How do you draw pin grid array in cadsoft Eagle PCB?

I'd like to use a processor that uses a pin grid array. Basically, I'd like to make the prototyping PCB board for it. I'm new to eagle. How can I connect the inner PGA pins to the header pins on the edge (without shorting the lines)?

Try not to make so long because your outer pinout is sensible. you should be able to do most of this on one layer. With a standard 5 mil trace/space process, you should have no problem fitting a trace between two pads. It should be possible to route that whole thing on one layer.

What Others Are Asking

What is the proper zero orientation for a SMT LED?

According to IPC-7351, the cathode should be on the left for a molded diode. However, when I use component wizard of my suppliers to create a diode, it places the cathode (K) on the right. Does it depend on the manufacturer? How does the assembly house know which way is correct?

Is double-sided mounting still possible with the latest packages?

When I think of packages like some DFN or 0201 resistors I wonder where they would place glue dots. My UDFN is 1.2mm x 1mm. And glue dots on 0.5mm pitch WLP seem completely out. Is it still possible to fix parts at the bottom of a PCB for soldering?

What is an average CPH speed for hand SMD assembly?

What would be the average speed of assembling surface mount components on to a PCB for an experienced person? Assuming they have desk that is correctly set up (pick and place station) and the PCB has solder paste already applied.
