From: Joerg on 28 Nov 2009 15:39 Gents, It's been more than 10 years that I needed this but when looking I found that nowadays companies do not stock any very tiny coax. Almost like vaporware along the lines of "we'll make some if a really fat order comes in". What I need: Coax with an O.D. of 400um (0.015") or less, low stiction of the jacket, impedance is secondary meaning we'll have to adapt, must be easily solderable so no aluminum shield. Is that available off the shelf or for reasonable (up to the low four-digits) NRE somewhere? -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

Tried Joy Signal? Or Micro-Coax? Any chance you could use a flex pcb (Minco or some such) instead of coax? The cryo guys, LakeShore maybe, make small coax too. John

You could try asking these guys: http://www.schleuniger-na.com/DesktopDefault.aspx/tabid-46/89_read-525/ They seem to make the tools for it. Joop

But it'll be expensive because it would need to be coiled for flexibility and then we'd need a 5-6 ft stretch. Typically anything above 3ft gets to be super-pricey. > The cryo guys, LakeShore maybe, make small coax too. > Thanks, will try. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

Not only that, but we'll also need one of those machines. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam. Use another domain or send PM. |
