PCB Manufacturing Process

Below are some images from the printed circuit board manufacturing process. Including, drill, plating, and final fabrication. All our circuit boards go through intensive testing and quality control during each step of the manufacturing process.

See our blog post titled Printed Circuit Board Manufacturing: Then and Now to see how the circuit board manufacturing process has evolved over the years.

Inner Layer
Inner layer core shown after etch\dryfilm strip processes have been completed. The core is now ready for post etch punch.
Laser Drill
Laser drill is necessary for today growing technology, drilling the smallest micro-vias using a beam of light 20 microns (1 Mil) in diameter. High influence beams can cut thru metal and glass creating the tiny via hole.
Post Etch Punch
Punching core material is the only acceptable method of building precision tooling which must remain accurate in a production atmosphere.
Press Room
Press lines for manufacturing quality, high layer count PCBs with consistency and in a timely manner.
Drill
CNC machines are complete with drill and profile routing software allowing for high performance and throughput.
Plating
Automated plating lines serving quick turns and production of small to high volume.
Strip - Etch - Strip Line
Production panels proceed to etching to remove unwanted copper and into the strip line to remove protective film.
Automated Optical Inspection (AOI)
Using the latest in optical inspection equipment on internal and external layers allows for minimal fallout on final product.
Final Fabrication (Routing & Scoring)
Routing and scoring to precise dimensions within supplied tolerances are the final steps prior to electrical testing. Constant monitoring by engineering ensures parts will meet your specifications.
Electrical Test
Flying Probe testers are used to 100% electrical test all PCBs on site at manufacturing.

America's Oldest. A History of Innovation.

Over the past 70 years, the electronics manufacturing industry has changed dramatically as the industry continues to adapt to evolving demands and technology. Epec is at the forefront of innovation, with the expertise and agility to move at the speed of today’s businesses. At Epec, the customer comes first, and everything we do must be put through that filter. Whether it is developing e-commerce platforms to make it easier to work with us or creating a new product introduction (NPI) process that helps our customers get to market faster, we must focus on building the new. By doing that every day, and by always making the customer our top priority, we plan on being here for another 70 years and then some.
