[Suggestions]Create oblong pad and oblong hole with any dimension

Gabriel Gabriel wrote:

Hello,

 

I have a suggestion for you. You should have a function that allows

users can create oblong pad and oblong hole with any dimension like

Orcad and Altium, for through-hole components. There are many components

need oblong pad and oblong holes nowadays. For examples, this component

need oblong pad and oblong hole.

With Orcad, users can adjust pad with and pad height of oblong pad.

Sometimes, users only need oblong pad long and narrow, not too big like

EALGE does.

With Altium, users can create hole, pad with any shape.

 

Support for Rectangular Pad Holes | Online Documentation for Altium

Products

I think you really must have this function in new version if you don't

want users use Altium replace EAGLE because you only don't have this

function. Don't tell that the boardhouse can not create oblong hole to

the users! They can!

 

A topic was created on Mar 10th, 2015, but there is no one reply that

topic.

 

Waiting for your respond!

 

Thank you for reading!

 

Best regards!

In the past, oblong holes basically meant the holes had to be milled out

(obviously one cannot drill oblong holes except by accident) at a usually

significant extra cost. Where are you folks that are using oblong holes

getting your boards made, and how much of a premium do you have to pay for

using oblong holes? Are they primarily used by hobbyists doing their own

milling, or by the military/industrial folks with unlimited budgets? Or is

the increasing use of laser cutting making oblong holes an affordable option

these days? I'd love to know. Thanks.

Hi Bob,

Oblong plated holes still have extra cost, because the milling need to be done before plating, so it can not be done while milling the outline of the board.

If not plated, the oblong hole can be done during the milling the outline of the board, and there is no extra cost (if it can be done with same tool (same diameter)).

I don't know about the laser cutting, but I think that don't solve the problem of doing it before the plating process. And I don't know if a laser cut is better than a milled one, because I know that one of the main problem with plating it to have  a very clean cut... if some one know ... it can tell us (I'm curious...)

Anyway, I avoid plated oblong for that extra cost, but a couple of time I had to use them, since some connector need oblong, and I didn't had choice of the connector....

The price of that extra cost depend on the house board, on how many board you buy etc....

Thanks for the reply. Most oblong holes I've encountered on connectors are

primarily an artifact of the manufacturing process of the connector; namely,

the manufacturer uses a punched-out and bent piece of the sheet-metal shell

as a leg. In most cases these are primarily shell ground connections and/or

mounting tabs, and simply using the nearest round drill diameter that will

fit the tab does the intended job. However, as these connectors get smaller

and smaller, that extra radius can start blocking routing channels out of

the connector pins, so I'm always interested in hearing from folks who may

have found ways to manufacture non-round 'drills' at less cost than milling.

Once that process is available, I'll be right there with you pushing Cadsoft

to give us that oblong functionality.

Hi,

I don't expect a oblong hole functionality since in my several years experience I only used oblong holes twice !

And it was small connector (a USB connector) )with a shell-leg, too near other pads, so a bigger round hole was impossible.

I have the feeling that, connector manufacturers become aware that and now try to avoid  the need of oblong holes. It's just an feeling, I may be wrong...

Any way, I'm aware of that, and I take in to account this kind of details in my designs when I choose connector (or other part).

So I think it would certainly be easier to have a Oblong hole functionality, but I think it really not a priority, other improvements such as separate diameter for top/bottom, separate Mask option for top/bottom.... are more interesting....
