Telecore XL-825 Lead-Free Solder Wire

ALPHA® Telecore XL-825 is a newly developed cored wire that is specifically designed to meet JIS Class AA requirements, with a halide content <1,000ppm, for no-clean lead-free applications.  It offers the balance of high SIR reliability and excellent spread characteristics.  It is among the best performing products in the ALPHA® Cored Wire Product Portfolio.  The pay off is not only an excellent soldering performance XL-825, but also a reliable material that is able to comply to IPC flux ROL1 classification. 

XL-825's fast wetting and low spattering characteristics make it excellent for manual assembly and drag soldering applications. It is safe to use and operator friendly. Inspection is also made easier by its clear residue.

Key Products Features & Benefits: 

  • Very fast wetting → Excellent for “Drag Solder” Technique. High Throughput.
  • Very low flux spatter → Safe to use, Operator Friendly Less Residues on Boards.
  • Good spread characteristics → Excellent First Pass Solder Joints, conferring high throughput. JIS Spread ≥ 80%.
  • Very low levels of fumes →Cleaner Working Environment. Less Extraction Maintenance.
  • Clear non-tacky residue →No-Clean Residues. Useful for all Applications.
  • Provides good joint appearance →Makes Inspection easy.
  • J-STD Classification: ROL1

FAQ's

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.
