I te wā e hoahoa ana, e hanga ana hoki i ngā papa hiko tā (PCB), he mea nui te tika. Ko tētahi o ngā wāhanga tino nui o te tukanga hanga PCB ko te mata keri e whakamahia ana hei keri i ngā kōhao mō ngā wāhanga me ngā tohu. I roto i tēnei aratohu, ka tūhuratia e mātou ngā momo momoNgā mata wiri papa PC, ā rātou whakamahinga, me pēhea te whiriwhiri i te mata keri tika mō tō kaupapa.
Akohia ngā mata wiri papa PC
He taputapu te mata keri PCB i hangaia mō te keri i ngā kōhao i roto i ngā PCB. Kua hangaia ēnei mata keri hei whakahaere i ngā rauemi me ngā matotoru ahurei o ngā PCB, tae atu ki te muka karāhe, te epoxy, me ētahi atu rauemi hiato. Ka taea e te mata keri tika te pā nui ki te kounga o tō PCB, mai i te pono o ō hononga ki te mahi whānui o tō taputapu hiko.
Ngā Momo o ngā Mata Wiri Papa Ara Iahiko Tānga
1. Mata wiri hurihuri: Koinei te momo mata wiri e whakamahia whānuitia ana mō ngā PCB. He hoahoa awaawa porowhita tō rātou e āwhina ana ki te whakakore i ngā paru i te wā e keri ana. He maha ngā whakamahinga o ngā mata wiri hurihuri, ā, ka taea te whakamahi i roto i ngā rahi kōhao rerekē, he mea rongonui i waenga i ngā kaitākaro tauhou me ngā tohunga ngaio.
2. Ngā Wiri Iti: Mō ngā mahi e hiahia ana ki ngā kōhao tino iti, he mea nui ngā wiri iti. Ka taea e ēnei mata wiri te wiri i ngā kōhao iti tae atu ki te 0.1 mm, he mea tino pai mō ngā PCB matotoru he iti te wāhi. Heoi, me āta whakahaere me ngā tikanga wiri tika kia kore ai e pakaru.
3. Ngā Mata Wiri Carbide: He mea hanga ki te tungsten carbide, e mōhiotia ana ēnei mata wiri mō tō rātou pakari me te kaha ki te pupuri i te koi mō te wā roa. He tino whai hua ēnei mō te wiri i roto i ngā rauemi pakeke ake, ā, he maha ngā wā e whakamahia ana i roto i ngā taiao hanga PCB ngaio.
4. Ngā Mata Wiri Kua Panihia ki te Taimana: Mō te tika me te roa o te wā, he kōwhiringa pai ngā mata wiri kua pania ki te taimana. Mā te paninga taimana ka maeneene ake te wiri, ā, ka whakaitihia te tūponotanga o te pakaru, te ngatata rānei o te rauemi PCB. He nui ake te utu o ēnei mata wiri, engari mō ngā kaupapa kounga, he pai te haumi.
Kōwhiria te mata wiri tika
I te wā e whiriwhiri ana i te mata wiri papa PC tika mō tō kaupapa, whakaarohia ngā āhuatanga e whai ake nei:
- Rauemi: Ka pā te momo rauemi e whakamahia ana mō te PCB ki te kōwhiringa o te mata wiri. Mō ngā papa hiko FR-4 paerewa, he nui te nuinga o te wā he mata wiri hurihuri, he mata wiri carbide rānei. Mō ngā rauemi motuhake ake, pērā i ngā PCB uku, PCB matua-konganuku rānei, ka hiahiatia pea he mata wiri pania taimana.
- Rahi o te Pū: Whakatauhia te rahi o te pū e hiahiatia ana kia keria. Mena kei roto i tō hoahoa ngā pū paerewa me ngā pū moroiti, ka hiahia pea koe ki te hoko i ngā wiri hurihuri me ngā mata wiri moroiti.
- Tikanga Keri: Ka pā anō hoki te tikanga keri ki te kōwhiringa o te mata keri. Mena kei te whakamahi koe i te mīhini CNC, me whakarite kia hototahi te mata keri ki ō taputapu. Tērā pea me whai whakaaro rerekē te keri ā-ringa, pērā i te mata keri kaha ake hei tu atu i te pēhanga.
- TAUHIRA: Ahakoa he mea whakamātau te whiriwhiri i te mata wiri iti te utu, mā te haumi ki tētahi mata wiri kounga teitei ka taea e koe te penapena wā me te moni mō te wā roa. Ka taea e tētahi mata wiri kounga iti te arahi ki te kino o te papa hiko me ngā hapa utu nui.
Hei whakamutunga
I te ao o te hoahoa me te hanga PCB, ka taea e ngā taputapu tika te hanga i te rerekētanga nui. Mā te mārama ki ngā momo mata wiri papa PC me ā rātou whakamahinga, ka taea e koe te whiriwhiri i te kōwhiringa pai rawa atu mō tō kaupapa. Ahakoa he tangata takaro noa koe, he tohunga rānei, mā te haumi ki tētahi mata wiri kounga teitei ka whakarite kia tika, kia pono hoki te hanga o ō PCB. Kia pai te keri!
