Questions are: * Does the component take solder when you dip it in the solder pot to test the solderability of the leads? * Can you get full barrel fill when wave soldering a bare board? * Is your flux reaching the top of the board through the hole b

So others can solder the same board and part but you can't. Dipping the legs in flux doesn't help. Then it's either your pre-heat or wave. Measure your pre-heat and compare to others or flux mfger. Do you have chip wave or something like an Omega

You are right, RSS profile is not the correct description. I am using a profile which heats up quickly to let the flux spread. Next linear up to activate the flux and prevent thermoshock. My experience is however, that small changes in this profile

Still confused what you are trying to say? And I didnt get the answer regarding soldering profile.

Answers: The component does take solder, no problem We get a full barrel fill with an empty PCB but only on one of the holes, the other hole has so much copper around it. The flux reached the top of the PCB when I tested the empty PCB. The IPC-A-610

Ideal situation is get a technical rep from the solder paste supplier. They know their paste better, and should be able to work out a profile based on their paste and your oven. Again, a technical rep, not the sales guy.

..and he can put the flux in and keep it a secret too from his customer.. RSS profile on wave?? I never heard of a soak zone for wave preheat...you may be burning off your activator..hence, the beads. For wave preheat, your main goal is to ramp up

Sr. Tech, you are right in that there is no verification of the profile. We are a Class 3 high mix OEM. We have visual inspection after SMT. We have not seen problems with wetting, grainy solder, cold solder, charred boards, etc. that would indicate

SAC305 Will be the best choice with minimum TAL, Maximum Soak Solder Profile. Surely your solder Joint strength also will be more reliable & This can pass any kind of reliable Tests.

Nice to have you back on SMTnet. Some of the newer folk have missed-out on the solid contributions you�ve made to the Forum. The chicken wire cleaning basket was a classic!!! [It�s a shame that the folk at SMTnet can�t recover those files.] We bu
