HI !!! We have the same oven! and yes profiling is hard, but not that bad. Check with the solder paste company for information, right out of my head dont remember for the temps that we use on mondayIcan show you my profile so that youhave an idea

Let me be the first to suggest; Get a better oven. 5 zones minimum. If you can't, you will have to have some way of profiling the board. Does the oven have thermocouple ports? If not you will have to buy some kind of termperature datalogger. Mayb

Check with your paste manufacturer for a recommended baseling. The paste manufacturers generally have a database by oven that gives optimal performance for their paste. It's only a baseline, and does need to be adjusted based on the thermal foot pr

We have been having problems with proper wetting when running mainly lead free but also leaded solder in our Ersa Hotflow 3. Solder either often looks grainy or doesn't flow over the whole pad. This is generally the case when my profile is 170 firs

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

Hi, We have a 5 zone oven and we use a RTS Profile. Our last zone is the zone that the reflow takes place. some basic analysis is as follows: TAL 70 secs, peak temp 210,ramp rate seems fine. A typical setting is : Z1 140 Z2 160 Z3 160 Z4 185 Z5 220

Also Rehm Thermal Systems Ovens would be worth a look... They are well made, ALL stainless tunnel , 3 phase blowers, highly realiable, and they have new entry level series called VXC Series starting at 6 zones+, but based on same tech and build as t

For your operation you may want to consider this depending on the kind of boards you are doing. https://neodenusa.com/smt-reflow-ovens/neoden-in6 110V 3 Zone Smart Reflow Oven Neoden I don't think china ovens are truly industrial grade but you may

James: The ovens can be calibrated to help get this a little closer. In the computer box are 3 cards (alike) attached to the motherboard. They are called IPS-7 cards. On these cards are 2 potentiometers to calibrate the T/Cs for the heat zones. There

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
