Soft soldering fluxes - Test methods - Part 17: Surface insulation resistance comb test and electrochemical migration test of flux residues (ISO 9455-17:2002)

ISO 9455-17:2002 specifies a method of testing for deleterious effects that may arise from flux residues after soldering or tinning test coupons. The test is applicable to type 1 and type 2 fluxes in solid or liquid form, or in the form of flux-cored solder wire, solder preforms or solder paste constituted with eutectic or near-eutectic tin/lead solders.
This test method is also applicable to fluxes for use with lead-free solders. However, the soldering temperatures may be adjusted with agreement between tester and customer.

Flussmittel zum Weichlöten - Prüfverfahren - Teil 17: Bestimmung des Widerstandes der Oberflächenisolierung, Kammprüfung und elektrochemische Migrationsprüfung von Flussmittelrückständen (ISO 9455-17:2002)

Dieser Teil der ISO 9455 spezifiziert eine Testmethode zur Ermittlung von Schädigungen, die durch
Flussmittelrückstände nach dem Weichlöten oder nach dem Verzinnen von Proben entstehen. Der Test ist
anwendbar für Flussmittel der Typen 1 und 2, spezifiziert in der ISO 9455-1, in fester oder flüssiger Form, in
Lotdrähten, Lotformteilen oder Lotpasten in Verbindung mit eutektischen oder naheutektischen
Zinn(Sn-)Blei(PB-)Loten (ISO 9453:1990, Klasse E).
ANMERKUNG Diese Testmethode ist auch anwendbar für Flussmittel beim Einsatz von bleifreien Loten. Die
Löttemperaturen sollten jedoch zwischen dem Kunden und dem Testdurchführenden abgestimmt werden.

Flux de brasage tendre - Méthodes d'essai - Partie 17: Essai au peigne et essai de migration électrochimique de résistance d'isolement de surface des résidus de flux (ISO 9455-17:2002)

L'ISO 9455-17:2002 spécifie une méthode d'essai relative aux effets néfastes pouvant être provoqués par des résidus de flux après brasage tendre ou étamage de coupons d'essai. L'essai est applicable aux flux de type 1 et de type 2, tels que spécifiés dans l'ISO 9454-1, sous forme solide ou liquide, ou sous forme de fil d'apport à flux incorporé, de préformes ou de crème à braser constitués de métal d'apport étain/plomb (Sn/Pb) eutectique ou quasi-eutectique.
Cette méthode d'essai est également applicable aux flux à utiliser avec des métaux d'apport de brasage tendre sans plomb. Toutefois, les températures de brasage peuvent être convenues entre le responsable de l'essai et le client.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 9455-17 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 12, Soldering and brazing materials.

Soft soldering fluxes — Test methods —
Part 17:
Surface insulation resistance comb test and electrochemical
migration test of flux residues
1 Scope
This part of ISO 9455 specifies a method of testing for deleterious effects that may arise from flux residues
after soldering or tinning test coupons. The test is applicable to type 1 and type 2 fluxes, as specified in
ISO 9454-1, in solid or liquid form, or in the form of flux-cored solder wire, solder preforms or solder paste
constituted with eutectic or near-eutectic tin/lead (Sn/Pb) solders (ISO 9453:1990, Class E).
NOTE This test method is also applicable to fluxes for use with lead-free solders. However, the soldering
temperatures may be adjusted with agreement between tester and customer.

3 Principle
The objective of this test method is to characterize fluxes by determining the degradation of electrical
resistance and the electrochemical migration of rigid printed wiring coupon specimens after exposure to the
specified flux. This test is carried out at high humidity and heat conditions under bias voltage. For fluxes which
may leave undesirable residues and hence require cleaning, the results obtained from the test will depend on
the characteristics of the flux residue, substrate, metallization, and also on the effectiveness of the cleaning
operation.

ISO 9455-17:2002(E)
The measurement of surface insulation resistance (SIR) makes use of a printed wiring coupon substrate
having one or more conductive interleaved test patterns. Prior to being subjected to conditioning, the
interleaved test patterns are fluxed, soldered or tinned, and cleaned (when required). The patterns are then
exposed to a controlled environment for a specified time, with an applied voltage. The surface insulation
resistance is measured using insulation t
