What is acid paste flux SP 30?

Kester Soldering Paste Flux SP-30 is a suspension of a zinc chloride solution in petrolatum. It is a highly active flux designed for general soldering requirements. Rapid soldering can be accomplished on most metal surfaces, except aluminum and stainless steel.

What is flux in solder paste?

Solder paste flux is a gelatinous chemical compound used mainly in combination with solder powder to create solder paste, generally mixed as a 50/50 ratio. Once combined, the paste is a gray, putty-like material. Solder paste flux serves a threefold purpose: Removing any oxidized metal from the surfaces to be soldered.

What is rosin paste flux used for?

Rosin flux is used to facilitate soldering. It cleans and prevents metal oxidation which allows solder to create strong, long lasting mechanical and electrical bonds. It also acts as a wetting agent, increasing the flow of solder and the efficiency of the soldering process.

Can you use a paperclip as solder?

Apparently paperclips are also made of galvanised steel as a rule, so there may be a connection here. Other metals such as aluminium or regular steel can be soldered, but require special solder and flux and may need stronger equipment.

Can I solder without flux?

Yes, solder can be used without flux. To do so, you will need something other than flux to break down the oxides on the metal surface, without which your surface may be damaged or not properly cleaned.

Is the Kester SP-30 too corrosive for soldering?

Like other inorganic acid fluxes, Kester SP-30 is too corrosive for electrical or electronics soldering applications. In all cases, the flux residue should be removed after soldering to avoid any corrosion problem. Did I just buy plumber’s flux instead of electronics flux?

How are Flux Density Control Data sheets used in Kester?

Kester has flux density control Data Sheets (also called nomographs) for the rosin and higher solid content fluxes. Using the nomograph you can determine how much thinner needs to be added. We sell test kits for the low residue fluxes. The test kits indicate how much thinner to add to the flux pot.

When to use Kester acid cored solder wire?

Kester Acid-Cored Wire is a highly active, inorganic acid type of flux developed for general-purpose soldering applications where a flux-cored solder wire is desirable. Rapid soldering can be accomplished on all common metals except aluminum and manganese. Acid flux is particularly useful for soldering excessively oxidized metals.

What should the water temperature be for a Kester Assembly?

This will lead to ‘catastrophic failure’ of the assembly in question. We recommend cleaning with an aqueous cleaning system, it can be either batch type or in-line. The water temperature should be between 120-140°F. The important thing is to have lots of rinsing and flushing to completely remove all the flux residues.
