Ok here I go again. I got rid of the last problem but now I am back to a different problem. When the machine sits and I press Reset, the screen reads Starting the Z-axis Homing the Programmable squeeges and just stays there and does nothing. So I E-s

If the uBGA has aperatures that are 0.25mm square, you need to use a laser cut foil no thicker than 3.75 mils to get an area ratio of 0.67, which is the minimum rule of thumb - that's too thin! Electroform would probably work up to 4.5 mils thick.

I would love to buy enough feeders, just for the common parts but unless I find somewhere cheap to buy them it can very expensive. We use our own internal part numbers with using smart feeding stations. Also we are going to try to leave all the comm

Steve, We're not so sure that we've had enough of your rant. You say "I think it is the only place that looked pre-SMT for issues that everyone else just assumes is SMT. Any complete solution to SMT changeover times will look at pre-SMT as much as

The ideas so far are good, but yet remember, we are running 4 different lines with "1" set of parts that are never removed from the feeders. We can not get purchasing to buy extra reels of the of the most used parts, and these parts travel from line

James, sounds like you need one of these: Feeder Arrangement Feeder arrangement problem concerns assigning components to the feeder slots Placement Sequence Placement sequencing (or insertion order) problem concerns determining the sequence in wh

All the opinion and recommendation given here is so useful, but there is not an optima solution for your specific problem. I recommend you to use some useful techniques of lean manufacturing like smed, kaizen , etc. it helps to get a solution for you

Hello all! I'm looking for examples of part data for BGAs created in the MCS-16 environment (V3.20). I've heard using vision number 1, and vision type 10 works, but comes up with a transmission error. As these vision numbers are for chip components,

Thanks for the replies, - solder paste used ? NC ? other ? Water soluble 63/37 paste - reflow in Air or N2 ? Infrared - temp ramp up before soack (�C/second) ? Will have to check. This profile has been used on numerous gold plated boards in our

Try sliding a standard plastic trash can liner in and out of the can a few times, then crumble up a few styrofoam (polystyrene) packing peanuts and dump the bits in. You'll be lucky if any of the bits even reach the bottom, unless it's an ESD safe re
