It's all by feel and looks. Too many variables to tell you exact number of times. Most profile boards are set up to perform initial profile and then repeatability at a set period after that. So changing boards will alter the t-couple and skew your

I am in the R&D department at KIC. We have been making thermal profiling equipment for 20+ years. A standard circuit board is made from FR4 fiberglass. A typical solder reflow profile, whether leaded or unleaded, takes the board above the "glass t

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.

Any one have experience of MyData paste jet printing? I don't ave chance to take a look at Apex but it can reduce the paste, no stencil required and paste volume control by programming.

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.

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.

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

We are exploring ways to reduce the waste of solder paste. Here are some of the ideas I have in mind: 1) To use paste supplied in Syringe instead of jar. Paste that are opened more than 8 hours will normally be discarded, so we are looking for ways

We buy our paste in Semco cartridges. You don't need a pneumatic gun to administer the paste to the stencil, just use a caulk gun which you should be able to purchase at your local hardware store. The cheap ones are about $2 (US). We have green
