Kuyika kwa SMT Kolondola Kwambiri kwa Msonkhano Wodalirika wa PCBA

1. Chiyambi

Mu kupanga zamagetsi zamakono, kuyika zigawo ndi gawo lofunika kwambiri la njira ya SMT (Surface Mount Technology), zomwe zimakhudza mwachindunji kudalirika ndi magwiridwe antchito a PCBA (Printed Circuit Board Assembly). Pamene zipangizo zamagetsi zimakhala zazing'ono komanso zolumikizana bwino, zovuta pakuyika zimawonjezeka kwambiri - kuyambira pakugwira ntchito ndi zigawo zazing'ono kwambiri za 01005 (0.4×0.2mm) mpaka kukwaniritsa zofunikira zodalirika za mapaketi ovuta monga BGA ndi QFN (IPC-7351B, 2014).

2. Zinthu Zaukadaulo Zapakati pa Njira Zoyikira

2.1 Kutola ndi Kuyika Kolondola Kwambiri

• ·Kutenga Mwanzeru: Amagwiritsa ntchito manja a robotic olimba kwambiri komanso ma nozzle osinthika a vacuum kuti azitha kulamulira mphamvu yonyamula katundu ndikupewa kuwonongeka kwa zigawo zake (Juki, 2023).
• ·Kulinganiza kwa Mawonekedwe Anzeru: Amagwiritsa ntchito makina owonera okhala ndi mawonekedwe apamwamba (monga Fuji NXT's 3D vision) kuti agwirizane bwino zinthu ndi ±15μm molondola (Fuji, 2021).
• ·Kulipira Kowonjezera Mphamvu: Amasintha kuthamanga kwa Z-axis kutengera kupezeka kwa PCB warpage kuti atsimikizire kulumikizana koyenera kwa solder paste (Panasonic NPM Series Technical Manual).

2.2 Kukonza Njira ndi Kuyang'anira Deta

• ·Kukonza Pulogalamu Yokwera: Imagwiritsa ntchito ma algorithms anzeru okonza ma panel kuti ifupikitse njira zoyendera mitu ndikuwonjezera magwiridwe antchito (Pepala Loyera la Yamaha YSM20R).
• ·Deta Yosungiramo Zinthu: Imagwirizanitsa magawo okhazikika a IPC-7351 kuti agwiritse ntchito njira zolondola pokonza 0201, BGA, ndi ma phukusi ena (SMTnet, 2020).
• ·Kuphatikiza kwa MES System: Kutsimikizira kutsimikizika kwa BOM ndi kupewa zolakwika zokha ngati zinthu sizikugwirizana kapena kuyika kumbuyo.

3. Zipangizo Zofunika ndi Kuwongolera Njira

3.1 Kuyang'anira Ma Nozzle ndi Ma Feeder

• ·Kuyang'anira Mkhalidwe wa Nozzle: Kuzindikira vacuum nthawi yeniyeni (malo olowera ≥ -80kPa) kumayambitsa kuyeretsa kapena kusintha kokha pakapezeka cholakwika (Juki, 2023).
• ·Kupewa Zolakwika za Wodyetsa: Kutsata ma code a RFID/QR kumatsimikizira kuti zinthu zitha kutsatidwa bwino komanso kuti zinthu zizigwiritsidwa ntchito nthawi zonse kuti zisamakhale ndi vuto la kutopa komanso kudyetsa anthu opanda kanthu (NEPCON Asia, 2023).

3.2 Kudalirika kwa Wodyetsa

• ·Kusamalira Kodzitetezera: Kuyeza zida zodyetsera chakudya nthawi iliyonse 2 miliyoni kumachepetsa kupotoka kwa makina.
• ·Chenjezo la Zovuta: Masensa ogwedera amazindikira kuyenda kosazolowereka pasadakhale, zomwe zimathandiza kuzimitsa ndi kukonza zinthu mwachangu.

4. Kufunika kwa Makasitomala ndi Mapulogalamu Ogwiritsa Ntchito Makampani

• ·Zamagetsi Zamagalimoto: Imakwaniritsa miyezo ya chitetezo yogwira ntchito ya ISO 26262 ya ma module a ECU omwe amakhala odalirika kwa nthawi yayitali.
• ·Zipangizo Zachipatala: Zimagwirizana ndi miyezo ya IEC 60601, kuchepetsa zoopsa zomwe zingachitike chifukwa cha kutayika kwa malo.
• ·Zipangizo Zolankhulirana: Imathandizira kuyika kwa ≤0.3mm kwa ma module a 5G mmWave ndi ma board olumikizirana othamanga kwambiri.

5. Kuyerekeza Magwiridwe Antchito a Zipangizo Zazikulu

(Chitsime: Lipoti la Mayeso la NEPCON Asia 2023)

6. Chidule: Chinsinsi cha Kuyika Kodalirika Kwambiri

• ·Zipangizo Zolondola: Kulipira kwa ma axis ambiri komanso kulondola kwa ma micron.
• ·Machitidwe Olamulira Anzeru: Kusamalira nozzle/feeder ya moyo wonse.
• ·Deta Yokhazikika: Kuphatikiza laibulale ya zigawo za IPC + kutsata kwa MES.

Mwa kuchita kuwongolera mwadongosolo pa ndondomeko yonse, opanga amatha kupeza phindu loyamba la ≥99.95% — muyezo mumakampani amagetsi — kupatsa makasitomala ntchito yabwino komanso yothandiza popanga zinthu.
