Any tips for 4-layer boards?

Wow, I didn't know you could make it without a stencil. But you are right, for a prototype why spending more money. I might try it in the future.

I have soldered 44-lead TQFP pics like the one you have in your pictures and I usually get my plastic stencils from www.ohararp.com. They are inexpensive and do the job. I have also tried pololu.com that was mentioned by dhouston. But for a bigger production I would recomend you panelizing your boards and using www.stencilsunlimited.com.

Thanks Dave and Robert for the links!

I've bought from stencilsunlimited before.. that's where I got my solder paste and flux.

I took a quick look at the ohararp, pololo, and quickstencil sites and they got bookmarked for future reference. Sooner or later stencils will become a necessity for me.

Sure does make me drool to look at all the fancy laser cutters for making stencils, the PCB routers for making boards, and all the fancy reflow ovens and pick & place machines that are available now. All I need is a bunch of money. sigh...
