Dumping Data from a UF 3000 Binary Map File

The wmapconverteng.exe engine can be used to make a complete "dump" of the UF 3000 Binary map file format. This ASCII output can be useful for examining the contents of the binary file.

Syntax

wmapconverteng.exe  input_file_name  output_file_name   -dir:directory -inputformat:UF3000 -uf3000_info

where:

wmapconverteng.exe      wafer map convert engine exectuable
input_file_name         name of the Binary UF 3000 file to process
output_file_name        base name for output text file
-dir:directory          directory where the output file should go
-inputformat:UF3000     identifies the file as a UF3000 binary file
-uf3000_info            directive to produce an ascii data dump

Sample ASCII

I've obfuscated some of the proprietary data in this file

P46X71-21B7

This is a 164KB UF 3000 binary file as our input. It produces a 13.3 MByte ASCII file.

Index File

An index file (.idx) of map data is not used or considered. We are only working directly with the MAP file itself. The documentation indicates that map file names take the form: MAP_NNNN.DAT but we have not found this to be the case when clients send us map files.


Reference Device

Probers must identify and use a known reference device in order to test a wafer. The UF3000 MAP file appears to allow a number of different ways to define a reference device.

Let's examine these options and look at data we've received from sample files.
