Wave soldering preheat temperature

I'm not a Wave soldering guy and my friend have asked me a question on what is the best preheat time and temperature for Wave soldering.They experiences only 10% flow up thru the PTH barrel. I've asked them to increase the temperatue to 120 Deg C. Cu

Hi , As far as I experienced with wave reflow. If u have a refective thermal reader , u will see that the board is exposed to much more temp than the 120 deg that u set. Actually , once u see the board warp or comp. crack u should know that

If you will place a temperature strip on the board during wave soldering process you will get a max of 210 F or 98.8 C which is normal on the standard wave temperature. The problem on the 10% solder on the TH via hole can be caused by insufficient fl

SMT Experts, Hi, I have a pondering issue, which is : Our current specified Reflow preheat timing is a necessary 100~140sec for the ranges of 100~170Deg-C....obtained timing is 77sec... out of curiousity, if we further fine tune the obtained reflo

preheat slope vs ramp up- what is different?

I am doing the case study of the component chip 0201 tombstoning problem. The significant causes was the reflow profiling preheat slope or ramp up rate. I really can't differential between preheat slope and ramp up rate. Could anyone here show me the

Please follow the paste suppliers specs for the paste as an indicator.Most people think that if they follow the paste suppliers recommendations to the T it will be a perfect profile but this is not the case.Play around with preheat settings but follo

Thanks for the information about the reflow profiling its really useful for me to set up my own profile.
