Solder Dross Recycling ? The Reasons to Consider It
If you are a PCB assembly expert, you are most likely familiar with the layer of metal that accumulates on molten solder’s smooth surface called solder dross. The material is made of impurities and oxidized metals that naturally gather when molten solder becomes exposed to air and the manufacturing environment. Solder dross is unavoidable, regardless of what alloy is being used. Solder dross is normal in the process of PCB assembly and wave soldering and typically accounts for up to 50% of bar solder in a solder pot. Dross used to be considered as waste, but with the advancement in dross...

Solder Dross Recycling
The wave soldering process can produce a significant amount of solder dross, which is formed as molten metals that are exposed to oxygen. Dross is mainly composed of an oxide and solid metal. The oxide contains metal, which can be recovered and recycled. If you use wave soldering for PCB assembly, chances are, you have encountered that chunky metal layer that accumulates on the molten solder’s smooth surface. While dross contains impurities, the oxidized metals are still considered valuable, since it is composed of at least 90% metal. Both lead-free and tin/lead-based processing can resu...

Know More about Low Melting Point Solder
As the name itself explains, low melting point solder is a solder metal which has a low melting point, typically below 200o C. Low melting point solders are extensively used in the electronics industries, typically in applications where high temperatures are likely to damage the materials of the electronic components. Their uses and importance in the electronics manufacture industry is truly unmatched. In this article, we will help you know more about low melting point solders and how they are done. Low temperature solderingSome special manufacturing requirements may necessitate the use of low...

Equipment Required to Liquid Solder Printed Circuit Boards
Due to the shift in soldering techniques and decline in need for through-hole devices, many new types of soldering equipment for PCB assemblies have been introduced in the last few years. Knowing which equipment to use for certain soldering applications will ensure a successful and efficient PCB for modern electronic devices. Liquid solder, for instance, is one of the commonly used fluxes for selective applications. A liquid soldering flux may increase yield and throughput, while adding value to the selective soldering process. The following are the different equipment required to liquid solde...

Know more about the effective Ways to Decrease Carbon Footprint in Cored Solder
Carbon footprint is usually defined as the amount of carbon dioxide equivalents any process, organization, or industry ejects into the atmosphere. Basically, it is a measure of pollution caused to the environment by any process that takes place. Carbon footprint is a concept which has enabled measurement of pollution caused by various industries, quantify it in terms of carbon dioxide, and penalize the excessive producers for contributing more pollution to the environment. This article focuses on the ways with which you can decrease the carbon footprint of cored solder wires.The electronics in...

Work Role of Different Kinds of Soldering Torches
Brazing refers to the joining of two metals. It is easy to do and substitute the welding part quite efficiently. It most often makes use of torches to join two metals. Propane torches are one such equipment which is popularly used for brazing. These can be easily sourced from any of the hardware store or a plumbing supply house. The very first step in propane brazing is to clean the metal that you plan to braze. For cleaning, one can make use of sandpaper to remove oxidation while acetone should be used to get rid of grease. Also, use simple soap and water solution to remove the remaining dust...

Tips on How to Choose a Lead-Free Solder Wire
Solder used to consist of 60 percent tin and 40 percent lead. These days, it is possible to get a lead-free solder wire, which is favored by many who prefer safer and environmentally friendly products. It is also possible to get halide-free and rosin-free solders. Choosing a solder may sound simple, but there are certain factors you must consider to make sure that you can get the right product. Various types of solders are designed for different tasks, and during the selection process, you need to take note of the flux content, size, and the lead content. Here are a few tips to help you choose...

Uses of Low Temperature Solder
A low-temperature solder may be necessary in a surface mount assembly of products which cannot go through harsh temperatures and conditions. Low temperature soldering may be beneficial in certain applications because it may help reduce or eliminate the need to use lead. Likewise, it is preferred for its step soldering capability and thermal shock reduction. Low-temperature SMT soldering can be accomplished using the right alloy and process to help reduce the total cost of ownership while ensuring the delivery of reliable solder joints.Low temperature soldering is used in many applications requ...

Summary Of The Flip Chip Package Design
The term "flip chip package design" includes many different methods. Each method is different in many ways, and the application is different. For example, the choice of type of circuit board or substrate, whether it is organic, ceramic, or flexible, determines the choice of assembly materials (bump type, flux, bottom filler, etc.) and, to a certain extent, the choice of equipment required. In the current situation, each company must decide which technology to adopt, which process components to choose, which research and development to conduct to meet the needs of future products, and how to mi...

Lead-Free Soldering
Environmental crises and outcries are leading to innovations across all industries, seeking reforms that are environmentally friendlier. In the electronics industry, this has led to lead-free soldering. Why the objection to using lead? In the ‘90s, in a spell of acid rain, the lead from the electronic waste dissolved and seeped down to the ground waters, polluting it all. Widespread grievance pushed the industry into seeking solutions that did not contain this harmful metal, leading to the creation of lead-free solder bars. In this blog, you shall get to know some points about lead-free ...
