hi! can anybody tell me, where i can define in protel99se, that the autorouter places no vias at pads? i=B4d like to design a 2-layer layout to solder by hand. so there must not be vias directly at pads of components. because i can=B4t solder them on the toplayer...=20
many thanks in advance!!
In my experience, Protel does not place vias in pads - any CAD system that did would be seriously flawed.
You can create your own component footprints that have pads only on the bottom layer - then the autorouter will be forced to connect to them on the bottom layer.
(By the way - you can route your board manually if you wish - then you have full control of how you connect to component pads, and where vias are placed.)
This isn't true. There are plenty of PCB manufacturers and board builders out there who are perfectly capable of dealing with "via in pad" designs; being able to utilize such a feature can produce noticeable improvements in signal integirty as well as board density.
That being said, I've never seen a PCB system that couldn't be set to keep vias out of pads, since it is the more traditional/lower tech way of doing things.
You mean you don't want a PTH don't you ?

thanks, for your answers...!
okay - to create footprints without "toplayer-pads" - that would be an idea!
@graham: no, i=B4d like to create a PTH
