Packing of Lead Free Solder Wire SAC0307:

1. SAC0307 (Sn99Ag0.3Cu0.7) solder wire is available in different weight of reel & different wire diameter, thus we also have various ways of packing. We have small reel such as 100g 200g 250g etc, also we have big reel of 500g & 1000g etc. For commercial use or manufacturing use, generally bigger reel is better because the wires will be consumed very quickly, but if just for small applications such as some DIY use or home use we recommend to buy small reels.

2. Small size reel is generally packed at 20pcs/box (such as 100g/spool, 200g/spool). Big size spool is generally packed 10pcs/box (such as 500g/spool, 1000g/spool).

3. Outer packing is carton, the boxes of solder wires will be stacked into cartons for better protection and easy handling.

4. Eventually plastic pallets would be used to load the boxes, suitable for folk-lift operation and make it easier for shipping.

5. We accept do do client's own private labeling and OEM.
