Hi Dave, It may be. DI water alone will not build up residue. It can attack the finish of electro-polished (mirrored) stainless steel though. I have seen a white / chalky buildup on poly inline cleaners, usually isolated in the wash section. The

Surfactant. A synthetic detergent made from petrochemicals that lowers the surface tension of water and allows better cleaning in small spaces. Do you have a cleaning issue that requires you to use a surfactant? If so, be aware that you must clean

Without being clear on whether you're talking about: * Standard air knives at the back-end of your in-line cleaner ... OR * Hand held or similar nozzle. Standard air knives: This causes no problem with ESD because the relative humidity is so high t

WA Engineer, If you are able to change over to OA instead of RMA, you can clean effectively with DI water. (I know that some Military contracts specify RMA) Most systems are designed to filter the waste water of ionized contaminants before dumping t

If you can change to SN100C do it. The nickel prevents the high tin content from eating away at the metals on the tips. Similar to what the Lead did in 63/37 alloys. This Koki crap is just that, crap. 99% tin??? Thats what is causing the problem peop

Here in the Great White North, the best way to check our CM's compliance with the ESD 20.20 is to take a couple months worth of data during heating season and graph it against the outside temp swings. You can easily see how the HVAC system keeps up,

J-STD-001 doesn't necessarily require additional controls under conditions of low humidity, only that you verify the effectiveness of what you have in place. ESD S20.20 [1999] only says that relative humidity above 30% is "desirable". ESD S20.20 [200

How do you get your X-ray machine checked out? We had the tube replaced and they checked it then otherwise we would have the same guy we had in last year to check it out. But in any case we have a radiaton survey done at least once a year. I assume

A simple question with very complex answers... But to simplify, you could start at this. Water soluble fluxes are cleaned using (typically) de-ionized water, using a spray wash method. Sometimes a saponifier is added to the water to help it get

We have a printer with Hawkeye 1700. The PCB side sometimes returns a distorted picture. It happens erratically, can be at startup or after a while, sometimes the machine works full day without problems. The only way to restore operation is disconnec
