Hi Patrick,

How works the Proctractor for your TT?

Don't worry I will be patient, about price 1€ is for each strip or for each adapter?

Thank & the best, Felipe

Michael,

Will also work, but at such find pitch you need some PCB supplier to do it for you, and we just don't have the quantity.

Also for me the tracks are unnecessarily long and too different for one FET to another. Cutting the 2 legs will take 5 seconds.

But if the others think it is good, go ahead and get a quote by all means.
I shall most likely stick to my own design for my personal use. 🙂

Felipe,

8 Euros it would be for a strip of 8.
Postage & packing alone is 2.50 Euros or something like that. I have to count for those who order 1 strip.
For making the board, I need to print 2 special PCB transparencies, etch one 0.8mm board, do solder mask, pre-tin, post-bake, ..... Including all the organisation work, at least 3 hours.
My hourly rate at work is 3-digit Euros. So I am actually the wrong guy to do this.
You have my blessing to use my design freely if any of you would want to take over.
I can send you a PDF file by email for the production for the group.


Best reagrds,
Patrick

What to do ?
You redesign according to my layout and organise a board to be made for all ?
Bear in mind you will need 0.8mm boards if you want to use standard 2.54 pitch header pins.
If you get a professional board made, and they can build in snap grooves, you might be able to get 16x10 adaptors out of a 160x100 Euro card.

So If I buy 3 strips x 8€00 = 24€00 - 5€00 postage & packing 2 strips = 21€00?

Michael,

No need to bend, but you might need bigger holes:

SL 1X36W 2,54 Stift- & Stapelleisten sowie Jumper - reichelt elektronik - Der Techniksortimenter - OnlineShop für Elektronik, Netbooks, PC-Komponenten, Kabel, Bauteile, Software & Bücher - ISO 9001:2000 Zertifiziert

6USD for 10 is OK (incl VAT ??).

Pins are 0,64mm square, that's too big. We have 1,27 mm hole to hole - min 0,6 for annular ring - 0,15 distance = 0,52 max hole. Otherwise I need to move the G1/S2 pads a little up.

Here is the alternative: http://www.knap.at/datenblaetter/ste/ste_wpp_164.pdf

will the 0.62mm sq pin push through a 0.52mm diam hole?
I can't think how firm a push that would need for 6pins to force their way home.

Are you going for 0.1inch pin pitch or 0.05inch pin pitch?

@ 0.1inch pin pitch you have plenty of room.

Andrew, a 0,62 mm square never goes through a 0,52 hole 😀
this needs 0,9 mm hole. For use in a regular "389" footprint
pin patch must be 0,05 inch. The best way is to use the pin-header
from here http://www.knap.at/datenblaetter/ste/ste_wpp_164.pdf.
Those have 0,5 mm dia pins.
I sent a qoute to that company.

If anyone else know where to buy, pls. let us know.

Michael
