Protel99SE - no vias at pads

Feb 07, 2006 7 Replies

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!!



Sorry, don't know Protel, but as a general rule: vias should never be on pads, they suck away the solder. I know, I've tried it :o(

Another rule: don't use the autorouter.

You shouldn't _have_ to solder at the top layer, if they're actually plated-through holes. It's all one conductor, you see. There is absolutely nothing wrong with using leads as vias - if you've got plated-thru holes, do you solder ordinary components that have a trace on the component side? It's the same thing.

Good Luck! Rich

Which is why it is so obvious that he was talking about boards without plated holes.

I agree with Deefoo: avoid the auto-router as much as possible.

However, try with this learning guide

formatting link
ssentials.pdf. It's about DXP version and it can differ from 99SE but maybe could help you to find a solution to your problem: for example, as it says on page

5, try to put Via Control (if you have it on 99SE) to minimum (slowest auto-routing).

Regards and good luck,

Quitus.

thank you...!

and what about non-plated-through holes? when the pcb is not been manufactured? how should the "top-pad" been connected to the lead without soldering?

@Quitus: thank you - with the via control setting to minimum i have less vias - this i also don=B4t want to...
