Kodi Zifukwa Zotani za Chip Component Cacking?

Popanga PCBAmakina a SMT, kuwonongeka kwa zigawo za chip ndizofala mu multilayer chip capacitor (MLCC), yomwe imayambitsa makamaka chifukwa cha kutentha kwa kutentha ndi kupanikizika kwa makina.

1. ZINTHU ZOKHALA za MLCC capacitors ndi zofooka kwambiri.Nthawi zambiri, MLCC imapangidwa ndi ma multilayer ceramic capacitors, motero imakhala ndi mphamvu zochepa ndipo ndiyosavuta kukhudzidwa ndi kutentha ndi mphamvu yamakina, makamaka pakuwotchera mafunde.

2. Panthawi ya SMT, kutalika kwa z-axis yamakina opangira ndi kukonzazimatsimikiziridwa ndi makulidwe a zigawo za chip, osati ndi mphamvu yamagetsi, makamaka kwa makina ena a SMT omwe alibe z-axis yofewa yotsetsereka ntchito, kotero kuti kupasuka kumayambitsidwa ndi kulekerera kwa makulidwe a zigawozo.

3. Buckling kupsyinjika kwa PCB, makamaka pambuyo kuwotcherera, akhoza kuyambitsa akulimbana zigawo zikuluzikulu.

4. Zigawo zina za PCB zitha kuwonongeka zikagawidwa.

Njira zopewera:

Mosamala kusintha kuwotcherera ndondomeko pamapindikira, makamaka preheating zone kutentha sayenera kukhala otsika kwambiri;

Kutalika kwa z-axis kuyenera kusinthidwa mosamala mu makina a SMT;

Mawonekedwe ocheka a jigsaw;

The kupindika kwa PCB, makamaka pambuyo kuwotcherera, kuyenera kukonzedwa molingana.Ngati khalidwe la PCB ndi vuto, liyenera kuganiziridwa.
