Specification Brand : Sheicon BulletPoint : Practice Circuit Board with Parts BulletPoint1 : 1.1 Lb each Tin Bar. Made of new material,do not add the recovery of tin ,tin slag.This products compliant ROHS. BulletPoint2 : Good wettability and extension ability, solder joint full light, effectively prevent bridge, icicles,virtual false welding welding phenomenon. BulletPoint3 : Adding high-effective antioxidant ingredients, strong antioxidant capacity, Tin slag less, reduce energy consumption, reduce unnecessary waste. BulletPoint4 : Suitable for wave soldering or hand immersion soldering,Welding intensive circuit board, superior performance and high reliability. BulletPoint5 : ATTENTION: all tin bars are printed with Sn63%A, which is not represent the actual tin content. It is just a mold issue. Please select the actual tin content according to the style option.

The Tin content of solder rods are 20-99.9%. Please purchase solder rods with corresponding tin content according to their respective purposes to achieve the effect of use.
Tin content 55-99.9%, for high requirements: welding of high-precision instruments, electronics industry, circuit boards (high requirements), communications, micro-technology, aviation industry, etc.
Tin content 40-50%, for general requirements: welding of home appliances, electrical appliances, meters, circuit boards (general requirements) automotive electrical appliances, general hardware appliances, etc.
Tin content 20-35%, for lower requirements: general mechanical welding, welding of automobile water tanks, light bulbs, cable joints, etc.
The tin bar with the higher tin content, the brighter the tin bar, the easier it is to tin, and the brighter the solder joints.
