TABLE OF CONTENTS The following table gives rates per million hours showing the highest and lowest values likely to be quoted in data bases. The middle column is the geometric mean (Section 4.3). Each group of three columns is labelled for a junction temperature range in degrees Centigrade. The following multipliers apply:
| Multiplier | |
|---|---|
| QUALITY | |
| Normal commercial procurement | 2 |
| Procured to some agreed specification and | 1 |
| Quality management system 100% screening and burn-in | 0.4 |
| ENVIRONMENT | |
| Dormant (little stress) | 0.1 |
| Benign (e.g. air-conditioned) | 0.5 |
| Fixed ground (no adverse vibration, temperature cycling, etc.) | 1 |
| Mobile/portable | 4 |
| PACKAGING | |
| Ceramic | 1 |
| Plastic | 1 for quality factor 0.4 |
| 2 for quality factors 1 or 2 |
| Note | FARADIP.THREE (see Chapter 4) is updated regularly and values will change slightly. These values are from around a year 2000 version. |
