Truthfully, there are pro's and con's for both technologies. (put cost of ownership aside for one moment) Nitrogen won't dry humidified components as rapidly as a desiccant dry box. I'm talking about a self regenerating dry box that uses molecular s

Yes, electronics manufacturing is a volume producer of cardboard waste. If the components are ESD-critical, cardboard and most plastics are not ESD safe. Static charges can be generated on these materials during handling by the friction of dissimila

I have two basic questions: 1. We have a number of small convection ovens and want to modify some of these for baking out parts when needed. We have tried pumping nitrogen into these but I still run between 35 and 50 RH. Has anyone tried converting a

We use dry boxes manufactured by DMS Clean Room Products in Lawrence, MA. The phone number on the tag is (508)683-2325, but I think their area code changed to either 978 or 781 recently. We flow dry nitrogen through the box in order to ensure that

Almost all boards are hydroscopic. In this, the epoxy holding the board together absorbs moisture. Almost all components are hydroscopic. In this, the epoxy encapsulating the component together absorbs moisture. So, as you heat the board / compon

If we understand correctly, your SMT solder connections remelt when passing through the wave solder machine and your QA-people don't like it when that happens. It's nice not to remelt this solder, but as long as the board meets your acceptance stand
