Now that I've seen the pics... Soldering could work just fine. If you are going for large production then you could get copper discs cut and mounted in tape carrier ($$). This would make it very easy for automated equipment to assemble. Mounting a

Dear Sean Contrary to believe MOST formulators of No Clean fluxes or No Residue fluxes use organic acides that are in fact weak and benign. IF the residue was left on the board and you had a condensing atmosphere then you may see some issue with fal

Hi Patrick, thanks for the response. I might add some more information - we succesfully soldered some boards with the same settings of belt speed, pre-heat temp. etc. This batch of boards differs from the previous in a way that they are 4-layer. May

Im not sure that 0.004% is that critical in a solder alloy. If people are using our alloy and the Nickel increases we would most probably suggest running a dopant alloy without Nickel to bring the levels back down, it is very rare to require dumping

I'd like to correct a few of the points made above. Orbotech have sold their Assembly business to Orpro Vision GmbH, we are based in Germany, where we developed the Vantage S22, Symbion S36 and their predecessors the VT / Trion series. Both Develop

Hi. We are planning a production run of a board that utilises the SEMTECH SLP2710P8 8-pin device (2.7 x 1.0 x 0.58mm). The part orientation on the board necessitates that the squeegee print direction approaches the stencil apertures on the long side

The Z-axis Drive card on our MPM UP2000 HiE fried. We replaced it with a new card, setting all the jumpers to match the old card. After that we had to recalibrate the Z-axis and the snugger height but the problem is that the camera is now too close t

Hi, You don't need X-ray and all that crap. I would get an old MYDATA TP9 or something like that, and a manual stencil printer and a batch oven or a small inline oven. Should do the trick and be very low cost. Should be simple to use as well. Tha
