When we use electronics in commercial settings, one of the major factors that must be taken into consideration is the different temperatures that the circuitry and wiring will experience. Not every electronic device will be used in a stable indoor working environment like an office space.

Around the world, different industries have applications and equipment where there will be changing temperatures, humidity, or moisture that can impact how a component operates or processes signals. There may also be instances where a product needs to be at a certain temperature so that it may be processed, such as a liquid chemical or food product that has to be at the right temperature, so that it will be fluid enough to be packaged into containers.
From controlling condensation on electronics to keeping food warm, flexible heaters provide many advantages to commercial industries such as medical, electronics, aerospace, food and beverage, and refrigeration. Silicone and Kapton® heaters are the most common heaters used due to their flexibility, great thermal transfer, rapid warmup and varying temperature applications.
Manufacturers requiring localized heating for their applications turn to the advantages of flexible heaters that are mounted to components and equipment. These heaters can provide low level or high-level heat at varying temperatures to offer the appropriate thermal transfer based on the applications.
Whether used in the aerospace industry to de-ice equipment, or the food industry to bring ingredients up to a suitable temperature, flexible heaters provide the right amount of generated heat based on the application. These types of heaters can be attached to smooth, bulky and curved equipment in different sizes and functions.
ENEPIG (Electroless Nickel, Immersion Palladium, Immersion Gold) was derived out of the need to combat the challenge with the immersion gold process and Black Pad Syndrome. Black Pad (the hyper corrosion of underlying nickel) was baffling both PCB assemblers and manufacturers. After much analysis, the root cause was determined to be the nickel deposit.
Solving solderability issues for printed circuit boards (PCBs) can be a real hassle. Nothing is more frustrating than having lined up all your materials for an assembly, only to start running the package through reflow and discover that the solder paste is wetting poorly to the pads. Immediately, the profile is checked to confirm proper parameters.
For customers and suppliers along the PCB manufacturing process, non-conformances will, unfortunately, happen from time to time. A non-conformance consists of receiving an order for printed circuit boards that do not meet your specifications or industry (IPC) standards. While dealing with these issues is obviously essential, the solution is sometimes not obvious and can put on-time delivery to your customer at risk. It is imperative that your circuit board supplier can deliver conforming product as soon as possible, which means having the procedures to get there.
With the introduction of ISO 9001:2015, which specifies requirements for quality management systems, the statement “quality management system documentation shall include a quality manual” no longer need apply. Many celebrated this as a reprieve from previously having to fully document their quality management system. However, eliminating the supplier quality manual altogether could be a dangerous takeaway on the new standard’s intention.
I can remember the first ‘incident’ of black pad, years ago, when Epec started to use the electroless nickel immersion gold (ENIG) process. We didn’t notice the issue at the time, as it is not evident on the bare board, but received the complaint from assembly as it was later identified on completed assemblies.
