| Is their an IPC standard for the water that is being used in the water wash. I have been looking and at this time have not found any thing. Try these: IPC-AC-62 Post Solder Aqueous Cleaning Handbook

First, it is very difficult to properly clean under devices like yours. Second, your ultrasonic cleaner should not be damaging or loosening encapsulated components. It sounds like: * Cleaner is not of the proper type for cleaning electrics. * Cle

We have an up coming job that has conductive ink deposits on the solder side of the PCB for contact switches and a zebra strip that connects to an LCD display. My question is... Do these need to be masked to protect them from the wave solder process

It's not acceptable to us. More importantly, you need to determine if it's acceptable to your customer. Recognize that your little IPA scrub does NOT remove the OA flux residues from the board. It mearly spreads them out across the board and under c

I need some feedback on aqueous cleaners. We currently use a Unit Design batch cleaner. We will be looking to upgrade our board washing process and batch sizes in the near future. I am looking for user info. on the advantages/disadvantages to using b

Batch vs. In-Line for straight aqueous cleaning applications tends to be all about production. You'll have to see what cycle times you get from the various batch systems out there vs. the in-lines. In-Lines come in various sizes. Some of the leading

Hello. We have a low profile LCC on a board. The clearance is ~ 2mils after reflow. Cleaning away residual flux with an ultrasonic 50C water cleaner caused some LCC and 0201 components to loosen. Should we stay away from the ultrasonic cleaner?

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

There is no the industry standard specification for resisitivity monitoring at aqueous cleaning. Beyond those posted here earlier by Mikie, guidelines can be found in the fine SMTnet Archives, for instance: (http://www.smtnet.com/Forums/Index.cfm?CF
