MaPCB Anomhanya Zvikuru uye Anomhanya Zvikuru Anoenderana Nemaitiro Akajairwa eSMT Here?
Kusawirirana Pakati PeRF Engineering neSMT Manufacturing
MaPCB eHigh-frequency (HF) uye High-speed (HS) — anoshandiswa mumatransceiver e5G, kutaurirana kwesatellite, radar yemotokari, uye maseva ehigh-speed — anoda kunyatsojeka kwezvinhu, kudzora impedance, uye kuvimbika kwemasaini.
Saka, dzinogona kuunganidzwa zvakavimbika pamutsetse weSMT wakajairika here?
Mhinduro pfupi: Ehe, asi nemaitiro chaiwo ekugadzirisa. Hezvino zvaunofanira kuziva.
Kusiyana Kwakakosha Pakati peHF/HS PCBs neStandard FR-4 Boards
| Paramita | HF/HS PCB | PCB yakajairika yeFR-4 |
|---|---|---|
| Zvinhu zvepasi pevhu | Rogers, Taconic, Megtron6 | FR-4 |
| Dielectric Constant (Dk) | Yakaderera (≈2) | ~4.2–4.8 |
| Chinhu Chinoparadza (Df) | Zvakaderera zvakanyanya (semuenzaniso, 0.001) | Yepamusoro |
| Kumhanya kweChiratidzo | >10Gbps | |
| Kuburikidza neTekinoroji | Bofu/Kuvigwa | Mugomba unopinda nepakati |
| Kupedzisa Kwepamusoro | ENIG, ENEPIG, Kunyudza Sirivha | HASL |
Matambudziko Epamusoro eSMT eHF/HS PCBs & Solutions
1. Kunzwa kwekupisa
Ma laminate akavakirwa paPTFE anokura achitevedza Z-axis uye anotsemuka zviri nyore.
- Shandisa purogiramu yekudzokorodza mvura yakadzorwa (≤245°C max).
- Kupisa zvishoma nezvishoma kuti usavhunduke.
2. Warpage uye Dimensional Instability
- Bika mabhodhi pa105°C kwemaawa maviri kusvika mana.
- Shandisa zvinhu kana zvinhu zvinotakura kuti zvirambe zvakati sandara.
3. Kuenderana Kwekupedzisa Kwepamusoro
- Match solder paste kune ENIG/ENEPIG inopera.
- Dzora hunyoro; tarisa mapedhi usati wadhinda.
4. Sarudzo yeStencil & Namatidza
- Shandisa paste yemhando yechina kana yeshanu.
- Ita SPI uye shandisa mastencil ematanho pakukwirira kusina kuenzana kwezvikamu.
5. Kudzivirira & Kudzika kweRF
- Isa chidziviriro mushure mekubudazve kwemvura.
- Shandisa soldering yakasarudzwa kana epoxy inofambisa mvura kuti uise pasi.
Mutsetse weSMT Wakajairika Ungagona Kubata Mabhodhi Aya Here?
Ehe—kana uine maturusi akakodzera uye vashandi vakadzidziswa:
- Kuyererazve kweNitrogen: Inodzivirira oxidation.
- Kuongorora X-ray: Zvakakosha paBGA neQFN.
- AOI Yepamusoro: Inoona mafambiro madiki uye maburi asina chinhu.
- Kuyererazve kwevacuum: Inoderedza maburi ari muma thermal pads.
Kana Unyanzvi Hwekugadzira Huchikosha Chaizvo
- Mamodule eantenna e5G mmWave
- Mabhodhi eradar e77GHz (mota)
- Masisitimu ekugadzirisa ma microwave
- Maseketi eLNA/PA mundege
- Makadhi eSerDes & transceiver eAI/maseva
Sei Uchifanira Kusarudza Mufaro Wakazara?
Mufaro Wakazara Wakapfuma ishamwari inovimbwa nayo yeEMS yemisika inovimbika zvikuru yakadai senharembozha, ndege, uye mota. Tinopa:
- SMT yeRogers, Megtron, Teflon, uye hybrids
- Nyanzvi yeBGA, QFN, uye mmWave IC soldering
- DFM yemukati yemabhodhi anomhanya zvakanyanya
- Rutsigiro rwekugadzirisazve zvinhu uye zvekugadzirisa zvinhu
Tinonzwisisa musiyano uripo pakati peRF neFR-4 assembly—uye tinogadzira zvinoenderana nezvinodiwa nemashandiro enyu.
