The Lizard Tongue is just a thin metal strip that, when actuated, slides over the BGA component and holds it down during transport. If you contact FUJI, they should be able to give you a part number, and install instructions..... maybe even the real

Hi, I have seen in the past programs on GSMs using a pushdown function so that the selected previously placed component can be pushed once again into the paste by one of the nozzles. I have tried using greater pressure on the placement but need that

TMC, Are you interested in this approach because you only have a flat belt conveyor and want to keep the components from being moved by the belt on the second pass? If so, you might try adding some stiffeners to the board edges to stand the board o

Print then dispense in the areas you need extra paste. Why can you not use a stencil which has areas etched away around component patterns to thin the stencil down....for example a 150 micron thick stencil etched to 120 or 100 microns in specific are

You definitely have to be careful with unsealed components and markings/labels. The best you can do is check with datasheets or find an extra assembly to test it out on first. You can also try slowing down your inline to more like 1-2 ft/min and se

I would suggest accepting components only in paper tape. I have had better luck with 0402s in punched paper over plastic embossed tape. You can also pick with oversized nozzles if your vision system does not give you trouble with seeing the nozzle.

Hi, One thing, getting back to the original topic, is you might want to panelize these boards as much as possible, as you don't have too many components, but you have some good volume. So the machine changeover time is going to be an issue. Althoug

Hi mike The solution is simple but two fold, first your process needs to be changed a bit, you need additional feeders to pre-stage the new P/N run and prestage the extra feeders for reload as certain higher volume components exhaust. The idea is t

The tact time is determined by the slowest machine in the line. In your case it is 4.5 min. This is the time from the board leaving the output conveyor sensor to the next board leaving the sensor. The first machine, which finishes the job in 3 min. h

Hello All, We assemble boards which are small in size. We use nests for support when screen printing the boards. The nest gives support along the edges of the board. However we are bringing in a new product which has components very close to one edg
