Worldwide, more than 328,000 end-of-life notifications for electronic components were registered in 2023 alone – a third of them with no prior warning. Semiconductors are discontinued after just 7 to 10 years today, while the devices they power stay in service for 10 to 20 years – and considerably longer for vehicles under statutory aftermarket-parts obligations. That gap can't be argued away, only bridged.
btv long-term storage closes exactly that gap: tested, documented, and independently validated. A component stored incorrectly for three years can look brand-new at goods-in – and still fail in the field. Value retention in electronic components only shows up years later, not on the day of storage intake

Long-Term Conservation to DIN EN IEC 62435 – Our Storage for Your Electronic Components
Our long-term storage goes beyond DIN EN IEC 62435 – with tailored protective measures, additional controls, and digital monitoring. At its core is a fixed repacking cycle: components are systematically repackaged every two years, well before the three-year minimum shelf life of moisture barrier bags expires.
Our long-term storage is also independently tested: the Fraunhofer Institute for Silicon Technology (ISIT) has been storing SMD components since the year 2000 and confirms that even after extreme aging, no wetting deficiencies appear in the reflow process – a track record spanning more than two decades.
How Your Long-Term Storage Works at btv technologies
- Risk analysis: which components are affected by discontinuation, and how long does supply need to last?
- Volume calculation: demand for the remaining service life, based on BOM and demand analysis.
- Storage intake: verification of identity, quantity, and original packaging, additional protection via ESD and moisture barrier bags.
- Ongoing protection cycle: repacking every two years, regular power cycling and functional testing.
- Demand-driven delivery: call-off across the full contract term, with full traceability on every movement.
Three Protection Tiers Compared
| Element | btv Standard Storage | Long-Term Storage | btv LONGEVITY® |
| Storage horizon | up to approx. 2 years | 3–15 years | over 50 years |
| Protection | Climate-controlled, ESD-safe, FM Global fire protection | Nitrogen atmosphere, vacuum sealing, intelligent repacking | Long-term storage standard + anti-off-gassing bag with sacrificial material |
| Validation | Exceeds EN 62435 | Fraunhofer ISIT testing since 2000 | Inherits validated long-term storage baseline |
| Traceability | Full packaging-unit-level traceability, 30-year archiving | identical | identical |
Why Long-Term Storage for Electronics Determines the Operational Reliability of Your Products
Many manufacturers store control units or microchips on standard shelving once discontinuation looms – without moisture, ESD, or temperature protection. That saves money short-term but only shifts the risk to a later, uncontrolled point in time.
The Risks of Unprotected Component Storage
- Humidity causes oxidation and diffusion at component leads – the result is solderability failures that often only surface at the point of assembly.
- ESD damage is frequently latent: invisible at storage intake, but the cause of early-life failures once the part is in the field.
- Components also continue to age chemically even when packaged and powered off – "keep it dry" alone isn't enough.
- Without a power-cycling regime, control units additionally face capacitor aging and cold-joint risk.
The effect runs through the entire assembly: a failed microchip disables the circuit board, a failed circuit board disables the control unit, and a failed control unit can disable the entire end product. btv Standard Storage is already ESD-safe, climate-controlled, and FM Global fire-protected – the baseline that unprotected, concept-free storage skips from the start.
Reference – 86,500 Control Units, Zero Field Failures After 15 Years of Long-Term Storage
A Tier-1 automotive supplier faced a classic obsolescence problem: a 15-year statutory spare-parts obligation for a vehicle control unit, but the microcontroller inside it was going end-of-life after just 7 years. 86,500 control units across two product variants were affected. The redesign alternative would have cost €700,000.
The chosen path: end-of-life production to EN 62435+, storage under nitrogen atmosphere with repacking every two years, a power-cycling regime against capacitor aging, and demand-driven delivery across the full 15-year term. Result: zero field failures, roughly 40 percent cost savings versus the redesign option, and every IATF 16949 audit passed without a single finding.
