VI. Reliability Evaluation

A. Accelerated Life Test

The results of the 135

°C biased (static) life test are shown in Table 1. Using these results, the Failure

Rate (

λ) is calculated as follows:

λ =

1

=

1.83

(Chi square value for MTTF upper limit)

MTTF

192 x 4389 x 80 x 2

Temperature Acceleration factor assuming an activation energy of 0.8eV

λ = 13.57 F.I.T. (60% confidence level @ 25°C)

This low failure rate represents data collected from Maxim’s reliability qualification and monitor programs.

Maxim also performs weekly Burn-In on samples from production to assure reliability of its processes.

The

reliability required for lots which receive a burn-in qualification is 59 F.I.T. at a 60% confidence level, which equates

to 3 failures in an 80 piece sample. Maxim performs failure analysis on rejects from lots exceeding this level. The

attached Burn-In Schematic (Spec. # 06-5881) shows the static circuit used for this test. Maxim also performs

1000 hour life test monitors quarterly for each process. This data is published in the Product Reliability Report (RR-

1M).

B. Moisture Resistance Tests

Maxim evaluates pressure pot stress from every assembly process during qualification of each new design.

Pressure Pot testing must pass a 20% LTPD for acceptance.

Additionally, industry standard 85

°C/85%RH or

HAST tests are performed quarterly per device/package family.

C. E.S.D. and Latch-Up Testing

The PD13 die type has been found to have all pins able to withstand a transient pulse of

±2000V, per Mil-

Std-883 Method 3015 (reference attached ESD Test Circuit).

Latch-Up testing has shown that this device

withstands a current of

±250mA.
