One thing I have done in your situation is ask the customer if they have any older design boards that are similar in thermal mass or if they have any from proto work, etc.... Otherwise find/make a board of similar thermal mass as best you can.

One thing you should do is characterize your reflow oven, run profile boards of various densities, say 2 gm/sq.in. to 10 gm/sq.in. Adjust the oven settings for these various boards to acheive your standard profile based on your solder paste manufactu

I'm trying to find a source for a tilt device for use when doing touch-up soldering. Employee needs to raise the board above standard bench height for better access to the board and for better posture. Angle of the tilt device should be adjustable;

Hi Karkanov, Depending on how many devices they have, you may want to go spot solder with a laser system or light beam system. This worked well on some aluminum boards we did in the past.

I use a .059" copper clad sheet of FR4 that I bought from one of our board houses. It has not started to delaminate yet, and it has been through our ovens several hundred times. I am not sure what the life expectancy of a thermo-couple is. I am not 1

There are instruments from ECD, KIC and Datapaq that are used in addition to classic profiling for oven thermal management and they also have some very efficient prediction software for profiling. I am not an advocate of common profiles. Most boards

Hello, On customer want to make a aluminium board. It will have SMD Led on it. Like I never "played" with this before can someone tell me what I know to know on that new thing. What kind of reflow profile we need. What just I be aware of, is
