Hi This is a good one. Let me take a stab at it. First remind me, why is this air coming in carrying a charge. I think I remember yet it is always fun. Also hopefully it isn't carrying any compressor oils. There are some companys that make other t

Hi Let me just give a little and someone else might chip in with fast and ready details. I don't know what your product or service is, so I am not sure how direct to the FDA you need to be for your shop. If you work for someone they should handle t

Hi I see David F already gave a good answer. The basic advantage, if you can afford it, is a more stable PCB during the soldering process. Higher Tg enables this. Also some materials serve to match CTEs (coefficient of thermal expansion) a bit bett

I just can't accept that what I want to do hasn't been thought of before. It's to basic a concept for there not to be an existing product that can at least do something reasonably close. There are too many manufacturing environments and locations f

Hi Excellent David F. I don't know about the company CAL is working for but I will tell you that sometimes companies hire a weak talent and convince them that they have a high sales potential. They offer a big commission yet a low salary in the 30K
