Metal Analysis
Analysis Options
The Kester Solder Analysis Program is designed to provide the control required
for a quality soldering process. Sample-mailer envelopes include documentation
and instructions for sending the solder sample to the Kester Analytical
Laboratories. Selection of the analysis option which best monitors the
composition will assure quality control of the solder.
We will no longer be offering Options A and D
Tin | Copper | Antimony | Gold
Cadmium | Aluminum | Zinc | Iron
Arsenic | Bismuth | Silver | Nickel |
For very critical soldering applications there may be a
requirement to monitor other impurities in the solder. This option choice
includes cadmium, aluminum, zinc, iron, arsenic, bismuth, silver and nickel. |
Control Reliability
The solder in an automatic soldering machine becomes contaminated with other
metals dissolved during the process. These impurities can affect the surface
tension and wetting ability of the solder, resulting in defects such as
icicling, bridging, pin-holing, webbing, dull connections, and excess solder
grittiness. A program of scheduled analyses of the solder can increase
reliability and reduce rework of soldered assemblies.
Analysis Report
Each analytical report is reviewed by the Analytical Laboratory to determine
the quality of the solder. The analytical report is mailed with 48 hours after
receipt of the solder sample. A report faxing expedite service is available for
an additional $5.00 US. Recommendations are made based on the contamination
levels shown in the analysis so a decision can be made to continue using the
solder or to replace it. The analysis report is in compliance with MIL-STD-454,
WS-6536, DOD-2000 and IPC-S-815.
Quantity Pricing
For high production soldering lines and /or when several automated machines are
being controlled, a determination of the number of analyses required can reduce
cost. Please contact Kester's Customer Service
Center for current pricing and quantity discounts.
How to Use This Service
An initial analytical control can be established by sending a solder sample for
analysis once a month for 3 - 6 months. The usable life of the solder and the
frequency of required analyses can then be determined. The sampler-mailer
envelopes include the necessary documentation and instructions, are registered
to the purchaser and addressed to the Kester Analytical Laboratory to assure
prompt, direct response.
