💡 Hint

Common Mistakes

Using 'manual' instead of 'interactive' which is the correct mode name.

Choosing 'auto' which is for automatic routing.

The interactive mode enables manual routing with real-time feedback.

💡 Hint

Common Mistakes

Selecting 'bottom_copper' which is the opposite side.

Choosing 'silkscreen' which is for markings, not routing.

The top_copper layer is used for routing on the top side of the PCB.

Fix the error in the code to correctly start the interactive router with grid snapping enabled.

PCB Design

router.start({ [1]: true });

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'snapGrid' which is incorrect property name.

Using 'enableGrid' which is not recognized.

The correct property to enable grid snapping is snapToGrid.

Fill both blanks to configure the interactive router to use the differential pair mode and set the clearance to 0.2mm.

PCB Design

router.configure({ mode: '[1]', clearance: [2] });

Drag options to blanks, or click blank then click option'

C0.5

Dsingle_trace

💡 Hint

Common Mistakes

Using 'single_trace' mode instead of 'differential_pair'.

Setting clearance to '0.5' which is larger than required.

The mode differential_pair is for routing pairs of traces, and clearance 0.2 mm sets the spacing.

5fill in blank

Fill all three blanks to start the interactive router with the following settings: mode as 'auto_route', enable via stitching, and set the trace width to 0.3mm.

PCB Design

router.start({ mode: '[1]', viaStitching: [2], traceWidth: [3] });

Drag options to blanks, or click blank then click option'

Dauto_route

💡 Hint

Common Mistakes

Using 'interactive' mode instead of 'auto_route'.

Setting via stitching to 'false' or '0'.

Using trace width other than '0.3'.

The mode auto_route automates routing, true enables via stitching, and 0.3 mm sets the trace width.
