I have an Electrovert UPK 660c fitted with IR preheats top and bottom. We assemble a large range of multilayer backplanes and I was wondering if there are any advantages in changing to convection preheats.Has anybody got any views on the subject.

Here's a good IR preheater that you should look at: www.paceworldwide.com/products/smt-rework-systems-and-preheaters/preheaters/ph-100-low-profile-pcb-preheater

A key factor is underside Pre Heater ----- Conceptronics makes the best in terms of IR Preheat----- Most machines have forced convection from the top and bottom --- the preheater is the key on larger more dense boards. Placement accuracy is also bett

Which wave solder flux are you using and what types of preheaters did you have on both your old econopak and your new vectra? From my past experience, an alcohol-based flux does NOT work well with Convection style preheaters....the flux burned off t

TYPE of Preheater makes a HUGE difference, as well. Infrared (IR) and convection, 2 of the most common types of preheaters, have very different heat transfer characteristics..... Convection heats your board more uniformly, so you'll see very small

HI, just my 0,00001 cents Which preheat system does your wave solder has? for instance ? - IR ? - Bottom only ? - IR + Forced Air ? (bottom) - IR + Forced Air (bottom) IR top ? PCB thickness ? Appropriate preheat is important when looking to f

For that price you will find some chinese ovens which will be probably mixed IR(for preheat) and convection zones. If not you will have to go for second hand equipment. Both will work for you.

I have an Electrovert Ultrapak 445 Wavesolder machine with 3 IR preheat zones and a single wave with omega wave. I want to run a DOE (Taguchi) to determine the optimum settings for soldering both single-sided and double-sided boards. Can anyone po

My own preference in this arena is towards the forced air convection style preheat, the key being the forced air. Radiant preheat is too slow for some, and IR preheat can have other issues that convection (or radiant) will not. Zephyrtronics has bee
