Tips on Solder Paste Application to a PCB
Solder paste is a crucial aspect of a PCB assembly, especially when reflow soldering techniques are used. It is typically a mixture of specially formulated flux and solder spheres. Hence, the solder creates a type of paste that can be integrated onto the surface of a PCB without causing problems with how the board should function. There are different types o...

Benefits of Moving to Lead-Free Electronic Assembly
Since the past decade, there has seen a gradual, yet consistent, shift from traditional Tin/Lead towards lead-free electronic assembly. The RoHS and WEEE Directives have been consistently driving the electronics manufacturing industry towards the use of lead-free solders, but the concept still faces some opposition from the market. Adopting lead-free alterna...

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 water...

SOLDER PASTE FOR LOW-TEMPERATURE PB-FREE APPLICATIONS
Imagining the modern electronics industry without the existence of solder is pretty much like trying to picture the human body without its nerves. Solder plays the critical role of holding all the components in a PCB assembly together while ensuring that nothing obstructs the flow of electricity from one point to another. Traditionally, Tin lead solder paste...

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 tha...

A Guide for Lead Solder Paste
PCB assembly requires high-quality materials and products that can ensure proper connection between the surface mount components and the printed circuit board. One of the necessary materials for this job is the solder paste. Solder paste is a combination of fusible metal alloy, commonly used while creating joints during the manufacturing of printed circuit b...
