How small can you go?

Hi,

I've made a few boards with SMD components using toner transfer. Worked quite well for me.

I've got a few interesting parts I am willing to fry, unfortunately they came in MSOP package...

How feasible is it to create a board with toner transfer for MSOP?
Any useful tips?

Thanks.

0.65mm pitch? Absolutely. Just pay special attention to that area when you're transferring.

I wouldn't go much smaller though. I've done 0.5mm-pitch packages before but it was a bit tricky.

kt315:

Yep, they are .65s. I've read at some forum (do not remember which one), that for MSOP solder mask is a must. Is it?

c4757p:
Only for reflow soldering.

Ok, thanks a bunch.
