GR402
The recommended Low Residue solder wire for all professional
soldering applications.
Our
latest improved Ultra Low Residue Solder Wire Range leaves clear
residues which are non corrosive.
Non
corrosive residues as per Bellcore TR-TSY-000078, B.S. 5625, B.S.
441, DTD 599A, and QQS 571E
.
GR402
offers versatility of product selection allowing the consumer to
determine an acceptable specification of Solder Wire.
GR402
Solder Wire is designed to meet individual requirements of product
service life, speed of soldering and acceptable residue levels.
Other
High Purity Solder alloys in the range include: Sn60 Pb40, Sn63 Pb37
and Sn62 Ag2 Pb36
GENERAL
CHARACTERISTICS
GR402
is classified as no-clean, for all applications including wave
solder and surface mount re-work. GR402 flux is based on modified
rosins which leave minimal residues.
PHYSICAL
CHARACTERISTICS
GR402
flux leaves clear residues which are non corrosive. Solderability on
copper substrates is good and excellent on tin plated surfaces.

STORAGE
and USE
Store
in normal conditions at room temperature.
Avoid excessive inhalation of fumes.
These are irritating to throat and respiratory organs. Prolonged or
repeated exposure may rarely result in sensitisation leading to
occupational asthma. Suitable fume extraction equipment should be
used to extract flux fumes away from operators. (This important
issue is also catered for, please contact sales for information and
prices etc..)
Lead is harmful if absorbed into the
body through the digestive system or skin. Eating, drinking and
smoking should not be permitted in the working area. Hands should be
washed with soap and warm water after handling solder, especially
before eating.
The tip of the soldering iron should
be properly tinned and this may be achieved with 402 solder
wire. However, this does depend on the initial condition of the tip.
If it is in poor condition, it may be more effective to pre-tin the
tip with Tip Cleaner. Used correctly, this cleaner will leave the
iron tip well tinned and free from any harmful residues which might
be transferred to the work piece. For additional details
contact Sales.
For best results use an
iron tip temperature between 340 - 420 °C.
