BGA's ramp up rate in a convection oven

Doesn't make sense. Either your: * Oven is not operting properly [attach your profiler thermocouple to the baffle of each zone with a screw to check] ... OR * Conveyor speed is too high ... OR * Profiler is defective

Hi, Why are you worried about ramp rate on the BGA? Do you have a delta T problem on your PCB? Regards, Grant

The ramp rate of the temperature of your solder is more important than the ramp rate of the temperature of the plastic case of your BGA.

No delta T issues as I am not actually reflowing the component to the PCB. This is for moisture sensitivity testing as per JEDEC 020C Standard. Trying to duplicate a profile in the standard and am having trouble reaching a component ramp rate of 3

I am testing some BGA's (PBGA 30mm x 30mm) to evaluate the maximum ramp rate we can achieve in our reflow oven. Temperature is being measured at the body(top) of the component / not leads. After several trials (with various oven settings), the high

led tilt reduction by reducing convection air speed in reflow oven

Can anybody suggest how can I achieve good solderability in convectional reflow oven If I reduced Convection Air Speed 80%. The whole purpose is to reduce 0402 LED tilting in the convectional reflow and the PCB having QFN with 60 to 120 sec soak, 30

picture of the problem would help people to speculate what you do wrong

I am pretty sure, you are looking into the wrong spot. Your paste is too much, or your part has very inconsistent narrow leads(that includes wrong pad design as well.)

I agree with Evtimov. What he didn't point out is that the surface tension of the solder would vastly overwhelm any force from air flow.

convection batch ovens

Hi, I'm looking for a small batch convection oven that will replace the dryer section of a batch ultrasonic cleaning machine to dry off excessive water from washed PCB's, any suggestions for particular suppliers, will be appreciated. Jack
