If you are talking about reflowing surfacemount on the solder side of the assembly, that is accomplished by gluing the smt components to the bottom of the board. I recomend that you use a chip wave in conjuction with the normal wave to get the best r

We have Siemens S-20 machine whose other gantry occasionally missmounts all its components in Y-direction(approx. 1/2 mm ). Most of the missmounts happens when there is a lot of 0603 or 0805s (B-side glue boards). Gantry picks up the components OK bu

hi. guys Have you out there ever seen the crack by means of humidity after reflow solering. We cannot analyze the cause of the tsop crack. The shape of crack seem to be hitted by sharp stuff. but there is no scar around crack . TSOP shaped long rec

The Brady PAM 5000 may work for you as well. I think they have a web site. This machine is smema compatible. It's automatically places barcode labels onto pcb's within an 18"x22" area with .020" accuracy. The labels can be placed at 0 or 90 deg onto

Brian & Nancy, Yes, our goal is to have the option of displaying the whole thread in one page while still leaving the current option available. Displaying all of the messages in a thread really doesn't work well with the old messages because they c

As a stencil vendor to some assembly houses and small in-house assembly shops, both without CAD people rushing to put the paste layers (if they even generate one) into stencil friendly format, the silk screen is the only communication tool we have to

| We have three buckets filled with leftover solder paste from our screen printing process. Kester has informed me that they no longer take paste, but only dross and pot dumpings. Does anyone know if there's someplace I can recycle this, or am I go

I have a board, 4 spacers needed to be soldered on the board first with the normal 62Sn37Pb alloy. Then, capacitors are manually soldered on the boards. The density of the board is quite high. If we wave soldered capacitors first, there will be no p
