Does anyone know of a SMT reflow modeling simulation that I could use as a baseline for reflow profiling? I'm looking for a quick means of setting up oven profiles for various oven sizes based upon board density (grams/sq in) and conveyor speed.

All, Thanks for your quick response. However, my primary concern is not the question of solderability advantages of nitrogen versus air. With all things (zone temps, track speeds, flow rates, etc.) being equal, what would be the profile differences o

Mark - The Waverider is a great tool. It will let you know what's going on with the machine itself - contact time in the wave, parallelism of the wave, temp, and a relative idea of whats happening in the preheat section, and conveyor speed. We hav

1. Check printing accuracy. 2. Check placement accuracy. 3. Your components should be kept in a good environment to prevent oxidation of terminations. 4. Pads pattern should be designed according to standards. If 1.2. are okay, you should suspect 3

Hi, You are right, but if you don't have very fast ship shooter then i think that dispenser is better. I have experience on both variation. If you have a line dispenser then speed is quite good. Most often it is sufficient. And unfortunate often qual

Right!!!! We have built product with via holes only 0.010" off the edge of the routed edge or even routed them in half, which usually adds cost and shorts to the chassis. Most high speed routing has a tolerance of +- 0.005". It's common for UL fi

We recently installed a new Servo-Amp which controls the X-Y table on our CP6 machine. Eversince, we are experiencing a Cycle alarm X-reach on the machine. We tried to greased the table a little bit more but the only thing that seems to work is to sl

Have you thought about stencils for glue? We stencil all glue boards quite succesfully. No CAD no clogged nozzles, much faster speed aperture designs are fun to work with. Just a thought for an alternative. All the companies mentioned also will advis

All, Can anyone point me in the right direction for (sources of info) various ways to quickly cure RTV or atleast speed up the process. Our requirements are to use Dow Corning 3145 hi-temp RTV. I have tried contacting the manufacturer but am losing
