I'm having a trouble by doing a real project with digital system design. Basically I ordered the Cyclone II TQFP 144 pin, but then it says "BAKE" the chip. The moisture sensitivity strip became pink from blue when the seal is opened. So I guess I have to bake the chip before soldering.... but what does it mean by "BAKE" the chip? How can we BAKE the chip? I'm pretty sure we don't cook these. Also, why do we need a socket for TQFP or any other FPGAs? What are the "burn-in socket" and "test socket"? What are the advantages of using the sockets? Will the FPGA be damaged if I just solder them on a PCB? and the sockets seem to be very expensive.. anyone know a good cheap socket? It's my first time buying FPGA and putting it into a digital system. Please help me! Thanks!
