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

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 Small ovens work fine if the settings are correct and I seriously doubt 55cm/min is right. Profile it and speed down to around 35cm/min. Increase first zone to around 170 keep second at 208 but increase last to around 280 BUT profile to check it

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 All We have run SMT process with SnPb but we’re installing some lead free components like capacitors and resistor lead free. After the reflow oven all components have good appearance with solder join sheen. But the lead free components the solde

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
