Expanding on a previous poster's comments ... Vapor Phase Soldering. A solder reflow technology that uses a heated solvent to melt the solder. Buried deep in the recesses of the SMTnet Library is �Terms & Definitions�. We started using vapor phas

My first reaction would be to run! FAST! Flex -- well, it... flexes... and isn't flat. While you assemble it, While you transport it, While it goes through the oven... SMT Connectors typically need to be held down during reflow. Fiducial types are

Hello Armin, If you are putting a matrix together to determine the best equipment set to use then a good path would be to start with your product and production expectations. Is this to be utilized strictly for typical SMT products? Are there any

Yes, providing the surface of the via is solderable. * If so, how much paste? => Vias come in various sizes. Boards vary in thickness. So, the amount of paste to fill a via varies. Roughly, you�ll need twice as much paste as the volume of the via

Your history is pretty good Dave although Multitroniks never had anything to do with Royonics. Multi was formerly Ragen who also made a light guided semi automatic PTH machine. They dabbled in SMT after changing their name to Multitroniks and takin

After a whole night's self review, I think we can term the slant/tilt as "floating 0805, yet end-terminals have acceptable solder joint formation". the width portion of the 0805 RES/CAP is (floating)elevated from the PCB pad, yet both (width) termin

We have a new assembly with bottom side components, and all the chip caps and resistors are 0603s. The dog boned shape of the caps necessitates a pretty big (and tall) dot to hold them still during placement, and when they get placed the dot squishe

No problem. Your buyer knows what she should order from the BOM. If she can�t order that, she submits an alternate part approval request to the customer early in the order cycle. If the supplier sends the wrong part: it�s rejected at incoming, get

Ask your compadres how you can control a process when it's output has already been completed? If you do second side assembly before you inspect the first side, you can't possibly apply real time corrective action. I know what I'm talking about in t

Hi Clark, Out of curiousity and in the name of learning new stuff, can you share with us how does your team, calculate the cost of inspection? Is inspection an additional chargable item in the quotation sheet? To quote your posting : "Just a side n
