Good morning, IR reflow is yesterday technology. IR heating principle has a lot of issues with heat transfer capability (shadow effect) and uneven PCB heating. To avoid this forced convection ovens were developed. Reflow oven for SMD soldering must

Just started doing BGA rework. After the removal of the "old" component and after site cleaning/component reballing I am ready to install the component on the PCB. It is recommended to apply flux or paste to the board/component. I would appreciate m

Dave, We have a rigging company that uses what we call airbags, the same principle like and upside-down air hockey puck. We have moved Fuji machines, verticle carousels (fully loaded with parts), reflow ovens etc. and wouldn't move another machine

Jay, I work for a company that manufactures batch reflow ovens however, I will try to be as subjective as possible. For the most part, what others have posted is true. Yes, there is one heating chamber and if the heater does not have enough power

I have observed solder balling for all aperture sizes tested. Solder balling levels appear to be better correlated against the amount of solder paste that is underneath the 0201 component terminations after placement rather than comparing this to th

I do not agree. We were even told that if we do not pay, and we need to order parts, that there is no guarantee of receiving the right part number (since we didn't/couldn't use phone support for correct part numbers) and if the wrong part was receive

John, We are using a well known solder paste, begining with the letter "H". (I don't want to be accused of advertising). Also, we are now using a board inverter. In the early day's however, before we purchased a board inverter, we were having to
