J-STD-001C just requires that the area not be so dirty as to contaminate your product, tools, workspace, etc. If you start counting particles, you're into cleanroom territory. Do a search on ISO 14644-1 for specifics. Actually Wikipedia does a ni

IPC-J-STD-001E in regards to Ionic Cleanliness standards states less than 1.56 µg/cm² of total NaCL. Assuming a typical electronic process which involves smt, wave, and post-hand soldering and uses NO-Clean flux throughout all process, is it typi

There is no standard for deionzed water when used to clean boards. As you state, J-STD-001 defines a cleanliness requirement and a method for determining cleanliness. How you go about meeting that requirement is your decision, as it should be. Fresh

All of the discussion of "environmental controls" are a matter of degree, dependent on the requirements of the product that you manufacture. For example: shops assembling under-the-hood products have different requirements than shops making garage d

You should specify the level of res based on the effect of the res on the end-use of the product. J-STD-001 defines cleanliness requirements for ALL flux types, including water soluble and no-clean that you mention. 1 There is no equivalency betwee
