Clean wave soldering or reflow process or to allow repairs
to cleaned boards without the need for a second cleaning
process. Should residue quantity be an important
consideration, Multicore X39 flux cored wire may be
specified if a halide free product is required or X52 if halide
may be tolerated. Crystal 500, 502, 505 and 511 offer
good activity and consequently cored wire flux contents
and hence residue levels may be reduced in comparison
with equivalent conventional products.
Multicore Prozone Solvent Cleaner (separate data sheet
available). Other proprietary solvent or semi-aqueous processes
may be suitable but saponification is not recommended.
A full description of test methods and detailed test results
are available on request.
Alloys: The alloys used for Crystal cored solder wires
conform to the purity requirements of the common national
and international standards. A wide range of wire diameters
is available manufactured to close dimensional tolerances.
Flux: Multicore Crystal solid fluxes are based on modified
rosins and carefully selected activators. In use they exhibit
a mild rosin odour and leave a small quantity of clear
residue.
Cored wire: Multicore Crystal cored solder wires are
designed to give fast and sustained wetting on both copper
and brass. This can be demonstrated using spreading tests
on both substrates under standard conditions for the
Multicore products and comparable competitor products.
After 5 seconds, area of spread is measured to form a
comparative index indicating total flux efficacy.
competitor products, which required a higher flux content
and leave more residues whilst achieving poorer spread.

WARNING: The following information is for guidance only
and users must refer to the Material Safety Data Sheets
relevant to specific Multicore Crystal flux cored solder
wires before use.
Fume Hazards and Precautions: Avoid excessive
inhalation of the flux fumes. These are irritating to the
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.
Protection and Hygiene: 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.
