In today's battery and charger market, most companies typically provide either battery pack assemblies or battery pack chargers, as opposed to providing both. In the past, buying a battery from one source and a charger from another worked just fine when using the older NiCd batteries with overnight chargers. However, due to new battery chemistries and the increasing need for faster charge times, careful matching of the charger to the battery has become essential. Without proper battery and charger matching, aspects such as safety, cycle life, and run-time may be greatly affected.
Read MoreEngineering in most industries, still tends to be primarily dominated by males. When I first entered the field of Printed Circuit Board (PCB) engineering, it was a bit intimidating. This was because the men always outnumbered the women. I felt we were graded on separate standards "Men vs Women".
Read MoreWhen creating your optimal circuit board design, one factor that must be considered is the solder mask and whether to go with matte finish solder mask or gloss finish mask for your final product. Usually, most designers don't specify their preference and end up leaving the decision to the PCB fabricator. Most fabricators will likely default to a gloss surface finish, the more popular choice of the two.
Read MoreOne point that anyone involved with cable assemblies understands is that "every electronic or mechanical component will eventually reach the end of its life cycle". This blog post will define cable assembly obsolescence as the point in an assembly’s life cycle when it is either no longer in a usable state, meaning it is not functioning as it was designed, or there is no longer a use for the cable assembly due to technology changes.
Read MoreWhen we sat down in 2005 to develop our IT infrastructure plan for the company, I was unsure of why we spent so much time evaluating every investment in terms of what we would do in case of a disaster. Well, this winter, I found out why that was so important.
Read MoreFlexible PCBs use one of two polyimide flex core constructions: adhesive-based or adhesiveless. The difference lies in how copper is bonded to the polyimide core, which directly affects thickness, flexibility, thermal behavior, reliability, and cost. Selecting the correct construction requires balancing electrical, mechanical, and environmental design requirements.

Read MoreThis blog post addresses custom user interface testing in terms of functional test schemes that are completed prior to shipment. Generally, the first user interface assemblies shipment are for First Article acceptance testing where customers fully examine the first units for mechanical and electrical compliance to all engineering drawing and specifications.
Read MoreProper lithium-ion battery storage has a direct impact on capacity, lifespan, and overall battery pack reliability. Environmental conditions, especially temperature and state of charge, are more influential than the charge cycle alone. Storing battery packs at partial charge in controlled conditions helps preserve performance and prevent irreversible damage.
Read MoreWhen we think of manufacturing in the 21st Century, we picture automated machines rapidly pumping out new products with ease. So why can't the process of complex wire harness manufacturing become fully automated as well? To answer this question, we need a deeper understanding of cable harnesses and how they are prepared.
A cable harness, also referred to as a wire harness, cable assembly, wiring assembly, or wire loom, is a grouping of wires and/or cables that are used to transmit signals as well as provide electrical power if needed. The wires and cables are joined together using a combination of straps, cable ties, cable lacing, tubing (either shrink tubing or non-shrink tubing), sleeving, electrical tape, conduit, and braided extruded string.
