We found used Ersa HotFlow 2/14 reflow oven that does not have bottom side preheaters. Can it be easily and safely used in normal high mix/low volume production or is it built for specific products which does not need bottom preheaters?

That model comes standard without bottom preheaters. Bottom preheaters are an option so I would think it is designed for general use unless you have some very thermally challenging boards. As long as you are within the process window, you'll be fine.

hi all What do you think about soldering pb-free in reflow oven (air) lenght 1,7m (5 zones top,bottom) with max zone temp. 300C? Do you think that this process will be stable? Our max PCb dimension 260x260 mm. When i compare different oven producer t

Ken, thanks for your answer, it is much better presented than what I was fed by our qc. By "calibrating TCs" I meant the readings the controller is displaying on the screen. So that would be the converter that we would check and calibrate. Thank you

Hi, I have a small assembly line that consists of a Semi-Automatic Stencil machine, a Samsung Pick and Place, a small IR reflow oven and a wave soldering machine. The reflow oven is presenting the biggest bottleneck. The machine is a small IR (T960

If I read this correctly you have two identical ovens that were setup the same ie zone temps, fan speeds etc... when you ran the same board through each of them one showed a lower board temp. Is this correct? Is the temp of the board 7 deg. lower t

Hi, I have been looking around for an 8 zone reflow oven with convection heating top and bottom and computer control for setting up and storing profiles. The Chinese company "Jaguar" have a couple of models at reasonable price that look like they wo

I have seen this before. Check: --Vibration of belt --Interference (part getting "brushed off" while reflowing bottom-side components --Some glues' cross-linking mechanism is impaired by the flux during migration in reflow, redering the glue useless

Can anyone give me a contact for someone who sells used vitronic reflow oven parts. I am look for heater panels or heater wire for a vitronics smr-820 reflow oven,or some place that can replace the heater line in them. Thank you

Basic rules: 1. The longer the oven the better(if you have the space)- better temp control, better repeatability, better throughput. 2. Only convection - don't get IR heaters 3. Buy reputable brand machine
