There is distilled water and distilled water. It depends on the distallation process used. Using distilled water is fine, as long as it meets your standard. So, if you buy distilled water, get a written certification that conductivity is less than 1

Hi Colin, Yes there are such machines available, new prices start at around $10K. You can also have a taping house sort out your current stock & buy in taped for next time which would be far cheaper (However pack quantities will change a lot). If

JEDEC defines packaging, matrix trays, tape and reel, and like whatnot. You need to be searching ANSI and IPC. Find these documents: * ANSI/J-STD-020, Moisture/Reflow Sensitivity Classification for Plastic Integrated Circuit Surface Mount Devices *

Yes, appropriate storage & component handling proceedures should be followed depending on the MSL (Moisture Sensitivity Level) class of the component. Some component suppliers are now marking the MSL class on the label, along with PBT (Peak Body
