We have been having problems with proper wetting when running mainly lead free but also leaded solder in our Ersa Hotflow 3. Solder either often looks grainy or doesn't flow over the whole pad. This is generally the case when my profile is 170 firs

Hello! I am having trouble with the new changes from lead joint to lead free joint, we are working on change to lead free, I am using a 3 zone oven reflow, the zone temps are : zone 1 zone 2 zone 3 (top and bottom) 128 208 260 th

As others have said, you'll have some difficulties getting good reflow on pb-free out of a 3-zone oven. We did it with a 4-zone for awhile, but only had really good success on low thermal density boards. That said, you should definitely check your

Hi Russ, Thanks for that. The oven was being recommended to a customer of ours who is a subby, so will have to handle many different types of boards & components. I was thinking this wasn't too great an idea but thought I'd go for a second opinion

Hi, I don't know if I'm being naive, but I'm seeing a number of 3 zone (+1 cooling) ovens on the market that claim to be for Lead Free soldering. Trying to follow component & solder manufacturers ideal profile can be tricky with 7 zones at times so

Hi Ronald, We have both, 2x calrod on our leaded delta and calrod/convection on our leadfree, both are IR in 3th zone. Indeed, the forced convection is way more efficient, we can run it at 100deg C, where we would need 300deg C for the calrod for t

These sound like european machines, From what I can tell so far Lead Free capable ovens just mean that they have hotter heating elements, and blower fans that can take the additional heat supposedly. It does not appear to have anything to do with t

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

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

Hi, Bill, Lead-free solder and paste manufacturers will be a great resource for you during the transition; they've tested their products extensively, and their application groups have been able to help me through the biggest changes. There are a fe
