He hototahi ngā PCB Auau-Tiketike me te Tere-Tiketike ki ngā Tukanga SMT Paerewa?
Te Tūtakitanga i waenganui i te Hangarau RF me te Hanga SMT
Ko ngā PCB auau-tiketike (HF) me te tere-tiketike (HS)—e whakamahia ana i roto i ngā transceiver 5G, ngā whakawhitiwhiti kōrero amiorangi, te radar motuka, me ngā tūmau tere-tiketike—e hiahia ana kia tino tika ngā rauemi, kia whakahaere i te aukati, me te pono o te tohu.
Nō reira, ka taea te huihui pono i runga i te raina SMT paerewa?
Whakautu poto: Āe, engari me ngā whakaritenga tukanga motuhake. Anei ngā mea me mōhio koe.
Ngā Rerekētanga Matua i waenga i ngā PCB HF/HS me ngā Papa FR-4 Paerewa
| Tawhā | Papaaho HF/HS | Papaaho FR-4 Paerewa |
|---|---|---|
| Rauemi Papa | Rogers, Taconic, Megtron6 | FR-4 |
| Pūmau Whakakore Hiko (Dk) | Iti (≈2) | ~4.2–4.8 |
| Tauwehenga Whakamarara (Df) | Tino iti (hei tauira, 0.001) | Teitei ake |
| Tere Tohu | >10Gbps | |
| Mā te Hangarau | Matapo/Tanumia | Putanga-rua |
| Whakaotinga Mata | ENIG, ENEPIG, Hiriwa Rumaki | HASL |
Ngā Wero SMT Matua mō ngā PCB me ngā Otinga HF/HS
1. Te aro ki te wera
Ka whānui haere ngā paparanga PTFE i te tuaka-Z, ā, ka ngawari te motu.
- Whakamahia he kōtaha rerenga anō kua whakahaeretia (≤245°C mōrahi).
- Whakamahana āta kia kore ai e pāngia e te ru.
2. Te Whakapiko me te Āhuatanga Korekore
- Tunua ngā papa i mua i te tunu ki te 105°C mō ngā haora 2–4.
- Whakamahia ngā ārai, ngā mea pupuri rānei hei pupuri i te papatahi.
3. Hototahi ki te Whakaotinga Mata
- Whakatauritehia te whakapiri konuhono ki nga otinga ENIG/ENEPIG.
- Whakahaerehia te haumākū; tirohia ngā papa i mua i te tānga.
4. Kōwhiringa Tā me te Whakapiri
- Whakamahia te whakapiri honohono Momo 4, Momo 5 rānei.
- Whakamahia te SPI me te whakamahi i ngā tauira takahanga mō ngā teitei wāhanga kāore i te ōrite.
5. Te Parenga me te Whakatakotoranga RF
- Tāutahia te parepare i muri i te rerenga anō.
- Whakamahia he whakapiringa whiriwhiri, he epoxy kawe hiko rānei mō te hononga whenua.
Ka taea e te Raina SMT Paerewa te whakahaere i ēnei papa?
Āe—mēnā he taputapu tika tā rātou, ā, he kaimahi whakangungu hoki:
- Te rerenga anō o te hauota: Ārai i te waikura.
- Tirotiro hihi-X: He mea nui mō te BGA me te QFN.
- AOI Matatau: Ka kitea ngā nekehanga iti me ngā āputaputa.
- Rere whakamuri: Ka whakaiti i ngā āputaputa i roto i ngā papa whakamahana.
Ina he mea nui te tohungatanga huihuinga
- Ngā kōwae pūihi 5G mmWave
- Papa radar 77GHz (motuka)
- Ngā pūnaha whakahoki ngaruiti
- Ngā ara iahiko LNA/PA i roto i te rererangi
- Ngā kāri SerDes me ngā kāri whakawhiti mō te AI/ngā tūmau
He aha i whiriwhiri ai i a Rich Full Joy?
Harikoa Nui he hoa EMS pono mō ngā mākete pono-nui pēnei i te waea, te rererangi, me te motuka. Kei a mātou ēnei e tuku ana:
- SMT mō Rogers, Megtron, Teflon, me ngā ranu
- Te honohono BGA, QFN, me te mmWave IC tohunga
- DFM ā-roto mō ngā papa tere-nui
- Tautoko whakarerekētanga ritenga me te tautoko taputapu
E mārama ana mātou ki te rerekētanga i waenga i te huihuinga RF me te FR-4—ā, ka hangaia e mātou kia rite ki ō whakaritenga mahi.
