Ways To Achieve Consistency Flashcards
What are depth stops?
Long rods that are clamped close to the drill bit of some drills.
They allow you to drill a hole to an exact depth in whatever material you’re drilling.
How do depth stops allow the manufacturer to only drill to a specific length?
Once the depth has been reached, the depth stop will come into contact with the material and will prevent you from drilling any deeper.
How can depth stops be adjusted?
The depth stop can be clamped in a different place, allowing you to carefully control the dimensions of the hole.
Why do laser cutters need to be programmed correctly?
To cut the material accurately.
What on a laser cutters needs to be programmed correctly?
The dimensions of the component (so it knows exactly where to cut).
The correct power settings and feed rate (the speed at which the laser moves and cuts the material).
Why does a sample need to be checked when laser cutting?
To make sure the machine hasn’t malfunctioned properly been incorrectly programmed.
What do PCBs stand for?
Printed circuit boards
How are PCBs manufactured?
Through photo-etching - the PCB is exposed to UV light, a developer solution and an etching solution.
Why do exposures times need to be carefully selected when manufacturing PCBs?
Exposing for too long causes the copper tracks to be removed.
Exposing for too little causes unwanted copper to remain on the board.
Why should the exposure time remain the same for every PCB that’s produced?
To make sure that the PCBs are of a consistent quality when output.
