Mike, Is that greater than 80% yeilds, or less than? Here are the answers to your questions: Is you placement guranteed good? YES What x-ray have you used? Nicolet Are your fab.'s known good? YES Could you de-solder Samsung and replace with ano

Absolutely Mike Lets take that one step further and say that almost anything that you use to clean up with will from then on be considered hazardous waste. Wiping rags/pads, the previously mentioned vacuum bags/filters, the piece of cardboard that yo

Dear Dave and Mike, I do not normally respond to threads of the forum. However, I do enjoy reading other's comments. There is a lot of valuable information provided by both suppliers and users. You seem to be making light of Bill Schreiber's com

Hi Kerry, I do not wish to turn this subject in to a debate, but consider this� If every technical question posted resulted in a commercial reply (company name, model number, phone number, price, features and benefits, etc), then there would be lit

Hi Mike, The Smart Sonic 440-R SMT detergent is certified safe and effective by the EPA (I downloaded the documents from their web site). Is this true of the other chemistries that you referenced? If so, where can I find the documentation? If not,

I would recommend pH neutral chemistries, particularly if a semi-automatic machine is to be used. There are many chemistries available. A partial list of chemistries that I have tested, and that are compatible with a variety of cleaning equipment i

As the manufacturer of the Zero-Ion, I must correct one statement made by Dave F. According to the EMPF report sited in Dave�s response, �Static� based systems actually are more susceptible to carbon Dioxide adsorption than �Dynamic� based systems.

Your question may be answered in two parts. First, if you are using a water soluble (OA) paste, then water is an excellent �solvent�. Water, in one way or another, is used to clean all fluxes and pastes from PCB�s. In some cases, a chemical is add

Justin, I would be currious as to your customers application, and if the temperature delta and rate are great enough to cause solder joint failures as a function of mismatched Tce then you may want to consider that even if you are able to identify

Mike, Thanks for the reply. It's not really a matter of slope. It is the long term thermomechanical fatigue that the solder joint undergoes as a result of repeated severe temperature swings, while the product is in use. Non-leaded parts are suscep
