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, bu

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. Regards, Jerry

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. Jerry

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

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

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

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 corre

Coplanarity also takes into consideration which is your reference plane. In the case of connectors, you can consider coplanarity between the highest and the lowest lead. Also, you can consider all the connector leads with reference to the connector

My answer will be another question actually: - Which defect would you like to see disappear first? (I am not even asking for the second highest defect because when you make the first one disappear, today's list might change anyway) Erhan
