I te whānui haere o te whakamahinga o ngā rauemi tere-teitei i roto i ngā whakawhitiwhitinga 5G, ngā hikohiko motuka, me te rorohiko mahi-teitei, kei te anga whakamua ngā kaihanga PCB ki ngā tono mō te tika, te whai hua, me te pono o te keri. Ko ngā āhuatanga ahurei o ngā rauemi tere-teitei—te iti o te ngaronga tuku, te ātete wera nui, me te kaha miihini—e whakarei ake ana i te mahi PCB engari e whakauru ana hoki i ngā wero nui mō ngā tukanga keri. I roto i ēnei, kua noho te ICD (Inner Connection Defects) hei āhuatanga nui e pā ana ki te hua me te pono o te PCB.

Ngā Wero Matua i roto i te Keri PCB Tere-Tiketike

• Ngā hapa ICD: I te wā o te huihuinga SMT me te rerenga anō i te pāmahana teitei, ka puta pea te wehenga o te kapia, ngā ngatata rānei, ka hua ake he hononga ngoikore ki te paparanga o roto.
• Te Whakaiti i te Ora o te Mata Wiri: Ka tere ake te pakaru o te taputapu nā te waku nui me te ahotea wera i te wā wiri, ka whakaitihia te ora o te wiri mā te neke atu i te 50%.
• Te Pai o te Tukatuka: Me whakaiti te tere o ngā mata keri tuku iho i te neke atu i te 20% i te wā e tukatuka ana i ngā rauemi tere-rahi, ka whakawhāiti i te hua katoa.

Te Hoahoa Mata Wiri me te Arotautanga Paninga

• Hoahoa Mata Wiri: E whakaatu ana ngā rangahau ko ngā wiri pūtoru kotahi-rua mata-rua USF me ngā wiri pania-SHC te mea tino pai mō te wiri rauemi tere-rahi. Ka āwhina te hoahoa USF ki te whakaiti i te hanganga ICD, ā, ka whakarei ake ngā paninga SHC i te ātete ki te kakahu me te roa o te ora o te taputapu.
• Ngā Painga o te Paninga: Ki te whakaritea ki ngā wiri paerewa, ka roa ake te ora o ngā taputapu kua pania ki te SHC mā te neke atu i te 30% me te pupuri tonu i te kounga o ngā kōhao, he mea tino pai mō te hanga PCB nui-rahi, tere-nui.

Arotautanga Tawhā Tukanga

E whakaatu ana ngā whakamātautau whakatairite:

• Mā te whakarerekētanga tika o te tere whāngai me te tere tapahi ka whakaitihia te hanganga o ngā tataramoa me te kino ki te pakitara o ngā kōhao.
• I runga i ngā papa tere-rahi 0.25 mm, i mau tonu te kounga o ngā wiri pania ki te SHC mō ngā patunga neke atu i te 600, engari ko ngā wiri paerewa i whakaatu i te hekenga nui i muri i ngā patunga 400.

Hei whakatika i ngā wero o te keri rauemi PCB tere-teitei, he mea nui te hoahoa keri kua arotauhia, ngā hangarau paninga matatau, me ngā tawhā tukanga kua whakatikatikaina. Hei kaihanga PCB me PCBA ngaio, ehara i te mea ka tukuna e mātou ngā kaha keri tino tika engari ka whakaratohia hoki e mātou ngā otinga arotau tukanga pono me te whai hua kua whakaritea kia rite ki ngā hiahia o ā mātou kiritaki.
