plated hole and non plated hole question

masamasa

hello

  

i received a design file from our customer.

  

i ran the db doctor and it gave me the following warning.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

WARNING(SPMHA1-97): Illegal drill plating.
Non-Plated hole has connected objects, consider changing to PLATED.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  

the padstack is defined as an smd pin used on inner layers and no drill hole defined as shown below.

  

how do you define a plated hole and a non-plated hole on the padstack?

  

can an smd pin be defined only on the outer surface layer?

  

if so, how can i define a pad with no hole used on the inner layers on the padstack?

  

regards

masa

    Hi masa,

    It's odd that you have an SMD pad but at the same time you're getting a warning that suggests a NPTH hole modification. 

    However, regarding your queries:

    1- The plated/non-plated hole setting is in the seccond tab of the padstack editor: 

    2 - Yes, an SMD pin can only be defined as an outer-layer pad. Simply choose BEGIN LAYER in the Layer Name column: 

    3- The only way I think you can have an SMD pad in an internal layer would be to create a regular SMD pad and then create a symbol, add the padstack to the required layer? Not really sure if that would be the best approach.

    thank u for ur reply. i have tried #1 above but it still gives me the same warning.  unfortunately i can not try #3 above to create a symbol as this is our customer's design. most likely as u mentioned on #2 aove, the problem could be the padstack assigned as an smd pin and placed in the inner layer.
