Hi Zac, My 2 cents: We had similar problems on a board in the same situation (tin-lead HASL, very long leads, low pot height, high pump RPM). Trimming the leads shorter, moving the pot closer to the board, and dropping the pump speed down to sane

Thanks for the replies. The single missed lead is a bit odd - we usually have an entire area missed and that's due to the board not sitting properly in the pallet fingers. I figured in this case it was likely due to poor fluxing? We have always str

I assume your oven has a "board width" setting for every board and the conveyor width is automatically adjusted as soon as you select the profile/recipe... For the double sided reflow boards, I would set the width 1 inch (or another rounded amount)

G'Day All, I have a couple of new Panasonic MSR's. Whenever I load a new program into the machine, I have to manually feed the first PCB onto the X/Y table to get it to run. After that, they run just fine. Panasonic is going to be in and they hav

Dreamsniper, The optimum contact (dwell) time in the wave should be 2 seconds. Contact band width is a function of conveyor speed. For an example, 5cm of contact band width at 150cm/min. conveyor speed will give you 2 seconds of contact time and 2cm

I dealt with the same issue for a month or so. We jumped through a lot of hoops, replaced both lead screws, verified the motor was good, a ton of stuff. Ended up being an intermittent wire connection between the control board and the conveyor width

Hi, this is not a solution for your o-ring "belt" problem but a guideline for the future on an o-ring "belt" (wrong word as it is Not a belt) conveyor. These crazy O-rings have a small radius which makes it somtetimes hard to do a conveyor width adju

Process Trials Procedures. Standard trials are often conducted on reflow ovens by production engineers during product assessment, machine approval or in process set-up. The following trials are also used by machine suppliers during equipment develop
