content: Hi, I'm looking for a dissent universal SMD board with footprints for SOP, TSOP, SSOP, TSSOP, small QFN packages and 0805 resistor and caps. I looked through ebay, but I cannot find a good size (100 by 150 or 200). Not all the footprints are necessary, buy I need something, that I can use for testing some new ICs.Can you help me find such boards, and not very expensive? Or maybe someone has made such a board and he can share the layout with us.Best regards,Lazar

content: Hi,Mike's one look great. But most of the sockets are placed around the center. And tha pads are combined 3by1, no 1by1.The other way is to have many different adapter boards and use the kind you need, combined with a big, only-holes board.Still looking for some decisions.

content: I'm pretty interested too. How do you guys order Mike's boards? Is it enough to pay via PayPal and await the package?

content: Yeah also received mine. Pretty happy with the product, cost and shippingbut the communication could be better(read: no answer, total communication black out).

content: Quote from: elektronchika on November 13, 2013, 06:31:59 amI have never understood why anyone would want a proto board with individual pads. It means every single connection must be made manually, and makes it difficult to remove & replace parts. Just plain dumb. For the rare occasions you need it for odd parts, it;s not a big deal to cut tracks.

content: Quote from: peter.mitchell on November 28, 2013, 11:06:08 amI primarily make these for my own use, and selling a few covers the cost, so I basically get the ones I use for free. They are usually sent out within 2 days and arrive fairly quickly, so I don't consider it worth the time acknowledging orders. Although I could just reply to the Paypal email, at that point I generally don't know exactly when I'll get to the Post Office to send them, and when I've sent them it's too much hassle to go back through emails to find the orders.

content: It was more to my PM here on the forum I got no response, as you can read in this topic it is not very clear how to order the pcb's for everyone and what to expectSo it is just my honest feedback, do with it what you like, anyway I sure like the product

content: These are not nearly as nice as Mike's design, but they might work for you. I ordered one, just to have on hand, seems to be of reasonable quality.www.ti.com/tool/dip-adapter-evmQuote

content: Quote from: JohnnyGringo on November 28, 2013, 05:58:30 pmIf you're gonna do that, just get some jumper wire and a machine pin socket...Somewhat related, if you do do that, i suggest getting a long roll of these;It may not seem like much but damn it makes life easy.

content: The TI dev board is a bit pricey at $10, but it does come with "Two (2) Terminal Strips (Samtec Part Number TS-132-G-AA)"www.samtec.com/ftppub/pdf/td.pdfWhat's that long roll in the photo called?

content: Quote from: JohnnyGringo on November 28, 2013, 05:58:30 pmThat sort of simple breakout is very handy for breadboarding with an occasional SMD part - I occasionally slip a few like that into unused PCB waste or tooling bars.

content: Quote from: notsob on November 28, 2013, 10:39:33 pmThe TI version ($10) contains 36 breakouts, compared to the 12 ($4.50) of Gerry's. Ti claims they're selling them at cost. But who really knows.

content: By the time you add international shipping to the TI product it's not so appealing, unless you can tack one onto an existing order.

content: Quote from: JohnnyGringo on November 28, 2013, 11:27:00 pmThey probably loose money on it if you calculate the processing/packing/shipping human costs alone you're easily at $5.- This is a steal from a commercial company, but then if there are shipping costs involved it's less attractive.
