If you have another container of flux that is a different batch try that. Dont forget to clear lines of old flux. check spray pattern width. The activators needed may be dead in flux.Since it is sudden my question would be what just changed?

Hi, I have a customer who's electronic assemblies produce RF. He is insisting upon aqueuos cleaning. We switched to a no clean solder years ago and no longer have an aqueous system. Is aqueous cleaning necessary to eliminate 'cross talk' of the s

Hi, Walter, Why don't you try no-clean flux? We ever met the same condition, later, we changed to no-clean flux solved the problem.

Hello Ramon, This is a very common problem that usually can be overcome. Can you tell me the flux type you are using (manufacturer, and flux number)? Has your board vendor, or type of PCB's changed (are they entec coated - bare copper)? What is t

Thanks for your advise Normally, We do not add any liquid flux (clean or No-clean) during touch up process but this case is an error. Lonco 23F is Nc flux. but our board is clean. However, there are 6 boards that found the white residue and our

Hi esoderberg - I was wondering if you had tried altering your soldering profile to try and fully solublize the no clean flux residues and elimate your cleaning dilemma? You can check out my company's website if you want some free reference material

Hello Dr. Lee, Will no-clean fluxes be more of a challenge to develop?

In theory, no clean flux residues are electrically benign...period. Here's a good test. Subject the board to some moisture/humidity, and have your circuit designer ohm-out any areas that may be affected by conductive material. Option B: Have a la

I will convinced to change to the no clean process by environmental safe even though clean process is water soluble but it still produce the waste. Also, the BGA is not recommend to clean, if the flux is not completed removed from the board and elec

Just curious� Why only localized cleaning? Why not clean the entire board? Localized cleaning by nature is labor intensive. Mike Konrad Aqueous Technologies (909) 944-7771 ext 29 www.aqueoustech.com konrad@aqueoustech.com
