PCB ( Printed Circuit Poari ), hoki e mohiotia ana te poari taiawhio tāngia, ko te wae nui hiko, he tautoko hoki ngā wāhanga hiko, me te kawe hoki hononga hiko o ngā wāhanga hiko. No te mea kua meinga reira e te tā hiko, huaina reira ko te "tā" poari ara iahiko.

taumahi

I muri i te taputapu hiko Tiwihana te poari tāngia, e tika ana ki te ōritetanga o te poari tā taua, kua karohia te waea ā-, a taea te kōkuhu i te wae hiko aunoa ranei eke, soldered aunoa, me aunoa kitea ki te whakarite i te kounga o te taputapu hiko . Whakanuia mahi hua, whakaiti i ngā utu, me te whakahaere tiaki.

whanaketanga

Kua tipu papa tāngia i ngā papa kotahi ki rua-tapa, maha-apa, me te ngāwari, me te mau tonu ano o ratou ngā mahi. Nā ki te whanaketanga tonu o te pū tiketike, kiato tiketike, me te tika tiketike, kua heke te rōrahi, heke te utu e, ka pai ake te mahi e, na e pupuritia tonu te poari tāngia he ivi kaha i roto i te whanaketanga o te taputapu hiko i roto i te heke mai .

Classification

E ai ki te maha o ngā papa, e tahuri iho te poari ara iahiko ki toru ngā wāhanga matua: rōpū kotahi, rōpū rua, me maha-apa poari ara iahiko.

Ko te tuatahi ko te rōpū kotahi. I runga i te PCB taketake nuinga, e hāngai nga wahi i tetahi taha, me te e hāngai nga waea i runga i te tahi atu taha. No te mea anake puta te waea i tetahi taha, i huaina ai ko te poari taiawhio kotahi-taha.

awhi Takitahi e faingofua ki te hanga me te iti i roto i te utu te tikanga, engari ko te rerekētanga, ko te e kore e taea te tono ratou ki ngā hua e te hunga uaua rawa.

Ko te rōpū rua ko te toronga o te rōpū kotahi. A, no te kore e taea e te whakatau i te waea paparanga kotahi nga hiahia o te hua hiko, whakamahia te rōpū rua te.

taha e rua i tohu parahi-kakahuria, a taea te whakamahi i te vias ki te tahuri i runga i te rārangi i waenganui i te papa e rua ki te hanga i te hononga whatunga e hiahiatia ana.

e pā ana te poari maha-apa ki te poari tāngia he toru, neke atu rānei ngā papa o te apa tauira conductive me te rauemi whakaurua therebetween te tuuraa i, me nga tauira conductive therebetween, e toaati rite hiahiatia.

Maha-apa papa iahiko ko te hua o te whanaketanga o te hangarau mōhiohio hiko i roto i te ahunga o te tere tiketike, maha-mahi, kaha nui, rōrahi iti, te hahore, me te taimaha marama.

E ai ki nga āhuatanga, kua wehea te poari ara iahiko ki te poari ngohengohe (FPC), he poari pakeke (PCB), me te poari ngohengohe me te pakeke (FPCB).
