interest checking,smt to pdip adapter boards

[digi01]

hello everyone,
by reason that smt ic is very common around world,I am going to make some adapter boards for myself.I wonder if anyone want them?If there are enough interest,I can make a group offer.
I am not interested in making 8 pins smt to pdip adapter,because it is easy to resolve by diyer.

here is my idea:
1,SSOP 28 pins to PDIP adapter,it is very generic(example,TI's dac chips,buffer ic).
2,QRP 48 pins expanding adapter(example,qs7785)

any comment are welcome

Hi Digi01,

Was hoping for some 14pin adaptors

like the Brown Dog 050101. So I could

do a TL074 upgrade that seem to be

in lots of places such as my active

crossover. Maybe as you do work on the

project you might be able to offer a

board mix with 8pin 14pin 28pin Soic to

dip converters. Like a rescue kit for

buyers of surface mount components who

still have dip board. Just break off the ones

you need to do the job. Six of each on each board.

End user does the connecter pins.

Good luck with whatever you decide to do.

Try digikey , they sell some smd to dip/sip adapters.
SOIC to DIP for example , from Aries Electronics.
Better to search with their printed catalog.

to Vidalgo,
I have search digikey and the other resources,there are only photo boards but no adapter boards.Brown Dogs is a bit expensive for diy hobby.

to AnthonyPT,

Hi Digi01

As you say; a lot of these commercial

adaptors are inclined to be expensive.

Cimmaron and Soundlabs group both have good info

and pictures of what is available.

here is a roughly idea.the rescue board(kit) include:
2 pcs of SO14 to 14-pin DIP adapter,
2 pcs of SO28 to 28-pin DIP adapter,
3 pcs of SO8 to 8-pin DIP adapter.

I have ask for local manufacturer,the price is around $4USD per kit.

Hi Digi01

I have just been thinking about some
other options. Adaptors for those
using OPA627s who want to use them in
a dual or quad application. So either
all surface to dip or maybe in a duo
dip to dip configuration. With bypass caps
on board for the power? Sounds good that
you have found some gold pins.

Zang, I'll adwise you to increase the traces a bit, 20-30 mils and add decoupling caps, 0805 types for the SO08->DIL08 adapter.
