40 pin sockets

Started by jrem123 February 14, 2004
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,
like 5-56 or WD40, the socket will let go of the chip much easier...
especially if it is oiled before the chip is inserted.

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,
no need for screwdriver either as the chip is easily lifted out between thumb and index finger.
A dual wipe socket might well have killed the chip the very first time.

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.

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.
