We understand the problem of trying to coat over RTV. We have seen the same problem with acrylic and urethane coatings not wanting to stick to RTV. Some acrylics seem to be worse than urethane. Since this is a new product, may be you could pot your

Comments are: * General purpose RTV (RTV-108) releases an acetic acid (vinegar) during cure and corrodes copper, brass and sensitive metals. It is therefore NOT for use in delicate electrical or electronic applications. However, there is an electrica

We manufacture opto-electronics, small ccd cameras for pipeline inspection. I was wondering if anyone knew of a standard value for the recommended humidity of an assembly environment for optos in particular or for general electronic assembly. We had

Our front panels (where the controls show) for our assembled amplifiers are anodized and we make sure that it is free from oils or other stains prior packing the whole assembled unit. We just use damp cloth in cleaning and sometimes flux remover for

Can I dip the populated board in flux and achieve good results? Also how easy is it to clean the flux off the board afterwards if it is waterbased? Do you simply brush the board with a damp brush or spray some remover on the board? I also have this q

We have used 2 lubricants in the past. The first was Isopropal alcohol, this has issues with regard to H&S but can be quite effective. Most of our product at the time we encountered this problem were washed in a semi aqueous system before shipping. A

Hi, it is not necessary to store MSDs in nitrogen to stop them absorbing moisture, just a dry environment. Nitrogen storage is good for storing devices for many years as it reduces the oxidation of the solderable surfaces. Best option for storing MSD

the cause could be moisture in your pcbs. To check it...pass some bare pcbs through your reflow oven (this is a simple way of drying them out a bit), then paste and place and reflow as normal....if solder beads disappear then the pcbs have too much m

Victor, I am wondering why you are keeping the RH as low as 32% ?? The lower you go, the higher your ESD problems will be. The voltages generated at about 40% are roughly halved when you reach 55% I believe that an acceptable level is about 55%-65

800 degrees? Ouch! I find that every company that I do training for has at least one person that likes to go through one tip a day. The solution is tip tinning. Tell your operators to wipe the tip on a damp sponge often. Do not buy your sponges
