Kukwaniritsa Kupanga Kopanda Zolakwika Kudzera Mu Zipilala Zinayi Zaukadaulo
I. Chigawo Chaukadaulo: Kuwongolera Mwanzeru kwa Kuyika Ma Solder Paste
Chidziwitso cha Makampani: "Zolakwika za 60%-70% zosungunula zimachokera ku kusindikiza (IPC-7525 7.1.2). Kuyika bwino zinthu ndiye njira yoyamba yodzitetezera."
Zolinga Zowongolera Kuchuluka
| Kukula | Zofunikira Zachikhalidwe | Chikalata cha IPC |
|---|---|---|
| Kulondola kwa Voliyumu | Chiŵerengero Chosamutsira > 85%, CPK ≥ 1.67 | J-STD-005 4.3.2 |
| Umphumphu wa Mawonekedwe | Kutsika ≤ 10%, Palibe Kutaya/Kugwa | IPC-SM-817 3.2.1 |
| Kulondola kwa Malo | Kuchepetsa ≤ 15% ya Kukula kwa Pad | IPC-A-610H 8.2.3.4 |
II. Kukonza Kwambiri Zipilala Zinayi Zaukadaulo
1. Kapangidwe ka Stencil: Chikhomo Cholondola Kwambiri cha Nano-scale
- ·Kudula ndi laser + kupukuta ndi magetsi (Ra ≤ 0.6μm, kutsatira kalasi 3)
- ·Kutalika kwa sitepe-mmwamba/pansi ≤ 0.08mm (kapangidwe kotsutsana ndi kugundana kwa tsamba)
- ·SiN nano-coating imachepetsa zolakwika za mpira wa solder ndi 38%
- ·Kapangidwe ka micro aperture ka zigawo za 01005 (chiŵerengero cha dera ≥ 0.71)
Kayendedwe ka Ntchito Yotsimikizira Kapangidwe: PCB → DFM → Chitsanzo → Kupanga Zinthu Zambiri
2. Ma Parameter Osindikizira: Kulamulira Kwanzeru Kotsekedwa
| Chizindikiro | Mtundu Wokhazikika | Malo Olowera Pangozi |
|---|---|---|
| Kupanikizika kwa Squeegee | 100 ± 20 g/mm | >150 g/mm → kusintha kwa stencil |
| Liwiro Lopatukana | 1.5 ± 0.5 mm/s | >3 mm/s → kuyika miyala pamanda +250% |
| Mikhalidwe Yozungulira | 23 ± 1℃ / 50 ± 5% RH | ΔT > 3℃ → kusinthasintha kwa voliyumu ± 12% |
Kulamulira kwa AI Closed-loop: Kuyang'anira SPI → LSTM model → dynamic compensation → CPK ≥ 2.0
3. Solder Paste: Kutsata Kwathunthu kwa Moyo
- ·Kusunga kozizira pa -40℃
- ·Kutentha pang'onopang'ono: 5℃ maola awiri aliwonse kutentha kwa chipinda
- ·Kusakaniza kwa centrifugal: 1200 rpm kwa 180s
- ·Kuwunika kukhuthala: 850 ± 30 kcps
- ·Nthawi Yotsegulira: ≤ 72h
- ·Kumangirira gulu la MES kuti lizitha kutsatiridwa
4. Kuyeretsa Stencil: Chitsimikizo cha Zero-residue
| Njira Yoyeretsera | Kuchuluka kwa nthawi | Njira Yotsimikizira |
|---|---|---|
| Pukutani Youma + Vacuum | Ma PCB asanu aliwonse | Kuyang'anira Maikolosikopu kwa 50x |
| Chosungunulira Chozama Choyeretsera | Mphindi 30 zilizonse | Zotsalira za Gravimetric |
Zofunikira Zochepa: Kupsinjika 50,000 zosindikizidwa
III. Mtengo wa Makasitomala: Kukweza Ubwino Woyenera Kuwerengedwa
| Chiyerekezo | Pamaso | Pambuyo pake | Chitsanzo |
|---|---|---|---|
| Kupereka Koyamba | 82% | 99.1% | QFN ya 0.4mm |
| Chiŵerengero Chabwino cha Zolakwika | 850 PPM | 62 PPM | Magalimoto BGA (X-Ray) |
| Mtengo Wokonzanso | $12k pamwezi | $0.8k pamwezi | Mzere wa PCBA Wachipatala |
Chikwama: Bolodi yayikulu ya Smartwatch yokhala ndi kuchuluka kwa zigawo 01005 sinapeze vuto lililonse la mpira pogwiritsa ntchito stencil yokhala ndi nano-coated
IV. Malire a Makampani: Nthawi ya Kusindikiza Mwanzeru
Mapu a Ukadaulo
- ·2024: Kuyeserera kwa mapasa a digito posindikiza stencil
- ·2025: Dongosolo losinthira la AI
- ·2026: Kulamulira kwa reactivity ya solder phala pamlingo wa mamolekyulu
Chidziwitso cha Akatswiri
"Kupeza phindu la 23.7% komwe kwapezeka powonjezera kulondola kwa kuchuluka kwa phala kuchokera pa ±15% mpaka ±8% (SMTA 2023-PT-087).
Ukadaulo wa zipilala zinayi umakulitsa vuto losindikiza MTBA (Mean Time Between Defects) mpaka maola 1200."
