Space product assurance - High-reliability soldering for surface-mount and mixed technology
This Standard defines the technical requirements and quality assurance provisions for the manufacture and verification of high-reliability electronic circuits based on surface mounted device (SMD) and mixed technology.
The Standard defines acceptance and rejection criteria for high-reliability manufacture of surface-mount and mixed-technology circuit assemblies intended to withstand normal terrestrial conditions and the vibrational g loads and environment imposed by space flight.
The proper tools, correct materials, design and workmanship are covered by this document. Workmanship standards are included to permit discrimination between proper and improper work.
The assembly of leaded devices to through-hole terminations and general soldering principles are covered in ECSS-Q-ST-70-08.
Requirements related to printed circuit boards are contained in ECSS-Q-ST-70 10, ECSS-Q-ST-70-11 and ECSS-Q-ST-70-12 . The mounting and supporting of devices, terminals and conductors prescribed herein applies to assemblies at PCB level designed to continuously operate over the mission within the temperature limits of -55 C to +85 C.
For temperatures outside this normal range, special design, verification and qualification testing is performed to ensure the necessary environmental survival capability.
Special thermal heat sinks are applied to devices having high thermal dissipation (e.g. junction temperatures of 110 C, power transistors) in order to ensure that solder joints do not exceed 85 C.
Verification of SMD assembly processes is made on test vehicles (surface mount verification samples). Temperature cycling ensures the operational lifetime for spacecraft. However, mechanical testing only indicates SMD reliability as it is unlikely that the test vehicle represents every flight configuration.
This Standard does not cover the qualification and acceptance of the EQM and FM equipment with surface-mount and mixed-technology.
The qualification and acceptance tests of equipment manufactured in accordance with this Standard are covered by ECSS-E-ST-10-03.
This standard may be tailored for the specific characteristics and constraints of a space project, in accordance with ECSS-S-ST-00.

Zagotavljanje kakovosti proizvodov v vesoljski tehniki - Visoka zanesljivost spajkanja za površinsko montažo in mešano tehnologijo
Ta standard opredeljuje tehnične zahteve in določbe za zagotavljanje kakovosti za proizvodnjo in preverjanje visoko zanesljivih elektronskih vezij na podlagi površinsko montiranih elementov (SMD) in mešane tehnologije.
Standard določa merila za sprejem ali zavrnitev za visoko zanesljivo proizvodnjo površinsko montiranih sestavov vezij z mešano tehnologijo, ki naj bi prenesli običajne zemeljske pogoje in vibracijske obremenitve zaradi pospeška ter okolje, ki jih povzročijo vesoljski poleti.
Ta dokument obravnava ustrezna orodja, pravilne materiale, zasnovo in izvedbo. Izvedbeni standardi so vključeni, da se omogoči ločevanje med primernim in neprimernim delom.
Sestav osvinčenih elementov, terminali z luknjo in splošna načela spajkanja so zajeti v standardu ECSS-Q-ST-70-08.
Zahteve v zvezi s ploščami tiskanih vezij so podane v standardih ECSS-Q-ST-70 10, ECSS-Q-ST-70-11 in ECSS-Q-ST-70-12. Nameščanje in podpiranje komponent, terminalov in prevodnikov iz tega standarda se uporablja za sestave, namenjene delovanju v okviru temperaturnega razpona –55 C do +85 C.
Pri temperaturah zunaj tega običajnega razpona se izvede posebno preskušanje zasnove, preverjanja in kvalifikacij, da se zagotovi potrebna okoljska zmožnost preživetja.
Posebni toplotni ponori se uporabljajo za naprave z visokim toplotnim odvajanjem (npr. temperature stika 110 C, močnostni tranzistor), da se zagotovi, da spojeni spoji ne presežejo 85 C.
Preverjanje postopkov sestavov površinsko montiranih elementov se izvaja na testnih plovilih (vzorci preverjanja površinske montaže). Ciklične temperaturne spremembe zagotavljajo operativno življenjsko dobo vesoljskega plovila. Vendar pa mehansko preskušanje podaja samo zanesljivost površinsko montiranih elementov, saj je malo verjetno, da testno plovilo predstavlja konfiguracijo vsakega leta.
Ta standard ne zajema kvalifikacije in sprejemljivosti opreme EQM in FM s površinsko montažo in mešano tehnologijo.
Kvalifikacijski in sprejemljivostni preskusi opreme, izdelane v skladu s tem standardom, so obravnavani v standardu ECSS-E-ST-10-03.
Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.
