Hello Sid: i don't know where you bought the machine. the central support system is an addition part, it is specially designed to prevent the PCB board from bowing. i know that the wave soldering machine which made before did not include this useful

Not sure what's in your line equipment wise, but you need to know relatively what kind of placements per day you run regardless of the mix. We run around 1.1 million across 5 lines in 3 shift. Calculate what kind of placement per day on a specific

Thank you very much for your reply. I do have the numbers for placement per hour, but, I have some concerns on it (forgive me if it is a stupid concern, as I said, I am new in this field, and trying to figure out this business). For example, it is

I purchased a used QUAD 4C -136 and after a few months got the machine running 8 hr shifts. One issue I have come across is feeder drift. I kept re-aligning the feeder pickup positions but they would always change. Finally I got the time to measure

Sean, We can't comment on the EDX report; but, we have seen these types of problems before. We would initially agree with you that it seems like a material issue. A solderability test should be performed on the part, and on the board. Easist way

Hello, this is my first post in this forum, but sometimes I visit it to get some news. Now we have an issue and I need your advice. Few months ago we were awarded with a project that use PTH components. We solder these components on Wave soldering
