I might be able to help. I�ve been manufacturing in the irrigation industry for around 20 years. If your retailing for $20.00 your cost should really be around $4.00. If you would like We could discuss p.c.b. layout, enclosures, packaging, & marketi

Omniflow reflow blowers going bad ?

Electronics Forum | Wed Sep 12 13:11:50 EDT 2007 | nitro

Usually the bearings lock up. I keep one spare blower on hand and change it out when I have one go bad, then take the bad one apart and change the bearings. The bearings are about $4.00 per set and are pretty common. Not too hard to find. I am using

1.5. Width >= 4-5 Particle Diameters. Use the smallest opening to determine this. Using dimension of the smallest aperture width, you should be able to fit minimum of 4-5 solder balls side by side into the opening. For 0201 design, -400 mesh (type

People have made good comments. Additional points are: * Your bridging is probably being caused by one or more of the following: [1] printing too much paste, [2] smearing the paste during placement or subsequent handling, or [3] paste slump during t

surely, a big picture perspective is in order to keep from charging off, tilting at windmills and waning Quixotic. Just to tic ya off a bit more (come on now, smile), would those 2 boards in rework have just one defect each or are there multiple def

Handling PCB assy's

Electronics Forum | Fri Nov 01 18:57:32 EST 2002 | slthomas

I guess I just don't see how it would benefit us any. We rarely remove a board from the conveyor unless it's coming out of an oven. And why would you put bare boards on a tray? Why not into a destacker that feeds your line, so only the edges of a

Solder Paste
