Re: curious about electronics manufacturing process

Let's say, for example, that I'd like to design a wireless karaoke
device. (Just for the sake of example. A Google search results in
quite a few of these things.)

What would the process be like, from concept to finished product?
(Where would I start, who would I hire as contractors, etc.?)

Here's what I've got so far:

Concept

Where did the concept come from ? Market research ? Blue sky thinking ? A useful
outline spec is needed.


Attorney (patents, etc.)

Few things are patentable. Forget the useless overhead cost jerks OK ?


Electrical engineers + programmers

Their first job is to look at the concept and see it it'll work. If it doesn't
they may come up with a solution that does the same.

A couple of prototype iterations are normal btw. Who does the pcb layout in your
scheme of things btw. You'll need a draughtsman or two.

Don't forget protoype evaluation ideally with existing customers to iron out any
unforseen bugs.


I'm drawing a blank right around here:

Product molding and packaging (what is the trade name for these guys?)

Mechanical design. Don't forget the 'pretty' factor. Graphic designers etc.

Even the 'carboard box' has to be designed ( hopefully to actually provide some
useful level of protection to the product - to be checked by drop testing ).


Mass production (probably offshore) : how does one establish contact
with such folks? How would one know whether they are trustworthy, etc?

Contacts, luck, experience.

The sub-contractor will need info to test your product. Ideally complete test
jigs and test prodedures should be supplied.

Who's going to write the user manual btw ?


I'm sure lots of you guys have designed and built finished products;
just curious how the full route goes.

Don't forget standards compliance ( safety and EMC ).
