Leaded 63/37 Solid Solder Feed Wire

63/37 Solid Solder Wire is manufactured using ultra high purity raw materials and the alloy is conditioned using Alpha's proprietary viscosity and dross lowering treatments. This results in a pure, low drossing, high fluidity solder alloy, which is free of cast-in impurities and included oxides.

These larger diameter feed wires have been designed with selective  soldering in mind. The solder wire is manufactured to high tolerances  and wound onto 4 kg reels at a constant tension to ensure a smooth take  off through the machine feed mechanism into the solder pot.

Key Products Features & Benefits: 

  • Increases Production Speed: which means lower product costs
  • Minimises drossing: lowers downtime for maintenance and reduced solder consumption and costs.
  • Reduces bridging: lower amount of rework to higher yield, lowers cost and reduces chances of defects getting to consumer.
  • Solders densely populated boards: can be used on all your applications, you only need to stock one grade.
  • Solders at a lower temperature: lower temperatures mean less oxide production and hence lower solder usage and cost.

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.
