Etch compensation is a process used in the design of printed circuit boards (PCBs) to adjust the trace widths to compensate for any changes that occur during the PCB manufacturing process. When PCBs are manufactured, the etching process used to create the copper traces on the board can cause some amount of variation in the width of the traces. This variation can be caused by factors such as the thickness of the copper, the quality of the etching process, and the chemical composition of the etchant.

In printed circuit board (PCB) designs, through holes are used to connect components and conductors on different layers of the board and can be divided into two types: plated and non-plated through holes.

I am still amazed at how far technology has brought us throughout the years. When asked about printed circuit boards (PCBs) and what they go into, the answer is everything you can imagine, everything you use in most cases.

At the conclusion of our webinar, PCB Manufacturing Facilities: Certifications, Compliance, and Security - we had several questions submitted to our presenter, Ed McMahon, CEO at Epec. We have compiled these questions into a readable format on our blog.

As the oldest production printed circuit board (PCB) company in North America, perhaps in the world, the 70+ year story of Epec Engineered Technologies is connected to the development of the PCB and the electronics industry. Epec’s storied history also includes delivering PCBs for the Apollo 11 spaceflight.

So, let’s talk about non-recurring charges, better known as NREs, that are applied to most new and new revision first-time orders for manufacturing of printed circuit boards (PCBs). These charges help aid in several crucial steps for manufacturing with a cost of processing, programming, testing, and manpower to deliver a quality product.

As a printed circuit board (PCB) manufacturer for more than 70 years, we have worked with thousands of customers to provide quality products in prototypes of a few pieces to many tens of thousands of circuit boards repetitively.

From a printed circuit board (PCB) manufacturing supplier’s point of view, often we are consulted about design and layout at the concept phase. Over the past many years, we have seen an increase in customers asking to assist with design, layout, and modifications to the circuit board. From this repeat request, we developed an engineering team to make it happen.

When it comes to printed circuit boards (PCBs), the bare board is always where customers look to cut costs. Unfortunately, we often see this request after the design has been completed and we have the Gerber files in hand to quote the printed circuit board.

Mil-aero devices live in a special place in the worlds of design and engineering. These are devices that are often subjected to extraordinary environments. They have extreme requirements, and they often must function in the harshest environments of the world.
