medium📝 Formula Result Q4 of 15
Step-by-Step Solution
Solution:
Step 1: Understand the function of solder mask files
Solder mask files define areas to be covered with protective coating to prevent solder bridges.Step 2: Analyze the effect of a blank solder mask file
A blank file means no areas are masked, so copper is fully exposed, risking shorts and corrosion.Final Answer:
The entire PCB surface will be exposed copper without solder mask protection -> Option BQuick Check:
Solder mask blank = no protection [OK]
Quick Trick: Blank solder mask = exposed copper [OK]
Common Mistakes:
MISTAKES- Assuming blank means full coverage
- Confusing solder mask with silkscreen
- Thinking blank solder mask adds extra layers
