The right way is to know what velocity numbers would net you the required flow for your oven and then measure with a manometer. The required velocity is primarily a function of pipe diameter (and blower rpms) but length and how bendy it is contribute

Shameless? In APE's experience not so - air velocity/power is extremely important in carrying energy to the board and close loop control of that energy is crytical in maintaining a controlled environment - if a machine design requires that air is for

“For a number of years now, work has been proceeding in order to bring perfection to the crudely conceived idea of a transmission that would not only supply inverse reactive current for use in unilateral phase detractors, but would also be capable of

Is this a Convection Oven or IR? If convection, you can increase the air velocity in the zones if the oven has this ability. You should do as Dave has explained. If you must use pallets when reflowing your components, you need to profile in the same

A little late but if this subject is still of interest the following paper from APE may be of interestwhen considering IR to Air Bath: HOT AIR versus IR and other convection Rework Systems HOT AIR is the most popularly chosen method of rework in th

Operation features of many devices, machine components, instruments depend substantially on state of their surfaces. Selective surface processing by high-intensity energy beam (ion, electron, laser treatment) is one of the most perspective directions

Yes, shameless. You could have come out and said that APE's equipment is the best thing since sliced bread but . . . you had to get all scientific with us. We already get bombarded by subliminal messages in commercials now, tech forums. In all ser

I disagree about the maintenance issues with tin/copper solder. All high tin content solders are hard on machines (silver or not). More dross? Controlling the back flow, front flow velocity and AVOID constant surface cleaning will reduce your dros

Hi James Short answer... yes... long answer...impingement velocity is excellent for heat transfer but it also is a higher risk of moving components. Variable speed blowers allow you to reduce the speed / impingment and more than likly your compone
