Incorrect chip insertion to ZIF-panel of programming tool

[AlexGG]

Hello.


Does anybody knows how to do checking of incorrect device insertion in programming tool.

In description of tool is written:
"Check for incorrect device insertion, backward, incorrect position, and poor pin contact. "

How to do this?

Re: Incorrect chip insertion to ZIF-panel of programming too

Universal programming tools cater to a large variety of chips so a large, wide slot ZIF socket would be provided which can accept all the chips to be programmed.

This would be number of pins from eight to sixtyfour, width .3in or .6in, and so on.

Some work together with a PC and in this case it is customary to show on screen a picture of the chip as it should be seated in its socket.

A stand alone tool will come with a handbook detailing how the chips should be inserted.

Correct insertion - might I say RTFM?

Correct polarity - Look at the position of the notch, every time!

Contact on all pins - You have to check that all pins are straight before inserting into the ZIF socket. A new component should have straight leads, but a component being reprogrammed might have had its pins bent out of shape while it was extracted from its previous socket. It pays to use a proper ic extraction tool, obviously.

Its all common sense, really. Good Luck.
