Recently I have started refurbing my companies extremely neglected Hollis TDL wave solder machine. After doing a general cleaning, de-fluxing, and de-greasing I have all the mechanical components back in working order. What i am left with is the elec

It seems that every time we do maintenance on our CP6 windmills, we have a lot of problems with nozzles sticking up inside the holders. It seems to happen for a while, then it goes away after we run for a bit. We follow the Fuji maintenance procedure

Hello Snr Tech, kindly isolate the problem if it's coming from the indentified holder or the nozzles itself, by swapping between holders. there will be oxidisation on aluminium, from which your nozzles are made after a period of time. impurities, sr

Try checking your Z height and also make sure that they are cleaned regularly. If the Z height is off your will be pressing your nozzles into the holders thereby causing them to bind up inside the holder. Replace the springs periodically since they d

Ya know, The weird part is that we seem to have a real bad rash of nozzle sticking right after windmill PM's. After the machine runs for a week or so it seems to get way better. Like 99 to 100 % better. This leads me to believe that it is not a Z h

Sir, reverse wound springs do help this situation. I would also recommend using acetone in the wind mills, its made of 440C SS and has R/c hardness of 58-60 you need to use something that will cut the gauling deposits left from the aluminum in the no

Doug, If you saw our calibration tool (Blue) it is for setting the head shafts off the machine. It probably is too expensive for small shops with a few machines to maintain. We sold them to three plants that were maintaining 60 or more machines. The

I�m surprised how un professional the so-called experts can be. After all we all had our start sometime and if you can never remember asking a un qualified question in your entire career then you probably have a bad memory. This is an open forum for

we have a HSP 4796, and have had placement issues with 0402's. If you can rule out global correction, rev'ed boards and a loose nest or a lack of support under the board. Look at placement before reflow. If alignment problems are present before oven

I agree w/ JB; the package height definition is crucial. I have had problems w/ this in the past, and found that a resistor height was being used as a universal passive height for the capacitor in question. Properly defining the height fixed the pro
