Be careful when using a sticker, if it is too thick it can affect the print, you may get leakage which can cause the underside of the stencil to get dirty. Another option depending on the quantity is to segregate the boards so that you do not have t

All DEK 248 semi-auto printers have been built in China for quite some time (years). Its shipped to the UK from China. All DEK ELA models are now built in China (past 6 mos.?). Thats the fact Jack. All MPM models are built in Mass. Its the savings in

I thought this would be a good place to post to get input from the "trenches" as to what is going to be the next consumer fad? It seems like the market is in need of something new to instigate future consumption. I work for an electronic component

Russ, Be careful on how you determine your liquidous point. Sure 205-210�C is fine if your paste and the solderability protection on pads and component leads are near eutectic solder and things worked according to plan, but in real life it doesn't

Good points, John. Continuing to track on the voiding issue, why remove voids anyhow? * Voids are primarily process indicators. There is experimental evidence that voids retard crack propagation locally around the void on at least on a temporary bas

For me it was the 1.0mm nozzle, if we're talking mini-MELF here. Also, slowing the turret speed helps. Had mine at 30%. Results vary if placing on paste vs. glue. Paste is better. Still, the std. 1.0mm nozzle is where near as good as with the MELF no

Scott, We have 2 Amistar Placepro 5620's and 2 5720's. One with a TF-14. I've personally been working on these for the past 10 years or so. Have a pretty good grasp of the process, if placepro's are what you are using. Glad to see Amistar is

Knee of barrel and pad crack: Caused by thermal stress during soldering, because epoxy expands in the "z" 3X more than "x" or "y" which are restricted by the fiber. Related to: * Design of pads too large relative to hole diameter * Temperature at o
