The use of BBIEN LF-03 SAC305 as wave solder requires a solder bath temperature of approx.260 to 265☌.The use of inert gas means a significant extension of the process window.The wetting of the solder is made easier and on exit from the wave,no excess solder remains attached to the components.BBIEN LF-03 SAC305 lead free silver wave solder bar can also be used in selective soldering systems. On changing to lead-free production the temperature profile and process conditions for this alloy-like for any other lead free alloys,too-must be adjusted.The resulting solder joints will have comparable or even better characteristics than solder joints,which were made with Sn/Pb solders.During the use in a solder bath the copper content increases with the consequence,that the liquidus of the alloy is rising,causing soldering defects Therefore a regular analytical control of the solder composition is necessary in order to maintain the copper content below 1%. Very good drainage,has lower levels of bridging compared to Sn/Cu alloysĭelivers excellent performance across a wide range of Flux technologies. Wetting speed–fast wetting,in back to back tests 0.65s compared to 1.00s,for Sn/Cu based materialsĭross generation–Low dross generation delivered by Vaculoy alloy conditioningĮxcellent solderability due to fast wetting speed Yield–Best in class yield,out performs all Sn/Cu based materials
Lower cost than eutectic SnAgCu alloy due to 0.8%lower silver content Longer service life due to reduced copper content In electronics manufacturing and guarantees a lead-free wave soldering process. We have seen the swings in the 1970's, 80's and today.Lead free silver wave soldering bar SAC305īBIEN LF-03 SAC305(Sn96.5Ag3.0Cu0.5)is a lead-free solder according to ISOĩ001:2008 which can replace eutectic or almost eutectic tin/lead or tin/lead/silverĪlloys.BBIEN LF-01 SAC305 alloy solder bar is manufactured from pure metals and hasīeen developed to eliminate the use of tin/lead alloys in all existing production processes
When choosing silver bars look to us to provide not only great service and delivery but also the knowledge that 40 years in the business brings. One of the most beautifully crafted bars to come out in the last few years was produced by the Royal Canadian Mint. Recently even countries like Canada & Australia began producing bars. Some of the newer companies producing silver bars in many different sizes and designs are Silvertowne, NTR Metals and PAMP Suisse. Johnson Matthey is also a brand with deep roots in the history of the silver market and has a few older designs that are collectible. These bars are still very common on the secondary market and some designs are rare and collected. These bars will carry the lowest premiums available with the exception of the COMEX (Commodities Exchange) deliverable 1000 ounce bars.Įngelhard is an old and respected silver company that is no longer operating. 100 Ounce - The standard vehicle of serious silver investors is one hundred ounce bars.Normally priced within reach of most people, these bars also make impressive gift items as well. 10 Ounce - One of our most popular items, ten ounce bars are a collector favorite.
Generally it costs the same to produce any bar so the production cost is one-fifth that of the one ounce bar per ounce.
