Hi All.

I'd like to do a little benchmark with you all regarding regarding the reflow speed. What is your highest reflow speed?

My own experience is 8.0 m/minutes using a 10 zone reflow machine.

Conditions: Mix boards (not only chip components, but also BGA) Medium to high mass

For those who ever done higher speed, 1 question from me, will the speed affected the part's position in the boards? Part become shaky and moved from the original position?

Hi Edri,

this is not a race here. Are you curing some kind of glue on your board? THe shortest profile I ever ran is for AIM solder paste - about 4 minutes total. with speed 8m/min your profile is going to be 45 seconds and I don't think this is the optimal condittion for any solder paste REgards, Emil

I think his units are wrong. We did a very thin board with some 0805 resistors on it at 80 cm/minute. This generated a profile a little over 4 minutes.

Hi Evtimov. Yes, correct it is not a race, but I want to know the experience of those who have achieve high speed. Because I ever read some study that mentioned the optimum slope (from room temp to peak temp) is around 1.5°. If I calculate this correctly, with my reflow machine to achieve this slope, I must use speed of 0.95 m/mnt. With this high speed, I worry it will cause the parts to be scattered away due to vibration of the conveyor.

Sorry for the typo error, my max speed is should be 0.8 m/mnt.

Hi Edri,

Unless there is something wrong with your conveyor there shouldn't be very much vibration. What little there is would not cause components to move around.

0.8m/min is a different story. I run my 10 zone reflow ovens with that speed all the time and never had a problem. For the short profile I mentioned the speed I used is even higher(about 1.25m/min). No issues with parts moving. Regards, Emil

We also run about 1.21 m/min on our profile, never had any parts shake loose.
