High Reliability Space/Medical

SRT-Microcéramique is one of the only two MLCC manufacturers in Europe. Our capacitors are designed, manufactured and screened in Vendôme, France, since 1982, for space, defence and implantable medical programmes. Short lead times, typically 6 to 8 weeks.

A flexible space offer

- PME MLCC, made in Vendôme: 0402 to 80150, 25 V to 15 kV, C0G/NP0, X7R, N2T and High Q; chips, stacks and radial parts. Screening iaw ESCC 3009 or iaw MIL-PRF-55681.
- BME MLCC, sourced AEC-Q200: from 0201, high capacitance, up-screened and fully traced. COTS+ class 1, 2 or 3, or screening iaw ESCC 3009.
- Thin film chip resistors with gold terminations: COTS+ evaluation, screening and lot acceptance testing (LAT), custom qualification.

Screening and evaluation programmes

PROGRAMME	BASIS
D3009	iaw ESCC 3009: evaluation lots (D32) and flight lots (D30), 100 % burn-in 168 h, DPA per lot
D55681	iaw MIL-PRF-55681 (group A)
COTS+	Evaluation, screening and LAT based on ECSS-Q-ST-60-13C Rev.1, class 1, 2 or 3
Custom	Your own specification
Your parts	Screening, LAT and tin whisker mitigation of customer-supplied passive and active parts

Tin whisker mitigation and re-tinning

- Termination change to SnPb on any component, any manufacturer, including high-value BME MLCC.
- Hot solder dipping Sn62Pb36Ag2 or SAC305, electrolytic plating Sn90Pb10.
- Re-tinning of passive components (capacitors, resistors, inductors, thermistors, tantalum) and active components (diodes, transistors, marked parts).
- Gold removal before soldering, tape and reel after treatment.
- Parts re-tinned by SRT fly on satellites, probes and rovers, from Earth orbit to Mars.

In-house test laboratory

Voltage conditioning and burn-in, C, DF, IR and voltage proof, −55 °C / +125 °C characterisation, life test 1000 to 2000 h, 85 °C / 85 % RH, thermal shock, DPA iaw ESCC 23400, visual and dimensional inspection iaw ESCC 20400/20500, solderability and shear tests.

Implantable medical

Twenty years of components for active implantable medical devices: whisker-free SnPb or SAC305 terminations, gold terminations for epoxy and wire bonding, burn-in and full lot traceability, no-obsolescence policy for long-life products. Non-magnetic MLCC for MRI and medical imaging.
