He aha te take i whakamahia ai te whakamararatanga wera o te mg4 ev hei pā hau, kaua hei whakamatao wai?
I roto i ngā pūnaha hiko o ngā motuka, he wero tonu te whakahaere pāmahana, me mahi noa te pūnaha i raro i te pāmahana taiao o -40°C ~ + 65°C. Ka piki ake hoki te pāmahana o te taiao i roto i te whare ki te 20°C, nō reira ko te pāmahana taiao mōrahi e tika ana kia tū atu te papa PCB ka eke ki te + 85°C.
Kātahi ka aro nui atu ki te rohe, pērā i te pūtake hiko, te CPU me ētahi atu kōwae, ka nui ake te wera e pau ana, ā, ka nui ake te pāmahana o te taiao i roto i te anga, ā, kua tata te taiao kino ki te rohe pāmahana o te maha o ngā maramara. Nō reira, i te wāhanga tuatahi o te hoahoa pūnaha, me whakamahere te rautaki Whakahaere Wera me te hoahoa i ngā mahi e rite ana.
He māmā noa iho, he uaua hoki, engari ko te mehua whai hua mō te whakamarara wera ko te tāpiri i tētahi pā hau, ā, mā tēnei ka piki ake te utu hoahoa me te haruru mīhini. Nō reira, ko ā mātou whakaritenga mō te hoahoa i ngā ara iahiko pā hau e ahu mai ana i ēnei pūtake taketake e rua:
1), me māmā te ara iahiko, me iti te utu;
2), he rite te tere o te pā ki te haruru, nō reira me ine me te whakahaere i te tere o te pā. Ka whakarerekē te pūnaha i te tere o te pā kia rite ki te pāmahana o te taiao, me te whakahaere tere kore taahiraa, ā, ka whai kia taurite te pai o te tohatoha wera me te haruru.
He ngāwari te pakaru o te whakamahinga o te whakamatao wai, ā, me whakakapi me te tiaki tonu, ā, he maha ngā pakaru o te motuka, kāore e tika ana mō te whakamahi i ngā pūnaha whakamatao wai.
