Yeah, perhaps lean more towards a ramp-to-spike profile - reducing the soak time and add a littel heat to your temp above liquid. This has worked for us with water soluable paste as we are not required to use no-clean and utilizing a 6-zone oven. G

Time and temp in lead and lead-free reflow

You can keep only the 5th zone as the reflow zone. And lower the first two zones to keep a good ramping rate. Meanwhile,please note the ting temperature in software or control panel is not the exact temperature in your PCB, you'd better get a KIC or

What paste are using? You should referance the manufactures time and temperature specification. Running lead-free in a 5 zone oven can be done with out a problem but it is not production friendly. If you are concerned with through put I would look fo

I am not very concerned about production time, but it is always a thought! Quality is more importnant of course. We have 2 different pastes, with almost identical requirements. We can get close to their profiles, but i am worried that i am spending

Has anyone got any of these ovens or know of any issues with these? We are on the market for a 10 or 12 zone oven and the BTU above is looking like the favourite Any info would be great

I like MpM personally - run forever and programming is easy and leads you through it. It's hard to miss a step of programming with MpM software. DEK's a little harder (for me) but still very nice controls. The pluses of DEK - DEK has a high freque

I agree you are too cold for the profile get it up to 230C and possibly allow it to dwell a little longer in preheat as opposed to pushing up the reflow zone only. Sn90/Pb10 melts at 220C so 2C hotter than your profile so you are reliant on it alloyi

Here's my 10 cents Studies done in the 1980's concluded that pure tin was prone to whisker generation. A tin content lower then 70% became exempt from this phenomenon. I have never seen or done any studies on the impact lead had in reducing the pote
