What works in Alaska will probably not work as well in Florida. We have solder paste vendors give us direction with their specific paste, but we also impart our required process parameters on their paste. For instance, here in Alabama in the summ

Kinda what I thought, Ken, what would the parameters be relating to sphericity, flux, etc... We use type 3 63/37 usually watersoluble but for this I think I'm gonna have to use no-clean paste. When you say it can be done, what exactly does that

We are trying to deploy an Ionograph cleanliness tester and wanted to know what others are using as a standard test sample. My desire is to run the test on a weekly basis using the same medium complexity assembly. We plan to use the testing as a pr

We currently use a KIC 2000 system to profile on our oven and create our recipes. I had a customer in today reviewing our profiles, and he had concerns that we were exceeding 4 deg. c/sec. on our profiles. The process window parameters that we use

If there is an empty pocket at the pick up position, because a component "fell off" then the pick and place machine will attempt to pick up more components from the same feeder an "x" amount of times, depending on your component parameters, then it w

Wire bonds don't stick when bonded * Check pull and shear strength. * Depending on point of failure, review parameters. * Listen during bonding, if there is a high pitch buzz, there is vibration in the system somewhere, "seek and destroy". * Get the

We have Kester 256 no-clean spec'd as an alternate paste. I bring some 256 in occasionally to make sure it still works as a backup. The last batch I brought in was bridging like crazy. Scraped it off the stencil, put our regular Alpha back down an

Sure you can use SPC charting on the wave setup parameters to warn of impending problems. Examples of useful points of analysis are: * Dwell * Temperature * Pot analysis Certainly there's a range of other process controls that could be monitored.
