4 Useful Static Eliminators to Keep your Equipment from Catastrophic Disaster

Everyone has had plenty of experiences dealing with electrostatic discharge-reaching out a hand to open the car door on a dry winter day and hesitating, because you know that zap is coming. Annoying isn’t it? Unfortunately, ESD can be a lot more harmful than that. Without proper prevention, it could damage a computer to the point of no return. The zap you felt when you opened the door was at least 2,500 volts of ESD, caused by the transfer of electrons from one surface (the door handle) to another (your hand). Charges as weak as 200 volts can severely damage your computer, and since they are below the threshold of human feeling, you might have no idea it’s happening. Catastrophic failure, damage to your computer that cannot be undone, is commonly due to ESD, and it can be direct or latent. Direct isn’t really a problem to anyone but manufacturers, since it is usually detected in initial testing. Latent catastrophic failure is what you should worry about. Low-voltage static charges may be slowly causing damage to your computer system, and may not show symptoms for weeks or even months. Then, suddenly, out of nowhere, you’ve got a computer that won’t turn on and can’t be fixed.

Advantages of AC-DC ‘Brick’ Power Modules

Compact DC-DC converters have made their way into millions of electronic products and systems. The vast majority of these depend upon an AC-DC power supply (metal box or chassis-mount) to convert the AC into a DC voltage from which the converters can operate. In addition, regulations have mandated that these power supplies include Power Factor & Harmonic Correction (PFHC) to maximize the available power from the power grid. Add to this the need to be as small as possible and to operate with in harsh ambient temperatures and the designer is faced with a problem that is not easily solved.

Advanced Ceramic (AlN) Heaters For Semiconductor Backend Packaging Applications

As electronic devices become increasingly smaller, lighter, thinner and more powerful, the demand for more precise and faster packaging technology has increased. Despite the difference in various packages available in the industry, the technology of packaging processes share common steps. In general, these steps include: die preparation, die attach, wire bonding and encapsulation. Among these steps, die attach is one of the most challenging processes, as it involves material compatibility, placement and dispensing accuracy, precision process temperature profile and a short cycle time…

Safety Comes First When Using Electric Heaters

We rely on electric heaters to warm our homes, offices, water and food, and manufacturers depend on electric heating for numerous industrial processes, such as plastic and rubber injection molding, packaging heat sealing and die casting. All electric heater appliances contain some form of heating element that acts as a resistor to convert the energy of an electrical current into heat. The heater can be as simple as the resistor welded or brazed into a metal flange or plug that contains an electrical terminal, or a number of resistors could be bundled together inside a larger unit. Due to the obvious hazards of bodily burns and fire damage, proper precautions need to be taken when using any kind of electric heater…

Rapid Cooling of Aluminum Nitride Heaters

Single Iteration, a division of Watlow, has conducted preliminary concept generation and evaluation for several alternative solutions for providing rapid cooling of AlN based heaters. Cost/benefit analysis of the various alternatives indicated that forced air cooling would be preferred for many applications of the latest AlN heating technology…
