The ideal cooling zone curve should be a mirror image of the reflow zone curve. The more closely this curve mimics the reverse of the reflow curve, the tighter the grain structure of the solder joint will be upon reaching its solid state, yielding a

Evtimov SMTA-Alex Hi After the comments, we have analyzed our oven curve according to our sheet of technical data of solder paste. We modify the curve taking the linearity to the maximum with what the file specifies, we attach the profile and the c

We make PCB assemblies for an RGB arc that is made up of multiple curved PCB's that have connectors on the ends to plug together. I think the end the radius of the arc is 2 feet. Jerry

Yes, I looked at the curve but it was high 250F max, but not higher than reflow oven temps..

We also just join multiple boards via connectors.

hello Evtimov Thanks for your answer. I will analyze the curve with our pasta supplier to reconfirm if it is adequate. It would also be helpful if you could share the tin lead curve profile to analyze. The location of the QFN is assembled by the top

For typical small sized circle LED panels, you can simply have a PCB routed to said circle... but when lighting fixtures are sizes 2-3 feet+, and a circular, typically how are the LEDs being spread across the radius? I can see flex LED strips being

thank you for suggestion but i need some more basic information i mean when should i use short tip or long tip, short is better to heat transfer but what about long one, there are curved solder tips what application? Kirk

I found the Mirtec got faster and faster to program the longer we had it. Both from a learning curve point of view and a building the library point of view. And it was reasonably fast to program at the start anyways.

I would second the hot melt glue method. You do have to teach the importance of "more is not always better" and there will be learning curve, but it's a lot better at securing big clunky electrolytics than RTV. It's also a lot cheaper than chipbonder
