Solder Sticks And Bars |
Sticks, Bars and Anodes
Solder Sticks / Bars
Alloys in the form of Solder Sticks / Extruded Bars / Ingots are manufactured using virgin metals conforming to Indian and International specifications. It can be supplied in any Tin / Lead composition for all applications including wave soldering. Popular alloy composition is 63 / 37 (Tin / Lead), which is a Eutectic composition (Melting at 183° C) and 60 / 40 (Tin / Lead) sticks.
Pure Tin Anodes and Tin/ Lead Anodes
Manufactured using highest purity metals in pure Tin and any solder alloy compositions. The most popular are 60/40 alloys. Ideal for plating of copper conductors on printed circuit Boards to extend shelf life.
Use of virgin metals and control of metallic impurities to a minimum level in manufacturing process results in optimum performance of anodes. Excessive metallic impurities in plating anodes can cause sludge formation on anodes, necking of anodes, darkening of the deposited electroplate and inferior re-flow characteristics of the deposit. Strict control on the Tin content of anodes provides added reliability.
Casting is normally the most economical method for fabricating Tin and Tin/Lead plating anodes. The major disadvantage is that excessive grain growth due to slow cooling and alloy segregation may result. The preferred method for anode manufacture is extrusion. BT Plating Anodes are extruded under high pressure, which assures a dense, fine grain structure with continuous uniformity. Uniform dissolution of the anode in the plating bath results, with necking reduced to a minimum. The fine grain size permits the use of higher current densities without making the anodes passive.
The high purity and uniformity of BT Plating Anodes provides improved anode efficiency. This means a longer anode life, fewer chemical additions to the plating bath, better soldering of plated parts and an overall economy in use.

Solvent Cleaners |
Solvent Cleaners
Characteristics
WS-24 SOLVENT CLEANER is a blend of polar and non-polar solvents ideally suited for cold cleaning utilizing ultrasonic agitations and wave or bottom brush equipment. The non polar component effectively removes non ionic solids such as soldering oils and rosin flux residues where as the polar components dissolves ionic contaminants such as flux activators which if left on printed circuit boards can cause current leakage and corrosion under humid environmental conditions. The cleaner is completely stabilized against thermal and chemical breakdown.
WS-24 boils at a temperature much higher than the customary Fluorinated solvents (about 46C) and chlorinated solvents (about 72C) as a result of which the solvent evaporation rate at room temperature is substantially lower making it highly economical to use.
The cleaner is non-flammable and non-combustible and therefore extremely safe to use.
Application
Though most types of component materials and markings are not affected by WS-24, some plastics are, such as Polystyrenes and Polycarbonates. It is therefore necessary to establish solvent component capability prior to use.
Properties
- Appearance - Clear, Mobile Liquid
- Specific Gravity at 25 Deg. Cent - 1.505 +/-0.015
- Boiling Point - 116C(240.8F)
- Freezing Point - 0C(32F)
- Evaporation Rate (Ether =1) - 0.16
Health & Safety
Though WS-24 does not have an objectionable odor, a well ventilated working area is necessary. Splashing on skin should be removed by washing with soap and water. If the material comes in contact with the eyes, they should be irrigated thoroughly with running water for at least 10 minutes. In extreme cases medical attention should be sought.

Rosin Foam Flux - WS31
Characteristics
WS31 Rosin Foam Flux is an activated, Non-Corrosive Rosin based liquid flux, which has been specially formulated to reduce Icicles and bridging to a minimum on PCB. The minimal residues left on the boards are non-sticky, protective and non-corrosive. WS 32 & WS 38 are Rosin mildly activated flux with different solid contents. It can also be offered in various solid content.
Application
ROSIN Liquid Flux can be used for the Wave/Dip/Spray soldering of all printed circuit boards to give fast production speeds and reliable soldering. Because of its special action of suppressing Icicles and bridging, it will be found that soldering machine setting are not so critical as with other Rosin based fluxes.
Flux Control
The concentration of Rosin based flux increases during usage because of loss of the solvent. The concentration of the flux can easily be maintained by replacing the lost solvent periodically with WS 71 thinner. The specific gravity of the modified solution is monitored by using Hydrometer until it reaches required specific gravity.
Removal Of Flux Residue
Due to its solid content, this flux leaves only traces of non-corrosive residues. If removal of the residues becomes necessary, it can be done by washing with commercial solvent mixture. All known cleaning processes can be employed.

It is important to remove moisture from the air supply as Water absorption can affect soldering performances.
Pre-Heat Temperature
To be maintained minimum 115° C on the top side of PCB. Lower Pre-heat temperature shall give room for white residue.
Flux Control
The specific gravity of the flux should be monitored with hydrometer. If the specific gravity of the flux is above 0.795, due to loss of solvent the concentration of the flux can easily be maintained by addition of thinner. The specific gravity of the modified solution is monitored by using hydrometer until it reaches the required specific gravity.
Removal of Flux Residue
Due to lower solid content, it leaves only traces of non-corrosive residue which can normally be left on the surface. Should removal of the residues be necessary, all known cleaning process can be employed.
