Whakaurunga o te PCB LED
He aha te LED? Kia whai taipitopito a Wikitōria i raro nei.
Ka whakaurua ngā LED ki ngā papa ara iahiko tāngia, ā, ka whakarahia ki tētahi maramara e whakaputa ana i te mārama mā ngā tūhononga hiko. Ka whakamahia he totohu wera me te turanga uku hei tūhono i ngā rīwai. E kore e mōhiotia, ko ngā PCB LED te uho o te tīramarama LED. He ngāwari noa iho te whakaputa wera o te PCB LED, engari he uaua ki te whakamātao mā te whakamahi i ngā tikanga tūturu.
I tēnei wā, ko te pōkaitanga SMT te puka pōkai e tino whakamahia ana i roto i ngā taupānga LED. I te nuinga o te wā, he whāiti te mārama e whakaputaina ana e tētahi wae LED kotahi. Nō reira, ka whakamahia e te rama ngā wae LED maha kia whiwhi ai i te mārama rawaka. Pēnei i ētahi atu pūrere semiconductor, ko te PCB te tikanga pai rawa mō te tūhono hiko i ngā wae LED. Ko te PCB me ngā wae LED e kīia nuitia ana he "PCB LED".
Nga painga o te LED.
He maha ngā painga nui o ngā PCB LED, nō reira ka taea te whakauru ki roto i ngā taupānga rama maha.

Tirohanga Whānui
He aha te mīhini Wikitōria?
Ko te mīhini wikitōria he tikanga whakanao mō te tango rauemi. Ka whakamahi i ngā utauta tapahi koi, e wātea ana i roto i ngā momo hanga me ngā rahi, e whakahaeretia ana e te rorohiko. Ko te wikitōria ko te Mana Tau Rorohiko.
He pēhea te mahi o te mīhini Wikitōria
Ka tīmata te mīhini wikitōria ki tētahi rorohiko, e whakarite ai ngā kaihoahoa i tētahi wāhanga mā te whakamahi i te pūmanawa CAD (Computer-aided Design). Kātahi ka tahuri tēnei wāhanga mamati ki tētahi hōputu ka mōhiotia e tētahi mīhini Wikitōria.
Ka tukuna ngā tohutohu ki te mīhini Wikitōria mā te āhua o te "G-Code" i muri iho ka tīmata te mīhini ki te tapahi.
Ko te nuinga o ngā mīhini Wikitōria he "tēpu mahi" me te pūrere pupuri mahi hei pupuri i tētahi paraka rauemi — e mōhiotia ana ko te "mahi" — ki te wāhi. Ka neke, kāore rānei te tēpu mahi, i runga anō i te kāhua o te mīhini.
Ina tīmata te mīhini, ka whakapā atu te utauta tapahi ki te taputapu mahi, ka tapahi atu i ngā apa rauemi. Ka nekehia te utauta me te tukanga rānei, ka tere rānei te tītaka e ai ki ngā tohutohu G-Code kia tapahia ai ngā tapahi ki ngā wāhi tika kia mutu rā anō te wāhanga.
Ngā momo mīhini Wikitōria rerekē
Kei roto i ngā mīhini wikitōria ko ngā mira Wikitōria, ngā mīhini huri Wikitōria (ngā mīhini hurihuri rānei), ngā pouara Wikitōria, me ngā mīhini Mīhini Hiko (EDM).
He utauta tapahi tītaka tā ngā mira wikitōria ka nekehia ki ngā wāhi rerekē o te mahi hei tapahi, ā, ka taea te whakamahi hei hanga i ngā pata rerekē. Ka mahi kē ngā mīhini wikitōria, ka tītaka te mahi ki tētahi utauta tapahi tū, ā, ka whakamahia hei hanga i ngā wāhanga porotakaroa.
He rite tonu ngā pouara Wikitōria ki ngā mira Wikitōria, engari he iti iho te hiko, ā, kāore e taea te tapahi i ngā rauemi uaua rawa. Heoi anō, ka tere ake rātou i ngā mira Wikitōria.
Ka whakamahi te EDM i ngā putanga hiko (kora) kaua ko te utauta tapahi koi hei tapahi rauemi. Kāore he whakapā ā-tinana i waenganui i te utauta me te mahi.
Ko ngā mīhini wikitōria e tautuhia ana e te maha o ngā toki. Ko te tikanga o te nui ake o ngā toki ka taea e rātou te neke i tā rātou utauta, i te wāhanga mahi rānei i roto i te maha o ngā huarahi, ka nui ake te ngāwari o te tapahi me te āhei ki te hanga i ngā wāhanga matatini ake i roto i te wā poto ake.
