Hi Dave, To close-loop or not to close-loop, that is the question� I can not speak for all machines, but in our case, close-loop systems are actually less costly to operate than open-loop systems (we make both). First, determine the volume of wate

Additionally, increases in temperature can increase the water's rate of reaction with the flux. Sometimes, only a 5 degree change can make the cleaning difference. If the flux inconsistently presents itself, then the likely cause is something in

The issue is not the cleanliness of your in-bound water. The issue is the cleanliness of the board your customer receives. Look at J-STD-001C, Para 8, "Cleanliness Requirements". The end product cleanliness is the end result of your: * In-bound

Mario: Your ask a very broad question and give no background information. Generally, the amount and type of residues present on a printed circuit board at the very beginning of a SMT line depends on the exposure of the board up to that point. For

In all likelihood, you may not be leaving flux on the board rather you may be leaving saponifier on the board. Improper rinsing is a leading cause of cleaning related board failures. The problem with some inline cleaning systems (especially old o

| Scott, | I am not really in a position to answer this as fully as I would like because most military work with which I am familiar is subject to some degree of secrecy most especially on the internet. At least we have signed up to such restrictions

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
