If you ever wanted work with SMD components in PLCC44, 52, 68, 84 and 100 and found it very difficult to connect the IC (s) to other parts of your board, then you find this board extremely usefull.
On the front, this board allow you to connect any PLCC IC and have easy access to all the pins, and on the back, you can connect components in 0.65mm PQFP and TQFP in 100 and 144 (normally sold for $50-$60) pin package.
I have received a new batch of these boards and you can purchase them from me at the unit price of $15 (free shipping worldwide)
