Hello AJ, The previous answers are correct; Sn has seen a spike in price ever since RoHs was implemented. Furthermore, the other alloys that have been used to replace Pb (because of RoHs) have also seen an increase in price. Sadly these material rep

What's the resistance value level of lead-free joint?Could anyone share me with the information? Thanks in advance Jed

We have carriers that we use in wave flow solderers that are machined specifically for each board out of ESD composite. I was wondering if anyone knows about lead contamination of this material and the cleaning of composite? I know that it is a p

Minimal cost and low melting point??? Have you bought Indium or Bismuth based alloys lately? Tin/Silver, Tin silver coper-X you name it....there are trade-offs (cost / performance). Not all are exactly published or are suitable for all appliations

mostly we buy our solder paste in countries with high labor cost thus making it expensive. Check out China. Won't you believe they sell LF paste at a fraction of a cost of a well known brand.

Well known American,Japanese and European brand cost between US$75 TO US$150 PER KILO. China made cost at US$50 to US$75 per kilo.Free shipping and in stock.

Resistance: Tables of wire gauge often provide a resistance measure of some kind for each gauge. That way we can estimate the resistance of any length of wire we might be interested in. Calculating trace resistance is only slightly more complicated.

The lead free debates are getting more and more interesting Didn't know that low labor cost was also lowering melting temps of LF alloys
