Are your solder tip erosion rates far too high?

Solving solder wire challenges with Koki’s 72M series

Similarly to other industrial sectors, electronics manufacturers are always looking for solutions to ongoing issues and more efficient production methods.

One such demand is the need for more cost-effective solder wires. Typically, standard un-leaded solder alloys used for hand soldering wires are very aggressive and ‘eat’ soldering iron tips. As components get smaller due to design and space limitations, soldering iron tips have become more sophisticated and much more expensive…

Are you experiencing solder joint voiding issues? Solve them with Koki’s S3X58-G803 solder paste

One of the most significant challenges in the electronics industry is the formation of voids in solder joints. Voiding typically occurs when flux or solvent in the paste becomes trapped in the joint, or paste oxidises, and empty spaces are created within the joint. Too many voids in a solder joint will impact the joint’s reliability, so it’s important this issue is avoided.

Are you struggling with poor wetting from your current solder paste?

If you’re struggling with oxidised pads and components, combat the challenge with Koki’s S3X58-M500C-7 powerful wetting, no-clean solder paste

Most engineers and operators have experienced poor solder wetting – an extremely common challenge in the electronics industry. Poor wetting can be caused by a number of different issues including low paste volume or inconsistent soldering temperatures, but mostly this is due to oxidisation or tarnishing of the solder joints caused by poorly stored or very old components, often referred to as ‘grey’ components…

What is GWP and how can it be reduced?

Everyone has heard of global warming, but beyond changes to the weather – like freezing winters and sweltering summers – many people don’t really know what it means.

Global warming is a gradual increase in the overall temperature of the earth’s atmosphere. NASA says that global warming can be attributed to the greenhouse effect, which occurs when the atmosphere traps heat radiating from Earth. Some types of gases block heat from escaping the atmosphere and are long-lived, remaining semi-permanently in the atmosphere without responding physically or chemically to changes in temperature.

Carbon dioxide, methane, nitrous oxide and chlorofluorocarbons are the most prevalent greenhouse gases and while some, like carbon dioxide, occur naturally, others such as chlorofluorocarbons are synthetic and their manufacture is heavily regulated.

One of the methods for measuring the impact a gas will have on the atmosphere is Global Warming Potential (GWP). GWP is used to represent the equivalent of C02 being released into the atmosphere, where 1kg of C02 = a GWP of 1. For companies manufacturing gases, and for those purchasing and using them, it is critical to manage environmental impact by keeping the GWP as low as possible…

Why we should pay more attention to new F Gas regulations

Regulations around the use of F-gases (also known as fluorinated gases) have become increasingly stringent over the last few years, and many businesses are unknowingly inadvertently breaking laws.

F-gas is most commonly thought of as an issue for the refrigeration and cooling industries, where their use is most prevalent. But, these gases can also be present in solvents, which affect a much wider variety of industry sectors. As a result, many businesses are unaware that these significant changes apply to them…

nPB Sunset Date set for 4th July 2020

Leading US industry body the American Conference of Governmental Industrial Hygienists (ACGIH) has changed its recommended threshold limit value for n-Propyl Bromide (nPB) from 10 ppm to just 0.1 ppm, amid concerns over health risks to workers.

In addition, nPB has also been added to the candidate list for inclusion in Annex XIV of European REACH regulations as a ‘Substance of Very High Concern’ (SVHC).

Solvent Cleaning Myth Busting!

A great deal of misconception still surrounds the use of solvent cleaners, and many businesses are using aqueous solutions just because they think they’re safer, rather than considering the chemistry that is most appropriate for their needs. While solvents do have a controversial history, the solvents of the 80s and 90s have been left in the past, and the current new generation of chemicals are just as safe as the aqueous solutions people have become accustomed to. So what are some of the most common myths about solvents, and what’s the truth? Continue Reading
