Good afternoon everyone, We have a customer that wants to specify "cleaning processes" on a board that typically has a "no clean process". Normally, I would not care, but I have one component on this board for which I question the cleaning process.

Are you gluing the parts to the board? We had a similar situation where the glue beneath the component would add a 'fulcrum' point to the center of the device and when the board flexed the part would fracture.

Is it only this 1 job? Is the error "board model not found"? I have had instances where I taught the Fids. and it still didn't like them in production. Is the board fid. in the center of the screen when you try to run the job?

have not given much thought on this i use old amistar machines as far as i know the fids are just referances to where the part is i dont think they would have to be centered up with the part as long as they are in the same place from board to board

Assuming you have the scale that corresponds with Board Width for center justified stencil. Formula would be: 2 x (distance to image {mm} - 368) = Board Width (setting on scale) http://www.dekhead.com/

I have some 13" long boards that warp considerably during first pass through reflow (no center support), what I've done to improve this type of warpage is stiffeners along the front and back edge. This may help with twisted boards as well.

It could be a blown fuse on the power distribution panel or a failed power supply. Check the power distribution board in the front lower center of the machine. There are 11 LEDs on the board and 10 should be ON

Open the rear door that has the cooling fans on it. Look at the wiper blade regulator, look toward the front of the machine about 8" or so and to then left 3"or 4". There should be a lexan cover/box over the board that has this pot. on it. If stil

In our reflow oven it has pins which move at the predetermined speed to move the pcb through the various zones in the oven. The forward row of pins is fixed along the front of the oven. The rear set of pins is adjustable per the width of the pcb. We
