I roto i te mara o te hanga PCB (Papa Arahiko Tā), ko te tika o te keri te mea e whakatau tika ana i te mahi hiko me te tere hua o te papa arahiko. Mai i ngā maramara waea pūkoro ki ngā papa arahiko rererangi, ko te tika o ia kōhao taumata-micron he mea nui ki te angitu, ki te kore rānei o te hua. Ko ngā turanga karāhe, me ō rātou āhuatanga rauemi ahurei me ngā painga hanganga, kei te huri hei "hoa koura" o ngā taputapu keri PCB, e akiaki ana i te tika o te umanga ki tētahi taumata hou.
I. Painga Tūturu: Mā te mahi pumau ka whakatakoto i te tūāpapa mō te tika
Te pumau wera tino pai
I te wā o te keri PCB, ka taea e te wera e puta mai ana i te hurihanga tere-teitei o te mata keri te eke ki te 60-80℃. Mā te whānui o ngā rauemi whakarewa noa nā te wera ka taea te neke ngāwari i te tūranga keri. Ko te tauwehenga o te whānui wera o te karāhe he 4-8×10⁻⁶/℃ anake, arā, he 1/5 noa iho o te tauwehenga o te maitai. Ko te tikanga o tēnei, ahakoa te piki me te heke o te pāmahana o te taiao, ka taea te wareware i te rerekētanga o te turanga karāhe. I muri i te tango a tētahi kaihanga papa hiko i te turanga karāhe, ka whakaitihia te hapa o te tūranga keri mai i te ±50μm ki te ±10μm, ka whakapai ake i te ōritetanga o te mahi hiko o te papa hiko.
2. Mahi rū whenua tino kaha
Ka pā te wiri auau teitei o te mīhini keri i ngā mano hurihanga ia meneti ki te poutū o te mata keri, ka puta he rerekētanga o te whānui o te kōhao. Mā ngā āhuatanga whakamākū tūturu i roto i te karāhe ka taea e ia te mimiti i te neke atu i te 90% o ngā wiri taputapu (20-50Hz). E whakaatu ana ngā raraunga ine i muri i te tāutanga o te turanga karāhe, i heke te kaha wiri o te mata keri mai i te 15μm ki te 3μm, ā, i heke te uara Ra o te taratara o te pakitara kōhao i kerihia mā te 60%, ka tino whakaiti i ngā raruraru pakaru me te wehewehe o te pakitara kōhao.
3. Ātete kakahu roa
He mahi auau teitei te keri PCB, ā, he tino teitei ngā whakaritenga mō te ātete kakahu o te mata o te turanga. Ko te pakeke o te karāhe he 6 ki te 7, ā, e toru ngā wā o tōna ātete kakahu i te maitai noa. E toru tau te roa o te whakamahinga tonu a tētahi wheketere PCB nui i ngā turanga karāhe. He iti iho i te 0.01mm te kakahu o te mata. Ki te whakaritea ki ngā turanga whakarewa, ka rua ngā wā ka roa ake te huringa whakakapinga, ka whakaiti i te utu tiaki taputapu.
II. Whakapai ake i te Tukanga: Ka whakarei ake te hoahoa ritenga i te whai huatanga o te whakaputa
Mā te tukatuka tika me ngā hanganga auaha, ka whakanuia ake te uara o ngā turanga karāhe hou:
Tukatuka papatahi tino tika: Mā te whakamahi i te hangarau whakahaere tau hononga tuaka-rima, ka whakahaerehia te papatahi o te turanga i roto i te ±0.5μm/m, ka whakarato i te mata tohutoro tino papatahi mō ngā taputapu keri, me te whakarite kia iti iho i te 0.01° te hapa poutū o te mata keri.
Hanganga mimiti ru honikoma: Ko te hoahoa honikoma o roto e hanga ana i tētahi kōhao motuhake, e tutuki ai te whakaiti i te kaha wiri maha-taumata, ā, he tino pai mō te tukatuka kōhao moroiti o te 0.1mm, iti iho rānei.
Ngā hongere whakamatao wai kua whakauruhia: Mō ngā taputapu keri kaha-teitei, kua tāutahia he pūnaha whakamatao wai hongere-iti kua hangaia hei whakahaere i te rerekētanga pāmahana i runga i te mata turanga i roto i te ±0.5℃, ka whakakorea katoatia te mōrearea o te whakarerekētanga wera.
Tahora mokamoka-T ritenga: Ka whakaritea te mokowā me te tika o te mokamoka-T (±0.01mm) kia rite ki te tauira mīhini keri kia tere ai te whakanoho me te tāutanga o ngā taputapu, kia whakaitihia ai te wā whakatūnga o tētahi taputapu kotahi mā te 70%.
III. Ngā Taunakitanga Ahumahi: Ngā Whakapainga Whai Hua e Kitea ana
Whai muri i te whakaurunga mai o ngā turanga karāhe e tētahi kaihanga PCB matua, i tino pai ake ngā raraunga whakaputa o āna raraunga:
Heoi anō, kua āwhina te turanga o te karāhe ki ngā umanga ki te wawahi i ngā arai hangarau, ki te whakahaere angitu i ngā ota mō ngā kōhao moroiti he 0.2mm te rahi, iti iho rānei, me te whakatuwhera i ngā mākete uara tāpiri nui.
Iv. Ngā Painga Tauwhiro: He kōwhiringa pai mō te hanga matomato
He kōhatu tūturu te karāneti, kāore he paninga matū, ā, kāore he tukunga VOC, e tutuki ana i ngā paerewa tiaki taiao RoHS. Nā tōna roa o te mahi ka whakaiti i te auau o te whakakapinga taputapu, ka whakaiti i te whakapaunga rauemi me ngā tukunga waro. E whakaatu ana te tātaitanga a tētahi tari tiaki taiao mā te whakamahi i tētahi turanga karāneti mō tētahi taputapu keri PCB kotahi ka taea te whakaiti i ngā tukunga waro mā te 3 tana puta noa i tōna huringa ora katoa, he mea e rite ana ki te ia o te huringa matomato o te umanga hanga.
Mai i te whakahaere tika taumata-micron ki te arotautanga utu tukanga katoa, kei te whakahouhia e ngā turanga karāhe ngā paerewa o ngā tukanga keri PCB me ō rātou painga mahi kore e taea te whakakapi. I tēnei wā o te hiahia nui mō ngā maramara 5G me te AI, ko te whiriwhiri i tētahi turanga karāhe ehara i te mea he haumitanga ki te kounga hua anake engari he taahiraa nui hoki ki te hopu i te taumata hangarau teitei.
