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

[clipped] Chemistry of Hard and Soft Water From Anne Marie Helmenstine, Ph.D., Your Guide to Chemistry. Water Works I'm sure you've heard the terms 'hard water' and 'soft water', but do you know what they mean? Is one type of water somehow better th

The only time I ever saw problems with stenciling glue was when one know it all operator was using IPA to clean the stencil. He didn't seem to be able to understand that alcohol was a curing agent for that particular glue. But other than that, as l

A lot of our dewetting is happening on plastic body components, such as ICs. When they are manufactured, the molding process requires a mold release to make the part release after molding. Usually, the release agent is silicon based, but you can't

Thank you for all your inputs, I was thought not to use alcohol on stencil (Since it is a drying agent and reaction to Cu solidification), Am I wrong? Regards,Aybars

The presence of agitation at an air / solution interface and a foaming agent causes foaming. Most water soluable fluxes contain surficants. Surficants are foaming agents. First, it's likely this foaming is caused by poor control of the temperature o

Here's a link to an article regarding foam mitigation techniques. It my be helpful. There are many causes of foam. Water alone does not foam. Flux, solubilized in to the water can produce foam. Defluxing additives contain defaming agents which should

Hi All. I have one of these, which was bought secondhand and has never been commissioned. Does anyone out there know of a UK agent who services these, or can help with any advice regarding spares, operation characteristics etc? Thanks in advance.

I have always understood that on boards (or circuits) operating over 900 MHz, No Clean fluxes are to be avoided. Apparently the residues left behind, while non-conductive and non-corrosive, will change impedence of the circuit. It may be a possibil
