question about DIP package and SMT adapters

I'm trying to work on a circuit on a standard perf board I got from radio shack... and it works fine for all the DIP chips I pick up from radio shack... but, I need to start using some cooler stuff... but I'm finding most of these come in all sorts of SMT packages...

My questions...

1.) I've been able to find TSSOP to DIP adapters, but I there's two options on DIP 300mil and 600mil... does anyone know which of these is the regular one I'm use to?

Here's the adapters I've found:

2.) The ICs I'd really like to use come in TDFN, UMLP, and MicroPak10.... I can't find any adapters to these... does anyone know of any adapters or work-arounds that I can use to still be able to prototype and play with the new ICs that are coming out?

Much Thanks

The common small DIP package (20 pins or less) has lead rows on 300 mil (0.3 inch) centres. 24 pin and larger packages are usually 600 mil wide (0.6 inch), but you do sometimes see 24 pin parts in 300 mil packages.

ahhh... cool, thank you answers my questions, and thanks john for the link, those are cool

the number is the width of the chip 0.3 inches or 0.6 inches most chips with fewer than 20 pins are 0.3 inches wide (between rows of pins).

if you're going into perf board both types will fit just fine.

draw up what you want with a PCB drafting tool and send it to a PCB maker. some PCB makers offer free samples to new customers.

or glue the chip down and solder fine wires to the pins (eg:individual strands from tinned hookup flex)

Once upon a time, i made and advertised an adaptor that would accept the following SOT packages: 23, 363, 457, 563, 753, 353, 143, 26, 25; SC-59, MiniMelf, SOD-323, SOD-123 and SOD-523. Solder the part on the board and plug the assembly into a standard

8-pin DIP socket. As a computer without power might say, "no bytes".

There are some PCBs made that take a "reasonable" variety of SMT parts and have workspace for breadboarding; they ain't cheap, so if you are going to do a lot, lay out your own board and have Sierra Proto Express or other decent board shop make them.

If an sm PLCC is an option, you might want to consider these. PLCC sockets are available with at least 84 leads with pins on 100 mil centers for inserting into a perf board. They are a little touchy in the bigger sizes.
