I would always have top and bottom preheaters in a solderwave machine. Even if you can make it work without them, it's better to heat both sides of a board then just one. Far less stress on the parts you are soldering. Plus you may need it one day fo

Try swapping XWB board that is on top of X-Wagon. Have you try that? All signals go thru there. Another thing can be those 2 ribbon cables that are behind of X-Wagon. How long ago did you change them? What I would do is to move X to different positio

It looks like one oven is 10years newer than the other, so if we assume same maintenance routine you should get another 10 years if life on it. On the TH side, you know your board complexity - for me wave have much more value than a Selective. Selec

This happens with either old tape, the cover tape doesn't stay sealed on the left side, or is the seal is too far to the right, the knife lifts the cover tape. There isn't much you can do in this case. Your choices are: switch the component into an A

You are programing something wrong or your image is not in the center of the stencil. On DEK machines you can move a lot in Y by offseting the image in the program. In X machine can move +_5mm. Now, sometimes there is a way around this as well if yo

I'd have thought that centre search uses an algorithm to find the dead centre of a specified geometric shape. Pattern recognition basically has a picture of the area of the board selected and tries to match it with what the camera sees. ( so it doesn
