ic socket for 44 pin smd

[--BawA--]

i am using a dspic33 series ic , which is of 44 pin count , this ic comes in package like TQFP-44 , QFN. i want to use socket in my pcb board ,so that i can easily replace the ic , so is there any socket present for these packages?

Yes but can you afford it?

$55 **broken link removed**

I thought these were EOL/obsolete and MOUSER has no stock

This is china-made, cheap but useful, less than 1usd

The socket shown in post #3 is a PLCC type, no suited for TQFP package. PLCC sockets, both through-plated and SMD, have been often used for EPROMS and are of course still available.

For TQFP, QFN and similar packages, only relative expensive test and programming sockets (see post #2) are available. The most problematic point in my view is their huge size which requires to design a PCB specifically for test socket usage. A possible option to change ICs quickly would be a header board, e.g. a Microchip PIM module from the shelf.

thanx to all. i got the idea.
