When the board is taken out of the developer it must be washed in clean water before transferring to the etching tank.
True
False
Why should you not leave a PCB in the etchant tank for too long?
It will start to dissolve the PCB
The copper tracks will be removed or damaged
It will start to give off harmful fumes
It will damage the quality of the etchant solution
What is the next stage after you remove the PCB from the etchant tank?
It is washed
The component holes are drilled
You solder the components to the board
You repair any broken tracks
What is the name of this piece of equipment?
Mini pillar drill
PCB drill
Circuit drill
Board drill
How are PCBs manufactured in industry?
Individually populated by highly skilled workers
A production line populates the components but someone solders them to the PCB
Designed on a computer and then manufactured on an production line controlled by computers.
