PCB Manufacturing - Processing Without the Problem of Voids

Written by Angie Brown
Posted on January 10, 2022 at 10:12 AM

What is a void in the printed circuit board (PCB) world? A void is an un-plated area within the hole wall of the PCB drilled plated hole. Voids in hole barrels can be equally problematic in all types of PCBs. The number of layers contained within the PCB plays a part in the cost of the completed circuit board. The more layers within the card the more cost is added for manufacturing. However, a two-layer part can also be expensive to scrap.

Printed circuit boards (PCBs) are the heart of electronic products as they provide the conductive pathway for all the electronic components to connect and function together. As electronics become more advanced and complex, PCBs are having multiple layers sandwiched together to establish all the necessary connections.

Incorporating PCBs and LEDs into an Outdoor Overmolded Cable Design

Written by Steven J Goodman
Posted on October 4, 2021 at 10:03 AM

Outdoor cables are used in commercial, industrial, and residential applications where they are exposed to a variety of adverse conditions. To survive a lifetime’s worth of abuse, outdoor-rated cables must be designed to stand up to the elements, rough handling, excessive moisture, extreme temperatures, and contaminants like sand or dust. Having an overmold in the design of the cable assembly, the cable terminations can be sealed and ruggedized allowing for several design risks associated with outdoor use to be addressed in an economical fashion.

PCB Data Sets: What You Need to Know

Written by Angie Brown
Posted on August 24, 2021 at 10:49 AM

I love looking at data. Sounds weird, right? I guess it is because I have been working in the industry for so many years. I have seen the technology changes, and I just find it fascinating. In this blog post, we will recap the past, which some of the time creeps its way back to Epec, the present, and the future of printed circuit boards (PCBs).
Let’s get to it.

Supply Chain Challenges on the Electronics and Manufacturing Industry

Written by Kendall Paradise
Posted on August 23, 2021 at 10:13 AM

The last 18 months have been some of the most challenging that many of us have had to deal with both personally and professionally. It has often felt like we were riding waves, coming closer to things getting a little more normal, only to have them change radically. Looking forward to the next 18 months, I don’t see those changes getting any easier for us or our industry.

PCB Mechanical Drilling vs. Laser - Aspect Ratios and Drill Sizing

Written by Angie Brown
Posted on June 29, 2021 at 9:12 AM

Printed circuit boards (PCBs) require holes to be drilled through or partially through laminate materials. These holes are used to create continuity between the top and bottom or to a mid-layer on the PCB. The holes allow traces, pads, and copper polygons to be connected throughout the different layers of the board.

Common PCB Quality Issues and What to Inspect For

Written by Angie Brown
Posted on June 14, 2021 at 10:10 AM

As our world continues to evolve to an online buying market for everything for our homes, schools, and offices, you may have noticed in some cases, the quality is not exactly what you thought you saw and bought online. We have all had that men’s XL shirt we bought for dad’s birthday arrive only to fit our 7-10-year-old, or the gift for Christmas arriving in January. Is it cost vs. quality, convenience vs. going out shopping, or is it the ongoing COVID-19 situation?

Circuit Board Material Tolerances that Affect Manufacturing

Written by Angie Brown
Posted on June 2, 2021 at 9:57 AM

Within the first few pages of IPC standard for printed circuit boards, there is a reference table 1-2 that is called “Default Requirements.” When reading the standard looking for some guidance, one may question “default” as part of a requirement. Often, when we receive circuit board production files there is not enough information from a manufacturing standpoint but certainly enough to quote.

Understanding How Solder and Coatings Impact PCB Shelf Life

Written by Sherry Clowers
Posted on May 18, 2021 at 10:13 AM

Printed circuit boards (PCBs) may go through extreme wear-and-tear based on environmental factors. They may be placed in applications where there will be fluctuating temperatures, extreme heat, extreme cold, high humidity, salt water, and excessive moisture.
