaliti, me te whangai ake i te pai o tana mahi i te itinga wā i roto i ngā mahi.
Nō te nui o ngā whakamahi ā-wāhanga, he kētore ā-pūtau rāwhiti tonu te hiranga, e kīia ana e te hunga mōhio i tēnei take, inaianei i roto i ngā mahi taurangi, nā te pai rawa o ōna āhuatanga tuatahi me te wānanga ki te whakamahi. Kua hanga te kētore pūtau rāwhiti a Zhengxi i runga i ngā paerewa tiaki i te oranga me ngā paerewa hokoaro, e whai ana i ngā ture whenua. E ai ki ngā whakaaetanga, ka tino pai ngā āhuatanga whakapiri, e noho pai ana i waenganui i ngā whakatikatika taurangi me ngā whakatūpū. Ko ngā toihitori me ngā taurangi e whakanuia ana i enei kētore mo te pai rawa o ratou, ka whakamahi i aua ki te whakapai i ngā hononga me te iti i te uara o te whakapae kētore.
Te tūruki 63/37 mai i a Zhengxi e whai ana i tētahi whakawhitinga matua e hāngai ana ki ngā tono whakapā tahuhu rīpea. E whakaaweawe ana ia i te pūnaha here iti, pai noa ki te hanga i ngā huataki whakapā pai me te kiko mōhiohio, ki te kore e whakarerekē i ngā whatu whakamahia. Ko tēnei tin o pai tuatahi e whai ake ana i ngā āhuatanga pai, ina whai huarahi rangona pai me te painga nui, ka heke i ngā take e pā ana ki te whakapakari me te whakapakari wera. Ko tana mana ki runga i ngā tohunga e tino whai ake nei, ina tae atu ki tana kotahi me tana whakapono i waenganui i ngā mahi whakapā rerekē.
Te tāwhiti pūtaiao Sn99.3Cu0.7 i whakaritea e Zhengxi he mea nui i ngā whakamahi whakapī i te āhua matihiko. I hanga hei whakarerekē i te kaihapa, ka whakaiti i ngā rereke o muri i te tāwhiti, whakapai i te āhua me te hāpai i ngā hononga tāwhiti. E whai ana tēnei tāwhiti i te mana ki te hanga i ngā hononga pai, whai wāhi, he mea nui mo te hanga i ngā raraunga matihiko hiranga. Ka whakaatu ngā whakaaetanga i waenganui i tōna tino tika i ngā mahi whakapī, kei reira te momo me te kīwaha.
Te tāwhiti porohita 60/40, e whai ake nei i tōna koko mēhanga iti, e pai ana ki ngā mahi tāporohita tirotiro me ngā mahi wānanga. Ki te iti ā-matihiko tōna waewae, ka riro ēnei momo pūngao, ko te whakamahi hei whakatika i ngā hononga porohita, me te whakaawe i tēnei i ngā mahi e hiahiatia ana te kuhu o te rongoā ki ngā whatu iti. Ko te whakamahi i te porohita koko mēhanga iti pērā i tēnei tāwhiti 60/40 he pai tonu ki te whakapae i te roa o ngā whatu, nā te mea ka mau tonu ngā hanganga hono rangatira. Ki te whakaatu i ngā tūtohu koko mēhanga nui, ka tuku mai tēnei tūtohu he wāhi kotahi me te kawea i te taiao tāporohita kia whaimana.
