I am using Lassen iQ with PIC to display lat/long on LCD.When i use the module on Eval Board it quickly get Fix but when I use it on my own PCB it does not track more than 3 satellites and hence no Fix.Is there some kind of noise problem due toPCB design ?

It sounds like there maybe a problem with your PCB design. Where are you placing your GPS antenna? Could you take a picture of your PCB and post it on here? Maybe some of us could check it out and give you some feedback. I had a lot of trouble getting a fix with my EM406 module with a patch antenna. I had to make it wasn't near any other electronics or at least above them.

I'm no expert at PCB design but im sure others on here are. :)

Later,
