I'm working on A DEK 265 Horizon and I need to convert it to right to left. I have changed the conveyor direction in software, however, the board stop position appears to be from 0 to 255 and I need it stop on the left hand side of the centre referen

Steve, I did this several years ago on a terribly designed board that left a lot of joints unsoldered after the wave. It works OK. This was a bog Irish board with nothing fancier than SOP packages. Glue was Amicon D125. Happy St. Patrick's Day everyo

The only way I know of waving the bottom side with SMT parts installed without epoxy would be to use a masking media, Kapton Tape, wave pallet that keeps those parts from being susceptible to gravity once the connections are reflowed. If there is ano

The temperature that will melt solder holding top side SMT components during wave soldering depends on the alloy of that solder. So, for example, you'd expect: * Near eutectic SnPb solder to melt around 215*C. * LF to melt around 240*C. It's common

J-STD-033B.1 Says "For cavity packages in which water may be entrpped, water clean processes after first reflow can be an additional source of moisture. This may present an additional risk, which should be evaluated." And it talks about derating if

I want to place smd's by hand from tape strips using a vacuum pump. What is the orientation of polarised smd components on reels/tapes? Is there a standard manufacturing orientation, or are there variations? I understand some manufactures have part

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

4. There is a possibility that your company have more than one vendor for a specific component (same partnumber for you but different mfg. part nr). Let say that it is a red led and this itself could be somewhat tricky to order: Red led is as most of

Polarity in tape and reel is usually always on the bottom left side. And that is correct for the trays, they have a corner taken out where the polarity goes. Hope that helps........

POCKET POSITION PROGRAMMING This procedure ensures the components are properly centered at the tape feeder pickup point (over spring stabilizer). NOTE: The feeder can be reset at any time by removing it from the feeder base and reinserting it. This
