PCB Hononga Matotoru Teitei o Ngā Apa Katoa
TE ARĀHI TAKE O TE HDI
Ko te HDI he whakarāpopototanga mō te High Density Interconnector, he momo hangarau hanga PCB, e whakamahi ana i te hangarau matapo iti/huna hei whakatutuki i te matotoru o te tohatoha raina teitei. Ka taea e ia te whakatutuki i ngā rahinga iti ake, te mahi teitei ake me te utu iti iho. Ko te HDI PCB te whai a ngā kaihoahoa, e whanake tonu ana ki te matotoru teitei me te tika. Ko te mea e kiia nei ko te "teitei" ehara i te mea ka whakapai ake i te mahi a te mīhini, engari ka whakaitihia hoki te rahi o te mīhini. Ka taea e te hangarau High Density Integration (HDI) te whakaiti i te hoahoa hua mutunga, me te whakatutuki i ngā paerewa teitei ake o te mahi hiko me te whai hua.
Ko te PCB HDI he tikanga kei roto ko te arai keri taiaho mā te arai keri miihini me te arai keri miihini mā te arai keri. Ko te hangarau o te kawe i waenga i ngā paparanga o roto me o waho ka tutukihia mā roto i ngā tukanga pēnei i te arai tanumia, te arai matapo, ngā kōhao whakarārangi, ngā kōhao whakarara, te arai whakawhiti/tāpuke, ngā kōhao mā te arai, te whakakikorua hiko mā te arai whakakī, te waea pai he wāhi iti me ngā kōhao moroiti i roto i te kōpae, me ētahi atu.
He maha ngā momo PCB HDI: 1 paparanga, 2 paparanga, 3 paparanga, 4 paparanga me te hononga o tētahi paparanga.
● Hanganga o te HDI paparanga kotahi: 1+N+1 (pēhia kia rua ngā wā, kerihia mā te laser kia kotahi te wā).
● Hanganga o te HDI paparua-rua: 2+N+2 (pēhia kia toru ngā wā, kerihia mā te laser kia rua ngā wā).
● Hanganga o te HDI paparanga-3: 3+N+3 (pēhia kia 4 ngā wā, kerihia mā te laser kia 3 ngā wā).
● Hanganga o te HDI paparanga 4: 4+N+4 (pēhia kia 5 ngā wā, kerihia mā te laser kia 4 ngā wā).
Mai i ngā hanganga o runga ake nei, ka taea te whakatau ko te keri taiaho kotahi he HDI paparanga kotahi, ko te keri rua he HDI paparanga rua, ā, pērā tonu. Ka taea e tētahi hononga paparanga te tīmata i te keri taiaho mai i te papa matua. Ara, ko te mea me keri taiaho i mua i te pēhi ko te HDI paparanga kotahi.
Kaupapa Hoahoa o te HDI
1. Ina tūtaki tātou ki tētahi hoahoa he kōhao kei roto i te rohe BGA o tētahi PCB maha-paparanga, engari nā te iti o te wāhi, me whakamahi tātou i ngā papa BGA tino iti me ngā kōhao tino iti hei whakatutuki i te urunga ki te papa katoa, me pēhea tā tātou hanga? Inaianei ka hiahia mātou ki te whakauru i te PCB tino tika HDI e whakahuatia pinepine ana i roto i ngā PCB e whai ake nei.
Ka pāngia te keri PCB tuku iho e te taputapu keri. Ina tae te rahi o te kōhao keri ki te 0.15mm, kua tino teitei te utu, ā, he uaua ki te whakapai ake. Heoi, nā te iti o te wāhi, ina taea anake te whakamahi i te rahi kōhao 0.1mm, me whai whakaaro hoahoa HDI.
2. Kāore te keri o te HDI PCB e whakawhirinaki ana ki te keri miihini tuku iho, engari e whakamahi ana i te hangarau keri taiaho (e mōhiotia ana ko te papa taiaho). Ko te rahi o te poka keri o te HDI he 3-5mil (0.076-0.127mm), ko te whānui o te raina he 3-4mil (0.076-0.10mm), ka taea te whakaiti i te rahi o ngā papa whakapiri, kia nui ake ai te tohatoha raina mō ia wāhanga horahanga, ka hua ake he hononga kiato teitei.
Nā te putanga mai o te hangarau HDI kua urutau ki te whanaketanga o te umanga PCB, ā, kua whakatairangahia hoki, kia taea ai te whakarite i ngā BGA, QFP, me ētahi atu kia matotoru ake ki runga i te PCB HDI. I tēnei wā, kua whānuitia te whakamahinga o te hangarau HDI, ā, i roto i ēnei ko te HDI paparanga kotahi kua whānuitia te whakamahinga i roto i te hanga PCB me te 0.5pitch BGA. Ko te whanaketanga o te hangarau HDI kei te akiaki i te whanaketanga o te hangarau maramara, ā, koinei anō te mea e akiaki ana i te whakapainga me te ahunga whakamua o te hangarau HDI.
I ēnei rā, kua whānuitia te whakamahi a ngā kaihoahoa i ngā maramara BGA 0.5-pitch, ā, kua huri haere ngā hononga honohono o te BGA mai i te āhua poka i waenganui, i te āhua whenua rānei ki te āhua me te tohu tāuru me te tohu whakaputa kei waenganui e hiahia ana ki te waea.
3. Ko te tikanga hanga o te papa PCB HDI he tikanga whakarārangi. Ka nui ake te whakarārangi, ka teitei ake te taumata hangarau o te papa. Ko te papa PCB HDI noa ka whakarārangihia kotahi te wā, ko te HDI paparanga teitei ia ka whakamahi i te hangarau whakarārangi e rua, neke atu rānei, me ngā hangarau PCB matatau pēnei i te whakarārangi poka, te whakakī poka mā te whakakikorua hiko me te keri taiaho tika, me ētahi atu.
He pai te whakamahi i te PCB HDI mō te hangarau huihuinga matatau, ā, he teitei ake te mahi hiko me te tika o te tohu i te PCB tuku iho. Hei tāpiri, he pai ake ngā whakapainga a te HDI ki te wawaotanga auau reo irirangi, te wawaotanga ngaru hikohiko, te tukunga hiko me te kawe wera, me ētahi atu.
