Te Whakatutuki i te Hanganga Kore-Hapa mā roto i ngā Pou Hangarau e Whā
I. Kaupapa Hangarau: Te Whakahaere Tika o te Whakatakotoranga o te Whakapiri Konukōre
Te Tirohanga Ahumahi: "E 60%-70% ngā hapa honohono i ahu mai i te tānga (IPC-7525 7.1.2). Ko te whakatakoto tika te huarahi tuatahi hei ārai."
Ngā Whāinga Whakahaere Tauanga
| Ahu | Ngā Whakaritenga Paerewa | Tohutoro IPC |
|---|---|---|
| Te Tika o te Oro | Te Reiti Whakawhiti > 85%, CPK ≥ 1.67 | J-STD-005 4.3.2 |
| Te Pono o te Āhua | Hekenga ≤ 10%, Kāore he hiku/hinga | IPC-SM-817 3.2.1 |
| Te Tika o te Tūnga | Wāhi Whakakore ≤ 15% o te Whānui o te Papa | IPC-A-610H 8.2.3.4 |
II. Te Arotautanga Hōhonu o ngā Pou Hangarau e Whā
1. Hoahoa Tānga: Tauira Tika Nano-tauine
- ·Te tapahi taiaho + te whakakanapa hiko (Ra ≤ 0.6μm, e tutuki ana i te Akomanga 3)
- ·Teitei piki/heke ≤ 0.08mm (hoahoa ārai-tukituki mata)
- ·Ka whakaitihia e te paninga nano SiN ngā hapa o te pōro whakarewa mā te 38%
- ·Hoahoa whakatuwheratanga moroiti mō ngā wāhanga 01005 (ōwehenga horahanga ≥ 0.71)
Rerenga Mahi Whakamana Hoahoa: PCB → DFM → Tauira → Hanganga Papatipu
2. Ngā Tawhā Tā: Mana Atamai Porowhita-Katia
| Tawhā | Awhe Paerewa | Paepae Mōrearea |
|---|---|---|
| Pēhanga o te Squeegee | 100 ± 20 karamu/mm | >150 g/mm → te whakarerekētanga o te tauira |
| Tere Wehenga | 1.5 ± 0.5 mm/s | >3 mm/s → te kōhatutanga o te urupā +250% |
| Ngā Āhuatanga Āhuarangi | 23 ± 1℃ / 50 ± 5% RH | ΔT > 3℃ → te piki me te heke o te rōrahi ±12% |
Mana Whakahaere Katia AI: Aroturuki SPI → Tauira LSTM → utu hihiri → CPK ≥ 2.0
3. Whakapiri Konukō: Te Whai Aroturuki i te Huringa Ora Katoa
- ·Rokiroki matao i te -40℃
- ·Whakamahana ā-taahiraa: 5℃ ia 2 hāora ki te pāmahana rūma
- ·Te whakaranu ā-pūwero: 1200 rpm mō te 180 hēkona
- ·Tirotiro matotoru: 850 ± 30 kcps
- ·Wā tuwhera: ≤ 72h
- ·Te herenga puranga MES mō te whai i te whai
4. Horoi Tānga: Taurangi Kore-Tohu
| Aratau Horoi | Auautanga | Tikanga Manatoko |
|---|---|---|
| Horoi Maroke + Horoi | Ia 5 PCB | Tirotiro Miroscope 50x |
| Horoi Hōhonu Whakarewa | Ia 30 meneti | Toenga Taumaha |
Ngā Paearu Para: Te kukū 50,000 rānei ngā tānga
III. Uara Kaihoko: Whakapai Kounga Ka Taea te Ine
| Ine | I mua | I muri | Horopaki |
|---|---|---|---|
| Te Huanga Paahi Tuatahi | 82% | 99.1% | QFN 0.4mm te tawhiti |
| Te Auau Hapa | 850 PPM | 62 PPM | BGA Waka (X-Ray) |
| Te utu mahi anō | $12k/marama | $0.8k/marama | Raina PCBA Hauora |
Pūtake: Papa matua o te mataaratanga atamai me te matotoru o ngā wāhanga 01005 i tutuki ai te korenga o ngā hapa pōro honohono mā te tauira paninga nano.
IV. Rohe Ahumahi: Te Wā o te Tā Atamai
Mahere Ara Hangarau
- ·2024: Te whakatauira māhanga mamati mō te tānga tauira
- ·2025: Pūnaha squeegee AI urutau
- ·2026: Mana whakahaere tauhohenga whakapiri whakarewa taumata-ngota
Te Māramatanga Ngaio
"23.7% te pikinga hua i tutuki mā te whakapai ake i te tika o te rōrahi whakapiri mai i te ±15% ki te ±8% (SMTA 2023-PT-087)."
Mā te hangarau pou-whā ka roa ake te MTBA (Mean Time Between Defects) mō ngā hapa tā ki te 1200 hāora.
