This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at

31、the latest by April 2015, and conflicting national standards shall be withdrawn at the latest by April 2015.

This document has been developed to cover specifically space systems and has therefore precedence over any E

35、DIN EN 16602-70-07:2015-01 EN 16602-70-07:2014 (E) 5 Introduction Wave soldering is regarded as a critical process that can find limited application during the assembly of components on to printed circuit boards (PCBs) intended for spacecraft. The preferred procedure is by manual soldering to the re

36、quirements of ECSS-Q-ST-70-08. Generally the small number of identically designed circuits does not warrant the setting up of unique machine parameters for each individual layout. When wave soldering is identified as a suitable alternative to manual soldering for use in the customers projects, it ca

37、n be essential to follow the steps outlined in this document before the final customers approval is granted. The sequence of main events is shown in Figure 4-1. Each step is fully completed and the details recorded, so that a dossier is compiled for each manufacturers assembly line. All dossiers are

38、 kept updated by the approval authority and serve as a reference for the approval authoritys Project Engineers. A general qualification is not granted for wave soldering. Wave soldering lines that have been previously verified (see also clause 5.2) can be also approved for use on named projects, but

39、 this depends entirely on the specific project requirements. Project process approval is requested, as for all materials and critical processes, by means of ECSS-Q-ST-70. DIN EN 16602-70-07:2015-01 EN 16602-70-07:2014 (E) 6 1 Scope This specification defines the basic requirements for the verificati

40、on and approval of automatic machine wave soldering for use in spacecraft hardware. The process requirements for wave soldering of double-sided and multilayer boards are also defined. This standard may be tailored for the specific characteristic and constrains of a space project in conformance with

47、 notifying, renewing or withdrawing the approval of the verification NOTE The approval authority is the final customer or the representative nominated by him. For example, for ESA programmes, the final customer is ESA. 3.2.2 component density number of components per unit board area 3.2.3 ionisable

49、 serve primarily to provide a barrier between the atmosphere and molten solder, thereby reducing the oxidation (drossing) of the solder. Certain oils also reduce the surface tension of molten solder, thereby enhancing the wetting characteristics of the solder.
