How thick is this pallet? 6mm, 8mm, 10mm? I would look at: Make sure you're pot height is correct (lead clearance). If you are burrying the pallet in the fountain, your going to "push" a large volume away. The solder "push" should not plow over t

Jay, Yes, we did assigned new part numbers for our lead free components. Our concern was how do we know that this component is lead free. New part numbers was our only way. It made the component engineers cry, but offer them a box of Krispy Kreames

We approached it the same way we select SnPb pastes. We started by doing coupon level tests to sort out the obvious "bad" pastes: SIR, wetting, solder balling, print quality, etc. That cut the field in half. From there we started to do assembly l

Hi, I take it you are refering to intrusive reflow? It came around as more components became available in surface mount packages leaving mainly connectors left over for a separate insertion operation & wave/selective/hand solder. Manufacturers imp

I am looking for some feedback on the Seica Firefly Laser Soldering System. We saw a demo and were somewhat impressed but would like to hear from anyone that has any practical experience using one. Specifically, we noticed that you have to select t

There are many users of SN100C in reflow. SN100C was originally introduced as a wave solder alloy which offered cost savings over SAC, no solder pot erosion, and high fluidity. Since it is eutectic, no plastic range, the joints have a smooth, shiny

Thanks for the acvice, Dave and John. Like I stated above, I didn't feel comfortable with changing wave parameters since I knew that we'd be compromising our wave quality. I'll try the peelable mask thing, reprofile, and let you guys know what i fo

Just a thought.... Some Fluxes require temperatures upto 260F (127C). Are you using water based flux or solvent (alcohol). I have noticed that many wave machines are NOT capable of preheating adequately when using water based materials. This can

Dave: I haven't located something to support your contention, yet, and I'm not going to comment on the factors that drive reliability beyond component selection, because I know that you've got some sweaty-palmed sales type wringing his hands waiting

Rob, We are also using intrusive reflow to simultaneously process SMT and Thru-hole components. Our arrangement goes as follows: - Screen print solder paste to the single sided PCB using 0.008" laser cut stencil. - Apply adhesive dots to selected
