I've never heard of a customer saying just 'we want decoupling caps'. Very interesting. In RF applications - frequencies 50MHz up into several GHz, the location of where they are put is just as important as what the value is. Decoupling caps are p

Hi Pete, What you are describing is something that will happen regardless of feeder type or machine type. When taking off a partial reel there is the potiential to lose components. It is minimised by careful handling. Yes I would agree that the Myda

CAL Here is another perspective. Ask what is included in the setup costs, ie. programming, stencils, setting up part number bins, bill of materials, changeover time on the line etc, etc. Then ask how much time and costs the CM is allowing for each

I have a CEM-1 PCB board with 35 microns copper. This is PCB is finished with SMOBC+HALS. We do solder SMT LEDs, but till date we do not have problems that you have listed. The LEDs are good & bright. It even passed high & low temp cycle tests (-40 t

Sam says, �The only question remaining to me is that why the failure happened after 48 hours instead of immediate failure after soldering.� Let�s recap: * Had good-looking solder flow. * Passed the initial electrical test. * Failed the later electri

Dean and fastek, Thanks for your input. Actually the MPM Accuflex is more accurate than the UP3000 and MPM will tell you that. The machine wasn't intentionally built that way but that is the way it turned out. Oh and Dean, what if the Piper Cub was

Start with a load cell (force sensor), you will need one that can handle the force range you will be placing. Someone please correct me on this if I'm wrong but I seem to recall that placement force runs in the range of a couple hundred grams. Chec

Ricardo makes some good points. My idea of a dream line is one that flexible to run as a high mix/low vol and low mix/high vol. I personally like Dek printers over MPM. The new printers from Mulara look interesting but they are a new company with a
