Is anyone out there having problems with noise in analog circuits caused by the residue that no-clean solder paste leaves after reflow? If so do you have any suggestions on how to eliminate the problem??

Hi Chuck We make precision analog and hybrib audio processing equipment for the radio and TV broadcast industry. We have not experienced any problems relating to no-clean reflow since the introduction of the process several years ago. It is known t

We assemble for a customer that is having an inconsistent low level analog interference we believe with the no clean flux residue from Alphas OM5100 solder paste. We are considering testing Amtechs 4300 water washable no clean paste. We will test bot

This is sort of interesting. We had a clock problem with Alpha OM-338 lead free paste. The flux residue was causing a clock problem and the clock was only a few KHz. We went back ot OM-5100 lead paste and the problem never occurred again. Chris

Even though this is a "no clean" flux, are you (or the customer) cleaning the boards? If this is truly a low signal level device, there is no way you will get away without cleaning the flux residue. I do a lot of low-level hardware, and we have to

Hi, you can do it using Cadence and it's subprograms or you could find someone with ownmade convertor(there are a lot of people who work om the problem last years.I know 2-3 and if I find some of them I'll give you their coordinates.

Hi Benny, Move on over to some other forum like EDN or EETimes and piles more to post your question. Your luck will be vastly improved. This forum is not the best for electronic design issues like you are asking. YiENG, MA/NY DDave

Hi, I am designing a PCB which consist of Instrumentation Amplifiers, Programmable Gain Amplifiers, Switched Cap Filters, FPGAs & many ADCs. Involves low level Analog signals. How to patrician the layout so Analog & Digital signals do not interfere.
