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

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

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

I am trying to optimize my reflow profile. i have a 5 zone oven. lead-free: for the 1st 3 zones, i am good, at about 150-200 deg for 150 seconds. during the 4th zone, i am at a temp of 200-220 for 50 seconds. during the 5th zone, i am at 220-245 f

Just wondering if anyone has a Heller reflow oven and is currently or in the past use Tribol 1421 high temp chain oil. Thanks.

I worked for Electrovert for 20 years and up till today the 1421 is still the oil of choice. The chain doesn't care who's oven it's running in but it does require regular lubrication.

We use it and have had no issues on either oven. 1 Conceptronics, 1 Heller.

We have had some components that popped off in our IR oven. It was attributed to the solder paste. The humidity was above 60% the temp was about 70 degrees.

Good answer slthomas! This has got to be the biggest misconception out there. To perform SPC on a wave process you must first perfrom DOE to determine the critical parameters and or control limits. For example you will need temp reading devices tha
