Where does the resistor terminals have to be soldered in PCB
On Via
On Pad
Tracks
On any component.
The line in between two pads is called
Jumpers wire
Tracks
Pad

What does engraving process do to PCB?
Isolates all tracks and pads from entire metal layer.
Chemically remove unwanted metal from PCB.
Only make holes to the PCB
Just to draw names and silk resist of the circuit.
Which of the following is equivalent to wire for conducting signals?
Tracks
PCB
Via
Pad
PCB method which allows the components to be simply set on a board not requiring that leads pass through holes in the board is called
Plated through
Solder mount
Surface mount
Solder mask
Where can surface-mount components be normally mounted on single layer PCB?
Not allowed in single layer.
On both layers.
Only on fiber layer.
Only on copper layer.
When using a single layer PCB and it is impossible to connect complete a track connection it. What will you do?
Leave the circuit as it is.
Try to find another design.
Make a crossover track.
Complete the track by a jumper wire.
In the process of the following connections between layers
