Lets take a peak first on how a lead could manage to destroy an environment and to human being. There is no really visible damage contribution to it but the effect is through its contribution of elements in the air (specifically the melting copper).
The impact categories included in the Lead-Free Solder Project [LFSP] and life-cycle impact assessment [LCIA] are as follows: renewable resource use, nonrenewable materials use, energy use, landfill space use, global warming, stratospheric ozone depletion, photochemical smog, air acidification, Solder Bar air particulates, water eutrophication (nutrient enrichment), water quality (biological oxygen demand [BOD] and total suspended solids [TSS]), occupational human health effects (cancer and non-cancer), public human health effects (cancer and non-cancer), and aquatic ecotoxicity.
Here is a solder flux paste to a least minimize the toxic content of the lead that may cause damage to environment and human body. This is a solder flux paste that can be used on steel, iron, braze, plated-zinc, and plated-nickel soldering for general purposes. Xihan solder flux paste is a product into it. Xihan, is based in Ningbo, Shanghai, China and exports quality solder flux paste to any part of the world. So how can interested buyers contact Xihan? They provide a site on web to contact them and know more about the product. It can be ordered in hundreds for they can accommodate 3000 pieces-per-day order and they never ran out of stock. Worth $0.6-0.8/pc, you can have them on time.
Impacts from the transportation and distribution of materials, products, and wastes throughout the life-cycle of a solder are included in most of the upstream processes where secondary data are used that already include transportation. Like Xihan, they also make provide time frame in delivery not long enough to wait but not fast enough to surprise you… they consider seven to ten working days delivery time. Data for manufacturing and use/application life-cycle stages reflect the period stated.
Unlike most products, solder does not have a use life-cycle that extends over a large time frame, instead it occurs over the relatively short period of time required to assemble a printed wiring board. And to whatever business anyone ventures, please also understand any risk that takes part of it. No matter what kind of industrial business we are in. Always remember that anything should also be of good service not just to your client but also to the nature, who deserves much credit to our existence.
