Epec's Blog | Electronics Manufacturing Solutions

This blog post is not the usual topic you find on Epec’s company blog. We are normally blogging about technology solutions focusing on issues that can help our customers, but as a company, Epec does a lot behind the scenes for their employees that go unnoticed.

Avoiding Expensive PCB Materials & Processes

Printed circuit boards are only one component of an entire assembly designed to meet the best cost-to-performance ratio possible. The finished product into which the PCB is installed must meet a price point that compares favorably against competing products, so the lower the expenses, the more money your product returns. In order to make the best choices during the design cycle, it is important to first understand what drives the primary costs.

Packaging for user interface assemblies is the last step in the manufacturing process, but not a step that should be rushed. Epec pays as much attention to packaging detail as we do to design and manufacturing of custom assemblies. Because each assembly part number is customized, each has different size, mass, and shape. However, styles of user interfaces can be grouped into several categories. Experience has shown the type of packaging that works best is based on complexity of construction, shape, size, mass and shipped unit volume. No one packaging solution works for every assembly style.

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.

Engineering 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".

When 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.

One 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.

When 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.

Flexible 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.
