What Color Are Your Blue Wires?
April 27, 2011
You design a circuit board and of course you will most likely have to blue wire (rework ) it. I call them “Blue Wires” because at my first job we used blue wire. “DeadBugs” were extra chips that were glued upside down on the circuit board for rework. DeadBug, like Blue Wire, became a verb as in “Just deadbug a dual op amp on the board and get that board into test. Yesterday I was giving a seminar up in Vancouver and I asked that question. I found everybody used blue wires, but some had white blue wires, others used gray blue wires. One guy said they used whatever color that was laying around blue wires. Well PSoC uses blue wires but no one know what color they are because they are all on the inside. It also takes a lot less time to rework your PSoC than to rework your board. So when you have work three weeks without a weekend and you go to show the CEO your board, there will be no obvious markers of last minute fixes.
