What is a soak test? Do you mean a recipe for removing moisture from a board?

Was it possible to calculate Soak Test Equivalent on PCBA? For example: Soak Test at 60C/80%RH equivalent to how many hour of test at 25C/60%RH ?

As long as you have a continuous profile with required soak and dwell periods, the zone lengths do not matter. For lead free, usually ramp to peak is preffered.that is with minimum soak (you can not avoid soak anyway. You can achieve the profiles irr

LSP is 'Long Soak Profile'. See http://www.aimsolder.com/tds/NC_297DX_Sn62_&_Sn63_Solder_Paste.pdf Looks like a variation of the RSS, with you guessed it a longer soak.

We don't know how to accelerate soak recipes. We'd suggest that you use the recipe for your product use environment that is suggested in SM-785 - Guidelines For Accelerated Reliability Testing Of SM Solder Attachments

What type of profile are you using (soak or straight ramp)? You may need to reduce the ramp rate or increase the time at soak. Jerry

Good afternoon, Profile your oven. Try to increase soak zone as much as possible. This must equalize temperature across the board and leads to prevent wicking. �Spike� as slow as possible after long soak. Do you use tooling for this PWB in productio

OSB ??? OSP !!! 1. The longer the soak, the fewer the Voids. 2. The Higher the soak, the fewer the Voids. Options 1 and 2 have downsides. You could call your paste supplier and see if they have a low-void solder paste... most likely formulated fo

Try this. Basic reflow profile build up and explanation of its parts: ramp-up, soak or no soak, peak, cooling. Good starting point.
