Name Selection in Column -

Jackie_ — Fri, 09 Jun 2023 16:08:32 GMT

Hello JMP Community,

A bit challenging problem - I am trying to select Name Selection in Column

matrix [X,Y] of 26 x 29 points.

Create a Column in the data table and highlight them as below

Is there a way to Name all the with jsl instead of manually selecting and naming them?

I have attached the XY table

Any suggestions would be much appreciated :)

Thanks a lot,

The best community

Hi Jackie,

It is much more work to do this numbering reticles 1, 2, 3, ..., but it is easy if the reticles are labeled with an X_Y, where all reticles in the same column will have the same X, and all reticles in the same row will have the same Y. In this way, the X_Y label for the reticle contains meaningful location information, just as the actual X Coord and Y Coord contain meaningful location information.

In this case you can use a formula:

Char( 
	Ceiling( (((:X coord + 26) - 23) + 1) / 26 ) 
)
 || "_" || 
 Char(
	Ceiling( (((:Y coord + 29) - 31) + 1) / 29 )
)

Let's explain:

In the first part, we use 26 in two places because 26 is the width of a reticle. In the second part of the formula, we use 29 in two spots because 29 is the height of a reticle.

We use the values "1" to adjust after subtraction.

Now the offsets: In the first part, we use 23, because this is the lower x boundary of those reticles lying furthest to the left, that have at least SOME of their left edge on the wafer.

Likewise, we use 31 in the second part, because this is the upper y boundary (since we are using reversed y-axis convention) of those reticles lying furthest to the top, that have at least SOME of their top edge on the wafer.

Using this formula, and a global (not local) data filter on the table, along with your graph, we see that the naming convention allows you to select individual reticles as needed.

I have attached your table with the formula column and data filter script included so you can try this out. Hopefully this works well for you. If you still need to number the reticles 1, 2, 3, you can do this afterward by sorting the table, summarizing it, and numbering consecutively, ignoring reticles with no dice on the wafer. Hopefully you will not even have to do this, and the naming convention will be OK for you.

Cheers,

Brady

Hi @brady_brady ,

Hope you are doing well!

I have a quick question regarding the offset part - Is there a way to find the offset value for the lower x/y boundary of those reticles lying furthest to the left/top by calculation/automatically instead of finding it manually?

I would really appreciate your response.

Thanks.

Jackie
