Three Options to Adding a Cable to a Rigid PCB Front Panel HMI

Written by Steven J Goodman
Posted on July 31, 2020 at 9:23 AM

Front panels, bezels, and other types of human to machine interface equipment use several circuit technologies to operate. These circuit types usually involve some form of printed or etched traces using conductive materials like copper and conductive ink. These custom layouts are routed across insulating sheets and films, eventually becoming circuit boards and flex circuits. Dome switches, LEDs, and touchscreens can be added to these everyday circuit boards, bringing them to life as a high-technology HMI solution.

PCB Cost Drivers: Simplify for Lower Circuit Board Cost

Written by Al Wright
Posted on July 21, 2020 at 9:12 AM

When you are designing a printed circuit board (PCB), your customer or boss does not typically hand you a blank check. You may occasionally be fortunate enough to have a customer with deep pockets, but most products are very cost-sensitive, and your board design will need to come in at or below budget. This post will go over some of the things you can do to achieve a cost-effective design. Its focus will be limited to a handful of higher-end design options.

How to Effectively Manage High Technology Quick-Turn PCBs

Written by Ed McMahon
Posted on July 15, 2020 at 9:12 AM

Traditionally, quick-turn printed circuit boards have been used for PCB prototyping and low-volume production in the electronics industry. Many companies have developed very low-cost, low-option Internet programs to get customers low technology printed circuit boards very inexpensively. However, in today’s evolving electronics industry, quick-turn printed circuit boards are now part of every stage of the product development lifecycle, from initial concept development to full working prototypes to getting the production product to market faster than any of their competitors.

Adding a Standard Stack-up to Your PCB Documentation

Written by Al Wright
Posted on July 9, 2020 at 9:32 AM

As somebody whose job it is to analyze several multilayer PCB designs per week, I find it surprising whenever I receive a data package that does not include a defined lamination stack-up. The way that the layers are constructed can affect the PCBs performance, so these packages feel like they are missing a potentially important piece of information.

PCB Tolerances for Routing, Drilling, and Chemical Plating

Written by Jim Marsh
Posted on June 24, 2020 at 9:42 AM

Having been involved in the printed circuit board (PCB) world for nearly four decades, I continue to see the same drawing mistakes. When declaring PCB tolerances in any given design, the PCB designer must take into consideration the manufacturing of the board itself. In this blog post, we will review some of the issues we commonly see in PCB designs that are not allowing the proper tolerances for the routing, drilling, and plating processes.

Printed Circuit Board for RF/Microwave Applications: Laminate Trends

Written by Ed McMahon
Posted on April 9, 2020 at 8:49 AM

Many applications today send signals between two devices to provide data or to perform a specific function. These signals may consist of radio frequencies (RF) or microwave frequencies. Typically found in the communication industry, RF/microwaves are common for satellites, radar, and navigational systems. Yet, they can also be found in smaller applications, such as garage door openers, security key card terminals, wireless alarm systems, and handheld warehouse inventory scanners.

What Are Gerber Files and What Are They Used For?

Written by Michael Concepcion
Posted on March 26, 2020 at 10:22 AM

After an engineer has finished their circuit design for a printed circuit board (PCB), the next step is to enter the schematic details into a computer-based schematic capture program such as Altium, Eagle, or OrCAD. The finished printed circuit board will provide the physical assembly and interconnection platform for the various electronic components required by the schematic.

Advanced and Non-Standard PCB Manufacturing Capabilities

Written by Al Wright
Posted on January 16, 2020 at 9:12 AM

There was a time when the PCB manufacturing industry included a fair number of bucket shops, so called because much of their processing was done in small portable tubs filled with etchants, solvents, and other mysterious solutions. They cranked out very basic, low-cost, low-complexity PCBs, using equipment and methods that were questionable at best. Their business and environmental practices were often similarly questionable.

DFM For Your Quick-Turn PCB Order

Written by Al Wright
Posted on July 31, 2019 at 9:12 AM

Design for Manufacturing (DFM) is critical to the success of your PCB order. Features that make your circuit board difficult to build add cost to your product and can increase the scrap rate. If you have designed a PCB that is more complex than usual, it is useful to submit files to your fabricator for review before placing your order so you will have some time to address any issues that might delay production.
