This is to hold the QFN in a stationary position while we engrave the necessary numbering for our chips.
The + indicated the 0,0 position of the laser engravers of the choice.
The o indicated the position of the first pin of the package must face.
Included will be svg file which was used to generate the pdf necessary to use this bracket.
there is a tolarence of 1 mm, which is terrible but it worked for the application in our interested.
The laser engravors that we used were Rayjet 50.
Potentially improvement is to make the grooves smaller to make a better fit.
