The noise kit I'm referring to involves the installation of a new interface card in your PC, a new sensoray interface card in the card cage (brd 7), soldering/bridging of two DC COM points and new DB cables.

Had the same thing happen here. If the thermocouple line shorts out the temperature appears to go runaway (999F or whatever the max of your software is). Ours was a short out in a socket where the thermo plugged in to pass through the frame. Regar

Good Afternoon, We are using Kester 520A. It has worked well for us so far. Good Luck Chris

We are using tin-lead solder. The components could be lead free components, they probably are. I will check the plating on the components and investigate changing it.

Wagoner, Try switching to a transitional paste designed for no lead parts on a leaded board. Running your current paste at higher temps will dry out your flux too soon, which may be your problem.

You should have no problem using lead-free components with tin-lead solder. Is your reflow oven IR or hot air? If you are using an IR oven and the components are white or light colored, they may not be heating up enough for the solder to flow on

We reflow with hot air. Our peak reflow temp is 220 to 225 degrees C. Thanks for all of the ideas.

Print your paste onto a ceramic tile, place the offending component onto it and send through the reflow oven; then observe the results. You will soon see if the component is solderable!

I am looking for any comments as far as the JUKI 2050 or 2060 placement reliability? Does anyone have experience with these machines and could give me their input? Thanks
