Hello Joe, PCB size 6" *6" is larger board. Resistors and LEDs are easy to do assembly. I think you can ask Beijing Glichn, from PCB stencil printer, SMT reflow oven and LED pick and place machine, they can give some suggestion. The investment is de

Hi, we do that for some of our assemblies(the only difference is that our cut in the PCB is bigger and the LED leads step on the paste right away). we place these manually. I assume that you can send them for tape and reel, and if they can find the r

There are reverse mount LED's specifically for this purpose. If you want to use standard ones I guess the best option would be to get someone to repackage them for you. http://www.avagotech.com/pages/en/leds/surface_mount_chipleds/reverse_mount_seri

Hello, The machine measures the part using the laser on the head after picking it up. It then passes or fails it by comparing it to the part size and tolerance for the pickup in the laser extents. You can see this in central controller under laser ex

Drives me nuts. When I first started here, the SMT operators would create oven recipes where the bottom heater zones were colder than the tops. Their logic was that then when running the second side, the parts wouldn't fall off because they would

I would check their data sheet for the particular product. Thats the range I have for Some Kester products I use... Are you seeing any slumping prior to pick-and-place? Is the bridge in the same place every time? How is your pick-and-place mounting

Although I don't know the answer to this I am sure one of these people could help you. They are all members of the SMTA with a great deal of BGA rework experience. Doug and Ed both teach rework classes for us. If you are interested in a BGA rework

I do not think there is a way to do all four at once, but I could be wrong. Questions: Are you using all four heads? Could you optimize nozzle config. to eliminate one or more heads? If all else fails, I guess have the operator come in 30 minutes

With any AOI machine, it will only be successful if your programmer is interested in getting it to run well. It is not rocket science, but if you want low false calls you need to invest time and energy into programming, especially if you have a high
