Northeast Machines- For a machine that is 16 years old the best thing to do is contact Suzuki direct. I asume it is a TAB Machine. I know most of the time people hate to be refered back to the OEM but in this case it is best. www.suzukinet.co.jp For

Can someone explain what ageing means in terms of chip caps. Capacitor vendors state 7% per decade hour or 2-5-1 per decade hour. What does this mean? I think capacitor values lower over time but what is a decade hour. Thanks, Chris

You did not tell us which brand machines you are using. I do assume that you mean the feeder position recognition of the Siemens machine. Did you ever re-teach the fiducial # 250 and 251? Can you narrow your problem down to some particular feeders?

IPC-FA-251 recommends 121*C for 30-60 minutes for 1 and 2 flex layer circuits. A rigid flex can take easily an hour per layer depending on the construction.

All, Thanks for your quick response. However, my primary concern is not the question of solderability advantages of nitrogen versus air. With all things (zone temps, track speeds, flow rates, etc.) being equal, what would be the profile differences o

I used to switch my N2 on and off for different products and I had performed profiles on the products with and without the N2 on and there was not a difference in the profiles. So you should not have to adjust your profiles. I think everyone else c

Hi, Since you're looking information about flexible printed circuits,a book entitled "Printed Circuit Boards R. S. Khandpur" could give you lot of information about flex circuits from Design, Fabrication, and Assembly Phase. The book contains compr
