Several suggestions. Your hands may be tied but here goes. 1. Doctor your stencil so that pads are not shared etc and reduce the apertures more that what you would normally. This may stop one pad wetting into another etc. 2. The use of a Pb-free sol

This is similar to what i am looking. I have some ideas like Using spare nozzles for weekly cleaning to reduce downtime Using after windup solder paste on other lines to reduce solder scrap.

I am pretty sure, you are looking into the wrong spot. Your paste is too much, or your part has very inconsistent narrow leads(that includes wrong pad design as well.)

Hi KP, I�m wondering why you send those boards outhouse for the SMD part with a stencil. How do you know it fits their printer. We give the stencil data 1:1 to the subcon so that they can order the stencil to their needs with reduction and thicknes

There are 2 reasons for wanting to change to an enclosed print system: - Reduce solder paste usage. (We run a high volume application so any reduction in paste scrap is a big money saver to our company.) - Improved print quality. (Ours is a non-rew

Syringe is a good plan. You may need to buy some pnuematic guns to push ou the paste thuogh. Instead of melting the paste down, have someone reclaim for you. They pay you for it. Sorry Maint Managers - gave away your secret.

Have you thought about switching to either automatic paste dispensers or rhemoetric pumpheads in order to contain the paste and only dispense what is needed during your shift ? I am not sure what type of printers you have, but I know both of these o

Thanks for the reply Dave. :) No, we dont toss in 500g on the stencil. Have you heard of any method to convert the solder paste to solder bar, just in case someone have done that before? Thanks.

Yes, looks great - had a play at one of their roadshows. Could turn into an amazing product if they can scale it down enough. However, it's slow and costs more than a large house. More than a screen printer and a huge number of stencils.
