Hello all, I am having some trouble with the conveyor speed on an Omniflow 7 reflow oven. Recent profiling showed that the conveyor was running to slow so I calibrated the speed using the instructions in the manual. After calibration there was no ch

Water soluble pastes generally work best with a ramp-to-spike reflow profile. Check your paste manufacturer's recommended profile. There are many factors that impact your profile; board thickness, component density, buried thermal masses, board si

I am trying to optimize my reflow profile. i have a 5 zone oven. lead-free: for the 1st 3 zones, i am good, at about 150-200 deg for 150 seconds. during the 4th zone, i am at a temp of 200-220 for 50 seconds. during the 5th zone, i am at 220-245 f

| | I am looking for a rule of thumb regarding the maximum ramp standard components (chip capacitors) can tolerate without failure during the reflow process. The standard seems to be 3C\second, but this figure is generally derived from the average r

Hi Dave, Good to "talk" to ya again!! I have attached a photo of the antenna. Hopefully it will work its way through the system. The pictured antenna meets all our criteria. The defective antennae all seem to slide toward the center of the PCB (

Hello Doug, thank you for the additional commentary, it has reminded me of another reflow recommendation that I'd like to make in general for readers. It's not specific to O2/N2 in ovens but in the method for creating and managing profiles for numero

Takt time (without a google search) is the rate (amount of time per pc.) at which stuff gets made on an assembly line, a workcell, a hi-speed SMT line, CNC machine cell, etc.... Takt time is governed by the gate (the slowest person, machine, etc. in
