What do you guys use to remvove a 40pin chip like the 16F877A from a dual wipe socket? I've been looking around Mouser for something to no avail . . . Regards, John. |

Those dual wipe sockets really aren't meant for chip removal (I think).
I've torn a lot of pins of chips because of these sockets. I NEVER use them anymore...the turned type is much better(best). However if you already got it stuck in a dual wipe you may find it useful
to apply some oil,

When all you have is a screwdriver the PIC will get screwed. After a few removals a pin will break, but I use ICSP so the number of removals is small.

Well...
I have now had my PIC18 DIL40 in/out of the socket at least 500 times.... same chip..same socket. nedless to say the socket have been oiled once or twice , and it is
a turned type,

I use a small, thin, wide screwdriver which was heated, then bent to not quite a right angle (bend the wide, flat side). The bent lip is between 1/8" and 3/16". Use it to gently lever the chip out, alternating ends frequently. Normally takes a few seconds to do it properly but neither the socket or chip gets damaged. Dual wipe sockets are great - much of my stuff is mounted in high vibration environments and they hold better than anything else I've tried. I solder in what I can but some stuff does need to be in sockets. dwayne -- Dwayne Reid <> Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax Celebrating 20 years of Engineering Innovation (1984 - 2004) .-. .-. .-. .-. .-. .-. .-. .-. .-. .- `-' `-' `-' `-' `-' `-' `-' `-' `-' Do NOT send unsolicited commercial email to this email address.

I put my chips in machined sockets and then insert them into the base socket (yes, 2 sockets and the PIC). That way, if I break a pin on the socket, I can always pull the PIC and use it directly in an "emergency". Also, the machined pins are much easier on the base socket. But as Wouter was saying, with ICSP, you almost never have to pull a chip.
