One per operator is the optimum for obvious. 3 to 4 per operator is more typical. The number is not as important as the type and time. Like don't have someone handle 2 different TO92 part nrs., splitting them up to different operators eliminates the

We are building class 3 products, using no clean on wave and selective solder machines. Both processes are producing micro solder balls between the leads of through hole components. I have searched the site and haven't found any recent threads on h

Besides changing fluxes, do you have good knowledge of actual flux volumes? Do you have a micrograms per square value? Pre-heats can affect flux by burning off too soon and also not enough - therefore moisture hits the wave- how's your humidity cont

SORRY I did not offer a solution so here goes - The best way to get rid of this issue if you cant change flux is to reduce your flux consumption to a minimal with a spray flux and keep the heat REALLY high to boil off the alcohol before it can be abs

Patrick, you're right. I've only dealt with 2 different flavors of Alpha alcohol-based flux. I've always thought that the convection causes the activator to evaporate more rapidly, but this is probably just the case with older formulations. Again,

I found some machine manufacturers put convection nozzles in line parallel with each other instead of staggering them so you get a nice parallel line up the board where there is no flux be it no residue alcohol or VOC Free. The best I could find was

You have my sympathy, the Line computer Station configuration screen is hard to get your head around. Assuming that you have configured the station correctly you might need to re-compile the station and/or consistency check it to see of it passes.

We believe that tip tinners reduce the life of the tip, also. Why do you use such a product? We like using solder paste to clean solder tips. Place expired solder paste in a covered container. Open container and dip the tip. It comes out clean and s

Hello all, Long time no talk. We just happen to pickup a XP242 the other month and like it so far. Well we have a question for you XP users or anyone that can help. There is a MFU on the XP and I was wondering when the operators pull it out for setup

Using larger pads on the corners is fairly common to improve self-alignment of BGA and CSP. For example, "9.3.2.8 Large corner pads and overprint The self-alignment of BGA or CSP can be improved through a design change. By utilizing a large board pad
