Compliance
Ask us for the certificates and reports of the exact part you need. Typical documents:
- RoHS compliance declaration
- LM-80 lumen maintenance report for the LED light source
- Photobiological safety assessment to EN 62471 / IEC TR 62778
- Reliability test results to JEDEC JESD22 methods
Reliability tests
Reliability tests follow JEDEC JESD22 methods, with 22 pieces per test. Example: the test plan of the CER3535 A22 series.
| Test | Standard | Conditions | Duration |
|---|---|---|---|
| High-temperature storage | JESD22-A103 | 100 ± 5 °C | 1000 h |
| Low-temperature storage | JESD22-A119 | −40 ± 5 °C | 1000 h |
| Thermal shock | JESD22-A104 | 100 °C, 30 min ↔ −40 °C, 30 min (15 s transfer) | 1000 cycles |
| Reflow | JESD22-B106 | Peak 260 °C for 10 s | 3 cycles |
| Life test | JESD22-A108 | Ta = 25 ± 5 °C, IF = 1500 mA | 1000 h |
| High-temperature life test | JESD22-A108 | Ta = 105 ± 5 °C, IF = 1500 mA | 1000 h |
| High temperature and humidity life test | JESD22-A101 | 85 ± 5 °C / 85 % RH, IF = 1500 mA | 1000 h |
Storage and handling
- Store unopened bags at 5–30 °C and no more than 50 % RH. If stored for more than 3 months, bake at 65 °C for 24 hours before use.
- After opening a bag, solder the parts within 12 hours. Keep the rest sealed, or at 5–40 °C and no more than 30 % RH.
- If a bag has been open for 24 to 168 hours, or its humidity card has turned from blue to pink, bake at 65 °C for 24 hours. After 168 hours, take the parts off the tape and bake at 150 °C for 2 hours.
- Reflow no more than twice, following the profile in the part’s datasheet.
- Hold parts by their sides with tweezers. Do not press the silicone lens or stack assembled boards.
- Use ESD protection: wrist straps or anti-static gloves, and grounded equipment.
- Keep parts away from corrosive gases, which can discolour the silver-plated leadframe.
