Researchers from Singapore recently developed a glue that hardens when a low voltage is applied to it. The electric glue, nicknamed “Voltaglue,” offers promising adhesion for a number of applications because it’s not affected by environmental conditions.
Scientists note its usefulness when bonding materials under water and replacing sutures during surgery in human tissue. In the near future, for example, Voltaglue could aid in underwater repair work for ships and pipes. Voltaglue could also replace 20 minutes of careful suturing in human tissue with a two-minute application.
In all applications, the hardness of the glue is adjusted by the length of time the voltage is applied.
Glues that can cure and be uncured through electricity would allow automakers and shipyards to assemble and disassemble parts with ease, minimizing the need for bolts, nuts and screws. Reversible glue also opens up new possibilities in the global adhesives market in transportation applications, an industry worth about $3.3 billion in the United States alone.
This innovative research was published in Nature Communications, a peer-reviewed scientific journal under the Nature Publishing Group.
Considering ESD flooring? Ever compare the burn-in oven process with ESD flooring versus no ESD flooring? You might be surprised by who wins the match according to a recent process analysis.
The burn-in process with ESD flooring can be completed in three steps:
- Operator places the burn-in board on the ESD cart.
- Operator rolls the cart to the oven.
- Operator removes the board from the cart and places it in the oven.
Pretty straightforward, right? What about the no-ESD floor scenario? With no ESD floor, the process is nearly five times as long! From start to finish, the operator in this scenario undergoes 14 steps from connecting a wrist-strap ground cord to the ground to disconnecting the cord.
The 14-step process also increases the risk of product defect, scrap as well as dropped product. But, you can minimize the risks with ESD-safe floor tiles from Desco. Configure your workspace easily with Desco’s patented interlocking edges.
When it comes to safety and process improvement, just remember 14 is more than three. Who do you want in your corner?
Has your tip lost its wettability? If it’s black or dark blue like this, it’s probably undergone oxidation, and solder won’t wet to the surface.
What does this mean for your application? It means your tip can’t supply heat to the part being soldered. It may contact the part over a small area, but it won’t transfer heat well enough to get the job done.
But, don’t despair! Although lead improves the wetting action of solder, you can improve the life of your tips when using lead-free solder by following these five, simple do’s and don’ts:
- Don’t leave your soldering iron on for long periods of time without making connections.
- Don’t set your tip temperature higher than 400°C (750°F).
- Do use a flux with an aggressive activation level and long activation window.
- Do keep the entire tip surface tinned with a coating of solder when not in use.
- Do use the Hakko FS-100 Chemical Paste to re-tin your tip if it’s become oxidized and solder isn’t wetting the tip. This paste is designed to remove heavy tip oxides without corrosive chemicals like zinc chloride. You can use the FS-100 with the FT-700 Tip Polisher to restore solderability to dewet tips.
Just practice these few good tips, and the good tips you need for reliable solder joints will be in the bag.
