Sn-Pb Ceramic MLCC Products
Johanson Dielectrics’ tin-lead plated products are offered
for high reliability, aerospace, and other applications
where tin whiskering is a concern. The plating is tin lead
over nickel barrier with 5% minimum lead content. The
lead content of the plating in every manufacturing lot is
verified using XRF method, and this data is available upon
request. MIL-PRF-55681 and Hi Rel screened versions
are also available.

In order to evaluate the tin whisker growth on pure tin and tin lead plated capacitors Johanson Dielectrics performed
tin whisker testing on various sizes of capacitors using iNEMI and JESDA121 test methods.
The following samples were tested:
0805 X7R Pure Matte Tin Finish with nickel barrier
1210 X7R Pure Matte Tin Finish with nickel barrier
1210 X7R Tin Lead Finish with 5% minimum lead content (same lot as pure tin part)
1812 X7R Pure Matte Tin Finish with nickel barrier
Two different tests were performed:
1) Temperature Cycle Test: Temperature Cycle per JESD22-A104 Test Condition A Soak Mode 3 1000 cycles SEM
inspections per JESD22-A121. The parts are temperature cycled from -55C to 85C, with a minimum of 10 minutes
soak time at the minimum and maximum temperatures.
2) Temperature Humidity Test: 4000 hours at 60 C and 93% relative humidity per iNEMI recommendations.
Inspection of whiskers: The capacitors were inspected by SEM before and after each test at 250 and 2500
magnification.
The parts were evaluated to the requirements of Class 2 devices as stipulated by iNEMI ‘Tin Whisker Acceptance
Test Requirements’, July 28, 2004, paragraph 18.2.3. The maximum acceptable whisker length is 40 um.
The whisker length reported is the total axial whisker length as per JEDEC standard JESD22A121 definition 3.1.
Although only whiskers of 10um or greater in length are classified as ‘true’ whiskers as per JEDEC standard
JESD22A121 definition 3.2, whiskers of all lengths are reported below.
