Hello, The oven profil is not the solution! The only solution for the solder mount on the side is to put gel flux on the side of qfn and make a second travel in reflow . The flux remove oxyde from the copper that is not tinned and the solder is able

Sebas, I suspect that your finding of needing the fillet for the card to work is a false finding. One that I dealt with for many years in assembly. As a bottom terminated device, a fillet to the side terminals of the device is not required. Adequ

SR. Tech: I have worked with Omniflo 7 and 10 ovens for many years. I purchased several 10 zone ovens in '98 when I worked for Ericsson. Here are some of my experinces with Electrovert Omniflo ovens; Yes, you can expect to run the conveyor speed a

Hi there I have a question about reflow oven for Pb-free technology. I've noticed that some of the manufactures offer reflow ovens with short (26-30 lenght in cm) heat zones others offer longer more then 30 cm. So there are ovens with total heat len

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

I have used the Chinese ovens that Manncorp is selling bought from another supplier and they can do the job. These will do the job. You can manufacture metal piece(plate) slightly tilted to collect the boards behind the oven(similar to wave soldering

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

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

I use a lead free 3 zone essemtec oven which I love. It's on the smaller side (wish it was even smaller). It works fine in our application. Maximum width is 300mm and only uses 5-6kwh average (25A max). Made in Switzerland. For some reason I don

It's all about temperature versus time. The longer the over IE more zones the faster you can run. That doesn't seem to be the case for you so a 5 zone running a little slower will work. What many forget is that oven manufacturers can recommend what w
