Xihan solder bar are manufactured by most advanced continuous casting and extrusion machines.Quality control is strictly done in our modern laboratory with lastest model of impurities analysis equipment.
solder bar are available both casted type and extrusion type.
Xihan Solder bar utilizes 100% processed electroplate tin and high purity silver, copper and nickel alloys. Compared with the traditional Sn-Pb solder , lead-free solder has less better wetting , easily oxidized, and results in the tin tassels. In order to over come the weakness, we have made a deep and long-term research and in the technology, we use deoxidation and dedrossing prosess and add special anti-oxidation elements. In this way, the weakness is basically resolved, which reduces the tin-dross and promote the solderability.
The popular anti-oxidation solder bar consists of 300-400 ℃ and 250-300℃ according to its working temperature. The first 300-400℃ is suitable for the static dip soldering and 250-300℃ is for wave soldering and had-holding dip soldering.
All the solder bar's metal elements are superior than GB/T80,L-200,GB/T3131-2001 China, JIS-Z-3283, Japan and QQ-S-571F, America standards. The above-mentioned method reduces the viscosity and oxidation on the surface and promotes the wetting and mechanical strength. And the soldering spots are full and nice in good shape with minimum dross.
Our factory have two solder bar 300-430℃ and 200-300℃ anti-oxidation according to its working temperature.
(1). 200-300℃ anti-oxidation solder bar designed for wave and dip soldering . And the dross amount is only 1/2-1/3 of the somilar products on the market.
(2). 300-430℃ anti-oxidation solder bar designed for dip soldering. It is suitable for electronic transformer. Relay, and electornic led tinning processing . etc. the static melt solder serface keeps long-time mirror plate.
