ALPHA® EF-6100 is a high-reliability, IPC, Bellcore, and JIS compliant, low solids, no-clean flux. It is specifically developed to deliver high reliability and excellent soldering performance combined with outstanding board cosmetics and pin-testability. ALPHA EF-6100 exhibits a low tendency for solder ball generation over a wide variety of solder masks during wave soldering and Selective Soldering operations. ALPHA EF-6100 should be considered for use by any assembler who has board designs which require high reliability, good through-hole-fill, reduced component bridging and reduced skips.

Health & Safety
Q - What does Halide free mean?
A - In many fluxes halides are added to the activation package to promote solderability. In the case of this flux solderability and wetting has been achieved using a range of chemistries which do not contain halides. The inclusion of halides within a flux can promote post soldering residues to become active in the presence of moisture and temperature fluctuations and promote corrosion long term which in turn can cause pcb failure.
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.
