Metallic Resources offers a complete range of value-added solder analytical services to printed circuit board assembly and fabrication businesses at no charge. Each and every order that is shipped from the manufacturing plant includes a lot number, a “Certificate of Conformance”, and a “Certificate of Analysis”. The Certificate of Conformance details the lot number and all relevant specifications either met or exceeded. The Certificate of Analysis shows the exact percentages of component metals.
Customers are provided informational cards and mailers to return
solder samples to Metallic Resources. The samples are then analyzed
spectrographically to determine concentrations for the following
elements: arsenic, antimony, gold, iron, nickel, bismuth, aluminum,
copper, silver, zinc, cadmium, indium, sulfur, and phosphorus in
addition to tin and lead. Metallic Resources provides solder pot
analyses when requested at no charge with results faxed to the customer
within 24 hours of receipt of the sample.
Metallic Resources’ analytical services are most often used to assure
the solder pot has not become contaminated with other metals.
Periodically testing the solder will insure the correct balance of
tin/lead is being maintained to assure superior solder performance and
that the solder bath has not become contaminated with deleterious
Printed circuit board fabricators and assemblers are assured of high
quality solder in the pot, constantly kept within specification ranges.
Rates of rejection are reduced, thereby creating a more cost-effective
and profitable manufacturing process. Many other solder manufacturers
provide analytical services, but often charge the customer and take at
least a week to provide analytical results; in the meantime, if the pot
is contaminated, a week’s worth of production using contaminated solder
