What I have tried:

static Dictionary<string, Tags> m_showChipList = new Dictionary<string, Tags>();

epc = 1234555622344;
tid = 2223444222134;
pathpcbit = @".\Resources\cross.png";

m_showChipList.Add(writeResult.Tag.Tid.ToString(),
                                      new Tags
                                      {
                                          PCBit = pathpcbit
                                      });

public class Tags {
     public int NUM { get; set; }
     public string TID { get; set; }
     public string EPC { get; set; }
     public string PCBit { get; set; }
     public string WEPC { get; set; }
     public string UACCESS { get; set; }
     public string UKILL { get; set; }
     public string WACCESS { get; set; }
     public string WKILL { get; set; }
     public string LACCESS { get; set; }
     public string LKILL { get; set; }
     public string CEPC { get; set; }
     public string CACCESS { get; set; }
     public string CKILL { get; set; }
     public string CLACCESS { get; set; }
     public string CLKILL { get; set; }
 }

PCB.Add(new Tags()
                        {
                            NUM = i,
                            TID = tag.Tid.ToString(),
                            EPC = tag.Epc.ToString(),
                            PCBit = m_showChipList[tag.Tid.ToString()].PCBit,
                            WEPC = m_showChipList[tag.Tid.ToString()].WEPC,
                            UACCESS = m_showChipList[tag.Tid.ToString()].UACCESS,
                            UKILL = m_showChipList[tag.Tid.ToString()].UKILL,
                            WACCESS = m_showChipList[tag.Tid.ToString()].WACCESS,
                            WKILL = m_showChipList[tag.Tid.ToString()].WKILL,
                            LACCESS = m_showChipList[tag.Tid.ToString()].LACCESS,
                            LKILL = m_showChipList[tag.Tid.ToString()].LKILL,
                            CEPC = m_showChipList[tag.Tid.ToString()].CEPC,
                            CACCESS = m_showChipList[tag.Tid.ToString()].CACCESS,
                            CKILL = m_showChipList[tag.Tid.ToString()].CKILL,
                            CLACCESS = m_showChipList[tag.Tid.ToString()].CLACCESS,
                            CLKILL = m_showChipList[tag.Tid.ToString()].CLKILL

                        }); PCBProgrammer.Items.Add(PCB);

I would suggest you to start by reading about MVVM:
Model-View-ViewModel (MVVM) Explained[^]
MVVM for Beginners[^]

You would setup a model that is a collection for your grid as source. Columns in it mapped to fields in the object type you made collection of.

Now, in your case above, if you want to do it using a dictionary, it would be something like:

HTML

<Window x:Class="DictionaryDataGridDemo.SingleDictView"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:DictionaryDataGridDemo" 
    Title="test"
    Width="500"
    Height="300">
    <Window.DataContext>
        <local:MyViewModel />
    </Window.DataContext>
    <Grid>
        <DataGrid AutoGenerateColumns="True" ItemsSource="{Binding MyDictionary}">
        </DataGrid>
    </Grid>
</Window>

ViewModel

C#

public class MyViewModel
{
    public Dictionary<double, string> MyDictionary { get; set; }

    public MyViewModel()
    {
        MyDictionary = new Dictionary<double, string>();
        MyDictionary.Add(100, "AAA100");
        MyDictionary.Add(200, "BBB200");
        MyDictionary.Add(300, "CCC300");
    }
}
