PRODUCT RANGE

Multicore X39 cored wires are manufactured as standard

with a nominal flux content of 1%. SPECIAL PROPERTIES

The uncleaned residues PASS SIR testing to the Bellcore

TR-NWT-000078 issue 3 (December 1991) and IPC Class

1,2 and 3 protocols. They also pass the electromigration

test specified by Bellcore TR-NWT-000078.

Multicore X39 cored wires are available in a variety of

alloys conforming to J-STD-006 and EN 29453 or alloys

conforming to similar national or international standards.

For details refer to document “Properties of Alloys used in

Cored Solder Wires ”. A wide range of wire diameters is

available.

Flux: Multicore X39 solid flux is based on modified rosins

and halide free carboxylic acid activators. In use it has a

mild rosin smell and leaves a small quantity of clear

residue. It may be classified as RO L0 according to J-STD-

004 (January 1995), LR3CN according to IPC-SF-818 or

DIN F-SW32 according to DIN 8511. It meets the

requirements of Bellcore TR-NWT-000078 issue 3

(December 1991).

RECOMMENDED OPERATING CONDITIONS

Soldering iron: Good results should be obtained using a range

of tip temperatures. However, the optimum tip temperature and

heat capacity required for a hand soldering process is a function

of both soldering iron design and the nature of the task and care

should be exercised to avoid unnecessarily high tip temperatures

for excessive times. A high tip temperature will increase any

tendency to flux spitting and it may produce some residue

darkening.

The soldering iron tip should be properly tinned and this may be

achieved using Multicore cored wire. Severely contaminated

soldering iron tips should first be cleaned and pre-tinned using

Multicore Tip Tinner/Cleaner TTC1, then wiped on a clean, damp

sponge before re-tinning with Multicore cored wire.

Soldering process: Multicore cored wires contain a careful

balance of resins and activators to provide clear residues,

maximum activity and high residue reliability, without cleaning in

most situations. To achieve the best results from Multicore solder

wires, recommended working practices for hand soldering should

be observed as follows:

• Apply the soldering iron tip to the work surface, ensuring that

it simultaneously contacts the base material and the

component termination to heat both surfaces adequately.

This process should only take a fraction of a second.

• Apply Multicore flux cored solder wire to a part of the joint

surface away from the soldering iron and allow to flow

sufficiently to form a sound joint fillet – this should be

virtually instantaneous. Do not apply excessive solder or

heat to the joint as this may result in dull, gritty fillets and

excessive or darkened flux residues.

• Remove solder wire from the work piece and then remove

the iron tip.

The total process will be very rapid, depending upon thermal

mass, tip temperature and configuration and the solderability of

the surfaces to be joined.

Multicore flux cored solder wires provide fast soldering on copper

and brass surfaces as well as solder coated materials. The good

thermal stability of Multicore fluxes means they are also well

suited to soldering applications requiring high melting temperature

alloys.

Cleaning: Multicore X39 flux cored wires have been formulated

to leave minimal quantities of flux residue and to resist spitting

and fuming.

Cleaning will not be required in most situations but if necessary

this is best achieved using Multicore MCF800 Cleaner (see

separate technical data sheet). Other proprietary solvent or semi-

aqueous processes may be suitable. Saponification may be

viable but customers must ensure that the desired level of

cleanliness can be achieved by their chosen system

HEALTH AND SAFETY

WARNING: The following information is for guidance only and

users must refer to the Material Safety Data Sheets relevant to

specific Multicore X39 products before use.

Health Hazards and Precautions: Inhalation of the flux fumes given

off during soldering should be avoided. The fumes are irritating to the

throat and respiratory system. Prolonged or repeated exposure to

rosin or modified rosin based flux fumes may lead to the development

of respiratory sensitisation and occupational asthma.

Multicore solder wires must always be used with suitable fume

extraction equipment to remove fumes from the breathing zone of

operators and the general work environment.

Solder alloys containing lead give off negligible fume at normal

soldering temperatures up to 500°C.

Normal handling of lead alloy wires will not cause lead to be

absorbed through the skin. The most likely route of entry is

through ingestion but this will not be significant if a good standard

of personal hygiene is maintained. Eating, drinking and smoking

should not be permitted in the working area. Hands should be

washed with soap and warm water after handling solder wire.

Waste disposal: Wherever possible, waste solder wire should

be recycled for recovery of metal. Otherwise it should be

disposed of according to local or national regulations.
