Low plating index

Former Member

Ok so I just got a issue back from my board house, I combined 5 pcbs in one panel.

 

You can see the info in the uploaded picture. The plating index is low and it need to bost it up. I understand I need to make the copper distribtion move even (even though im not sure what 'even is') Am I right in saying one way is to add copper traces which dont do anything where I can on the board? Or I read somewhere that you can fill another layer with copper or something like that. Only thing is im working with eagle light so I only have two traces which Ive used both as much as each other on all the boards.

 

 

Also where it says it may get brunted for instance where the redish color is on that 10 pin header. That is because I had to ground 4 of the pins, I dont think there is anyway round this as I need to keep it like that. I also attached a zoomed in pic.

 

 

Could anyone take a look and tell me what is acctually bad and what needs to be changed. And how I need to go about doing that on eagle.

 

Thanks!

    I dunno what this "plating index" stuff is.  You can always ask -- your

    PCB vendor probably already knows you're a newbie, so asking naive but

    intelligent questions will only raise their impression of you.

     

    At a guess if you fill the areas between boards with a grid of traces

    then your copper would be more even.  That may make them happy.

    Why am I not happy that they have found common ground?

    Yeah, im just waiting for a reply back from them!

     

    I think its pretty much about a even copper distrubtion. They said they will fill the areas between boards to even it out. But could you shed some light about how you would go about getting a even copper on a single pcb after the traces have been put down image

    The PCB house I use told me that they need a "similar" proportion of

    copper vs. gap on all layers, but they were OK with a corner of the

    board being very sparse on all layers when the rest of the board is

    extensively flood-filled. It sounds like YMMV, though.
