Section 7 Making Principles Flashcards
benefits of using STANDARD components when manufacturing products
Use of similar components across a range of products meaning lots of identical components can be bought in bulk resulting in economies of scale.
• No need to design and manufacture own components as standard components can be bought in.
• Standard components are mass produced so they are low cost to the manufacturer.
• Speeds up the manufacture of products.
• Components are quality assured before they arrive at the
manufacturer for them to use.
• Defective standard components can be easily replaced as part of
a manufacturer guarantee if needed.
• Save on assembly time as this can be left for the customer (KD
flat pack assembly). No need to use factory space for assembly.
What is Dimensional accuracy
Important to ensure products are manufactured within tolerance, eg length, width, thickness, diameter, resistor tolerance.
• Use of jigs, templates and stencils to ensure consistent sizing is used.
• Adoption of CAD and CAM to work to a very fine tolerance better than a human.
• Promote precision, reduce product/component defects.
What is Process time
Developing times in PCB manufacture. Avoid over exposure of a PCB board to UV light.
• PCB etching limit time in a PCB etch tank to ensure copper tacks are not removed/become porous.
• Correct drying and curing times adhered to before loading/product use.
What is Registration accuracy
Check the quality of printing in an image.
• A circle with a cross through it is used to check
if all inks printed are correctly aligned.
• Make sure image is not blurred – circle and
cross lines will appear blurred.
