S64 - High Temperature Flux

Alpha® S64 is a liquid activated rosin flux, which can be used for dip-tinning of component leads as well as for conventional wave and hand soldering. It is a clear solution of a modified rosin with a fast acting activator package which provides a rapid cleaning action and excellent wetting. As the activator is fully soluble in the solid rosin, the post solder residues are in the form of a solid homogeneous coating which is free from corrosive or hygroscopic inclusions.

FAQ's

Q - Can this flux be used for high temperature solder dipping?
A - This flux is suitable for use up to 400 oC. Ideal for transformers and chokes where the wire coating needs to be melted away during the soldering process.

Q - I need to find a suitable solder alloy that will work around 380 C - 420 C is there one?
A - The favorite among many customers is the Alpha Fry LS4. This can be supplied in Bar, tinmans or wire depending on your application.

Q - Are the flux residues corrosive after soldering?
A - No. The residues after soldering are neither hydroscopic nor corrosive to the finished product.

Q - If the flux gets too thick for the application can l thin it down back to the correct specific gravity?
A - Use Alpha 425 thinners to restore the flux back to manufacturers specification which is 0.905

Q - What is colophony and can it cause any health issues?
A - Colophony is a generic term for rosin, this is the sap or sticky substance that derives from pine and spruce trees. Its "stickiness" lends itself to being used in a wide range of products. We have traditionally used this product in fluxes due to these specific properties it can however lead to breathing difficulties and skin sensitivity. Always use fume filtration when soldering and change filters regularly.

Q - What is the difference between rosins and resins?
A - The terms are often used interchangeably, but rosin is a naturally occurring substance, and resin is either a modified rosin or completely synthetic material. Rosins are plant based products and are subject to more natural variation than resins, however resins are commonly used in newer flux formulations due to their more consistent performance.

Q - How does IPCJ-STD-004B flux classification work.
A - Flux designation has three components. The first two letters, RO, RE or OR, represent the basic chemical composition: rosin-based, resin-based or organic acid-based. The next component is flux designation, L, M or H, which describes the flux’s activity level as low, medium or high, and the final component, 0 or 1, this indicates if halides are present.
