Low plating index

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

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.
