  1. Liquid Solder for Circuit Boards – Learn the Basics Solder comes in many different formulations for different purposes, and you need to consider what it is made of and its application when choosing the right product for circuit boards. Electronics require a special form of solder that will ensure the integrity and safety of circuits. To keep your assembly in good condition, make sure that you use only an appropriate product, like liquid solder. You are likely to come across two types of liquid solder for circuit boards and these are lead-based and lead-free. Their practical difference lies in their melting temperature. Lead-based solder has been widely used in the past, yet it still persists to this day, even though the negative effects of lead exposure are well known. The reason is because certain applications require the high-reliability, strength and dependability of lead-based formulations, such as in medical or military/aerospace applications. Lead-based solders are typically made of a mixture of 60 percent tin and 40 percent lead (60/40), which melts at about 180 to 190 degrees Celsius. Lead-free solder for circuit boards are becoming popular in different industries that are seeking healthier working environments for their employees and safer products for customers. If you are building commercially available electronics, consider using this type of solder to pass EU standards. Take note that its melting point is higher, so it might be challenging to work with, especially if you are used to lead-based formulations. When choosing liquid solder for circuit boards, be sure to consider your electrical requirements and the formulation’s electrical reliability. Take note of manufacturer recommendations on which assembly type the solder will be most effective. Some types of liquid solder for circuit boards are formulated differently than conventional products. They are considered environmentally friendly, yet capable of delivering unmatched soldering performance. These liquid solders are either water-based or alcohol-based fluxes that enhance defect-free soldering, provide excellent wetting, and ensure high line throughput for an array of applications. Some formulations come with rosin-free and no-clean properties. No-clean, halide-free flux ensures the highest-quality defect-free soldering that prevents solderballs from forming. The formulation is thermally stable to reduce solder bridging, too.
