What is the difference of formulation No-Clean Sn63 with No-Clean lead free paste? Is there techniocal data in detail for performance property of No-Clean lead free paste (for example, viscosity, solderability, tack, print life, reflow profile)? Is

Hi Everyone, I am just curious, is there a guidline that people follow for choosing their lead-free solder paste? In other words, how do people know whether they should use Indium alloy, or Castin (Sn/Ag/Cu), or whatever else? Thanks

The solder paste formulation is different 63/37 is a tin lead alloy so t here is one difference from a lead free. Yes you can get no clean lead free products but if you compare the amount of visible residues they will be normally higher. So far most

Use the thermal recipe suggested by YOUR paste supplier, as the starting point.

Could you tell me please when the lead free solder regulation will become mandatory in Europe and also what are the current industrial alternatives for paste, bar and wire. Cheers, Jack

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

As we have vitronics oven(SMR610A) made in dec,1997,which has 5 heating zones and 2 cooling zones. For Lead free soldering what should be our baseline for low/medium boards.we have gathered profiles from various paste manufacturers,however we don't k

Hi Armando, I think you have to buy a bigger reflow let say 7 zones to get the correct profile. The reason you are getting that problem is due to short profile time. What is the size of your board? What is the composition of your solder paste? Ple

There are two profiles available for the Pb-free process: (1) RSS and (2) RTS. In your case, you should try a solder paste that supports RTS profiles. A minimum of 7 zone Refow Oven would be fine on the Pb-free process. However, you may still try by
