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

kindly send me your reflow profile ---and also the PCB lay out i shall able to determine your process flow on speed....and glue application i can be reach at this email- rdm@magictek.com.cn my web site is ;www.magictek.com.tw we are furance maker w

Hi. How one Can suggest you unless your Involment in your Process? Check Following Points and also Is Reflow Temp - Profile is as Per Glue Mfg. Requirment Are Glue Dot in Sysmetricl Position? Is glue sufficient , below IC to hold ? please visit th

looking for a bit of advice really, our current reflow oven (surfair 510) is in the process of slowly dieing so we are in the market for a replacement. I havent followed technologies on ovens for a while but im looking for something that is low to m

Not sure it's always a great route as the smaller ovens are going to struggle to get a perfect profile for a consistent result, especially on bigger boards with higher layer counts and mixed technology. You may want to take a quick look at a batch va

Just a comment on the Heller 1500. We had 3 at a previous workplace where we never made the Pb-free transition (this was early 2000's). The ovens we had were not designed for and were never used for Pb-free processing yet every one of them had all o

I am most familiar with Heller (10 yrs. of 1088 4 zone - 1800 8 zone ovens) and find them to be very reliable. Other Manufacturers may have five zone ovens on the used market. (I used Petlock as an example because you could get data sheets/specs from

Yes, it is time and temperature, but it is also speed and distance. Even though you can run a longer machine faster, the boards have a longer distance to travel and you do too, so the cycle time per board may not improve be reduced as much as you th

An 8 zone oven will give you better thermal control over the whole process. It's useful for lead-free soldering, or for boards with varying thermal loads/shadowing, etc. You can make a 5 zone work for lead free, provided the boards don't have signi

Hi everyone, Our QC manager is bugging me about calibrating the TC readings on our reflow ovens. I keep telling him that doing a regular reflow profiling with a mole is sufficient to see if the oven temperature are normal. The manuals state that TC c
