Combination of Test and ISP
When programming flash at ICT the
programmable devices are tested as well as programmed, and in most cases the failures are
diagnosed down to the pin level. An off-line station only produces a go-no-go message.
With pre-programmed parts there is no guarantee that the device was correctly installed.
Speed
In many cases programming at ICT is
actually faster because the parts are programmed directly. You are never at the mercy of
an inefficient download utility. Multiple like-kind devices can be programmed
concurrently.
It Simplifies Your Inventory
If you have many different programs for a
single raw part, and you have your devices pre-programmed, you have to stock a different
device type for each program. If you program at ICT, you simply stock the one raw part.
Quality
ICT programs your part and verifies it. If
you pre-program your parts there is not much to assure that the correct program was
installed on the correct board.

much money will be saved when you totally eliminate one station in your test process.
