Machitidwe Oyang'anira Anzeru a PCBA: AOI, SPI, X-Ray, ICT & FCT

1. Chiyambi

Pamene zinthu zamagetsi zikusintha kukhala zolumikizana kwambiri komanso zovuta kwambiri, kuwunika kwa khalidwe la PCBA kumakumana ndi zovuta zambiri—makamaka pakuwunika kwa micro-pitch kwa zigawo za 0201 (0.6×0.3mm) ndi kuwunika kwa malo obisika olumikizirana mu mapaketi a BGA/CSP. IPC-A-610H, kupanga kwamakono kuyenera kusunga chiŵerengero cha zolakwika pansi pa 500 DPPM. Nkhaniyi ikufotokoza kusanthula mwadongosolo kwa machitidwe owunikira amitundu yambiri, kuphatikiza kuwongolera njira, ukadaulo woyesera mwanzeru, ndi kutsata nthawi yeniyeni.

2. Kapangidwe ka Dongosolo la Ukadaulo Woyendera

2.1 Kapangidwe ka Ma Node Oyang'anira Ogwira Ntchito Zonse

Ndondomeko yowunikira ya magawo anayi imatsimikizira kuti zinthu zonse zili bwino:

• ·Kukonzekera Koyambirira: 3D SPI (±5μm) + AOI yokonzera malo
• ·Pambuyo pa Kubwerera M'mbuyo: AOI yokhala ndi mbali ziwiri + X-Ray ya 3D (resolution ya 5μm)
• ·Kuyesa kwa Magetsi: ICT (kufalikira ≥95%) + FCT
• ·Kuyendera Komaliza: AVI + kuyesa kowononga zitsanzo

2.2 Zizindikiro Zofunikira Zogwirira Ntchito

• ·Nthawi yotsimikizira nkhani yoyamba: ≤ mphindi 15 (mosiyana ndi maola awiri mwachizolowezi)
• ·Chiŵerengero chabwino cha kuthawa kwa chilema:
• ·Kusunga deta kuti isatsatidwe: Zaka ≥10

3. Kusanthula kwa Ukadaulo Woyang'anira Pakati

3.1 Kuyerekeza kwa Ukadaulo Wowunikira Mawonekedwe

3.2 Kutha Kuyang'anira X-Ray

• ·Chithunzi cha CT Tomographic: Imazindikira chiŵerengero cha BGA chopanda kanthu IPC-7095
• ·Kukonza Nthawi Yeniyeni: Kukonza chithunzi cha ≥25fps
• ·Kulondola kwa Magulu a Zilema: >98% ndi ma algorithms othandizidwa ndi AI

4. Machitidwe Oyesera Magetsi

4.1 Kapangidwe ka Mayeso a ICT

• ·Kuyesa kocheperako: ≥0.8mm
• ·Ma voteji osiyanasiyana: 0–50V
• ·Kulondola kwa muyeso: ± 1% (kukana), ± 2% (capacitance)

4.2 Mayankho Oyesera a FCT

• ·Njira za I/O: Imathandizira njira zoposa 1000
• ·Mafupipafupi: DC–6GHz
• ·Kulondola kwa Malo Olakwika: ± 5mm

5. Dongosolo Loyang'anira Deta Yabwino

5.1 Dashboard Yowunikira Nthawi Yeniyeni

• ·Kuwunika kuchuluka kwa zinthu zomwe zapezeka pompopompo (kukonzanso nthawi iliyonse)
• ·Kusanthula kwa mapu otenthetsera zolakwika
• ·Chiwonetsero cha OEE cha zida

5.2 Njira Yotsatirira

• ·Barcode yapadera kapena UID ya bolodi lililonse
• ·Kugwirizana kwathunthu kwa deta
• ·Kuphatikiza kwa MES/QMS kwakonzeka

6. Milandu Yogwiritsira Ntchito Makampani

6.1 Zamagetsi Zamagalimoto

• ·Wovomerezeka pansi pa AEC-Q100
• ·Chiŵerengero cha kulephera kwa 0km
• ·Kutsatira malipoti a 8D

6.2 Zipangizo Zachipatala

• ·Kutsatira ISO 13485 pa zamagetsi azachipatala
• ·Kuyang'ana 100% kwa zinthu zomwe zili pachiwopsezo chachikulu
• ·Kuyesa kuyeretsa ndi kuyanjana ndi chilengedwe

7. Kusanthula Mapindu

Malinga ndi Sukulu Yasekondale 2022, kukhazikitsa njira zowunikira zanzeru komanso zamagawo ambiri kumabweretsa:

• ·30% kuwonjezeka kwa phindu loyamba
• ·40% kuchepetsa ndalama zonse zokhudzana ndi khalidwe
• ·60% madandaulo ochepa a makasitomala

8. Chidule: Nthawi Yatsopano Yoyang'anira Smart PCBA

• ·Mafelemu owunikira aukadaulo wambiri (AOI + SPI + X-Ray + ICT/FCT)
• ·Ma algorithm anzeru oweruza zolakwika omwe amayendetsedwa ndi AI
• ·Kutsata bwino kwa digito ndi kuphatikiza kwa MES

Ndi njira yokhazikika iyi, opanga amatha kukwaniritsa milingo ya Six Sigma (), kukhazikitsa miyezo yatsopano yodalirika ya PCBA yapadziko lonse lapansi.
