1. Kev Taw Qhia
Hauv kev tsim khoom siv hluav taws xob niaj hnub no, kev tso cov khoom yog ib theem tseem ceeb ntawm SMT (Surface Mount Technology) cov txheej txheem, uas cuam tshuam ncaj qha rau kev ntseeg tau thiab kev ua tau zoo ntawm PCBA (Printed Circuit Board Assembly). Thaum cov khoom siv hluav taws xob ua kom me dua thiab sib xyaw ua ke, cov teeb meem hauv kev tso khoom nce ntxiv ntau - los ntawm kev tuav cov khoom me me 01005 (0.4 × 0.2 hli) mus rau kev ua kom tau raws li qhov xav tau ntawm cov pob khoom nyuaj xws li BGA thiab QFN (IPC-7351B, 2014).
2. Cov Ntsiab Lus Tseem Ceeb ntawm Cov Txheej Txheem Mounting
2.1 Kev Txais thiab Tso Chaw Uas Muaj Kev Ntsuas Siab
- ·Kev Ntsuas Precision: Siv cov caj npab robotic uas muaj zog heev thiab cov qhov nqus tsev uas hloov tau yooj yim los tswj lub zog rub thiab zam kev puas tsuaj rau cov khoom (Juki, 2023).
- ·Kev Sib Txuas Lus Pom Kev Ntse: Siv cov tshuab kho qhov muag siab (piv txwv li, Fuji NXT's 3D vision) los sib dhos cov khoom sib dhos nrog qhov tseeb ± 15μm (Fuji, 2021).
- ·Kev Them Nyiaj Dynamic Mounting: Kho qhov siab Z-axis raws li PCB warpage nrhiav kom paub tseeb tias kev sib cuag ntawm cov tshuaj nplaum solder zoo (Panasonic NPM Series Technical Manual).
2.2 Kev Txhim Kho Cov Txheej Txheem thiab Kev Tswj Xyuas Cov Ntaub Ntawv
- ·Kev Txhim Kho Qhov Kev Pabcuam Mounting: Siv cov algorithms optimization ntse los txo cov kev mus los ntawm lub taub hau thiab ua kom qhov chaw ua haujlwm zoo dua (Yamaha YSM20R Daim Ntawv Dawb).
- ·Cov Ntaub Ntawv Cheebtsam: Kev sib xyaw ua ke cov qauv txheem IPC-7351 rau cov tswv yim meej hauv kev tswj hwm 0201, BGA, thiab lwm yam pob khoom (SMTnet, 2020).
- ·Kev Sib Koom Tes ntawm MES System: Xyuas kom meej tias BOM raug lees paub thiab tiv thaiv qhov yuam kev tsis siv neeg rau cov khoom tsis sib xws lossis rov qab mounting.
3. Cov Khoom Siv Tseem Ceeb thiab Kev Tswj Xyuas Txheej Txheem
3.1 Kev Tswj Xyuas Nozzle thiab Feeder
- ·Kev Saib Xyuas Qhov Mob Nozzle: Kev ntsuas lub tshuab nqus tsev tiag tiag (qhov txwv ≥ -80kPa) ua rau muaj kev ntxuav lossis hloov pauv tsis siv neeg thaum pom qhov txhaum (Juki, 2023).
- ·Kev Tiv Thaiv Qhov Yuam Kev ntawm Feeder: Kev taug qab RFID/QR code ua kom ntseeg tau tias muaj kev taug qab thiab kev tswj hwm lub neej kom tsis txhob muaj daim kab xev daig thiab pub khoom khoob (NEPCON Asia, 2023).
3.2 Kev Ntseeg Tau ntawm Feeder
- ·Kev Txij Nkawm Tiv Thaiv: Kev kho qhov chaw pub khoom noj txhua 2 lab lub voj voog txo qhov kev hloov pauv ntawm cov khoom siv.
- ·Ceeb Toom Txog Qhov Txawv Txawv: Cov cuab yeej ntsuas kev co ntes tau qhov kev txav tsis tu ncua ua ntej, ua rau muaj kev kaw thiab kev saib xyuas ua ntej.
4. Tus nqi ntawm cov neeg siv khoom thiab cov ntawv thov kev lag luam
- ·Cov Khoom Siv Hluav Taws Xob Hauv Tsheb: Ua tau raws li ISO 26262 cov qauv kev nyab xeeb rau ECU modules nrog kev ntseeg siab ntev.
- ·Cov Khoom Siv Kho Mob: Ua raws li IEC 60601 tus qauv, txo qis kev pheej hmoo ntawm kev ua tsis tiav vim yog qhov chaw tsis raug.
- ·Cov Khoom Siv Sib Txuas Lus: Txhawb nqa ≤0.3mm suab mounting rau 5G mmWave modules thiab high-speed kev sib txuas lus boards.
5. Kev Sib Piv Kev Ua Haujlwm ntawm Cov Khoom Siv Tseem Ceeb
| Qauv Khoom Siv | Qhov Chaw Tseeb (μm) | Ceev (CPH) | Yam Tsawg Kawg Nkaus Cheebtsam |
|---|---|---|---|
| Yamaha YSM20R | ±25 | 96,000 | 01005 |
| JUKI RS-1R | ±30 | 85,000 | 0201 |
| Panasonic NPM-W2 | ±20 | 108,000 | 01005 |

6. Cov Lus Qhia Luv: Cov Yuam Sij Rau Kev Txhim Kho Kom Muaj Kev Ntseeg Siab
- ·Cov Khoom Siv Ua Kom Tseeb: Kev them nyiaj ntau-axis thiab qhov tseeb ntawm micron.
- ·Cov Txheej Txheem Tswj Xyuas Ntse: Kev tswj hwm lub nozzle/feeder tag nrho lub neej.
- ·Cov Ntaub Ntawv Txheem: Kev koom ua ke ntawm IPC Cheebtsam Tsev Qiv Ntawv + MES traceability.
Los ntawm kev ua tiav kev tswj hwm thoob plaws hauv cov txheej txheem tag nrho, cov chaw tsim khoom tuaj yeem ua tiav thawj zaug dhau ntawm ≥99.95% - tus qauv hauv kev lag luam hluav taws xob - xa cov neeg siv khoom zoo sib xws thiab kev ua haujlwm tsim khoom zoo.
