প্রশ্নোত্তর:
What is the difference between SMT and PTH assembly?
SMT assembly mounts components directly on the PCB surface, while PTH assembly involves inserting component pins into holes and soldering them.
Why is solder paste stored in a refrigerator?
Solder paste is stored at 0-10°C to maintain its quality and prevent degradation before use in the SMT assembly process.
How does AOI inspection improve the SMT assembly process?
AOI inspection uses cameras to compare assembled PCBs with reference images, identifying defects like bad solder joints or misplaced components to ensure high-quality production.
