Ko te pūwero PCB te reo whakapā mō te whakamātautau hiko, he wāhanga hiko nui, ā, ko te kaikawe mō te hono me te kawe i ngā wāhanga hiko. He whānuitia te whakamahinga o te pūwero PCB hei whakamātautau i te tuku raraunga me te whakapā arataki o te PCBA. Ka taea te whakamahi i ngā raraunga o te mahi tuku arataki o te pūwero hei whakatau mēnā kei roto te hua i te whakapā noa, me te mēnā he noa ngā raraunga mahi.
I te nuinga o te wā, he maha ngā whakaritenga o te pūwero PCB, e toru ngā wāhanga matua: tuatahi, ko te ngongo ngira, he mea hanga ki te koranu parahi, he mea whakakikorua ki te koura. Ko te tuarua ko te puna, ko te waea rino piano te nuinga, ā, ko te puna rino he mea whakakikorua ki te koura. Ko te tuatoru ko te ngira, ko te nuinga he whakakikorua ki te nikara maitai taputapu (SK), he whakakikorua koura rānei. Ka huihuia ngā wāhanga e toru o runga ake nei ki roto i tētahi pūwero. Hei tāpiri, he ringaringa o waho, ka taea te hono mā te whakarewa.
Momo tirotiro PCB
1. Te tirotiro hangarau mōhiohio
Ko te mokowā e whakamahia whānuitia ana ko te 1.27mm, 1.91MM, 2.54mm. Ko ngā raupapa e whakamahia whānuitia ana ko te 100 raupapa, 75 raupapa, me te 50 raupapa. E whakamahia whānuitia ana ēnei mō te whakamātautau ara iahiko ipurangi me te whakamātautau mahi. He maha ake te whakamahinga o te whakamātautau ICT me te whakamātautau FCT hei whakamātautau i ngā papa PCB kau.
2. Pūwero pito rua
E whakamahia ana mō te whakamātautau BGA. He pakupaku, ā, me mahi toi teitei. Ko te tikanga, ka whakamatautauria ngā maramara IC waea pūkoro, ngā maramara IC pona, ngā rorohiko papa me ngā maramara IC whakawhitiwhiti kōrero. Ko te whānui o te tinana ngira kei waenga i te 0.25MM me te 0.58MM.
3. Pūwero whakawhiti
E rua ngā ara iahiko o tētahi pana kotahi hei whakahaere i te mahi tuwhera noa me te mahi kati noa o te ara iahiko.
4. Pūtirotiro auau teitei
E whakamahia ana hei whakamātautau i ngā tohu auau-tiketike, me te mowhiti whakamarumaru, ka taea te whakamatautau i roto i te 10GHz me te 500MHz me te kore he mowhiti whakamarumaru.
5. Pūtiro hurihuri
Kāore te ngāwari o te nuinga o te wā i te tino teitei, nā te mea he kaha tōna āheinga ki te uru, ā, e whakamahia whānuitia ana mō ngā whakamātautau PCBA kua tukatukahia e OSP.
6. Te whakamātautau au teitei
Kei waenga i te 2.98 mm me te 5.0 mm te whānui o te pūwero, ā, ka taea e te iahiko whakamātautau mōrahi te eke ki te 50 A.
7. Pūtirotiro whakapā pākahiko
Ko te tikanga he mea whakamahi hei whakapai ake i te pānga whakapā, kia pai ai te pumau me te roa o te ora. Ka whakamahia hei kawe hiko i te wāhanga whakapā o te pākahiko waea pūkoro, te mokamoka kāri raraunga SIM me te wāhanga kawe hiko o te atanga rihi e whakamahia whānuitia ana.
