Can anyone tell me what makes the wave solder machine lead free? I I am looking to buy a used machine "electrovert minipak 300" and they are claiming that they can convert the machine into lead free. I want to know what does involve to do this kind o

I want to know the advantage of using complete inert soldering wave machine (with Nitrogen, Tunnel concept) in comparison to use just a soldering machine withe inerted solder pot. Thanks

Lead-free means expensive tin. Tin is an excellent solvent. So, metal parts in contact with molten tin must be expensive enough to resist that nature of tin. To learn more about this: * Search the fine SMTnet Archives * Look here: "Liquid Tin Corrosi

I am doing lead free testing on a Vitronics selective machine with a 4 mm nozzle. The finishes I am testing are ENIG, ImSn, and ImAg. The problem I am encountering is achieving good top side wetting. Has anyone had any luck with this type of an ap

Check flux penetration and type of flux. How much is solid contents. The solder filling is better under Nitrogen. Check the time (speed) of the nozzle whether is correct. Usually For SAC305 the temperature of bath is 320C/degrees, but only for sel

Hi Armando Hotflow 7 is a big machine and one of the best Reflow ovens around (in my opinion), well suited for Lead Free. A typical 1.6mm board has the following settings for Lead Free SAC305 paste All Temperature settings are Top and Bottom Prehea

We are starting a lead free line. My question: Is there a contamination issue with running lead free boards and lead boards after soldering through the same board wash machine? I would expect not it, but want to know if anyone has any experience with

Sn corrosion effects were studied for stainless steels, coated stainless steels, titanium, cast iron, and other materials. This study can be found in the SMT Library under "Equipment Impacts of Lead-Free Soldering" Electrovert uses a Melonite coating

Great as most Lead Free machines have the wrong angle on them 7 degrees is correct. So you are still exiting the wave in the middle of the pot then.

Have anyone perform wave soldering on FR-2 and FR-1 printed circuit board with lead free soldering? Can you share the parameters(wave temperature,preheat temperature, contact time, wave height,etc,) used and did you do any changes to the wave solderi
