Basic Stamp Removal

Stampers,
I have several BOEs and five different Stamps and have had the need to remove and replace Stamps on the BOEs. I use a small screw driver with a 90 degree bend on the end to gently pri the Stamp out of the socket. This has worked well with the Stamp (and other socketed ICs) and I have never bent a pin or damaged a chip. However the last time I removed a Stamp·I noticed there are some traces on the bottom of the Stamp board. I got to thinking that there might be·the possibility of damaging or scratching these traces with the screwdriver.·To prevent scratching the traces I placed a small piece of shrink tube on the end of the·screw driver·to prevent damage to the bottom of the board.
I have two projects that have ZIF sockets in them but don't have any of my BOEs (ones I had did not seem to fit very well).
Anyone else use a different method of Stamp removal?

Mike S.

    I have a ZIF socket on the NX-1000 board and it works fine. Don't see why it wouldn't work on a BOE.

    Do you have a Stamp Tester?

    I read the "bent screwdriver" technique in a blurb in a recent Nuts&Volts magazine.· How totally STUPID!· Prying the IC one end at a time can put a lot of stress on the legs and even bend or break them.· You should pull the IC out straight.· Dad allways taught me to use·the right tool for the right job.· An IC DIP Extractor is what you want.· It looks like a pair of tweezers that are bent at the ends.· Your talkin' maybe $5 or $6·at Radio Shack, Digikey, etc.··

    These work just fine on smaller DIPs, say under 14 and under pin count. But I've bent more pins using the cheapy tweezer style extractors than I have with any other technique. Maybe it's just me and others have better luck with them.

    I'm with you, Jim.· Takes a mighty pull to get a Stamp out of its socket, and chances are when it does come out it will go flying.· For years I have used a small screwdriver to carefully pry the Stamp out of its socket.· I k\let the blade of the screwdriver rest on the Stamp socket and push the Stamp up with the screwdriver's round shaft.· Never lost a Stamp [noparse]:)[/noparse])

    As I said before, I've never bent or broken a pin with the bent screwdriver. I too have·used DIP IC extractors over the years and find them awkward on tightly seated chips. I have even used the fancy ones that have a scissor action for a mechanical advantage. Now that I have the tip coated with shrink tube to prevent scratching the underside of the BS2 I'll continue to use the STUPID bent screwdriver.

    I just stack a couple of sockets. not good for steamlined applications though.

    Huh?

    Do you mean that you put the stamp, or whatever chip, in a socket and then plug it into the socket on the PCB? I never thought about that, but it seems like it ought to work pretty nicely.

    Thats exactly what I meant, it saves your stamp pins from getting bent and extra DIP are cheap, plus they seem to come apart a bit easier.

    Cool idea. Thanks for posting it.

    You should learn one new thing each day. That's my thing for today. Now I can go back to bed.

    Johnny,

    Thanks for the post. I'll give it a try.

    O.K.... so maybe I was a bit hasty about it being "stupid"... since I am such a neophite, I concede to your collective experience and wisdom. I will go to the Dollar Store tomorrow and buy a screwdriver (for $1), bend the tip, cover with shrink tube and give it a try. BTW, I like the "socket" idea... once I give the "screwdrive" method a try, I think I will incorporate the 'socket" idea on all future work!

    Thanks!

    Steve,

    The important part about the screwdriver is to gentle pry each side a little at a time, working the chip up and out. I'm sure I'm stating the obvious, but, prying one side completely out, then the other, will result in bent and broken pins.
