1. What is the main purpose of a Gerber file in the electronics industry?
To simulate power flow through circuits To communicate design information to manufacturers To store component datasheets To control soldering temperature profiles
2. Which Gerber file format is the most commonly used today?
RS-274D DXF RS-274X ODB++
3. What distinguishes RS-274X from RS-274D?
RS-274X uses fewer file extensions RS-274X embeds the aperture list in the file RS-274D includes a 3D rendering RS-274D requires fewer files per layer
4. Which of the following programs is used at MCL to view Gerber files?
EagleCAD View Mate Altium Designer SolidWorks
5. What type of information is included in a fabrication file or specs?
Only copper layers Only silkscreen information Drill maps, stack-ups, and file references Component placement diagrams
6. What is a key difference between an NC drill file and a drill map?
Drill maps show 3D holes NC drill files are only visual representations Drill maps are used only during testing NC drill files include measurable coordinates, drill maps use symbols
7. What file extension might indicate a top copper layer?
.l2 .bl .top .silk
8. What is typically shown in silkscreen files?
Copper trace routes Component location text and markings Heat dissipation paths V-score cuts
9. What does the black area in a solder mask Gerber file represent?
Exposed copper Drilled holes Areas where solder mask will be placed Component outlines
10. How can you differentiate one Gerber layer from another?
Drill hole size Board shape File extension and stack-up information Silkscreen font
