does anyone know about JUKI electric feeder and machinery feeder difference

My company uses both Juki electric and mechanical feeders. Yes, electric feeders are much more efficient than mechanical as far as pick speed and general feed speed. However, if a reel runs out, it usually takes our operators under a minute to change

now days, I face a problem for JUKI electric feeder and machinery feeder. i do not know about any of electric feeder. until now, we all use machinery feeder for CF081ER 7' real holder and 15' real holder,CF03HPR ,FF12FS,FF16FS,AF24FS-OP. but this tim

We allow no silicone in our shop, because they ruin solderability.

Especially VCM - volatile condensable materials. Strictly verboten around optics.

Hose and/or Dave, Please elaborate of how the silicone can affect soldering. Material itself or fumes?

NASA is concerned about outgassing in high-vacuum environments. They select materials to minimize outgassing. http://outgassing.nasa.gov/og_desc.html

We use nothing but silicones and have for at least the last 7 years. We don't have relays, but we do have motors. No issues with soldering, but our lines are constructed such that the last solder operation is a good distance from the coating or pot

Material, fumes, cured or uncured, all are suspect. Silicone gets on an operator's hands, that operator handles components ( even a day or more later ) silicone is transferred to the solder connections = contamination. Process and workcell control

We are developing a new product that requires conformal coating on the motor controller. We selected a silicone based conformal coat due to its ease of use. There has been disagreement among engineers as to its impact on the motor. We have contact

IMHO I would avoid sprayed silicones like the plague. They can travel around your facility and cause solder wetting issues that you will never know the root cause for. Also found this e-drive article on using silicones around motors and relays. Loo
