Is anyone wave soldering 0603 leadfree succesfully? We have no problems soldering them leaded, but lead free we see a lot of random skips and some shorts. We use SAC. We have tried different fluxes, flux settings, playing around with preheat, sol

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

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.

Every problem faced with (all) lead free alloys can be solved with 2 words �add lead� I'll keep it short don't want to sound like a broken record.

looks like my knowldge preceeds me again. I woud try a different flux. If it doesn't work - it will take a question mark away and your one step closer to total success.

you need to check your angle on this, can you measure and advise what you have cheers Greg York

The angle is a standard Soltec 7deg. We don't have the tools to measure this accuratly, but I do trust Soltec on this.

"Solder alloy compositions are numerous but the most important are still the tin lead solders which were used by the Romans. Tin melts at around 232�C and lead at about 327�C in the combination 62Sn 38Pb the resulting alloy melts at 183�C. This compo

Hi, The bath is titanium coated, and the machine is only 2 years old, and was designed for lead free, so we know we don't need to change anything. The reason the supplier gave for suggesting the bath change is "other companies are doing it" and it'

Hi, We are about to change our wave over to lead free solder, and it's a Soltec Deltawave, which uses about 750 KG of solder. Our supplier is recommending we change the bath over, however that seems a bit extreme. They are concerned we won't get ri
