Mike, I don't feel that I am putting too much emphasis on the EPA certification. If it wasn't for the EPA, I would still be using freon in my old degreaser and would not have needed to change chemistries 3 times in 5 years. Why fight the EPA if th

We have had Mydata for eight years and Siplace for six. We have found that the Siemens is much more accurate and faster than the Mydata (about four times quicker). Although the Mydata is more friendly regarding the software, if the upfront preparator

I've had good and bad experiences with OSP's. First of all, ask yourself, "Why use an OSP?" If you don't need it, don't use it. Solderability is dependent upon the number of thermal passes (the fewer, the better), the thickness of the coating, the

Nice to have you back on SMTnet. Some of the newer folk have missed-out on the solid contributions you�ve made to the Forum. The chicken wire cleaning basket was a classic!!! [It�s a shame that the folk at SMTnet can�t recover those files.] We bu

You should specify the level of res based on the effect of the res on the end-use of the product. J-STD-001 defines cleanliness requirements for ALL flux types, including water soluble and no-clean that you mention. 1 There is no equivalency betwee

Thanks, gentlemen. All points well taken, and some hit pretty close to home. Our pick-and-place programmer assures me that coplanarity isn't the issue because the machine won't (or can't) place parts beyond an acceptable criteria. It's an Amistar
