If you have concerns, you can look at the datasheet for each component or contact one of their application or materials engineers and find out what the components are rated for...process-wise. IE, how long can I be in the oven with this part, at what

These ovens maintain good profiling as long as you stay on top of maintenance. I had 4 150's and 1 125. The biggest headache is keep the plenums cleaned (very messy). Also the blower motors have been replaced a few times on them as well. If I were yo

Maybe this piece of information will help. In China (just returned from visit) there are many factories that are using a dual temperature process using SAC305 or Sn100C and 42/58. Apparently this allows them to run their through hole parts through re

First, we have never repackage devices, as you propose. Our schedule has us standing at Receiving like panting dogs waiting for the material required to jump the job, much less giving up the time and money to have parts repackaged. Second, fabricat

I am having a problem with some joints on a 100 pin pqfp and few different soics on one particular board. When viewed a 8x with a "Mantis" inspection scope the joints look as though they wetted to the ic leg but when probed the leg will pop loose.

Charlie: People cure glue using their paste reflow profile all the time. And most of them are happy. Personally, I�m with Dean and Travis. It�s possible to as you suggest, it�s appealing not to mess with your oven profile, but it just doesn�t s
