Hi WRIGHT, When you the standard, I assume you are talking about what kind of set-ups. If so, then RDR is right. Contact a supplier. Most sell the water and also units that can make D.I. water. It depends on your need and size of your cleaner.

There is no standard. Companies select a lower control limit based on the desired cleanliness. Guidelines to consider are: * With fresh resin beds, expect get 17.5 mohm-cm water into the final rinse and then it decreases from there. * Semiconducto

Chrys, Please, refer firsatly to J-STD-001 Appendix D. Now, consider: SIR testing will help define the reliability of your finished assembly - it will not tell you how clean it is. Which do you or your customer prefer? Present SIR testing de

In the following thread, http://www.smtnet.com/electronicsforum/view_message.cfm?message=9584& John Thorup touched on some applications where no-clean fluxes could be a bad idea. I'm looking for some more detailed info. (papers, references, texts

Hello, I am unaware of the standards that you are mentioning. If you have a soft copy pls. mail it to me. (ramanandkini@titan.co.in) If not, where on the web, these standards are available? All I know at present is that this is part of a Engineering

At my last place of employment, that was the big reason why nobody (especially the Design Engineers) bought into a no-clean process - interference with high-impedance circuits. One guy was so paranoid about flux residues remaining on the board, that

We have an electronic circuit with a miniature stepper motor, quartz crystal, Electrolytic capacitor,chip resistors and few smt LEDs. The PCB material is CEM1 with SMOBC and HALS finish. This circuit is assembled in a plastic casing and goes in to a

Ron - no clean = no water, de-ionized or otherwise. What you should determine is if no-clean is suitable for your end product (it likely is) Certain high frequency, high reliability, low level, environmental, or other conditions might suggest a wash

Mike -- Thanks for the information. It is very helpful. Is there any information available that shows what flux most companies are using? What fluxes are most companies that are producing Space, MIL-Spec, or other high-reliability assemblies usin
