Mō ngā kaihangarau me ngā kaiwhakawhanake taputapu, ko te whakauru i tētahi motuka wiri moni ki roto i tētahi hoahoa papa hiko tā (PCB) me whai whakaaro nui ki ngā āhuatanga hangarau maha. Ahakoa kei te mahi koe i runga i tētahi waea atamai, i tētahi taputapu mau, i tētahi papa whakahaere ahumahi rānei, ka taea e tētahi motuka wiri moni kua whakauruhia pai (e mōhiotia ana ko te motuka wiri pancake, ko te motuka wiri papatahi rānei) te whakarei ake i te wheako kaiwhakamahi mā te whakarato urupare haptic whai hua. Kei roto i tēnei aratohu whānui ngā taipitopito hangarau me ngā mahi katoa hei whakarite i tētahi tukanga whakauru maeneene.
1. Te Mārama ki ngā Whakatakotoranga Hangarau oNgā Mōta Wiri Moni
1.1 Ngā Whakaritenga Ngaohiko me te Iahiko
Ngaohiko: Ko te nuinga o te wā, ka mahi ngā motuka wiri moni i te ngaohiko iti. He maha ngā tauira paerewa e mahi ana me te 3V, he mea tino pai mō ngā taputapu pākahiko pēnei i ngā mataarataki atamai me ngā taringa taringa ahokore. Heoi, i runga i te tono, ka taea te hanga motuka kia mahi i te 1.8V, 3.7V, 4V rānei. Hei tauira, i roto i ētahi pūnaha whakahaere ahumahi e hiahiatia ana he wiri kaha ake, ka whakamahia pea he motuka wiri momo moni 4V. He mea nui kia taurite te ngaohiko whakatauranga o te motuka ki te pūtake hiko i runga i tō PCB kia kore ai e ngoikore te mahi, e pakaru rānei.
Iahiko: Ko te iahiko e whakamahia ana e ngā motuka wiri moni i te nuinga o te wā mai i ētahi milriamp ki ngā tekau milriamp. Tērā pea ka kukumehia e tētahi motuka wiri moni iti 6mm te 40-60mA i te 3V. Mēnā ka nui ake te iahiko kua whakatauria, ka wera rawa, ka poto ake te roa o te ora o te motuka. Me whakarite kia taea e te ara iahiko whakahaere mana o tō PCB te tuku i te iahiko e hiahiatia ana me te kore e heke te ngaohiko.
1.2 Te Roa o te Arataki me te Momo Hononga
Te Roa o te Arataki: He mea nui te roa o ngā arataki e hono ana i te motuka wiri moni ki te PCB. He pai ngā arataki poto (hei tauira, 10 - 20mm) mō ngā tono he iti rawa te wāhi, pērā i ngā taputapu iti hei mau. Ka taea e ngā arataki roa (tae atu ki te 50mm, neke atu rānei) te whakarato i te ngāwari ki te whakanoho i te motuka kia matara atu i te PCB matua, he mea e tika ana pea mō ngā taputapu he uaua ngā whakatakotoranga o roto. I te wā e honohono ana i ngā arataki ki te PCB, kia tino wātea te roa kia kore ai e pāngia e te ahotea miihini i runga i ngā hononga honohono i te wā e whakahaerehia ana te taputapu.
Momo Hononga:
FPCB (Papa Arahiko Tānga Ngāwari): He tino ngāwari te hononga FPCB i roto i te hoahoa PCB. Mā te āhua ngāwari o te FPCB ka taea te whakatere ngāwari i roto i ngā wāhi kuiti me te taha o ngā hanganga uaua o roto o ngā taputapu. Ka taea te piko, te whakapiko, te takai rānei hei whakanoho i te motuka wiri moni ki te wāhi e tika ana. He tino rongonui tēnei momo hononga i roto i ngā taputapu angiangi me te kiato pēnei i ngā waea atamai me ngā mataarataki atamai, he mea nui te whakaiti i te matotoru whānui me te whakanui i te whakamahinga o te wāhi. I te whakamahi i te hononga FPCB, ka honoa te motuka ki tetahi pito o te FPCB, kātahi ka whakapirihia, ka honoa rānei tetahi pito ki te PCB matua. Ka āwhina hoki tēnei tikanga hononga ki te whakaiti i te ahotea miihini i runga i te motuka i te wā e huihui ana me te whakahaere i te taputapu.
Hononga - Kāhua: Mā ngā hononga e hangai ana ki te hononga ka taea te wetewete, ka taea hoki te tango. Mā te hononga momo hononga, ka tae mai te motuka wiri moni me te hononga kua oti te tāpiri, ā, kua whakanohoia he putanga rite ki te PCB. Mā tēnei ka māmā ake te tāuta, te tango, te whakakapi rānei i te motuka i te wā e hangaia ana, mō ngā kaupapa tiaki rānei. He kōwhiringa pai mō ngā taputapu e hiahiatia ana te huihuinga me te wetewete tere, i te wā rānei e hiahia ana koe ki te whakawhiti i ngā motuka me ngā whakatakotoranga rerekē. Hei tāpiri, ka taea e ngā hononga momo hononga te tuku i te pono o te whakapā hiko, ā, he iti ake te tūponotanga ki ngā take e pā ana ki te whakapiripiri, ki te whakaritea ki ētahi atu tikanga hononga.
3. Te Whakaurunga Hiko me te Hoahoa Ara iahiko
3.1 Ara Pūnaha Hiko
Te Tātari me te Whakahaere: I te mea ka taea e ngā motuka wiri moni te whakaputa haruru hiko i te wā e whakahaerehia ana, he mea nui kia whakauruhia te tātari me te whakahaere ki roto i te ara iahiko tuku hiko. Ka taea te tāpiri i tētahi tātari RC (ātete - pūnga) māmā i waenganui i te pūtake hiko me te motuka hei whakaiti i ngā pikinga me te haruru o te ngaohiko. Hei tāpiri, ki te teitei ake te ngaohiko tuku hiko i te ngaohiko kua whakatauria o te motuka, me whakamahi he ara iahiko whakahaere ngaohiko (pēnei i te LDO - Low Dropout regulator) hei whakaheke i te ngaohiko.
Mana Whakawhiti: Hei whakahaere i te mahi a te motuka wiri moni, me whakamahi i tētahi ara iahiko whakawhiti. Ka taea tēnei te whakatinana mā te whakamahi i ngā transistors (hei tauira, ngā MOSFET N-channel) me ngā IC taraiwa motuka motuhake rānei. Mā te ara iahiko whakawhiti ka taea e koe te tahuri me te whakaweto i te motuka ina hiahiatia, hei tauira, hei whakaputa i ngā whakatūpato wiri, hei urupare rānei.
3.2 Mana Tohu
Te Whakarerekētanga Whānui-Pā (PWM): He tikanga noa te PWM e whakamahia ana hei whakahaere i te kaha wiri o ngā motuka wiri moni. Mā te whakarerekē i te huringa mahi o te tohu PWM, ka taea e koe te whakarite i te ngaohiko toharite e pā ana ki te motuka, ka whakahaere i te kaha wiri. Hei tauira, ko te huringa mahi 50% ka hua ake he wiri kaha-waenga, ko te huringa mahi 100% ka hua ake te kaha wiri mōrahi.
Mana Arorau: Honoa te tohu mana mai i tō pūmana iti, i tētahi atu ara iahiko arorau rānei ki te ara iahiko whakawhiti o te motuka. Me whakarite kia whakamahia ngā ara iahiko whakawhiti taumata tika mēnā he rerekētanga ngaohiko i waenga i te ara iahiko arorau me te taraiwa motuka.

Tuatoru, whakamahia he rauemi ārai huri noa i te motuka mēnā e tika ana, inā koa i ngā tono e teitei ana te aro ki te haruru.
Q3: Me aha ahau mēnā kāore te motuka wiri moni e wiri pērā i te mea e tumanakohia ana i muri i te whakaurunga?
A: Tuatahi, tirohia te ngaohiko me te iahiko o te pūhiko kia tino rite ki ngā whakaritenga o te motuka. Kātahi, manatokohia ngā hononga whakapiri o ngā taura ki te PCB kia tino kore he ara iahiko tuwhera, he ara iahiko poto rānei. Tirohia hoki te tohu whakahaere ki te motuka kia tino tika ai te mahi.
