Subject: [DC] Tips wanted for my first multilayer board?


>Hello everyone,
> At last, my employer has decided that on my next board I can go past the
>normal 2 layer restriction that
>I normally have. (I've been waiting for this for years!)
>The board will have amongst its components a MQFP208, and be a very tight
>fit given the number of components
>on it and where it is to fit (but then theyre all like that ar'nt they!).
>
>Anyhow, the boss is letting me have... wait for it... 4 layers to use.
>Now this may not be in the same league as all you guys doing 12-16 layers
>etc, but I gotta start somewhere.
>
>Where do I start?
>
>Ok say I got the SMT components all placed on one side, are there any
>suggestions or tips that you multilayer experts
>can give me for designing with 4 layers?
>I've got  funny feeling that I cannot get a power/groundplane on the
inside.
>I've been advised to steer clear of blind via's and have them all the way
>through.

>Are there any websites with multi layer info on?
>Cheers - Matthew Lamkin.
