Hi, That's a good idea. I might head down the the 7-Eleven, and try it! I did not realize there is not too much to be gained by using refrigeration. We don't keep much paste in stock and buy it as we need it, so perhaps we should just keep it out r

Many trials conducted so far from single sided to Mixed technology dual wave with our LFB227/S 0.3Ag silver Lead free. Results are excellent, some say better than 63/37. One continueing problem though is the age old area of undercured resist and runn

I'd be interested to hear what the PWB vendors have to say about your comments. This is something I have questioned before, but I fail to see how this problem can be proved. Because of all the technicalites of the wave soldering process, it is someti

My suggestion is that there are alot of suppliers for this type product. Call a couple of distributors and have them send you samples. Make sure you know each manufacturer so that they don't duplicate. Review the performance and price of each one and

Russ is correct, The efficiency number, or machine operating ratio, is more relevant in a HVLM environment than a HMLV senario. I have found that in HVLM, a desirable number would be cetianly 80% plus. Low 90 is not unrealistic. One must consider

I have never used the Vitronics but have pretty extensive experience with the Electra as well as Ultra-Pak and econ-pak from electrovert. I ahve been impressed with these machines for their durability and ease of use. A laminar flow with the rotary
